I read that I should find my sqlite db in this path:
~/Library/Application Support/iPhone Simulator/YOUR-IOS-VERSION/Applications/UNIQUE-KEY-FOR-YOUR-APP/Documents
But the folder is empty. When I run my app in the simulator I am able to query the db.
The db is originally located in the resources folder of my app.
I am working with xcode 3.2.6 and OS X 10.6.8
IS there somewhere else where I could look for it?
Many thanks.

In order to access your resources database in the Documents folder of application, you first need to copy it there when the application launches.
If the database file is in the resources folder in your xcode project, it is not copied automatically into the documents directory of the app.
To do so you can use:
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSError *error;
NSString *databasePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"YOUR_DB_IN_RESOURCES"];
[[NSFileManager defaultManager] copyItemAtPath:databasePath
toPath:[NSString stringWithFormat:#"%#/%#",documentsDirectory,#"YOUR_DB"]
error:&error];
You will then be able to access the database that's now in the documents folder using your existing code ([pathDB UTF8String] should point to the documents directory and not the resources).
As you mentioned, you can still use the DB in the resources, but it will be wiped every time you relaunch your app. The trick is to copy the db into your documents folder where it will remain until the app is manually deleted from device (the documents folder is also kept during app updates, so your db remains when users update the app).
Hope this helps :)
I'm trying to create an SQLite3 database file through Objective-C at run time. I am trying to create a table called "tblStore". I want the field names to be called "strStoreNumber" and "strStoreReg". I'm new to iOS and SQLite, so I'm having a hard time finding the syntax to perform this. In addition to creating the table, I want the created table to reside NOT in the app bundle, but rather it would reside/be stored somewhere on the phone. The table needs to be readable/writeable. I've done some reading on "user sandbox" and also a "documents directory". I'm not sure I understand the difference between the two. Ideally, my app would use a button to take input from Text Fields. After the input from the texts fields is put into strings, a check would be done to see if my "tblStore" SQLite table exists, and if it doesn't, the table will be created.
To recap:
1. What is the syntax for Obj-C/SQLite to create a table called "tblStore" with the fields "strStoreNumber" and "strStoreReg"?
2. Where should the db file reside? I need to read from and write to the tblStore db file.
3. What is the difference between a "user sandbox" and a "documents directory"?
This is what I have currently:
-(IBAction)setInput:(id)sender
{
NSString *strStoreNumber;
NSString *strRegNumber;
NSString *tableName = #"tblStore";
NSString *dbStrStore = #"strStore";
NSString *dbStrReg = #"strReg";
strStoreNumber = StoreNumber.text;
strRegNumber = RegNumber.text;
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths lastObject];
NSString* databasePath = [documentsDirectory stringByAppendingPathComponent:#"tblStore.sqlite"];
// NSString* databasePath = [[NSBundle mainBundle] pathForResource:#"tblStore" ofType:#"sqlite"];
if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK)
{
NSLog(#"Opened sqlite database at %#", databasePath);
char *err;
NSString *sql = [NSString stringWithFormat:#"CREATE TABLE IF NOT EXISTS '%#' ('%#' TEXT PRIMARY KEY, '%#' TEXT);", tableName, dbStrStore, dbStrReg];
if (sqlite3_exec(database, [sql UTF8String], NULL, NULL, &err) != SQLITE_OK)
{
sqlite3_close(database);
NSAssert(0, #"Table failed to create.");
}
//...stuff
}
else
{
NSLog(#"Failed to open database at %# with error %s", databasePath, sqlite3_errmsg(database));
sqlite3_close (database);
}
NSString *querystring;
// create your statement
querystring = [NSString stringWithFormat:#"SELECT strStore, strReg FROM tblStore WHERE strStore = %# AND strReg = %#;", strStoreNumber, strRegNumber];
const char *sql = [querystring UTF8String];
NSString *szStore = nil;
NSString *szReg = nil;
sqlite3_stmt *statement = nil;
if (sqlite3_prepare_v2(database, sql, -1, &statement, NULL)!=SQLITE_OK) //queryString = Statement
{
NSLog(#"sql problem occured with: %s", sql);
NSLog(#"%s", sqlite3_errmsg(database));
}
else
{
// you could handle multiple rows here
while (sqlite3_step(statement) == SQLITE_ROW)
{
szStore = [NSString stringWithUTF8String:(char*)sqlite3_column_text(statement, 0)];
szReg = [NSString stringWithUTF8String:(char*)sqlite3_column_text(statement, 1)];
}
}
sqlite3_finalize(statement);
lblStoreNumber.text = szStore;
lblRegNumber.text = szReg;
}
When I run my app, I get the following errors:
2012-05-10 14:58:38.169 CCoDBTry[355:f803] Opened sqlite database at /Users/Matt****/Library/Application Support/iPhone Simulator/5.1/Applications/5DB7A218-A0F6- 485F-B366-91FD2F9BC062/Documents/tblStore.sqlite

I appreciate anyone who takes the time out to explain some of this stuff, as I am very new and have been unsuccessful in accomplishing some of the things I've tried. Thanks so much for the help!

sqlite is a pain if you dont know what you're doing. I also had some problems with sqlite c functions but then i decided to use sqlite wrapper.
FMDB and BWDB are good and easy to use sqlite wrappers for objective c. I suggest you use one of those .
Note that BWDB is in a lynda.com tutorial (this one) and if you don't find it on the web...leave a comment and i'll upload it somewhere.
edit: the only place you can write stuff in your app is in your documents directory...so..it plain terms...if the db is not in your documents directory..is read-only..also..when you read/write to your db..the OS copies the db in the documents directory..and does all the reading and writing there so you can have a db in your app bundle but you can't edit that one...so you'll end up with 2 db.I had the same problem myself..and i fixed it by merging the 2 db when i updated the app
edit2: i uploaded BWDB final project ( you have your wrapper there and project to see how it works)
You can use following code to get the database created at in Documents folder. Just pass a path in documents folder and the function will copy the sqlite database in Documents folder at the given path if required. You can then use this path to create and query database tables.
+ (NSString*) createDatabaseIfRequiredAtPath:(NSString*)databasePath {
if (databasePath == nil)
return nil;
NSString *path = [NSString stringWithFormat:#"%#/%#", databasePath, kMainDBName];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error = nil;
if ([fileManager fileExistsAtPath:path] == NO)
{
// The writable database does not exist, so copy the default to the appropriate location.
NSString *defaultDBPath = [[NSBundle mainBundle] pathForResource:kMainDBName
ofType:nil];
BOOL success = [fileManager copyItemAtPath:defaultDBPath
toPath:path
error:&error];
if (!success)
{
NSCAssert1(0, #"Failed to create writable database file with message '%#'.", [ error localizedDescription]);
return nil;
}
}
return path;
Is there a specific reason you'd like to use SQLLite directly, as opposed to using CoreData? CoreData uses an SQLLite database but is itself a higher-level API, and particularly with table views and such, you get a lot of functionality and template methods that are already set up for it in Xcode. Defining data models is trivial, you get tons of boilerplate code, and it's all optimized.
http://www.raywenderlich.com/934/core-data-on-ios-5-tutorial-getting-started
CoreData is sometimes described as having a steep learning curve. I disagree. If you're considering writing SQL yourself in your app, you're not going to have any trouble with CoreData.
The term "sandbox" is an abstract term for the portion of the device's filesystem that your application has read/write access to. The "Documents" directory is a specific directory within your application's sandbox. There are other files in your sandbox than just the documents directory, but most applications that save data to the filesystem in iOS do so in the documents directory.
you can open terminal and cd to /Users/Matt**/Library/Application Support/iPhone Simulator/5.1/Applications/5DB7A218-A0F6-485F-B366-91FD2F9BC062/Documents/
then sqlite3 tblStore.sqlite
then use .schema tblStore should show your table schema and you can see if it was built correctly.
Your database needs to be in the documents directory for write access. If your database was only going to be read, never written to it could be in your application bundle. One way to accomplishing this is to create your database.sqlite file and add it to the bundle and copy it to the documents directory (if it doesn't already exist there) on launch.
maybe you forgot Table Insertions. Created Database and Table but its empty table .
you trying to read the records from Table which is empty.
I tried the above didn't work for me, mainly because the example given would usually point to the DB file but not really create it.
Upon observing how sqlite3 works using the command shell, here is how I resolved the issue:
(For testing purposes), to create a file using the Linux shell, do:
sqlite3 Heider.db
This created a new database filename (Heider.db), also starts the DB command prompt to create SQL queries, ... before doing any query, just exist without doing anything by entering:
.exit
In the Linux shell check the file created, do an:
ls -ltra
You should see there is a "Heider.db" file created with 0 bytes in size, this means that the sqllite3 tool is creating a blank file with no contents.
Now, to check whether this will work, go back into sqlite:
sqlite3 Heider.db
Now this time, create a new table using:
create table test(id int not null primary key);
Insert some stuff:
insert into test(id) values (123);
Notice the query executes nicely without any errors.
Now, exit and check:
.exit
ls -ltra
The file should have some data in it, this confirms that the tool in Linux works at least...
Now, away from the Linux/Shell and back into XCODE/Development (or whatever tool you are developing with)... this makes our lives so easy as all we need to do is to create a file manually "somehow" using code instead, and then let sqlite use it.
Therefore, here is what you need to do:
// Check if the filename already exists:
DBFileName = #"MyNewFile.db";
if (![[NSFileManager defaultManager] fileExistsAtPath: DBFileName])
{
NSLog([NSString stringWithFormat:#"Database does not exists, creating: %#", DBFileName]);
[[NSFileManager defaultManager] createFileAtPath:DBFileName contents:NULL attributes:NULL];
}
// Use SQLite to access the new file to do whatever you want:
int DBOpen = sqlite3_open([_DBFileName UTF8String], &_SqlLite);
if (DBOpen == SQLITE_OK)
{
NSLog([NSString stringWithFormat: #"Client: SQLite DB Opended Successfully, creating test table..."]);
// Heider: Notice I am using "self" here because I am having this as a
wrapper class (see at the bottom of this post the whole function), you don't have to do the same, as you can use your own
SQLITE3 object directly instead...
[self ExecQuery:#"create table Test(id int not null primary key);"];
[self ExecQuery:#"insert into Test(id) values (123);"];
}
The SELF's ExecQuery I am using above is also below in case you need it:
-(BOOL)ExecQuery:(NSString *)Query {
BOOL Successful = NO;
if (sqlite3_prepare_v2(_SqlDB, [Query UTF8String], -1, &_SqlQuery, NULL) == SQLITE_OK)
{
if (sqlite3_step(_SqlQuery) == SQLITE_DONE)
{
NSLog([NSString stringWithFormat: #"Client: SQL Query Successful: %#", Query]);
} else {
NSLog([NSString stringWithFormat: #"Client-Error Executing SQL Query: %#", Query]);
}
} else {
Log(3, [NSString stringWithFormat: #"Client-Error Preparing SQL Query: %#", Query]);
}
sqlite3_finalize(_SqlQuery);
return Successful;
}
The process is to create a blank file anyhow you like, and then point sqlite3 to it and then do your SQL in the good old way... should be simple.
Good luck, I hope this helps.

So, I have been beating my head against the wall on this for about a week now.
I'm writing an iPhone app that has an sqlite database in it. I'm able to open the database and read from it (I put some test data in there through via the command line / terminal), select specific data, etc. But, what I cannot do is insert into the database from the phone. When I execute sqlite3_exec(...) it returns error code 8 "attempt to write a readonly database."
I had read other questions on here saying that I was using the Main Bundle's database and not the users database, and that the simulator will often times just "let you do it" while on a live device you'll get an error. Well, that's not what's happening in my case - I'm getting this error while running on the simulator. And from what I can tell my code to check the database is exactly as a lot of others recommend it to be.
Here is the code I use to verify the database exists, and if it doesn't I copy it:
// initialize db (if not already)
+(void) checkDatabase {
// setup some variables
Boolean success;
dbName = #"daarma.sqlite";
NSArray *documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDirectory, YES);
// I have tried this with both NSUserDirectory and NSUserDomainMask, desn't seem to make a difference
NSString *documentsDir = [documentPath objectAtIndex:0];
dbPath = [documentsDir stringByAppendingPathComponent:dbName];
// dbPath = [[NSBundle mainBundle] pathForResource:#"daarma" ofType:#"sqlite"];
// check to see if the database already exists
NSFileManager *fm = [NSFileManager defaultManager];
success = [fm fileExistsAtPath:dbPath];
if(success) {
NSLog(#"Database exists, returning.");
return;
}
// if not, we create it
NSLog(#"Creating database in user profile...");
NSString *dbPathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:dbName];
[fm copyItemAtPath:dbPathFromApp toPath:dbPath error:nil];
[fm release];
[documentPath release];
[documentsDir release];
}
When I go to insert data using this:
sqlite3 *db;
int open = sqlite3_open_v2([dbPath UTF8String], &db, -1, NULL);
if(open == 0) {
NSLog(#"open, inserting");
NSString *sql = [NSString stringWithFormat:#"insert into affiliates values('1','2','3','4','5','6','7','8','9','10','11','12')"];
int exec = sqlite3_exec(db, [sql UTF8String], NULL, NULL, NULL);
NSLog(#"exec = %d",exec);
}
sqlite3_close(db);
exec returns with the above mentioned error code 8: ""attempt to write a readonly database."
I've also tried the usual restarts, cleaning the project, resetting the simulator data. I even went in to my Simulator directory and deleted all the application data out manually. When I tried to go back in, it recognized the database wasn't there and copied it over, but I still get that error.
EDIT:
I've just noticed that if I do this in the checkDatabase method:
NSError *error;
[fm copyItemAtPath:dbPathFromApp toPath:dbPath error:&error];
NSLog(#"error = %#",error);
it causes the simulator to crash the first go around (after doing a content reset), but each time after that it resumes the above error with no crashes. So maybe I am doing something wrong with my checkDatabase method. ?? :( It never tells me the output of the error message.
try to change the open function to this
sqlite3_open_v2([dbPath UTF8String], &db, SQLITE_OPEN_READWRITE , NULL);
or basically use the trivial open function
Sqlite3_open([dbPath UTF8String],&db);// this should do the job
hope that helps :)
I tried your code, and it failed with open = 21 (SQLITE_MISUSE) in the following line:
int open = sqlite3_open_v2([dbPath UTF8String], &db, -1, NULL);
Because you pass -1 to flags parameter. It should be SQLITE_OPEN_READWRITE.
I have some more comments.
[fm release];
[documentPath release];
[documentsDir release];
These release's are not necessary, because you don't alloc/init, retain, or copy them.
NSString *sql = [NSString stringWithFormat:#"insert into affiliates values('1','2','3','4','5','6','7','8','9','10','11','12')"];
int exec = sqlite3_exec(db, [sql UTF8String], NULL, NULL, NULL);
You should use sqlite3_prepare_v2 and bind parameters instead of stringWithFormat: for SQL.
if(open == 0) { ... }
Whenever possible, you should use symbolic constant (SQLITE_OK) instead of magic number (0).
NSError *error;
[fm copyItemAtPath:dbPathFromApp toPath:dbPath error:&error];
NSLog(#"error = %#",error);
You should initialize error = nil before calling copyItemAtPath: because error is not changed when the copy operation succeeds.
i am trying to validate username and password entered by the user with the sqlite database.if the username and password are present in the database the user need not to log in.But if his username and password does not match he need to login. i have added the following code in my appdelegate first:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
databaseName =#"journeymapper.db3";
NSArray *documentsPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentsPaths objectAtIndex:0];
databasePath = [documentsDir stringByAppendingPathComponent:databaseName];
[self checkAndCreateDatabase];
}
-(void)checkAndCreateDatabase{
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
success = [fileManager fileExistsAtPath:databasePath];
if (success)
return;
NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath]stringByAppendingPathComponent:databaseName];
[fileManager copyItemAtPath:databasePathFromApp toPath:databasePath error:nil];
[fileManager release];
}
-(void)readLoginFromDatabase{
sqlite3 *database;
if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK){
const char *sqlStatement = "Select Username,Password from UserInformation";
sqlite3_stmt *compiledStatement;
if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK){
NSString *aUserName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)];
NSString *aPassword = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)];
}
sqlite3_finalize(compiledStatement);
}
sqlite3_close(database);
}
Initially i have checked if database is present .If not i have created one.Then i have read from database.
Then in my login controller's login action i have added the following code:
-(IBAction)login:(id)sender{
journey = (JourneyAppDelegate *)[[UIApplication sharedApplication]delegate];
if ([mUserName.text isEqualToString:#"shardulprabhu"] && [mPassword.text isEqualToString:#"password"]) {
[journey readLoginFromDatabase];
NSLog(#"journey read");
}
else{
[self signUp];
}
}
this code checks if myusername and password is equaltostring specified the one in database and if it is equal it should read from database.else it should signup.But when i run my app my app loads and when i enter username and password and click login button the app crashes.
i am having a warning on login action that JourneyAppDelegate may not respond to-readLoginFromDatabase
What may be the problem
thanks
At first, if it crashes, you need to post crash log here too.
Second thing - do not use sqllite for username / password storage. Do use keychain.
Third thing - if you do want to use sqllite to store something, why not via CoreData?
About your warning - it seems that you forgot to add your readLoginFromDatabase method to header file too.
If you want to remove the warning add this code to your JourneyAppDelegate.h
-(void)readLoginFromDatabase;
I've got the following iphone code, which seems to be failing:
sqlite3_stmt *dbps;
NSString *sql = #"delete from days where day=?1;insert into days(disabled,recipe_id,day) values(?2,?3,?1)";
int rc = sqlite3_prepare_v2(db, sql.UTF8String, -1, &dbps, NULL);
...
The 'rc' return code is 1, meaning SQLITE_ERROR (SQL error or missing database, according to the sqlite site). Not sure what i've done wrong? The database 'db' is indeed open, and other queries seem to work fine.
Thanks a lot guys
Remove the insert statement from your string. It is not compiled anyway since sqlite3_prepare_v2 will "only compile the first statement in zSql."
Perhaps you should use a trigger to do your (optional) delete, or use insert or replace.
Are you sure you have copied the database in Documents directory before opening it? iPhone OS only allow write permissions in documents directory. Here is the code for copying database to Documents directory -
//function to copy database in Documents dir.
-(void) checkAndCreateDatabase{
// Check if the SQL database has already been saved to the users phone, if not then copy it over
BOOL success;
// Create a FileManager object, we will use this to check the status
// of the database and to copy it over if required
NSFileManager *fileManager = [NSFileManager defaultManager];
// Check if the database has already been created in the users filesystem
success = [fileManager fileExistsAtPath:databasePath];
// If the database already exists then return without doing anything
if(success) return;
// If not then proceed to copy the database from the application to the users filesystem
// Get the path to the database in the application package
NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:databaseName];
// Copy the database from the package to the users filesystem
[fileManager copyItemAtPath:databasePathFromApp toPath:databasePath error:nil];
[fileManager release];
}
// open the database and fire the delete query...
sqlite3 *database;
NSString *sqlStatement = #"";
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [documentPaths objectAtIndex:0];
databasePath = [documentsDir stringByAppendingPathComponent:databaseName];
NSLog(#"%#",databasePath);
[serlf checkAndCreateDatabase];
if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK)
{
// here you can fire the delete query...
}
Silly me, i just had an old copy of the schema in my Documents folder, which didn't have the 'days' table in it. So i followed the instructions here: Cleaning up the iPhone simulator, and then it copied the new schema over, and it started working again.
Thanks for the help guys.
