Sqlite database file is getting encrypted or is not a database - iphone

Question

I have no idea what was the problem is in my program. When run this select code for fetching data from SQlite in my program, the first time it crashes with this error message:
kill error while killing target (killing anyway):
warning: error on line 2179 of "/SourceCache/gdb/gdb-1510/src/gdb/macosx/macosx-nat-inferior.c" in function "macosx_kill_inferior_safe": (os/kern) failure (0x5x)
quit
Here's my insert code:
-(id)init {
self = [super init];
sqlite3 *database;
NSMutableArray *locations;
NSString *result = nil;
NSString *dbPath = [self getWritableDBPath];
if(sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK)
{
NSString *sqlStr = [NSString stringWithFormat:#"select Longitude,Latitude from myLocation"];
const char *sqlStatement = [sqlStr UTF8String];
sqlite3_stmt *compiledStatement;
if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) {
locations = [NSMutableArray array];
while(sqlite3_step(compiledStatement) == SQLITE_ROW) {
double longitude = sqlite3_column_double(compiledStatement, 0);
double latitude = sqlite3_column_double(compiledStatement, 1);
NSLog(#"%f , %f",longitude,latitude);
NSString *coords = [[[NSString alloc] initWithFormat:#"%f,%f\n",longitude,latitude] autorelease];
[locations addObject:coords];
NSLog(#"this location :-%#",locations);
//[coords release];
}
result = [locations componentsJoinedByString:#","]; // same as `fake_location`
NSLog(#"this for resulte data :- %#",result);
// Get file path here
NSError *error;
if ( [result writeToFile:dbPath atomically:YES encoding:NSUTF8StringEncoding error:&error] ) {
NSLog(#"%#", [error localizedDescription]);
}
}
// Release the compiled statement from memory
sqlite3_finalize(compiledStatement);
}
sqlite3_close(database);
pointsArray = [[result componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] retain];
pointsArrayIndex = 0;
oldLocationsIndex = 0;
[result release];
oldLocations = [[NSMutableArray alloc] init];
return self;
}
The second time I run my application, it shows me that on the console:
Save Error: file is encrypted or is not a database
What do these errors mean, and how do I solve that?

Answer 1

You need to fire insert query using following:
-(void)insertLocation:(double)latitude withLongitude:(double)longitude
{
sqlite3_stmt *insertStatement = nil;
const char *sql = "insert into UserJourneyLocation(Latitude, Longitude) Values(?,?)";
int returnValue = sqlite3_prepare_v2(database, sql, -1, &insertStatement, NULL);
if(returnValue == SQLITE_OK)
{
sqlite3_bind_double(insertStatement,1,latitude);
sqlite3_bind_double(insertStatement,2,longitude);
if(sqlite3_step(insertStatement)==SQLITE_DONE)
{
//Data;
}
}
sqlite3_finalize(insertStatement);
}

Answer 2

Yes I have.
Go to iphone application document folder
/users/(yourname)/library/application support/iphone simulator/user/application
And remove all Targets.After that Restart your application.
