how to insert values in sqlite - iphone

Question

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSString *dbPath =[documentsDir stringByAppendingPathComponent:#"register.sqlite"];
BOOL success = [fileManager fileExistsAtPath:dbPath];
sqlite3_stmt *selectstmt;
if(!success)
{
NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"register.sqlite"];
success = [fileManager copyItemAtPath:defaultDBPath toPath:dbPath error:&error];
if (!success)
NSAssert1(0, #"Failed to create writable database file with message '%#'.", [error localizedDescription]);
}
if (sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) {
sql = "select lastname,email,firstname from reg_FORM";
if(sqlite3_prepare_v2(database, sql, -1, &selectstmt, NULL) == SQLITE_OK) {
while(sqlite3_step(selectstmt) == SQLITE_ROW) {
lastname = [NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 0)];
email=[NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 1)];
firstname=[NSString stringWithUTF8String:(char *)sqlite3_column_text(selectstmt, 2)];
NSLog(#"----%#",lastname);
NSLog(#"----%#",email);
NSLog(#"----%#",firstname);
}
sqlite3_finalize(selectstmt);
}
sqlite3_close(database);
}
I am using this code to retrieve the values in db, but I did know how to insert data in db. I am trying this below code but it does not work
const char *sql = "insert into reg_FORM (firstname,lastname,email,company,phone) VALUES (aaa,aaa,aaa,aaaa,1223)";
sqlite3_exec(database, [[NSString stringWithFormat:#"insert into reg_FORM (firstname,lastname,email,company,phone) VALUES (aaa,aaa,aaa,aaaa,1223)"] UTF8String], NULL, NULL, NULL);
//give code for insert values in db

{
BOOL returnValue = YES;
sqlite3_stmt *insertStmt = nil;
sqlite3 *UserDB ;
if (sqlite3_config(SQLITE_CONFIG_SERIALIZED) == SQLITE_OK)
{
NSLog(#"Can now use sqlite on multiple threads, using the same connection");
}
int ret = sqlite3_enable_shared_cache(1);
if(ret != SQLITE_OK)
{
}
// Open the database. The database was prepared outside the application.
if (sqlite3_open([app.dataBasePath UTF8String], &UserDB) == SQLITE_OK)
{
if(insertStmt == nil)
{
NSString *strValue = [NSString stringWithFormat:#"insert into languagemaster Values(?,?)"];
const char *sql = [strValue UTF8String];
if(sqlite3_prepare_v2(UserDB, sql, -1, &insertStmt, NULL) != SQLITE_OK)
{
NSLog(#"Error while creating insertStmt in tblUserAccount %#", [NSString stringWithUTF8String:(char *)sqlite3_errmsg(UserDB)]);
returnValue = NO;
}
}
if(sqlite3_bind_int(insertStmt, 1, langid) ) // langid is int
{
return NO;
}
if(sqlite3_bind_text(insertStmt, 2, [strLanguageName UTF8String], -1, SQLITE_TRANSIENT) != SQLITE_OK) // strLanguageName is string
{
return NO;
}
if(SQLITE_DONE != sqlite3_step(insertStmt))
{
NSLog(#"Error while Executing insertStmt in tblLocation %#", [NSString stringWithUTF8String:(char *)sqlite3_errmsg(UserDB)]);
returnValue = NO;
}
sqlite3_reset(insertStmt);
if (insertStmt)
{
sqlite3_finalize(insertStmt);
insertStmt = nil;
}
}
sqlite3_close(UserDB);
return returnValue;
}
