Question

I am using the following code to open database in SQLite and execute an insert query.

// Open the database and store the handle as a data member
if (sqlite3_open([databaseFile UTF8String], &databaseHandle) == SQLITE_OK)
{

    const char *sqlStatement = [insertStmt cStringUsingEncoding:NSUTF8StringEncoding];
    char *error;

    if (sqlite3_exec(databaseHandle, sqlStatement, NULL, NULL, &error) == SQLITE_OK)
    {
        NSLog(@"Config table values inserted.");
        registration_done = YES;
    } 
    else 
    {
        NSLog(@"Error: %s", error);
        [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:1]]; 

        if (sqlite3_exec(databaseHandle, sqlStatement, NULL, NULL, &error) == SQLITE_OK) {
            NSLog(@"Config table values inserted 2.");
            registration_done = YES;
        } 
        else {
            NSLog(@"Error: %s", error);
        }
    }
}
else{

    sqlite3_close(databaseHandle);
}

sqlite3_close(databaseHandle);

But I am getting following error and the app is terminating after that:

-[__NSCFType UTF8String]: unrecognized selector sent to instance 0x15d9a0

Database files and tables are created in the /Caches/ directory as I am using Phonegap(2.1.0). Phonegap is properly executing query prior to above Objective-C code being called, which means that tables are getting created successfully in the /Caches/ directory.

Just use

const char *sqlStatement = [insertStmt UTF8String];
