Question

I have created one application, where I am storing the data into database and reading it. I have created a .sql file and added it into the resource folder. I can save and retrive the data over the simulator, my app is working fine over simulator but when I install the same app over device I am getting error as “no such table”.

Can anyone provide solution over this issue.

Here is the block of code that i m using:

/////// Inside AppDelegate.m >>Start>>>

///// to check the database exist or not >>>>

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;

NSString *dbPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"TempDatabase.sql"];
BOOL success = [fileManager fileExistsAtPath:dbPath]; 

if(!success) {

    NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"TempDatabase.sql"];
    success = [fileManager copyItemAtPath:defaultDBPath toPath:dbPath error:&error];


    if (!success) 

        NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);  

} else {

    NSLog(@"Database file found at path %@", dbPath);

}

/////// Inside AppDelegate.m <<

/////// Logic to write files in database >>> start>>

           sqlite3 *pDb; 
    char *databaseName; 

    databaseName = @"TempDatabase.sql";

    NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDir = [documentPaths objectAtIndex:0];
    //databasePath = [documentsDir stringByAppendingPathComponent:databaseName];

    databasePath =[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"TempDatabase.sql"];

    //[self copyDatabaseIfNeeded];


    if(sqlite3_open([databasePath UTF8String], &pDb) == SQLITE_OK) 
    {

        const char *sqlStatement = "INSERT INTO tablename (name) VALUES(?)";

        sqlite3_stmt *compiledStatement;
        if(sqlite3_prepare_v2(pDb, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) 
        {


             sqlite3_bind_text( compiledStatement, 1, [strTxtFldValue UTF8String], -1, SQLITE_TRANSIENT);
        }
        if(sqlite3_step(compiledStatement) != SQLITE_DONE ) 
        {
             NSLog( @"~~~~~~~~~~~ 1 Error: %s", sqlite3_errmsg(pDb) );
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Name name is not added." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [alert show];
            [alert release];

        } else {

            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Confirmation" message:@"name is added successfully." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [alert show];
            [alert release];

                }
        sqlite3_finalize(compiledStatement);
    }

    sqlite3_close(pDb);

Answer 1

Have you tried by creating database at runtime. Execute the query at runtime and create the table, try this out this will definitely help you out.
