Question

I am using sqlite database for iphone app. but its crash on “while loop” line while retrieving data from database sometimes.

-(void)GetMethod
{

    NSString *query = [[NSString alloc] initWithFormat:@"SELECT * FROM errorlogs"];
    sqlite3_stmt *statement;    
    if (sqlite3_prepare_v2(database, [query UTF8String],-1, &statement, nil) == SQLITE_OK) 
    {
        while (sqlite3_step(statement) == SQLITE_ROW) **// EXC_BAD_ACCESS ON THIS LINE**
        { 
            char *uid1 = (char *)sqlite3_column_text(statement, 0);
            NSString *uid = [NSString stringWithFormat:@"%s",uid1];
        }
    }
    sqlite3_finalize(statement);
}

why I am getting this EXC_BAD_ACCESS on while loop.

Thanks.

Answer 1

Either sqlite3_step(statement) or SQLITE_ROW is not initialized, or has already been released. When it runs the equality check on the nonexistent object, it throws EXE_BAD_ACCESS.

Are you returning any rows?
