Interacting with a database involves executing queries. FMDBHelpers simplifies this process:


[queue inDatabase:^(FMDatabase *database) {
    NSString *query = @"SELECT * FROM my_table";
    FMResultSet *resultSet = [database executeQuery:query];
    while ([resultSet next]) {
        // Get results here
    }
}];

4. Transactions

Working with transactions ensures data integrity. FMDBHelpers allows you to easily manage transactions:


[queue inTransaction:^(FMDatabase *database, BOOL *rollback) {
    // Perform transactional operations
    if (someErrorOccurred) {
        *rollback = YES;
    }
}];
