Fmdb Select Query With Variable Table Name

I want to get results from different tables, tables are selected by the user. So, I am using table name as variable but it returns nil query. FMResultSet *query = [db1 execute

Solution 1:

Use this Code :

FMResultSet *query = [db1 executeQuery:[NSString stringWithFormat:@"SELECT Image, Explanation FROM %@ WHERE Image !='empty'"
"UNION SELECT Image, Explanation FROM %@ WHERE Image !='empty'"
"UNION SELECT Image, Explanation FROM %@ WHERE Image !='empty'"
"UNION SELECT Image, Explanation FROM %@ WHERE Image !='empty'"
"UNION SELECT Image, Explanation FROM %@ WHERE Image !='empty'"
"UNION SELECT Image, Explanation FROM %@ WHERE Image !='empty'", [NSString stringWithFormat:@"%@1",tableName], [NSString stringWithFormat:@"%@2",tableName],
[NSString stringWithFormat:@"%@3",tableName], [NSString stringWithFormat:@"%@4",tableName], [NSString stringWithFormat:@"%@5",tableName], [NSString stringWithFormat:@"%@6",tableName]]];
