We are having two MQTs (one of them is having large volume of data) . We are going to join these two MQTs on three fields and these fields are having datatype as varchar(30) in one MQT and in another as varchar(9). How much it will impact performance of queries if these fields have same column width means varchar(9) in both MQTs ? Please suggest ! We would need your suggestion here.
