I have a very simple question regarding creating columns in a table   Can we create a column in a table in such a way that it will allow only certain length, nothing less or nothing more   here is an example     create table test(column1 char(2));   will create table with column1 which will accept characters upto length two. I want the column to accept the column value which is absolutely length of two.     Any Help appreciated   Thank you Vinay
