Reb .. sorry another silly questions... if I have to write an insert statement where by one of the values can be only one of a list given (i.e. can't be any varchar) how do I write that statement...
e.g normal insert statement
INSERT INTO table X (one,two,three)
VALUES (1,2,3)
but what if column 3 can be only one of a chosen list and no other values are allowed very similar to boolean you can only choose Yes or No ... but in this case a value for column three can be only one of the set {AA, BB, AB, ABC} ... hence if somone wanted to insert ACB they wont be allowed to and there would be an error .... hope I explained this right !!!
