I have a column setup using the Int datatype and a length of 4. First: does this mean that the allowable range is from -9999 to 9999? Second: I can't seem to change the 4 to anything else, how can I modify the length
no, the 4 indicates the amount of bytes used. It's a fixed size, you can't change it. As specified by BOL, integer values '(...)from -2^63 (-9,223,372,036,854,775,808) through 2^63-1 (9,223,372,036,854,775,807).'. If this won't do use a bigint instead.
EDIT: Brett, I'll quote you on this: Damn...sniped again
