Actually, i have a need to store the numbers like "AS2303",
TS3381"(first 2 alphabets,next 3 numbers). What i want is, i have to
assign the integrity which can check the following values,
23334, ASDER, SDE23, 233A4 and like this.
If i assign as a character type domain.Then i can't check the above
cases.
Can anyone help me?
