hi,

i have a field named 'nim', in my table which is a char(10) field.

i want to create a constraint that checks the field so the field must be 10 characters long and each character is a number.

i can only think of nim like '[0-9][0-9][0-9] .... [0-9]' . i can't use isnumeric() because it may still accept dot character right? anyway i've tried to use the isnumeric function but i get this " error Incorrect syntax near ')' ".

i don't know what's wrong with this line

Expand|Select|Wrap|Line Numbers

1. CONSTRAINT checkNIM CHECK ( len(nim)=10 and isnumeric(nim) )

thank you very much.

IsNumeric() is a function.

Try

Expand|Select|Wrap|Line Numbers

1. isnumeric(nim) = 1
