I use the following code to make a rule and use it for my PHONE column:
CREATE RULE phone_rule AS
@phone LIKE '([0-9][0-9][0-9]) [0-9][0-9][0-9]-[0-9][0-9][0-9][0-9]'
The problem is :
When I run this code nothing add to my "Data Type" drop down box to set my PHONE column data type to my created rule (phone_rule).
What is the solution?
