Hi there,

I made the following query, but I have:

msg 156, level 15, state 1, line 2
incorrect syntax near the keyword "case"

USE my_database
CASE WHEN Column_E < Column_D THEN 0
ALTER TABLE my_table
ADD Column_Z AS (DATEDIFF(DAY, Column_A, Column_E))

How can I solve the problem?

Thanks

[code]
USE my_database
ALTER TABLE my_table
ADD Column_Z AS (CASE WHEN Column_E < Column_D THEN 0 ELSE DATEDIFF(DAY, Column_A, Column_E) END)
[/code]
