When I work with CTE, I get this error when I dont give smicolon, so it was easy to answer 🙂

Thanks for the question

I think the explanation need some work.

CTEs doesn't ALWAYS need a semi-colon in front.

This for example works fine:

DECLARE @tmpVariable INT

WITH cte

AS

(

SELECT 1/0 as 'Result'

)

SELECT *

FROM cte

I'd like to know when a CTE needs semi-colon and not... I always though its only after a select from a table, but apparently not 🙂

In the local help it says "When a CTE is used in a statement that is part of a batch, the statement before it must be followed by a semicolon."

but the linked article states this

I know that is not a requirement to terminate every SQL Statement, but it does make it easier to read. However in most cases, other than readability the termination of the previous statement really doesn’t matter. . . In most cases.

I never really tested this much, but in general I just follow the statement highlighted in bold.

Thanks for the question.

I'm actually surprised so many people have got this wrong.

I say that because when I started using CTEs I was not accostumed to using the semicolon so I would ALWAYS get this error. I'm sure it happened to a lot of other folks when learning this feature.
