Starting a CTE

  • I like the  next line when developing as well, since this makes it easy to add to the query and test things.

    I like the  next line when developing as well, since this makes it easy to add to the query and test things.

    Same here. I leave them on the next line in production though. If it makes things easier for development it makes sense that it makes it easier for maintenance also. :Whistling:

    Was helping somebody just yesterday on another site and they couldn't for the life of them figure out why their view was throwing a syntax error. The view started with a cte that had a leading semicolon. They claimed they had been wrestling the thing for a couple of days. I used Lynn's terminology that the semicolon is not a beginninator, but a terminator. And once they removed the semicolon their view was just fine. I don't know why the coding style of starting a cte became to be but it causes so much confusion.

    I know exactly the topic your talking about. And totally agree. i really dislike tutorials that teach the ;WITH syntax. It gives the completely wrong impression of what the semi colon is, and makes people think that it's called a ";with expression".

    A little harsh, but if Microsoft ever enforce the deprecation, I'm really looking forward to hearing people start asking why code like the following isn't working :hehe:
    SELECT 'a' AS a
    ;WITH CTE AS(
        SELECT 1 AS i)
    SELECT i
    FROM CTE
