Problem Statement:

One of the view creation scripts in our deployment failed continuously with the below exception:

Invalid parameter 1 specified for datediff.
Incorrect syntax near the keyword ‘AS’.

The root cause of this error is as below.

FLOOR((DATEDIFF("W",ml.column1,ML.column2)+1)/7) AS aliasname

Solution:

FLOOR((DATEDIFF(W,ml.column1,ML.column2)+1)/7) AS aliasname

The change is that the datepart has been modified to remove the double quote.
