SQL conversion from varchar to uniqueidentifier fails in view

Question

I\'m stuck on the following scenario. I have a database with a table with customer data and a table where I put records for monitoring what is happening on our B2B site.

Answer 1

Use

TRY_CONVERT(UNIQUEIDENTIFIER, parameter2) AS customerguid

instead of

 CONVERT(UNIQUEIDENTIFIER, parameter2) AS customerguid

Views are inlined into the query and the CONVERT can run before the WHERE.
