Is the LIKE operator case-sensitive with MSSQL Server?

Question

In the documentation about the LIKE operator, nothing is told about the case-sensitivity of it. Is it? How to enable/disable it?

I am querying varchar(n)

Answer 1

All this talk about collation seem a bit over-complicated. Why not just use something like:

IF UPPER(@@VERSION) NOT LIKE '%AZURE%'

Then your check is case insensitive whatever the collation
