What is the Null Character literal in TSQL?

Question

I am wondering what the literal for a Null character (e.g. \'\\0\') is in TSQL.

Note: not a NULL field value, but the null character (see link).

Answer 1

I was having the same issue and using nullif solved it for me.

Select nullif(field_with_nullchar,'') from FOO where BAR = 20
