Does 'GO' have to be on a new line? Because I tried to place it on the same line as the query and recieved an error

Because I know for a fact that is possible to have multiple statements within a single query, but Monitor does not like it right know and I need to figure out why, because Cache errors are as uninformative as it gets, so I am forced to ask here.

It's a one-time task and I can't be bothered to create new tables and procedures for it.

Then there would be 70 000 OR conditions.
