    This doesn't look like a Salesforce question, is it marketing cloud related?

Your query is failing because you are trying to store varchar data into a field which has Int/BigInt as a datatype. Do check your Data extension/ Table fields & their datatypes and the kind of values you wanted to store in those fields. Use functions like convert/format in your query to resolve the issue but do check the datatype first.

You can only do SELECT statements in SFMC.

While the engine is based on Microsoft Transact-SQL, not all functions are supported:


It doesn't list all that's possible.

And there are some differences between what's supported in Query Studio and Query Activities.
