Dapper. Execute Query with GOs

GO is not a SQL statement it is merely a batch separator, in fact you could rename it to whatever you want.

The way Management Studio figures this out is by parsing the SQL. It is easy to write a trivial parser that can chunk the statements up. Just split the string on "GO" and send each statement to Dapper.

However, to be 100% correct you need a sophisticated parser.

select '
GO ' GO from [GO] 

Dapper cannot help you here. Instead, I would suggest you try SQL Server Management Objects to execute large SQL commands like the one you mentioned. And it does supports GO statements.
