Answer 1

Real answer was behind the question, so I'm sorry.
Groovy SQL makes parameterized query from GString, so after I had defined GString

def sql = "select * from ${it}_1";

I passed it to Groovy SQL and when I tried to execute the query, the actual query was

"select * from :?_1";

Of cource this drives MSSQL crazy.
Thanks to you all again, maybe someone will find this useful.
