with inner
gropu by having order etc.

but i have problems with query who have transact sql (t-sql)

My eg. query like :

@declare variable 1
@declare var2

sel;ect * from where a = @var2

Solved : Sql.newInstance(url, “com.microsoft.sqlserver.jdbc.SQLServerDriver”)
and import library is - > import groovy.sql.Sql
