    • processSql

      public String processSql(String sql, org.hibernate.query.spi.Limit limit)
      When the offset of the current row is 0, add a top(?) clause to the given SQL query. When the offset is non-zero, wrap the given query in an outer query that limits the results using the row_number() window function. 
       with query_ as (
     select row_.*, row_number()
         over (order by current_timestamp) AS rownumber_
     from ( [original-query] ) row_
 )
 select [alias-list] from query_
 where rownumber_ >= ? and rownumber_ < ?

      Where [original-query] is the original SQL query, with a top() clause added iff the query has an order by clause, and with generated aliases added to any elements of the projection list that don't already have aliases, and [alias-list] is a list of aliases in the projection list.
