Hello, I'm trying to add limit / offset support to Sybase (v11) dialect. Unfortunately sybase syntax is not standard [1] (before v12 at least) compared to other dialects.
Example ```sql select * from table LIMIT 10 OFFSET 5 -- standard SQL select TOP 10 START AT 5 * from table -- Sybase ``` SqlSelectOperator [2] has unparsing of LIMIT / OFFSET at the end. Which makes it difficult to inject custom SqlNode(s). What is the recommended way to deal with this? 1) Custom SqlSelectOperator for Sybase 2) Splitting SqlSelectOperator.unparse() to be more customizable 3) Adding special SqlNode(s) to SqlSelect.selectList 4) Adding special SqlNode(s) to SqlSelect.keywordList Thanks, Andrei.
