> Hi
> I want to use general hints below. I observed i was able to put my sourcehint as below which yields generalhint information to data_window procedure. As per this document https://docs.jboss.org/author/display/TEIID/Query+Plans if i use KEEP_ALIASES general hint is available for all nested queries but i was not able to get it working
> SELECT /*+ sh[KEEP ALIASES]:'foo' bar:'leading' */ \r\n" when i use something like this general hint is null in all the executions.
> If i use below general hint is available only to the first execution.
> "SELECT /*+ sh:'foo' bar:'leading' */ \r\n"
> + " chorus_results.* \r\n"
> + "FROM (\r\n"
> + " EXEC data_window('select pkey, counter from testing.bigtable WHERE pkey=? LIMIT 300', ?)\r\n"
> + ") AS chorus_data_window, ARRAYTABLE(chorus_data_window.tuple COLUMNS pkey long, counter long) AS chorus_results LIMIT 0, 20",
