Good morning, With ibatis, do overlap checking:
(1) select (DATE #begin_date#, DATE #end_date#) overlaps (DATE '2008-01-01', DATE '2009-01-01') . #begin_date# is varchar . #end_date# is varchar Always get: ============ Cause: java.sql.SQLException: ERROR: syntax error at or near "$4" However, when I updated the query to (2) select (#begin_date#::DATE, #end_date#::DATE) overlaps (DATE '2008-01-01', DATE '2009-01-01') It works. I am bit confused why (1) does not work, but (2) does? -- Lu Ying -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
