SQLTemplate improvement: new #bindColumnsEqual #bindColumnsNotEqual directives
------------------------------------------------------------------------------
Key: CAY-805
URL: https://issues.apache.org/cayenne/browse/CAY-805
Project: Cayenne
Issue Type: Improvement
Components: Cayenne Core Library
Affects Versions: 3.0
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Priority: Minor
Fix For: 3.0
To support matching against ObjectId's or Persistent objects with compound PKs,
we need two new directives: #bindColumnsEqual #bindColumnsNotEqual. The syntax
would follow that of #bindEqual, with one extra "columns" parameter; and all
remaining parameters being arrays or collections:
#bindColumnsEqual(columns values jdbcTypes precisions)
The motivation for this addition is actually EJBQL support for similar
functionality , but it should be generally useful as well.
