EJBQL collection binding
------------------------
Key: CAY-1121
URL: https://issues.apache.org/cayenne/browse/CAY-1121
Project: Cayenne
Issue Type: Bug
Components: Cayenne Core Library
Affects Versions: 3.0
Reporter: Andrus Adamchik
Assignee: Andrus Adamchik
Fix For: 3.0
When binding collections as EJBQL variable, Cayenne erroneously binds each
collection value as VARBINARY at the JDBC level. This works ok on some DB's
(hiding the problem) but breaks on some others. E.g. on SQLServer:
List<Integer> id = ...
String ejbql = "delete from MeaningfulPKTest1 m WHERE m.pkAttribute in
(:id)";
EJBQLQuery query = new EJBQLQuery(ejbql);
query.setParameter("id", id);
Results in the following error:
INFO: *** error.
com.microsoft.sqlserver.jdbc.SQLServerException: The conversion from INTEGER to
VARBINARY is unsupported.
