Our project uses EJB3 with OpenJPA 2.4.3 and TOMEE plume 7.1.0
We have a custom /DBDictionary /that requires the Column data passed to
this method:
- public void setUnknown(PreparedStatement stmt, int idx, Object
val,*Column col)* throws SQLException {
When a prepared statement is executed, the logic
in//org.apache.openjpa.jdbc.kernel.PreparedSQLStoreQuery.java calls
DBDictionary.setUnknown with a hard-coded NULL value for Column parameter.
//
We have an older version of
org.apache.openjpa_1.3.0.0_1-1-1-SNAPSHOT.jar packaged in Weblogic and
the DBDictionary setUnknown works correctly. Column data is passed in
correctly.
To get around this issue, we tried the following change and the rest of
our logic works as expected. Please advise if this change is correct or
if you suspect any other issues with this code.
ResultObjectProvider rop;
PreparedStatement stmnt = null;
try {
stmnt = !range.lrs ? buf.prepareStatement(conn) :
buf.prepareStatement(conn, fetch, -1, -1);
int index = 0;
SelectImpl cachedSelect = pq.getSelect();
SQLBuffer sqlBuffer = cachedSelect.getSQL(); List columns =
sqlBuffer.getColumns(); for (int i = 0; i < params.length; i++) {
*/if(columns != null && columns.size()>i)
{/**//**/dict.setUnknown(stmnt, ++index, params[i],
(org.apache.openjpa.jdbc.schema.Column) columns.get(i));/**//**/} else
{/**//**/dict.setUnknown(stmnt, ++index, params[i], null);/**//**/}/*
}
dict.setTimeouts(stmnt, fetch, false);
ResultSet rs = stmnt.executeQuery();
Result res = cachedSelect.getEagerResult(conn, stmnt, rs,
store, fetch, false, null);
Your help is greatly appreciated
Thanks
