[eclipselink-dev] Re: [eclipselink-users] Problem with Multipletables in eclispelink.
|
Hi Development team,
I am able to resolve the following
problem by commenting the following part of the
initializeMultipleTablePrimaryKeyFields method in ClassDescriptor file
of eclipselink source code. Could you please let me know
why the following portion is giving the problem by generating
unnecessary joins to the generated query.. You can find the runtime
xmls and table creation scripts in the previous mail to user
group. Please let me know commenting the following code
will give any problems..
/*else {
// If the user has specified a custom multiple table join then we do
not assume that the secondary tables have identically named pk as the
primary table.
// No additional fk info was specified so assume the pk field(s) are
the named the same in the additional table.
Map newKeyMapping = new HashMap(getPrimaryKeyFields().size() + 1);
getAdditionalTablePrimaryKeyFields().put(table, newKeyMapping);
// For each primary key field in the primary table, add a pk
relationship from the primary table's pk field to the assumed
identically named secondary pk field.
List primaryKeyFields = getPrimaryKeyFields();
for (int pkIndex = 0; pkIndex < primaryKeyFields.size(); pkIndex++) {
DatabaseField primaryKeyField =
(DatabaseField)primaryKeyFields.get(pkIndex);
DatabaseField secondaryKeyField =
(DatabaseField)primaryKeyField.clone();
secondaryKeyField.setTable(table);
newKeyMapping.put(primaryKeyField, secondaryKeyField);
// Must add this field to read, so translations work on database row.
getFields().addElement(secondaryKeyField);
if (!getQueryManager().hasCustomMultipleTableJoinExpression()) {
_expression_ keyJoinExpression =
builder.getField(secondaryKeyField).equal(builder.getField(primaryKeyField));
joinExpression = keyJoinExpression.and(joinExpression);
getQueryManager().getTablesJoinExpressions().put(table,
keyJoinExpression);
if(isChild) {
getInheritancePolicy().addChildTableJoinExpressionToAllParents(table,
keyJoinExpression);
}
}
}
}*/

I am trying to migrate sample application from toplink to eclipselink.. I
am able to migration most of them successfully.. But When view having
references to multiple tables, iam facing problem with invalid identifier
problem.. I am attaching the runtime xml and table creation scripts which

Please help me to resolve this problem.
