Looks like a Cayenne bug to me... t2 is nowhere to be found in the
translated query. besides a join to manufacturer should probably be an
OUTER JOIN. Would you mind opening a bug report please?

I am running into an error that I think might be a bug in the EJBQL
implementation unless I'm doing something wrong that I'm not
seeing. I
am running the following EJBQL query against a MySQL 5.0 database with
Cayenne 3.0M3, it looks valid to me:
SELECT COUNT(p) from Product p where p.vsCatalog.id = 1 and
(
p.displayName like '%rimadyl%'
or p.manufacturer.name like '%rimadyl%'
or p.description like '%rimadyl%'
or p.longdescription like '%rimadyl%'
or p.longdescription2 like '%rimadyl%'
or p.manufacturerPartNumber like '%rimadyl%'
or p.partNumber like '%rimadyl%'
)
The error log shows that the SQL it produced is:
SELECT COUNT(*) AS sc0 FROM product t0 INNER JOIN
catalogmanager.vs_catalog t1 ON (t0.vs_catalog_id = t1.id) INNER JOIN
manufacturer t3 ON (t0.manufacturer_id = t3.id) WHERE t2.id = ? AND
t0.display_name LIKE ? OR t3.name LIKE ? OR t0.description LIKE ? OR
t0.longdescription LIKE ? OR t0.longdescription2 LIKE ? OR
t0.mfg_partnum LIKE ? OR t0.partnum LIKE ?
And the SQLException:

Three objects are involved, Catalog, Product, and Manufacturer. I can
provide the source code and the .map.xml file if necessary. The query
was working in this form before I had to add the AND and the
parentheses
around all of the OR'ed conditions:
SELECT COUNT(p) from Product p where
p.displayName like '%rimadyl%'
or p.manufacturer.name like '%rimadyl%'
or p.description like '%rimadyl%'
or p.longdescription like '%rimadyl%'
or p.longdescription2 like '%rimadyl%'
or p.manufacturerPartNumber like '%rimadyl%'
or p.partNumber like '%rimadyl%'
Any ideas? Thanks.
