Criteria with Like using Oracle

Hi!

 

I'm using Torque with Oracle9i and it works fine.

 

But now I have a problem with a select statement.

We have a node table that has a key, for instance:

*	\ (for root)
*	\\Folder1 <file:///\\Folder1> 
*	\\Folder1\Folder2 <file:///\\Folder1\Folder2> 

 

If I use the code in the end of this mail the query works fine for a search
from the root, that is "key like '\\%'.

But when the node key value is '\\Folder1\%' the like statement is not
generated, instead it becomes key='\Folder1\'

 

Does anyone have a clue what's going on?

 

The Code:

 

Criteria criteria = new Criteria();

criteria.add(NodePeer.LEVEL,node.getLevel() + 1);

String nodeKey = node.getKey() + "\\" + "%";

criteria.add(NodePeer.KEY, (Object)nodeKey, Criteria.LIKE);

criteria.addAscendingOrderByColumn(NodePeer.NAME);

List list = NodePeer.doSelect(criteria,connection);

 

Thanks in advance!

 

Best Regards

PS It works fine if I use / instead of \ DS

Hi!

Yes, in java I use '\\'.

So for '\\%' from java using LIKE it works fine, but with '\\\\Folder1\\%'
in java Torque transform it to EQUAL to '\\Folder\\'

Could it have something to do with that we have '\\\\Folder'?

Like I said, it works with '/'.
That is, '//%' and '////Folder1//%' both using LIKE.

Best Regards
