Hello,
I would like use clause LIKE in my EJB-QL query. Like this: . But it doesn�t works. Reading other posts and forums, I perceived that it is not possible use LIKE with parameter, only with constants.
So I tried other alternative. I wrote my query this: . It works!
Now, I want your opinion. Is this a acceptable alternative? Or is this a ugly patch?
Thanks,

I have a...
<finder>
<name>findByStartsWithAndLocale</name>
<query>entry LIKE "{0}%" AND locale = {1}</query>
<order></order>
</finder>
block in my JAWS.xml. It works fine. Maybe it was the surrounding characters of your arg.
Good luck.

Matthew:
I've never saw a query like yours. From I read We use "?1" for parameters not "{0}". Is this a Extension to EJB-QL of JBoss?
Thanks,

I'm using now JBoss 4.2.3.GA and that SUBSTRING doesn't seem to work for this purpose anymore.

But I tried this and it worked for me:


This simulates the query:


You can even do a CONCAT(CONCAT('%', ?1), '%') if you need something like '%?1%' instead.
 
Don't get me started about those stupid light bulbs.
