Hello all

in my mapping file i have the following discriminator formula:

Code:
<discriminator
         type="java.lang.Integer"
         formula=" CASE ( SELECT TAGB.INUTZERGRUPPE FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)
                  WHEN 1 THEN 1
                  WHEN 2 AND (SELECT TAGB.FK_TAART_ILAUFNR FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=1 THEN 2
                  WHEN 2 AND (SELECT TAGB.FK_TAART_ILAUFNR FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=2 THEN 21
                  ELSE 0
                  END "/>



Unfortunatley it's not working. I always get an oracle error:

Code:
Caused by: java.sql.SQLException: ORA-00905: Missing kexword

   at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:145)


I'm using hibernate 3.1 and Oracle 10g Express Edition. Is it possible that my oracle version doesn't support the CASE??

Any help appreciated! Regards...
Angela

SOLUTION:

Code:
        <discriminator
         type="java.lang.Integer"
         formula=" CASE 
                  WHEN (SELECT TAGB.INUTZERGRUPPE FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=1 THEN 1
                  WHEN (SELECT TAGB.INUTZERGRUPPE FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=2 AND (SELECT TAGB.FK_TAART_ILAUFNR FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=1 THEN 2
                  WHEN (SELECT TAGB.INUTZERGRUPPE FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=2 AND (SELECT TAGB.FK_TAART_ILAUFNR FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=2 THEN 21
                  WHEN (SELECT TAGB.INUTZERGRUPPE FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=3 THEN 3
                  WHEN (SELECT TAGB.INUTZERGRUPPE FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=4 AND (SELECT TAGB.FK_TAART_ILAUFNR FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=3 THEN 4
                  WHEN (SELECT TAGB.INUTZERGRUPPE FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=4 AND (SELECT TAGB.FK_TAART_ILAUFNR FROM TANGEBOT TAGB WHERE FK_TANGE_ILAUFNR=TAGB.ILAUFNUMMER)=4 THEN 41
                  ELSE 0
                  END "/>
