[Hibernate-JIRA] Created: (HHH-3119) LazyInitializationException from 3.2.4+ onward
by Nick de Graeve (JIRA)
LazyInitializationException from 3.2.4+ onward
----------------------------------------------
Key: HHH-3119
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3119
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6, 3.2.5, 3.2.4.sp1, 3.2.4
Reporter: Nick de Graeve
Priority: Blocker
We used to run JBoss 4.0.4.GA and we included Hibernate 3.2.0CR2 ourselves. Now we migrated to JBoss 4.2.2.GA and in that one Hibernate 3.2.4.sp1 is included by default.
Unfortunately, we're getting LazyInitializationException when the object graph is more than 2 levels deep.
E.g. RtTask --[OK]--> Priority --[FAIL]--> DictionaryEntry
We haven't changed anything to our beans or configuration files.
I did find out that v.3.2.4 is the first version that throws the exception.

[Hibernate-JIRA] Commented: (HHH-1759) ClasscQueryTranslator do not make SQL Function substitution
by Sandeep Vaid (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1759?page=c... ]
Sandeep Vaid commented on HHH-1759:
-----------------------------------
Steve, yes i am using weblogic 8 and hence forced to use ClassicQueryTranslatorFactory.
and if i elaborate more on this problem, i get different different error messages in the following 2 cases :
CASE 1: I have extended the DB2Dialect and defined my own function:
registerFunction("svminus1", new SQLFunctionTemplate( Hibernate.TIME, "current time") );
HQL: select svminus1() from Temp c where c.id=1
SQL: select svminus1() as col_0_0_ from TEMP c where c.id=1
The error message is :
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0440N No authorized routine named "SVMINUS1" of type "FUNCTION"
having compatible arguments was found. SQLSTATE=42884
NOTE: In this case, while converting HQL to SQL it has not replaced my custom function name by it's definition.
CASE 2:
registerFunction("svminus1", new NoArgSQLFunction("current time", Hibernate.TIME, false) );
This time the error is :
org.hibernate.QueryException: aggregate function expected before ( in SELECT [select svminus1() from Temp c where c.id=1]

[Hibernate-JIRA] Created: (HHH-3956) ClassicQueryTranslatorFactory & Custom Functions Doesn't work?
by Sandeep Vaid (JIRA)
ClassicQueryTranslatorFactory & Custom Functions Doesn't work?
--------------------------------------------------------------
Key: HHH-3956
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3956
Project: Hibernate Core
Issue Type: Bug
Affects Versions: 3.3.1
Reporter: Sandeep Vaid
I am using hibernate 3.2.1-ga version.
I have extended the DB2Dialect and defined my own function:
registerFunction("svminus1", new SQLFunctionTemplate( Hibernate.TIME, "current time") );
It is working fine with ASTQueryTranslatorFactory
HQL: select svminus1() from Temp c where c.id=1
SQL: select current time as col_0_0_ from TEMP c0_ where c0_.ID=1
But when i use ClassicQueryTranslatorFactory, it gives me errors:
HQL: select svminus1() from Temp c where c.id=1
SQL: select svminus1() as col_0_0_ from LIS.TBCONTROL controldat0_ where (controldat0_.CONTROLID=1000001221 )
COM.ibm.db2.jdbc.DB2Exception: [IBM][CLI Driver][DB2/NT] SQL0440N No authorized routine named "SVMINUS1" of type "FUNCTION"
having compatible arguments was found. SQLSTATE=42884
Why am i getting this error?
Also when converting HQL to SQL, it hasn;t replaced my custom function with it's definition.

[Hibernate-JIRA] Commented: (HHH-1759) ClasscQueryTranslator do not make SQL Function substitution
by Steve Ebersole (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1759?page=c... ]
Steve Ebersole commented on HHH-1759:
-------------------------------------
Is this really still the case with WebLogic? are they still leaking their Antlr usage?
@Sandeep Are you using WebLogic too? Is that why you "need" to use the classic parser? Otherwise, why not just use the Antlr based parser?
