OpenLDAP+Oracle10g

[ZhangPu <zhang@fjh.fujitsu.com>]

Hello

I'm testing with OpenLDAP+Oracle10g.

When I wrote the sql like below:

CREATE OR REPLACE FUNCTION create_person RETURN number AS
keyval number;
BEGIN
INSERT INTO persons (id,name) VALUES (person_ids.nextval,' ');
select max(id) into keyval from persons;
RETURN keyval;
END;
/

insert into ldap_oc_mappings (id,name,keytbl,keycol,create_proc,delete_proc,expect_return) 
values (1,'inetOrgPerson','persons','id','create_person()','delete_person(?)',0);

Or 
insert into ldap_oc_mappings (id,name,keytbl,keycol,create_proc,delete_proc,expect_return) 
values (1,'inetOrgPerson','persons','id','exec :keyval:=create_person()','delete_person(?)',0);

Or 
insert other values which can be run without problem by sql*plus to 
ldap_oc_mappings.create_proc.

If I run ldapadd, ORACLE server returns a same error for every value.
--------
backsql_add("cn=test,o=sql,c=ru"): create_proc execution failed
Return code: -1
   Native error code: 900
   SQL engine state:  51
   Message:           [unixODBC][DataDirect][ODBC 20101 driver][20101]ORA-00900: invalid SQL statement


Does anyone know this? Help me please.

Best regards
Pu
