Passing quotation mark in parameter

Question

Hi,
I have one query which I migrated from sql server database. It is given below. I am passing single quote mark as a parameter to this query but it always retrieves 0 as count. But I have 1 record in table. As a solution to this I have resolved this issue for sql server by passing two quotation mark (replacing single quotation mark with double quotation mark). This same solution applies here too. when I pass any parameter with single quote in it, it will replace single quote with double quote and then pass it to the below given procedure. But still it is not working correctly. I have similar query for retrieving that record and it is working fine. Any idea why the below query is not working correctly?
PROCEDURE GetEntUserGroupCountWithOther
ppGroupName IN VARCHAR2 DEFAULT '%' ,
cp1 IN OUT SYS_REFCURSOR
AS
BEGIN
OPEN cp1 FOR
SELECT COUNT(*) TotalRecords
FROM ( SELECT Id EnterpriseUserGroupId,
Name NAME,
Description DESCRIPTION,
IsDefault
FROM EnterpriseUserGroup ) T1
WHERE UPPER(NAME) LIKE +UPPER('%' || ppGroupName || '%');
END;
Thanks,

Answer 1

not sure what your question is, seems to work
create table EnterpriseUserGroup
(name varchar2(10))
insert into EnterpriseUserGroup values ('Hello');
insert into EnterpriseUserGroup values ('World');
insert into EnterpriseUserGroup values ('''');
commit;
create or replace
PROCEDURE GetEntUserGroupCountWithOther
(ppGroupName IN VARCHAR2 DEFAULT '%'
,cp1 IN OUT SYS_REFCURSOR
AS
BEGIN
   OPEN cp1 FOR
      SELECT COUNT(*) TotalRecords
        FROM EnterpriseUserGroup T1
       WHERE UPPER(NAME) LIKE UPPER('%' || ppGroupName || '%');
end;
/and to test it
SQL> var rc refcursor
SQL>
SQL>
SQL> begin
  2     GetEntUserGroupCountWithOther ('''', :rc);
  3  end;
  4  /
PL/SQL procedure successfully completed.
SQL> print
TOTALRECORDS
           1
SQL> begin
  2     GetEntUserGroupCountWithOther ('hello',  :rc);
  3  end;
  4  /
PL/SQL procedure successfully completed.
SQL> print
TOTALRECORDS
           1
SQL> begin
  2     GetEntUserGroupCountWithOther ('not there',  :rc);
  3  end;
  4  /
