The ORA-06502 error is raised ONLY
after the Oracle server
patch 9.2.0.6 installation.
Repeated call of any
functions containing at least one
VARCHAR2 type parameter (if the parameter value is greater then one in
the first call
) raises this error.
Example:
in Oracle (SCOTT/TIGER schema):
sql:
create or replace function get_deptno(in_dname varchar2, in_loc varchar2) return number as
v_return number;
begin
select
sd.deptno into v_return
from dept sd
where sd.dname = in_dname
and sd.loc = in_loc;
return(v_return);
end;
in Delphi:
dfm:
object OraStoredProc1: TOraStoredProc
StoredProcName = 'SCOTT.GET_DEPTNO'
Session = OraSession1
SQL.Strings = (
'begin'
' :RESULT := SCOTT.GET_DEPTNO(:IN_DNAME, :IN_LOC);'
'end;')
Debug = True
Left = 132
Top = 8
ParamData =
pas:
function TForm1.GetDeptNo(AName, ALoc: string): Integer;
begin
with OraStoredProc1 do
begin
ParamByName('IN_DNAME').AsString := AName;
ParamByName('IN_LOC').AsString := ALoc;
ExecProc;
Result := ParamByName('RESULT').AsInteger;
end;
end;
The first call completes error-free:
debug:
begin
:RESULT := SCOTT.GET_DEPTNO(:IN_DNAME, :IN_LOC);
end;
:RESULT(FLOAT,OUT)=
:IN_DNAME(VARCHAR[5],IN)='SALES'
:IN_LOC(VARCHAR[7],IN)='CHICAGO'
The second call raises the error (LENGTH(IN_DNAME = 'RESEARCH') > LENGTH(IN_DNAME = 'SALES')):
debug:
begin
:RESULT := SCOTT.GET_DEPTNO(:IN_DNAME, :IN_LOC);
end;
:RESULT(FLOAT,OUT)=30
:IN_DNAME(VARCHAR[8],IN)='RESEARCH'
:IN_LOC(VARCHAR[6],IN)='DALLAS'
