SQL0502N(CURSOR ALREADY OPEN) WHEN TWO FOR LOOPS USE THE SAME CURSOR IN THE SAME PL/SQL ROUTINE |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
If your PL/SQL routine contains two or more FOR loops that use
the same cursor name, error SQL0502N may be reported by DB2 when
the second FOR loop is executed. For example:
set sqlcompat plsql;
set serveroutput on;
create table test1(col1 varchar2(10));
insert into test1 values 'AAA', 'BBB', 'CCC';
create or replace procedure test
is
cursor C1 is select COL1 from TEST1;
begin
for rec in C1
loop
dbms_output.put_line(rec.col1);
end loop;
for rec in C1
loop
dbms_output.put_line(rec.col1);
end loop;
end;
/
begin
test;
end;
/
DB21034E The command was processed as an SQL statement because
it was not a valid Command Line Processor command. During SQL
During SQL processing it returned:
SQL0502N The cursor specified in an OPEN statement is already
open. SQLSTATE=24502 |

| Local-Fix: |
As a workaround, you may use the SELECT form of the FOR loop:
create or replace procedure test
is
begin
for rec in (select COL1 from TEST1)
loop
dbms_output.put_line(rec.col1);
end loop;
for rec in (select COL1 from TEST1)
loop
dbms_output.put_line(rec.col1);
end loop;
end;
/
begin
test;
end;
/
DB20000I The SQL command completed successfully.
