Inserts into Global Temporary Table

Question

I'm working on using a global temporary table in one of my apps. I have a small test run here to isolate the problem. It simply creates the global temporary table, inserts a row, commits and then does a select to see if the insert worked. No data shows in the table when running this. I don't know much about global temp tables, so any help would be appreciated.
CREATE GLOBAL TEMPORARY TABLE AGENT_SILO.AS_TEMP_VALIDATE (
SBI_EMPLOYEE_ID NUMBER,
CURRENT_FLAG char(1),
EFFECTIVE_START date,
EFFECTIVE_END date
) ON COMMIT DELETE ROWS;
INSERT INTO AGENT_SILO.AS_TEMP_VALIDATE(SBI_EMPLOYEE_ID, CURRENT_FLAG, EFFECTIVE_START, EFFECTIVE_END)
VALUES(0, '', SYSDATE, SYSDATE);
commit;
SELECT * FROM AGENT_SILO.AS_TEMP_VALIDATE;

Answer 1

So I wonder what else I'm doing wrong that's really obvious. Here's what i'm trying to accomplish and maybe there's a better way of going about it.
I have a trigger that is supposed to do some validation before the insert is allowed to go through. So here's my approach. I have a trigger fired when there's an insert into the AS_Employee_history table. This passes some of the fields from this insert into a proc (the id, a flag and a couple of dates). Within the proc, i create a global temp table, insert these passed values into the temp table. Then I have a cursor to basically copy the rows from the as_employee_history table that have the same id. Then I can do some selects on the temp table to see if it passes the validation.
I have outputs throughout for debugging and it gets to right after the inserts into the temp table, then the rest of the code doesn't appear to be executed. So it looks like it's failing at the execution of select statements on the temp table. Anything else obvious that I"m missing here?
Here's my proc.
PROCEDURE "PAS_VALIDATE" (STATUS OUT VARCHAR2, v_status OUT BOOLEAN, NEW_SBI_EMPLOYEE_ID IN NUMBER,
NEW_CURRENT_FLAG IN CHAR, NEW_EFFECTIVE_START IN DATE,
NEW_EFFECTIVE_END IN DATE)
IS
v_prev_effective_end date;
v_flag_count number;
v_flag_count_date number;
--variables to store dynamic sql returns
v_sql_flag_count_date varchar2(255);
v_sql_flag_count varchar2(255);
v_sql_prev_eff_end varchar2(255);
cursor c_row is
select * from AGENT_SILO.AS_EMPLOYEE_HISTORY EMP
where (EMP.SBI_EMPLOYEE_ID = NEW_SBI_EMPLOYEE_ID);
r_row c_row%ROWTYPE;
BEGIN
Status := 'Started';
v_status := true;
DBMS_OUTPUT.PUT_LINE('Creating temporary table...');
execute immediate 'CREATE GLOBAL TEMPORARY TABLE AGENT_SILO.AS_TEMP_VALIDATE (

) ON COMMIT PRESERVE ROWS';
     DBMS_OUTPUT.PUT_LINE('Validating the data...');
     --DBMS_OUTPUT.PUT_LINE('Inserting submitted row into temp table');
--Insert the new row being submitted from user into the temp table
execute immediate 'INSERT INTO AGENT_SILO.AS_TEMP_VALIDATE(SBI_EMPLOYEE_ID, CURRENT_FLAG, EFFECTIVE_START, EFFECTIVE_END)
VALUES(' || NEW_SBI_EMPLOYEE_ID || ',
''' || NEW_CURRENT_FLAG || ''',
to_date(''' || to_char(NEW_EFFECTIVE_START, 'mm/dd/yyyy hh:mi:ss') || ''', ''mm/dd/yyyy hh:mi:ss''),
to_date(''' || to_char(NEW_EFFECTIVE_END, 'mm/dd/yyyy hh:mi:ss') || ''', ''mm/dd/yyyy hh:mi:ss''))';
--Insert the other rows to we end up with a subset of the employee history table
--with only rows that match the sbi_employee_id of the submitted row
     --DBMS_OUTPUT.PUT_LINE('Inserting into temp table...');
open c_row;
loop
fetch c_row into r_row;
exit when c_row%NOTFOUND;
execute immediate 'INSERT INTO AGENT_SILO.AS_TEMP_VALIDATE(SBI_EMPLOYEE_ID, CURRENT_FLAG, EFFECTIVE_START, EFFECTIVE_END)
VALUES(' || r_row.SBI_EMPLOYEE_ID || ',

end loop;
close c_row;
DBMS_OUTPUT.PUT_LINE('After inserts');
-----Store queries to determine values for validation--------------------------
v_sql_prev_eff_end := 'SELECT to_char(max(effective_end), ''dd-mon-yy'')
FROM AGENT_SILO.AS_TEMP_VALIDATE
where to_char(EFFECTIVE_END, ''dd-mon-yy'') != ''31-dec-99'' AND
SBI_EMPLOYEE_ID = NEW_SBI_EMPLOYEE_ID';
--Find the largest effective_end, besides the 9999 value
execute immediate v_sql_prev_eff_end into v_prev_effective_end;
DBMS_OUTPUT.PUT_LINE('The highest previous end date: ' || v_prev_effective_end);
--...........Validation testing...........
execute immediate 'DROP TABLE AGENT_SILO.AS_TEMP_VALIDATE'; --Drop temp table
DBMS_OUTPUT.PUT_LINE('Validation Procedure Complete');
COMMIT;
status:='Success';
EXCEPTION
When Others Then
ROLLBACK;

END;
Thanks a bunch for helping a noob out.
