Question

below is the stored proc I wrote:

create or replace procedure test005
as
begin

CREATE GLOBAL TEMPORARY TABLE TEMP_TRAN 
( 
COL1 NUMBER(9), 
COL2 VARCHAR2(30), 
COL3 DATE 
) ON COMMIT PRESERVE ROWS 

/
INSERT INTO TEMP_TRAN VALUES(1,'D',sysdate); 

INSERT INTO TEMP_TRAN VALUES(2,'I',sysdate); 

INSERT INTO TEMP_TRAN VALUES(3,'s',sysdate); 

COMMIT;
end;

when i executed it , i get an error message mentioning:

create or replace procedure test005
as
begin

CREATE GLOBAL TEMPORARY TABLE TEMP_TRAN 
( 
COL1 NUMBER(9), 
COL2 VARCHAR2(30), 
COL3 DATE 
) ON COMMIT PRESERVE ROWS 

/
INSERT INTO TEMP_TRAN VALUES(1,'D',sysdate); 

INSERT INTO TEMP_TRAN VALUES(2,'I',sysdate); 

INSERT INTO TEMP_TRAN VALUES(3,'s',sysdate); 

COMMIT;
end;
Error at line 1
ORA-00955: name is already used by an existing object

Script Terminated on line 1.

I tried to drop the TEMP_TRAN and it says table doesn’t exist. So there is no TEMP_TRAN table existed in system. why am I getting this error? I am using TOAD to create this stored proc.

Any help would be highly appreciated.

Global temporary tables are not meant to be created “on the fly” by stored procedures. They are to be created once, permanently, like any other table. It is the data that is temporary, not the table object.

Regarding TEMP_TRAN, perhaps an object of that name exists, but is not a table? Try this:

select * from all_objects where object_name = 'TEMP_TRAN';
