Re: SQL Stored Procedure with variable table names

[rob@xxxxxxxxx]

I haven't done any native stored procedures.  Normally I do them in RPG. 
In RPG I would have to consider one of 2 items:

1)  lib would have a prefix of a colon to denote it as a variable.  Like 
(but different):
fetch c1 into :lib;
...
insert into :lib.table123...

2)  Does a native stored procedure support PREPARE or EXECUTE IMMEDIATE? 
Then you could construct the statement on the fly.

SQL Stored Procedure with variable table names






Does anyone know of a way to use a variable in a stored procedure as the 
table name? When I run the procedure, it always tries to use lib not the 
contents of the variable.

I am tying to update a specific table in every library that it exists. 
Here is a sample of the code:

DECLARE lib VARCHAR(128);
DECLARE c1 Cursor FOR
                 SELECT table_schema 
                                 FROM SYSIBM.TABLES 
                                 WHERE table_name = 'TABLE123';
 
FETCH c1 INTO lib;
WHILE at_end = 0 DO
                 INSERT INto lib.TABLE123 VALUES('A','B','C');
                 FETCH c1 INTO lib;
END WHILE;


Thanks,
