Stored procedures with tuples resultset:
SELECT F1,F2,F3 FROM TABL1
And Multi-resultsets stored-procedures:
SELECT F1,F2 FROM TABLE1
SELECT F3,F4,F5 FROM TABLE2
And how can we declare/use variables with PG-SQL ?
With Sybase (and oracle) I can do that:
PROCECURE p (@org_account int, @dest_account int, @amount money)
as
DECLARE @balance money
BEGIN TRAN
SELECT @balance=balance
FROM account_table
WHERE @account_num=@org_account
/* Check if enough money on the account */
IF @balance<@amount
BEGIN
ROLLBACK TRAN
RETURN -1 /* Not enough money */
END
/* proceed with the updates */
...
COMMIT TRAN
RETURN 0
go
How to do a such stored procedure with pgSQL ? (please, don't say me
to write it in C language ).
