Hello,
I have a job that runs over 100 stored procedures daily. Each stored procedure has input tables and output tables.
Just in case there is an issue and one of the stored procedures fails, I'd like to know what other stored procedures have a problem from the failure.
There is a table that lists out the procedure name, table name and indicator (input table or output
create table dbo.test_backup_20180507 (
ID int identity(1,1),
ProcName varchar(100),
TableName varchar(100),
TableType varchar(10))
insert into dbo.test_backup_20180507 values ('Proc 0','A','Input')
insert into dbo.test_backup_20180507 values ('Proc 0','A1','Output')
insert into dbo.test_backup_20180507 values ('Proc 0','A2','Output')
insert into dbo.test_backup_20180507 values ('Proc 1','A1','Input')
insert into dbo.test_backup_20180507 values ('Proc 1','B','Output') <<< this stored procedure failed and table B and C didn't get created correctly.
insert into dbo.test_backup_20180507 values ('Proc 1','C','Output')
insert into dbo.test_backup_20180507 values ('Proc 2','X','Input')
insert into dbo.test_backup_20180507 values ('Proc 2','X1','Output')
insert into dbo.test_backup_20180507 values ('Proc 2','X2','Output')
insert into dbo.test_backup_20180507 values ('Proc 3','C','Input')
insert into dbo.test_backup_20180507 values ('Proc 3','C1','Output')
insert into dbo.test_backup_20180507 values ('Proc 3','C2','Output')
insert into dbo.test_backup_20180507 values ('Proc 4','C2','Input')
insert into dbo.test_backup_20180507 values ('Proc 4','C3','Output')
insert into dbo.test_backup_20180507 values ('Proc 4','C4','Output')
Is there a way to find all the stored procedures that uses the output table from the failed stored procedure using a recursive query?
In this case Proc 1 failed, so that output table B and C didn't get created correctly. Output table C is then used in Proc 3 and the output table of Proc 3 (which is C2) is used in Proc 4.
So the output results from the recursive query should be.. when the failed procedure is Proc 1?
ID ProcName TableName TableType
----------------------------------------------------------------------
4 Proc 1 A1 Input
5 Proc 1 B Output <<< Proc 1 failed and table B and C didn't get created correctly.
6 Proc 1 C Output
10 Proc 3 C Input
11 Proc 3 C1 Output
12 Proc 3 C2 Output
13 Proc 4 C2 Input
14 Proc 4 C3 Output
15 Proc 4 C4 Output
This results will tell me that after fixing Proc 1, I need to rerun Proc 3 and Proc 4
Thank you for your help

I don't think you need recursion from this. But from the table you posted you have no way of ordering the rows so you couldn't know that A1 is correct. You need a way to know the order of tables being updated for a given procName.

thanks for the reply. I ended up using a recursive stored procedure. See attached and let me know if you have any comments. Thanks again
