Subj:   ALTER PROCEDURE COMPILE
 
From:   David Clough

Hi guys,

During an upgrade of Teradata I read that using

     Alter Procedure  Compile ;

is the way to go.

That's fine, but does this handle dependencies, I wonder ?

For example if I have 5 Procedures, with the following dependencies :

Proc_A ... invokes Proc_E

Proc_B ... invokes Proc_D

Proc_C

Proc_D

Proc_E


If we generate a Bteq script with the Alters in this order

     Alter Procedure Proc_A ?Compile ;

     Alter Procedure Proc_B ?Compile ;

     Alter Procedure Proc_C ?Compile ;

     Alter Procedure Proc_D ?Compile ;

     Alter Procedure Proc_E ?Compile ;

then, whilst it is self-evident that Procedure C , D and E would independently compile, would the PRECEDING Procedures (i.e. A and B) fail to compile first time around ? ?

Effectively, would I have to run the script again in order for A and B to then compile ? ?
