Re: Subprocedure Question

Fastest completion of project:  Chain to the item master
Fastest performance:  Chain to the item master
Easiest maintenance:  Chain to the item master.  Now that last one will 
start a raging debate.  However I've worked with vendor software that 
changed the properties of every field you mentioned.  And you aren't going 
to skip by without maintaining the client program that uses the chain, sql 
or externalization.  Unless you put some silly restrictions on the use of 
the new version like not allowing anyone to take advantage of the larger 
field sizes.

Where externalization might buy you something is in potential reduction of 
complexity.  For instance instead of a simple GetItemClass you had a 
GetThisReallyComplexAnalysis subprocedure where you pass it the item 
number and it spewed out the result.  Then again, you could take this 
subprocedure, make it a UDF, create a sql view that includes this UDF and 
then simply read from this view.
