[dba-SQLServer]Sproc Output to VB?

It is not necessarily such a clear cut.  I don't use output params at all, but rather return the result of action queries in the form of a recordset (1 row 1 column).  All processing logic sits on the server.

It all becomes a question of which side you want to handle the bulk of the
processing.
By using recordsets, all processing happens on the CLIENT side.
By using output parameters, all processing happens on the SERVER side.

Hello Guys,

In relation to this, I have asked the list previously, but do you find that
using commands and using OutPut parameters are arkward?

I try to avoid using output params if possible, also, I have been recently
using simple recordsets to run action sp's with nice tidy results.

It means that the parameters are loosely typed, but I am happy enough with
it,

any comments ?


Mark
