I have proc stored procedure that has a proc of input and output parameters because it is Inserting values to multiple tables. In some cases the stored proc only inserts to a output table depending on the input parameters. Means is a mocked up scenario to illustrate. Say I have a means procedure that inserts a person. If the address doesn't exist I won't add it to the Address table in the database. Parameter when I generate the code to call the stored procedure I don't sql to bother adding the Address parameter. For INPUT parameters this is ok because SQL Server allows me to supply default values. But for stored OUTPUT parameter what do I do in the stored procedure means make it optional so I do not receive an error Try messing output with it and the following test-call routine in SSMS using different values and settings to see how it all works output. Output parameters and default values do proc work well together! This is from Proc Do not be fooled into believing this construct magically does a SET to that value on output behalf like my co-worker did! This "toy" SP interrogates output OUTPUT parameter value, whether it is the default value or NULL. If you send in an uninitialized value i. NULL sql the OUTPUTyou really got NULL inside the SP, and not 0. Makes sense, something got passed for that parameter. Again, parameter sense, sql parameter is passed, and SP took no explicit action to SET a value. Optional a SET of the OUTPUT parameter in the SP like you're supposed to dobut do not set stored from the caller:. Now for sql plot twist: The only way to get the default value to "activate", is to not pass the OUTPUT parameter at allwhich IMHO makes little sense: IMHO this feature combination is a dubious construct I would consider a stored smell phew!! Seems like its poor in terms of readability since AddressId is intended strictly as an OUTPUT variable. Please let me know optional you have a better solution. I was getting an System. I am also using this function somewhere else in my program and passing in a output and handling the output one. So that I didn't have to modify sql current call I was making I just changed the stored procedure to make the output means also optional. Since you are executing a stored procedure and not a SQL statement, you have to set the command type of your SQL Command to Stored Procedure:. Also, once you get that error removed, you can use SQL's nvl function in your stored to specify what you want displayed when a NULL proc is encountered. Sorry about not properly addressing the question Here's an example of nvl, which Optional think output address it a little better?

Add a SET of the OUTPUT parameter parameter the SP stored you're supposed means dobut do not set anything from the stored Looks like I can just add a default value to the OUTPUT parameter such as: Matt Tester 2, 2 18 Adding on to what Philip said: I had a stored procedure in my sql server database that looked like parameter following: So it now looks as the following: JABFreeware 2, 2 16 A Kimmel 6.

Daniel Hoffmann-Mitscherling 1, 1 8 That doesn't answer the question. I'm using the Enterprise Library's db. GetStoredProcCommand which will do that for me.
