Stored Procedure in WebI Reports Part 3

| June 27, 2009

Image walkthrough: Stored Procedure with Parameters / Prompts in WebI Reports
[1] We are starting with this WebI report which was created with a simple stored procedure, in Part 2: That stored procedure just returned 2 columns. Now, we are going to work with a stored procedure with 2 input parameters, aka ‘prompts’ (in WebI). Very useful.

[2] Our 2nd stored procedure returns 2 columns, based on users’ response. The parameters are ‘StateID’ and ‘StateAbbrev’ – with datatype of number and string / varchar, respectively. And since we know where these 2 fields are from, a quick way to test this procedure would be to find and enter 2 valid parameters when executing the procedure, in this case, we’ll pick ‘3’ for state ‘AR’.
Let’s run the procedure:
Usage format:
EXEC Stored_Procedure StateID, StateAbbrev
EXEC Stored_Procedure 3, AR
> see results of this procedure at the bottom of the following pic
[3] So, back to WebI > SQL (View SQL) > Use Custom SQL:
We’ll apply our store procedure: EXEC Stored_Procedure 3, AR
make sure, to use “SET NOCOUNT ON” and comment out (/* blah blah */) the codes generated by WebI – do NOT delete the codes.
Validation successful.

[4] Run it and the report runs. So, we got it to work. Don’t worry about the column headers, you can rename them to suit your needs.
Now, let’s create prompts.
[5] We’ll use both types to be Alphanumeric
This your basic @Prompt syntax:
@Prompt(‘message’,‘type’,[lov],[MONO|MULTI],[FREE|CONSTRAINED])
So we have
— EXEC Stored_Procedure 3, AR (Original format)
EXEC Stored_Procedure
@Prompt(‘Enter STATE ID’ , ‘A’ , MONO , FREE , PERSISTENT) ,
@Prompt(‘Enter STATE ABBREVIATION’ , ‘A’, MONO , FREE , PERSISTENT)
… And validation successful. Great.
[6] As we save and run the above modified WebI query, we are prompted – perfect! So, we’ll once again enter ‘3’ and ‘AR’ to match with the results we got when we ran this procedure on SQL M our result in SQL Server Management Studio.

[7] So, now let’s run this stored procedure with prompts on WebI – bingo, Success!
[8]NOTE:
If you go back to the code, you’ll see that the @Prompts are gone in custom SQL query. Don’t worry, simply “close” the code and the report will still prompt you. BUT, if you hit “save”, then it will only retain the value you see – in this case ‘3’ and ‘AR’.
