SELECT FROM stored procedure? - sql

Question

If I have a stored proc in SQL Server 2008, I know I can run it from management studio like so:
exec rpt_myproc #include_all = 1, #start_date = '1/1/2010'
But I'm using an ad-hoc query tool that wasn't returning any results. So I asked it to give me the SQL it was running and it returns this:
SELECT DISTINCT TOP 100000
[dbo].[rpt_myproc].[company_name] AS 'company name',
[dbo].[rpt_myproc].[order_number] AS 'order number]
FROM [dbo].[rpt_myproc]
WHERE
([dbo].[rpt_myproc].[PARAM_start_date] IN ('1/1/2010'))
AND ([dbo].[rpt_myproc].[PARAM_include_all] IN ('1'))
I'm not familiar with that syntax. Is that even possible? The ad-hoc tool isn't failing, but it may be swallowing that error. Then again, maybe it's just giving me a shorthand which it will use translate to the proper syntax later. But if so, why would it give it to me in this form?
I can't seem to get that SQL to execute in Management Studio, so I was wondering if something like that were possible?

I understand that this is more than 3 years old, but in case anybody else is looking for an answer to this question. I had to deal with this reporting platform, Izenda, and have found that stored procedures are treated differently than the output from the "sql" icon. Here is what happens when you select sp as data source
A dynamic sql is build
It creates a two temporary tables with all of the columns that your sp is returning
The first temp table is populated with the result from your stored procedure
The second temp table is populated with the result plus the value of your input parameter.
A statement is created that queries these two temporary tables
Please note that if you don't feed it a parameter it will execute with a default value of empty string '' which will most likely return no data.
In my opinion, horrible idea to handle stored procs which is a good reason why we are planning to drop them for some other reporting solution.

You can insert the first result set of a stored procedure into a temporary table:
SELECT *
INTO #YourProc
FROM OPENROWSET('SQLNCLI',
'server=SERVERNAME\INSTANCENAME;trusted_connection=yes',
'set fmtonly off; exec rpt_myproc')
There's like 3 ways to do this, see this blog post. If you know the output beforehand, you can do it without the remote query.

What tool are you using? You should be able to specify the query type (i.e. SQL, or stored proc, etc)
Haven't used that tool before but a quick google came up with this example (not sure if it will help you)
Using a stored procedure in 5.x
This example uses a stored procedure to populate a table before report design or execution. As shown in the comments, the table StoredProcResults must already exist. Every time a report is created or viewed this stored procedure will update the results of the StoredProcResults table. For 6.x follow these instructions but treat the SP as a regular datasource.
// Customize a report on the fly prior to execution on a per user basis
public override void PreExecuteReportSet(Izenda.AdHoc.ReportSet reportSet){
/*this sample uses the adventure works database Here is the definition of the table and stored procedure created for this report.
CREATE TABLE [dbo].[StoredProcResults](
[ProductID] [int] NOT NULL,
[OrderQuantity] [int] NOT NULL,
[Total] [int] NOT NULL,
[DueDate] [smalldatetime] NOT NULL
) ON [PRIMARY]
CREATE PROCEDURE DoCustomAction (
#date1 as smalldatetime,
#date2 as smalldatetime
) AS
BEGIN
insert into StoredProcResults
select ProductID,OrderQty,LineTotal,ModifiedDate
from Sales.SalesOrderDetail
where ModifiedDate >= #date1 and ModifiedDate <= #date2
END
*/
string currentReportName = HttpContext.Current.Request.QueryString["rn"];
if (currentReportName == "StoredProcExample") {
SqlConnection myConnection = new SqlConnection(Izenda.AdHoc.AdHocSettings.SqlServerConnectionString);
SqlCommand myCommand = new SqlCommand("DoCustomAction", myConnection);
// Mark the Command as a SPROC
myCommand.CommandType = System.Data.CommandType.StoredProcedure;
// Add Parameters to SPROC
SqlParameter parameterdate1 = new SqlParameter("#date1", System.Data.SqlDbType.SmallDateTime);
parameterdate1.Value = "1/1/2003";
myCommand.Parameters.Add(parameterdate1);
SqlParameter parameterdate2 = new SqlParameter("#date2", System.Data.SqlDbType.SmallDateTime);
parameterdate2.Value = "12/31/2003";
myCommand.Parameters.Add(parameterdate2);
try{
myConnection.Open();
myCommand.ExecuteNonQuery();
}
finally{
myConnection.Close();
}
}
}

Are you sure it is a sproc? I've never heard or seen a usage of doing a direct select from a sproc.
What I have seen that works and functions exactly as your code seems to be working is table-valued functions, which are functions, that can take parameters and return a "SELECT FROMable" table just like this (in essence giving you a 'parameterized' view).
