How to SELECT FROM stored procedure

How to SELECT FROM stored procedure 📝💻

So, you've got a stored procedure that is returning rows? 🤔 And now you're wondering if it's possible to select the output by calling this procedure directly, without any additional hassle? 🤷‍♂️ Well, you're in luck! In this blog post, we'll explore common issues, provide easy solutions, and show you how to do exactly that! 💪

The Stored Procedure 🧪

Let's take a look at the stored procedure in question:

CREATE PROCEDURE MyProc
AS
BEGIN
    SELECT * FROM MyTable
END

Seems pretty straightforward, right? But what if you want to select the output of this procedure? Can we simply do something like this?

SELECT * FROM (EXEC MyProc) AS TEMP

The Challenge 🤔

As much as we would love for this solution to work seamlessly, unfortunately, it's not that simple. 😕 The syntax SELECT * FROM (EXEC MyProc) won't give you the desired result. But fear not! We have a couple of simple solutions to this problem. 👍

Solution 1: Using INSERT INTO 📥

One way to achieve the desired result is by using the INSERT INTO statement. Here's how it works:

CREATE TABLE #TempTable (
    -- Define columns here
)

INSERT INTO #TempTable
EXEC MyProc

SELECT * FROM #TempTable

What we're doing here is creating a temporary table (#TempTable) with the desired column structure. Then, we use the INSERT INTO statement along with the EXEC command to execute the stored procedure and insert the result into our temporary table. Finally, we can simply select from the temporary table to get our desired output! 🎉

Solution 2: Using OPENROWSET 🚪

Another way to achieve the same result is by using the OPENROWSET function. Here's how it works:

SELECT *
FROM OPENROWSET('SQLNCLI', 'Server=(local);Trusted_Connection=yes;',
                'EXEC MyProc') AS Result

In this solution, we utilize the OPENROWSET function, specifying the server name and trusted connection, followed by the EXEC MyProc statement. This allows us to select the output directly, without the need for temporary tables.

Taking it Further 🚀

Now that you know how to select from a stored procedure, you might want to take it even further! Maybe you want to implement paging using SELECT TOP X, ROW_NUMBER, and an additional WHERE clause, without passing these values as parameters. Here's a little bonus tip for you! 😉

WITH CTE AS (
    SELECT *,
           ROW_NUMBER() OVER (ORDER BY SomeColumn) AS RowNum
    FROM (EXEC MyProc) AS ProcResult
)
SELECT *
FROM CTE
WHERE RowNum BETWEEN 1 AND X

In the example above, we use a common table expression (CTE) to apply the ROW_NUMBER() function to the result of the stored procedure. We then use the BETWEEN clause in the final SELECT statement to implement paging, selecting the desired range of rows.

Wrap Up and Engage! 🎉
