How to return the value from a query with SP_EXECUTESQL in a stored procedure

I have a stored procedure that generated a query string and then executes it with

EXECUTE SP_EXECUTESQL @Query

The query, e.g., is: Select Name, Age from tableA, so very simple.

But how to get the result set back from the SP_EXECUTESQL (into a variable?) and then return it as result set in my stored procedure?

You could use a table variable to hold the results of the dynamic SQL call until you are ready to exit the stored procedure. Just before returning from the stored procedure, select the data from the table variable.

DROP PROCEDURE IF EXISTS dbo.MyProc;
GO
CREATE PROCEDURE dbo.MyProc
AS
BEGIN
    --Declare Table variable to hold results of query
    DECLARE @Results TABLE (ResultText VARCHAR(500));
    DECLARE @Query NVARCHAR(30);

    --This is the query
    SET @Query = 'select @@version'

    --Insert the results of the dynamic SQL execution into the table variable
    INSERT INTO @Results
    EXECUTE SP_EXECUTESQL @Query

    --Do more stored procedure logic

    --Finally, select the results of the table variable
    SELECT *
    FROM @Results
END
go
EXEC dbo.MyProc
