Is it possible to execute a stored procedure over a set without using a cursor?

Question

I would like to execute a stored procedure over each row in a set without using a cursor with something like this:

SELECT EXEC dbo.Sproc @Param1 = Table1.i

Answer 1

Take a look at this answer using dynamic SQL. Here is what looks like based on your query.

DECLARE @TSQL NVARCHAR(MAX) = ''
SELECT @TSQL = @TSQL + N'EXEC dbo.Sproc ' + id + '; 
' -- To insert a line break
FROM Table1
EXEC sp_executesql @TSQL

This equals to the following if you PRINT @TSQL. Note that how the line break is inserted.

EXEC dbo.Sproc id1; 
EXEC dbo.Sproc id2; 
EXEC dbo.Sproc id3;
...

If you don't need a stored procedure, it can be easier. I once had a need to update a table based on each row (Code is the column name, and [Value] the value) from a view. Because the view is dynamic and returns different rows each time, and hence different column-value pairs. I re-wrote the query without using any stored procedure.

DECLARE @TSQL NVARCHAR(MAX), @Id VARCHAR(10) = 50

SELECT @TSQL = COALESCE(@TSQL + '''
,','') + Code + ' = ''' + [Value] 
FROM view
WHERE Id = @Id

SET @TSQL = N'UPDATE tableName
SET ' + @TSQL + ''' 
WHERE Id = ' + @Id
PRINT @TSQL
--EXEC SP_EXECUTESQL @TSQL

PRINT @TSQL:

UPDATE tableName
SET Discussed = 'Yes'
,Other = 'Blue'
,IntakeRating = 'H: < $25k'
,IntakeValueEstimate = '25'
,OpportunityDecision = 'Intake'
,Fee = '33 1/3'
,Fee2 = '40'
,IsManager = 'Yes' 
WHERE Id = 50
