SQL: Dynamic Variable Names

Question

I am attempting to set variables whose names are dynamic in a stored procedure:

DECLARE @var01 varchar(50)  
DECLARE @var02 varchar(50) 
...
DECLARE @var30 v         


        

Answer 1

Since you are saying in comments that you are assigning the set of variables merely to insert the assigned values into a table, you could use an approach avoiding the variables altogether. You could insert all the values into a temporary table or table variable, providing them with numeric indices, then pivot the column of values and insert the resulting row into the target table. So, something like this:

DECLARE @values TABLE (Ind int IDENTITY(1,1), Value varchar(50));

INSERT INTO @values
SELECT ...
;

INSERT INTO TargetTable (Col1, Col2, ..., Col30)
SELECT [1], [2], ..., [30]
FROM @values
PIVOT (
  MAX(Value) FOR Ind IN ([1], [2], ..., [30])
) AS p
;

I even suspect there might also be a possibility to do everything in such a way as to avoid the cursor you are mentioning in comments.
