Hi friends,

Please suggest some ideas to pass the dynamically creating values to Store procedure through SQL parameters?

I want to save those values into table where that table is also created dynamically.

Thanks

Solution 2

Long back I wrote a procedure that was taking XML string and then using the passed XML to find real data. Perhaps that could do.

Also using the XML is not so different from the above solution, so you could use that too. That solution is structuring data using our own format and using XML will also do the same.

Not clear. How would you parse XML in SQL?

It's not really very easy, since SQL does not have any concept of arrays.
However, you could pass them through as a delimited string, and break it into a temporary table in your procedure:
Pass a list as a string parameter:

SQL

DECLARE @INSTR as VARCHAR(MAX)
SET @INSTR = '2,3,177,'
DECLARE @SEPERATOR as VARCHAR(1)
DECLARE @SP INT
DECLARE @VALUE VARCHAR(1000)
SET @SEPERATOR = ','
CREATE TABLE #tempTab (id int not null)
WHILE PATINDEX('%' + @SEPERATOR + '%', @INSTR ) <> 0 
BEGIN
   SELECT  @SP = PATINDEX('%' + @SEPERATOR + '%',@INSTR)
   SELECT  @VALUE = LEFT(@INSTR , @SP - 1)
   SELECT  @INSTR = STUFF(@INSTR, 1, @SP, '')
   INSERT INTO #tempTab (id) VALUES (@VALUE)
END
SELECT * FROM myTable WHERE id IN (SELECT id FROM #tempTab)
DROP TABLE #tempTab
