Question

I have a table named assignRole.

I am passing string of userid (int) csv ,and passing roleid(int).

I want a stored procedure which split userid from string and take roleid and insert these values in table.this thing is to happen for all values in userid string.

Answer 1

First, create a function:

CREATE FUNCTION [dbo].[SplitInts]
(
   @List       VARCHAR(MAX),
   @Delimiter  CHAR(1)
)
RETURNS TABLE
WITH SCHEMABINDING
AS
   RETURN ( SELECT Item = CONVERT(INT, Item) FROM ( 
     SELECT Item = x.i.value('(./text())[1]', 'int') FROM ( 
       SELECT [XML] = CONVERT(XML, '<i>' + REPLACE(@List, @Delimiter, '</i><i>') 
       + '</i>').query('.') ) AS a CROSS APPLY [XML].nodes('i') AS x(i)) AS y
     WHERE Item IS NOT NULL
   );

Now you can say:

INSERT dbo.assignRole(RoleID, UserID)
  SELECT @RoleID, Item
  FROM dbo.SplitInts(@UserIDList, ',');
