CREATE Procedure GroupStudentNames
@Student_List Varchar(2000),
@Out_Delimiter Varchar(10),
as
Begin
Set NoCount On
Declare @Name_List Varchar(6000)
Declare @SQLString NVarchar(4000)
SET @SQLString = N'Select @Name_OUT = Coalesce(@Name_OUT+@Delimiter,'') +
StudentName From Student
Where
Stud_Id in (' + @Student_List +')'
EXECUTE sp_executesql
@SQLString,
N'@Delimiter Varchar(10),@Name_OUT Varchar(6000) OUTPUT',
@Delimiter = @Out_Delimiter,@Name_OUT = @Name_List OUTPUT
-- The same query can be done by using EXEC
-- sp_executeSQL has advantage than using EXEC
-- In sp_executeSQL, SQL server likely to resuse the Execution Plan generated
Select @Name_OUT As 'StudentName' -- which gives student names seperated by the given delimiter
