How to use multiple values for IN clause using same parameter (SQL Server)

Old Approach :

Declare  @SQL         VARCHAR(MAX)

Declare  @WhereClause VARCHAR(MAX)

Set @WhereClause='Bob,Hulda,Jacoba'

SET @WhereClause=REPLACE(@WhereClause,',',''',''')

Set @SQL='Select *

from dbo.[Student]

Where  [Student Name] In (''' + @WhereClause + ''')'

EXEC (@SQL)

New Approach :

Declare  @Xml AS XML

Declare  @WhereClause VARCHAR(MAX)

Set @WhereClause='Bob,Hulda,Jacoba'

SET @Xml = cast(('<A>'+replace(@WhereClause,',' ,'</A><A>')+'</A>') AS XML)

Select *

from dbo.[Student]

Where  [Student Name] In (

SELECT A.value('.', 'varchar(max)') as [Column] FROM @Xml.nodes('A') AS FN(A)

)

How To Get the Deleted Records Back in SQL Server

CREATE TABLE [dbo].[Student](

[Sno] [int] NOT NULL,

[Student name] [varchar](50) NOT NULL,

[Date of Birth]  datetime not null,

[Grade] [char] (4) not null,

[Marks] [int] NULL)

--Inserting data into table

Insert into dbo.[Student] values (1,'Bob jerry','1974-12-31','VI',89)

--Check the existence of the data

Select * from dbo.[Student]

--Delete the record

Delete from dbo.[Student]

--Verify the data has been deleted

Select * from dbo.[Student]
