I need to pass an array of "id's" to a stored procedure, to delete all rows from the table EXCEPT the rows that match id's in the array.
How can I do it in a most simple way?
Use a stored procedure:
EDIT: A complement for serialize List (or anything else):
List<string> testList = new List<int>();
testList.Add(1);
testList.Add(2);
testList.Add(3);
XmlSerializer xs = new XmlSerializer(typeof(List<int>));
MemoryStream ms = new MemoryStream();
xs.Serialize(ms, testList);
string resultXML = UTF8Encoding.UTF8.GetString(ms.ToArray());
The result (ready to use with XML parameter):
<?xml version="1.0"?>
<ArrayOfInt xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<int>1</int>
<int>2</int>
<int>3</int>
</ArrayOfInt>

Passing XML as parameter:
<ids>
<id>1</id>
<id>2</id>
</ids>
CREATE PROCEDURE [dbo].[DeleteAllData]
(
@XMLDoc XML
)
AS
BEGIN
DECLARE @handle INT
EXEC sp_xml_preparedocument @handle OUTPUT, @XMLDoc
DELETE FROM
YOURTABLE
WHERE
YOUR_ID_COLUMN NOT IN (
SELECT * FROM OPENXML (@handle, '/ids/id') WITH (id INT '.')
)
EXEC sp_xml_removedocument @handle
