Sql 将参数数组传递给存储过程

发布于07月01日

我需要将一个"id"数组传递给存储过程，以便从表中删除除数组中与id匹配的行之外的所有行.

我怎样才能用最简单的方式做到这一点？

推荐答案

使用存储过程:

EDIT:

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());

结果(可与XML参数一起使用):

<?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>

ORIGINAL POST:

将XML作为参数传递:

<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
