将xml数据插入表存储过程sql server

2021-09-10 00:00:00 sql tsql sql-server

我有以下格式的xml

 <Entity>
    <name>John</name>
    <aliases><alias>Johnny</alias></aliases>
    <aliases><alias>Johnson</alias></aliases>
    </Entity>
    <Entity>
    <name>Smith</name>
    <aliases><alias>Smithy</alias></aliases>
    <aliases><alias>Schmit</alias></aliases>
    </Entity>

我想将它们插入表中，因此在示例中该表应该有 4 条记录.

I want to insert them in table so the table should have 4 records in the example.

列是名称和别名.

name | alias
John | Johnny
John | Johnson
Smith| Smithy
Smith| Schmit

如何使用游标或其他方式实现此目的?

How can I achive this using cursor or something else?

我尝试过的.在实体的光标中，我尝试插入别名值，但只采用第一个别名.

What i have tried. In cursor for entity i try insert alias value,but only first alias is taken.

insert into  TESTTABLE
            (EntityID,Alias)
        select 
            @EntityID as EntityID,
            Alias
        from OpenXml(@ixml, '/Aliases',2)
        with (
            Alias varchar(255) '.'
        )

推荐答案

DECLARE @XML AS XML= N'
<Entity>
    <name>John</name>
    <aliases><alias>Johnny</alias></aliases>
    <aliases><alias>Johnson</alias></aliases>
    </Entity>
    <Entity>
    <name>Smith</name>
    <aliases><alias>Smithy</alias></aliases>


     <aliases><alias>Schmit</alias></aliases>
        </Entity>'

INSERT INTO @tblTest(firstName,LastName)
        SELECT  t1.c.value('../name[1]','varchar(100)') As FirstName,t1.c.value('alias[1]','varchar(50)') as SecondName

    FROM @xml.nodes('/Entity/aliases') t1(c)
