Load/Unload XML data in DB2
If XML data in the table is less than 32K for each record, then you can directly unload the data as char. If XML data exceeds 32K for some records, then you have to unload the common data and the XML data separately. First, create a template for unloading XML into a PDS: TEMPLATE LOBFRV DSN 'AAA.BBB.LOB' DSNTYPE(PDS) Then unload XML data using the template: XMLDATA VARCHAR(12345) CLOBF LOBFRV To load XML data from PDS, use “CLOBF” keyword to indicate that the column will be loaded from file, and POSITION(122:150) indicates the file name location in the record file. XMLDATA POSITION(122:150) CHAR CLOBF

1. 基础:对XML进行简单的查询, 插入, 删除, 编辑操作
在数据量不是很大的情况下,可以用xml代替数据库存储数据,但是要定义xsd文件来验证xml文件,保证xml数据格式。
以下网页介绍了如何利用C#实现xml的查询,插入,删除和更新操作,这表明xml可以代替数据库存储一定量的数据。
