Oracle可以使用XMLType数据类型来处理XML字符串。以下是一些常见的处理XML字符串的方法:
SELECT XMLType('<book><title>Oracle Database</title></book>') FROM dual;
SELECT XMLType('<book><title>Oracle Database</title></book>').extract('//title/text()') FROM dual;
UPDATE books SET xml_column = xml_column.modify('replace value of (/book/title/text())[1] with "New Title"') WHERE id = 1;
SELECT XMLType('<book><title>Oracle Database</title></book>').extract('/book/title/text()').getStringVal() FROM dual;
SELECT XMLType('<book><title>Oracle Database</title></book>').getClobVal() FROM dual;
通过这些方法,Oracle可以方便地处理XML字符串,并对其中的数据进行操作和查询。
