在Oracle中使用XMLTYPE解析模式,可以通过以下步骤进行:
ALTER TABLE table_name ADD xml_column_name XMLTYPE;
INSERT INTO table_name (xml_column_name) VALUES (XMLTYPE('<root><element>value</element></root>'));
```sql
SELECT xml_column_name.EXTRACT('/root/element/text()').getStringVal() FROM table_name;
```
```sql
SELECT xml_column_name.EXISTSNode('/root/element') FROM table_name;
```
```sql
SELECT XMLQuery('/root/element/text()' PASSING xml_column_name RETURNING CONTENT) FROM table_name;
```
UPDATE table_name SET xml_column_name = xml_column_name.UPDATEXML('/root/element/text()', 'new_value') WHERE condition;
DELETE FROM table_name WHERE xml_column_name.EXISTSNode('/root/element') = 1;
XMLTYPE解析模式在以下场景中非常有用:
