ORA-62007: encountered a value of unsupported type or size for XPath (string)
Cause: A value of an unsupported type was encountered in a SQL/XML operator. SQL/XML operators, such as updateXML, expect value operands of type VARCHAR2 and XMLTYPE. XML DML replication is not supported for SQL/XML DML operators with values of unsupported types or very large values of supported types.
Action: Use event 19027 level 1 to dump XML document instead of XMLDiff in redo log.
这是一个Oracle数据库的错误,它是指在使用XPath(一种XML的路径表达式)解析XML时遇到了不被支持的类型或者大小的取值。
1.检查传入的参数是否符合Oracle支持的XPath数据类型和大小。
2.确认XML文档节点的类型和大小是否属于Oracle支持的范围。
3.遵循正确的XPath语法,如不使用大小写混合,确保字符正确用双引号引起等。
4.确保字符集正确,如网络字符集等。
