ORA-01469: PRIOR can only be followed by a column name
Cause: Attempting to specify “PRIOR ” where is not a column name.
Action: Only a column name can follow PRIOR. Replace with a column name.
ORA-01469: PRIOR 语句只允许后跟一个列名。
这个错误指出你使用了不正确的包装结构:PRIOR 后面只能跟一个列名。
The PRIOR operator is only allowed to be followed by a column name. The PRIOR operator has to be used to assign a value to the current row.
该错误常常出现在对一个列使用 PRIOR 操作符,单独使用时无效。
因为我们在编写SQL语句时,必须要用到PRIOR操作符,所以必须要保证它的使用的合法性:该操作类只能后跟一个列名。比如:
SELECT PRIOR COLUMN_NAME FROM TABLE_NAME;
