ORA-25463: table alias not specified
Cause: An attempt to evaluate was made, which failed because one of the table values specified had a NULL alias name.
Action: Check the list of table values, and try again with a valid alias name.
ORA-25463错误提示表别名没有指定。Oracle数据库查询语句中,表别名是必须指定的,没有指定将会引发ORA-25463错误。
当用户查询语句中没有为相应表指定别名时,数据库会总是给用户返回ORA-25463错误。
SELECT *
FROM product
1、添加表别名以解决ORA-25463错误。
如:
SELECT *
FROM product p –指定了表别名P
