推荐答案

[]

对于UPDATE,INSERT和DELETE语句,返回值是受命令影响的行数。对于所有其他类型的语句,返回值为-1。

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. For all other types of statements, the return value is -1.



您说您正在使用函数,函数既不是UPDATE,也不是INSERT,也不是DELETE声明,因此返回值为-1。


You said that you're using functions, and a function is neither an UPDATE, nor an INSERT, nor a DELETE statement, so the return value is -1.
