在存储过程或函数的声明部分,定义一个局部函数,结果在select中使用时报PLS-00231错误。
PLS-00231: function ‘string’ may not be used in SQL
Cause: A proscribed function was used in a SQL statement. Certain functions such as SQLCODE and SQLERRM can be used only in procedural statements.
Action: Remove the function call from the SQL statement. Or, replace the function call with a local variable. For example, the following statement is illegal: INSERT INTO errors VALUES (SQLCODE, SQLERRM); However, you can assign the values of SQLCODE and SQLERRM to local variables, then use the variables in the SQL statement, as follows: err_num := SQLCODE; err_msg := SQLERRM; INSERT INTO errors VALUES (err_num, err_msg);
根据不同的场景选择相应的处理办法:
1.改成赋值操作,aa:=f()
2.把主程序改成包,将函数定义在包里
本文介绍了解决Oracle中PLS-00231错误的方法,该错误通常出现在尝试在SQL语句中使用特定的过程或函数时。文章提供了两种解决方案:一是通过局部变量代替函数调用;二是重构程序结构为包。
