Oracle错误:ORA-00900:无效的SQL语句 [英] Oracle ERROR: ORA-00900: invalid SQL statement

问题描述

我正在尝试使用2个函数创建以下数据类型:

I am trying to create the following datatype with 2 functions:

-- Employee

CREATE OR REPLACE TYPE EmployeeType AS OBJECT (
    EmployeeNumber NUMBER,
    EmployeeName VARCHAR2(150),
    EmployeeAddress VARCHAR2(255),
    MAP MEMBER FUNCTION getEmployeeNumber RETURN NUMBER,
    MEMBER FUNCTION CalculateSalary RETURN FLOAT(2)
)
NOT FINAL;
CREATE OR REPLACE TYPE BODY EmployeeType AS

    MAP MEMBER FUNCTION getEmployeeNumber RETURN NUMBER IS
    BEGIN
        RETURN EmployeeNumber;
    END;
     -- function that can be overriden by subtypes, make abstract
    MEMBER FUNCTION CalculateSalary RETURN FLOAT(2) IS
    BEGIN
         -- function returns empty, has to be overwritten by fulltimeemployee
        RETURN 0.00;
    END;
END; 

但是我不断收到错误提示

However I keep getting an error stating

ERROR: ORA-00900: invalid SQL statement

Error Code: 900

Query = END

我正在使用RazorSQL执行查询，我似乎无法获取导致此错误的行号，但是通过反复试验，我发现它是我的TYPE BODY定义中的功能描述之一.

I am using RazorSQL to execute my queries, I cant seem to get the line number causing this error but through trial and error I have found it to be one of the function descriptions in my TYPE BODY definition.

我尝试在最后一个END;之后添加/，但这无助于解决问题.

I have tried adding / after the last END; but it does not help solve the issue.

推荐答案

仅用FLOAT替换FLOAT(2):

CREATE OR REPLACE TYPE EmployeeType AS OBJECT (
    EmployeeNumber NUMBER,
    EmployeeName VARCHAR2(150),
    EmployeeAddress VARCHAR2(255),
    MAP MEMBER FUNCTION getEmployeeNumber RETURN NUMBER,
    MEMBER FUNCTION CalculateSalary RETURN FLOAT
)
NOT FINAL;
/
CREATE OR REPLACE TYPE BODY EmployeeType AS

    MAP MEMBER FUNCTION getEmployeeNumber RETURN NUMBER IS
    BEGIN
        RETURN EmployeeNumber;
    END;
     -- function that can be overriden by subtypes, make abstract
    MEMBER FUNCTION CalculateSalary RETURN FLOAT IS
    BEGIN
         -- function returns empty, has to be overwritten by fulltimeemployee
        RETURN 0.00;
    END;
END; 
/

CREATE TYPE的文档没有提及此内容，但是您可以在与CREATE FUNCTION相关的主题中找到说明:

The documentation for CREATE TYPE doesn't mention this, but you can find the explanation in the topic related to CREATE FUNCTION : http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/create_function.htm RETURN datatype

RETURN数据类型
对于数据类型，请指定函数返回值的数据类型.返回值可以具有任何数据类型 受PL/SQL支持.
......
......
数据类型无法指定长度，精度或小数位数. 数据库得出返回值的长度，精度或小数位数 来自调用该函数的环境.

RETURN datatype
For datatype, specify the data type of the return value of the function. The return value can have any data type supported by PL/SQL.
......
......
The data type cannot specify a length, precision, or scale. The database derives the length, precision, or scale of the return value from the environment from which the function is called.
