Oracle错误：ORA-00900：无效的SQL语句

Question

我正在尝试使用2个函数创建以下数据类型：

-- 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说明

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TYPE BODY定义中的功能描述之一。

我尝试在最后一个END;之后添加/ END; 但这无助于解决问题。

更换FLOAT(2)只有FLOAT ：

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： http : //docs.oracle.com/cd/B28359_01/appdev.111/b28370/create_function.htm RETURN数据类型

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PL / SQL支持的任何数据类型。
......
......
数据类型不能指定长度，精度或小数位数。 数据库从调用函数的环境中得出返回值的长度，精度或小数位数。
