Question

我尝试在Oracle Apex 5，SQL命令中创建此功能，并导致此错误＆＃39; ORA-24344：编译错误成功。＆＃39;你为什么这么认为？我试图创建一个随机生成的代码。

CREATE OR REPLACE FUNCTION generate_code()
    return varchar2
    AS
    code varchar2;
    BEGIN
    code := DBMS_RANDOM.value(1,100);
    return code;
    END;

Answer 1

语法错误，见下文

正确的语法是

CREATE OR REPLACE FUNCTION generate_code

    return varchar2
    AS
    code varchar2(100);
    BEGIN
    code := DBMS_RANDOM.value(1,100);
    return code;
    END;

包含错误说明的原始语法：

SQL> CREATE OR REPLACE FUNCTION generate_code()
  2
  3      return varchar2
  4      AS
  5      code varchar2;
  6      BEGIN
  7      code := DBMS_RANDOM.value(1,100);
  8      return code;
  9      END;
 10
 11  /

Warning: Function created with compilation errors.

SQL> show error
Errors for FUNCTION GENERATE_CODE:

         following:

         current delete exists prior

功能创建时编译错误成功，为什么？
