Question

你好堆栈溢出我是sql的新手，我试图创建一个程序来添加新的顾问。我将重新使用顶点应用程序中的代码，并带有一个按钮来执行任务。此外，我已实施序列添加到顾问的新条目。不幸的是我有错误

编译失败，第10行（11:48:18） PLS-00103：遇到了符号＆＃34; BEGIN＆＃34;当期待以下之一时：使用外部确定性parallel_enable流水线result_cache可访问

将authid作为群集顺序

我可以获得一些指导来解决这个问题，因为我对sql感谢新手并且研究没有帮助。

原始代码

create or replace procedure hirecst
       (CST_NAME VARCHAR2,
        START_DATE DATE,
        LEAVE_DATE DATE,
        LOCATION VARCHAR2,
        SPECIALIST_AREA VARCHAR2)

    RETURN NUMBER IS
       new_cst NUMBER;
    BEGIN
       SELECT CONSULTANT_IDSEQ.NEXTVAL
          INTO new_cst
          FROM DUAL;
       INSERT INTO LDS_CONSULTANT (CONSULTANT_ID, CST_NAME, START_DATE, LEAVE_DATE, LOCATION, SPECIALIST_AREA)
          VALUES (new_cst, p_con_name, p_con_start, p_con_end, p_con_loc, p_con_spec);

       RETURN(new_cst);
    END;

删除了返回

create or replace procedure hirecst
   (CST_NAME VARCHAR2,
    START_DATE DATE,
    LEAVE_DATE DATE,
    LOCATION VARCHAR2,
    SPECIALIST_AREA VARCHAR2)



BEGIN
new_cst NUMBER;
   SELECT CONSULTANT_IDSEQ.NEXTVAL
      INTO new_cst
      FROM DUAL;
   INSERT INTO LDS_CONSULTANT (CONSULTANT_ID, CST_NAME, START_DATE, LEAVE_DATE, LOCATION, SPECIALIST_AREA)
      VALUES (new_cst, p_con_name, p_con_start, p_con_end, p_con_loc, p_con_spec);


END;

注意：我忽略了声明的参数名称与INSERT语句中使用的参数名称之间的明显不匹配。

As documented in the manual您需要AS（或IS）关键字来启动实际的过程部分 - 之后需要编写变量声明：

create or replace procedure hirecst
   (CST_NAME VARCHAR2,
    START_DATE DATE,
    LEAVE_DATE DATE,
    LOCATION VARCHAR2,
    SPECIALIST_AREA VARCHAR2)
AS --<< HERE
  new_cst NUMBER;
BEGIN
   SELECT CONSULTANT_IDSEQ.NEXTVAL
      INTO new_cst
      FROM DUAL;

   INSERT INTO LDS_CONSULTANT 
      (CONSULTANT_ID, CST_NAME, START_DATE, LEAVE_DATE, LOCATION, SPECIALIST_AREA)
    VALUES 
      (new_cst, p_con_name, p_con_start, p_con_end, p_con_loc, p_con_spec);
END;

但是，根本不需要SELECT INTO，您可以直接在nextval语句中使用INSERT。因此，您可以将过程简化为：

create or replace procedure hirecst
   (CST_NAME VARCHAR2,
    START_DATE DATE,
    LEAVE_DATE DATE,
    LOCATION VARCHAR2,
    SPECIALIST_AREA VARCHAR2)
AS --<< Still needed!
BEGIN
   INSERT INTO LDS_CONSULTANT 
     (CONSULTANT_ID, CST_NAME, START_DATE, LEAVE_DATE, LOCATION, SPECIALIST_AREA)
   VALUES 
     (CONSULTANT_IDSEQ.NEXTVAL, p_con_name, p_con_start, p_con_end, p_con_loc, p_con_spec);
END;

如果要从过程中返回生成的ID，则需要OUT参数：

create or replace procedure hirecst
   (CST_NAME VARCHAR2,
    START_DATE DATE,
    LEAVE_DATE DATE,
    LOCATION VARCHAR2,
    SPECIALIST_AREA VARCHAR2, 
    p_consultant_id out integer) --<< HERE
AS 
BEGIN
   -- Assign the value to the OUT parameter
   p_consultant_id := CONSULTANT_IDSEQ.NEXTVAL;

   INSERT INTO LDS_CONSULTANT 
      (CONSULTANT_ID, CST_NAME, START_DATE, LEAVE_DATE, LOCATION, SPECIALIST_AREA)
    VALUES 
      (p_consultant_id, p_con_name, p_con_start, p_con_end, p_con_loc, p_con_spec);
END;

以下是procedre的语法 -

CREATE [OR REPLACE] PROCEDURE procedure_name
    [ (parameter [,parameter]) ]

IS
    [declaration_section]

BEGIN
    executable_section

[EXCEPTION
    exception_section]

END [procedure_name];

你忘了＆＃39; IS＆＃39;关键字

following is the code-

    create or replace procedure hirecst
           (CST_NAME VARCHAR2,
            START_DATE DATE,
            LEAVE_DATE DATE,
            LOCATION VARCHAR2,
            SPECIALIST_AREA VARCHAR2)

         IS
           new_cst NUMBER;
        begin
           SELECT CONSULTANT_IDSEQ.NEXTVAL
              INTO new_cst
              FROM DUAL;
           INSERT INTO LDS_CONSULTANT (CONSULTANT_ID, CST_NAME, START_DATE, LEAVE_DATE, LOCATION, SPECIALIST_AREA)
              VALUES (new_cst, p_con_name, p_con_start, p_con_end, p_con_loc, p_con_spec);

           end;
        ;
