我写了一个函数，看起来一切都很好，但我仍然收到错误，

以下是我的功能：

create or replace FUNCTION TRANSFERQTYBTNDATES 
(
  v_startDate IN DATE,
  v_endDate IN DATE,
  v_storeid IN NUMBER,
  v_areaid IN NUMBER
)
RETURN TransferQtyBtnDates_pkg.tt_TransferQtyBtnDates_type PIPELINED
AS
   v_temp SYS_REFCURSOR;
   v_temp_1 TT_TRANSFERQTYBTNDATES%ROWTYPE;

BEGIN
   TRUNCATE TABLE tt_TransferQtyBtnDates;

   INSERT INTO tt_TransferQtyBtnDates
      SELECT isb.ItemId ,
             SUM(isb.Quantity) TransQty  ,
             isb.ExpiryDate TransExpDates  
        FROM Issues iss
               JOIN IssuedBatches isb
                ON iss.IssueRegisterId = isb.IssueRegisterId
        WHERE iss.IssueType = 'TRANSFER ACCOUNT'
                AND iss.IssuedDate BETWEEN v_startDate AND v_endDate
                AND iss.AreaId = v_areaid
                AND iss.StoreId = v_storeid
        GROUP BY isb.ItemId,isb.Quantity,isb.ExpiryDate;

      OPEN v_temp FOR
      SELECT …

我正在做一个sql选择输出的假脱机.我有以下的SQL设置

        SET FEEDBACK OFF
        SET HEADING OFF
        SET LINESIZE 800
        SET PAGESIZE 50000
        SET TRIMSPOOL ON
        SET TERMOUT OFF
        SET ECHO OFF

问题是在select语句输出之前有空行插入假脱机文件.不确定我需要添加什么SQL设置.

任何人都可以告诉我为什么这不会执行？

set serveroutput on ;
Declare
   TYPE type_emp IS RECORD(
        emp_name employees.last_name%TYPE,
        emp_salary employees.salary%TYPE);
     rec_emp type_emp;
   due_for_a_raise CHAR(1);
begin
   SELECT last_name, salary into rec_emp
   from employees
   where employee_id = 150;
   if emp_salary > 5000 then
      due_for_a_raise := 'Y';
     else
      due_for_a_raise := 'N';
   end if;
  dbms_output.putline(last_name);
  dbms_output.putline(salary);
  dbms_output.putline(due_for_a_raise);
end;  

错误如下

我在PL/SQL中创建了一个过程,它根据主键将数据从一个表插入另一个表.我的程序工作正常,但我无法弄清楚如果主键已经存在,我将如何更新我的表MAIN列CODE_NUMBER.
实际上我希望MAIN表的行在其具有主键时获得UPDATED,并在主键不存在时从REGIONS插入数据.

DECLARE
    variable number;
    id number;
    description varchar2 (100);

    CURSOR C1 IS
        select regions.REGION_ID variable
        from regions;

BEGIN
      FOR R_C1 IN C1 LOOP
            BEGIN
                select regions.REGION_ID,regions.REGION_NAME
                into id,description
                from regions
                where regions.REGION_ID = R_C1.variable; 
                ----If exists then update otherwise insert
                INSERT INTO MAIN( ID, CODE_NUMBER) VALUES( id,description);
                dbms_output.put_line( id ||' '|| 'Already Exists');
            EXCEPTION
                WHEN DUP_VAL_ON_INDEX THEN
                dbms_output.put_line( R_C1.variable);
            END;
      END LOOP;
END; 

在我的项目中,我使用oracle作为主数据库,我遇到了解析clob的问题.所以假设我们有一个有价值的clob

   aaaaaa
   cccccc
   bbbbbb

它存储在表格测试中......

我需要写plsql程序来获取这个clob并拆分它以便我将有三个项目的数组[aaaaaa,cccccccc,bbbbbbb].

有没有可能的解决方案？

我正在尝试将a保存CLOB到变量中以执行提取等操作.我有这个代码:

DECLARE
  clob_rec CLOB;
  n_rec NUMBER:=100;
BEGIN
  SELECT LOB INTO clob_rec FROM table1 WHERE ID = 1234;
  n_rec := clob_rec.EXTRACT('//XPTO/text()', 'xmlns:XPTO').getNumVal();
END;

我想保存多个值,XML如各种变量n_rec.如何获得"对象实例(CLOB)"来执行函数或方法extract()？

有人能告诉我这段代码有什么问题.我的目标是编写一个传递员工姓名的程序,将员工表中的所有姓名和工资加载到VARRAY中,然后在屏幕上打印出姓名和工资.

CREATE OR REPLACE PROCEDURE VARRAY_Q2 
(
  PNAME IN VARCHAR2  
, PSAL OUT NUMBER  
) AS 

--declare and create cursor

CURSOR emp_cur IS
SELECT ename,sal
FROM EMP;

  TYPE varray_emp IS VARRAY(14) OF emp_Cur%ROWTYPE;

  --Creating new instance of varray
  x_varray_emp varray_emp := varray_emp();
  v_counter NUMBER := 0;

BEGIN

  x_varray_emp.EXTEND;

  FOR empRecs IN emp_Cur LOOP

  --Insert data into the varray
  x_varray_emp(v_counter) := empRecs;

  dbms_output.put_line(v_counter);

  v_counter := v_counter + 1;
  END LOOP;

  --Loop through the varray and print out all the elements
  FOR …

如何将Oracle PL/SQL包中的电子邮件发送到多个接收器？我在oracle包中有pl/sql程序,它只适用于一个接收器.我需要改进它的功能,让它可以同时向多个接收器发送电子邮件,如"To:David Festool; Peter Makita; John Dewalt".任何身体都可以帮助我,非常感谢!请提供修改后的代码.

procedure email(p_recip   in varchar2,
                p_subject in varchar2,
                p_message in varchar2) is

  c   utl_smtp.connection;
  msg varchar2(4000);

  procedure send_header(name in varchar2, header in varchar2) as
  begin
    utl_smtp.write_data(c, name || ': ' || header || utl_tcp.crlf);
  end;
begin
  --Open SMTP connection
  c := utl_smtp.open_connection('ExchangeServerName');

  -- Write SMTP header
  utl_smtp.helo(c, 'ExchangeServerName');
  utl_smtp.mail(c, 'Email@MyCompany.on.ca');
  utl_smtp.rcpt(c, p_recip);
  utl_smtp.open_data(c);
  send_header('From', '"Title" <Email@MyCompany.on.ca');
  send_header('To', p_recip);
  send_header('Subject', p_subject);
  send_header('Mime-Version', '1.0');
  send_header('Content-Type', 'multipart/mixed; boundary="DMW.Boundary.605592468"');

  -- Write MIME boundary line for the message body …

所以我触发如下

create or replace TRIGGER TWELVE_ONE 
BEFORE INSERT OR UPDATE OR DELETE
ON ORDERS
FOR EACH ROW 
DECLARE 
V_DAY VARCHAR2 (10); 
MyException exception; 

BEGIN 

SELECT TO_CHAR (SYSDATE, 'DAY') INTO V_DAY FROM DUAL; 
DBMS_OUTPUT.PUT_LINE(V_DAY); 

IF (V_DAY='SUNDAY') 
THEN 
raise_application_error(-20001, 'Today is Sunday. Order table cannot be altered'); 
end if;
END;

这应该防止UPDATE,INSERT并且DELETE如果系统一天SUNDAY.从逻辑上讲,它似乎是正确的,但不幸的是它仍然允许插入.我在这做错了什么？我正在使用SQL Developer请帮助非常感谢

我想知道我们是否有任何技术可以计算出需要为批量收集操作的LIMIT子句设置的值.例如下面,假设我们的光标有1000万条记录.我们可以为LIMIT子句设置的值是什么,以获得最佳性能.我们有什么方法可以计算它.

decalre
cursor c_emp is <some select query>

var  <variable> ;

begin
     open c_emp;
       loop
           fetch c_emp bulk collect into var limit 2;
           exit when c_emp%NOTFOUND;
      end loop;
     close c_emp;
  end;
