错误（9,1）：PLS-00428：在创建存储过程时，此 SELECT 语句中需要一个 INTO 子句

Question

我创建了一个 SP，但是在编译时出现错误

错误（9,1）：PLS-00428：此 SELECT 语句中应有一个 INTO 子句

下面是SP

CREATE OR REPLACE PROCEDURE FIP_VALID_TBL_TRANSMEDIA 
 (
   POUTMSG OUT VARCHAR2
  )

 AS 
BEGIN

表格说明

           Name            Null Type           
           --------------- ---- -------------- 
           SPAN_ID              NVARCHAR2(100) 
           MAINT_ZONE_CODE      NVARCHAR2(100) 
           UPDATED_DATE         DATE           
           UPDATED_BY           NVARCHAR2(100)

Answer 1

我只想在这个过程中插入

您可以只使用insert ... select [语法]：

CREATE OR REPLACE PROCEDURE FIP_VALID_TBL_TRANSMEDIA 
 (
   POUTMSG OUT VARCHAR2
  )

 AS 
BEGIN

 INSERT INTO TBL_VLD_FIBERINV_DATA (SNAP_ID, MAINT_ZONE_CODE)
 SELECT TO_CHAR(sp.RJ_SPAN_ID), TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE)
 ...
 MINUS
 SELECT TO_CHAR(sp.RJ_SPAN_ID), TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE)
 ...

您不需要带有 MINUS 的 distinct；并且列别名没有用。

或者，如果您想设置其他列，并且它们还没有默认，您可以在查询部分包含这些值 - 这里使用系统时间和当前用户：

 INSERT INTO TBL_VLD_FIBERINV_DATA (SNAP_ID, MAINT_ZONE_CODE, UPDATED_DATE, UPDATED_BY)
 SELECT TO_CHAR(sp.RJ_SPAN_ID), TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE), SYSDATE, USER
 ...
 MINUS
 SELECT TO_CHAR(sp.RJ_SPAN_ID), TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE), SYSDATE, USER
 ...

---

你需要执行这个过程，它才能真正做任何事情；只是创建或编译它不会导致其中的代码（即插入）运行。您可以从一个简单的匿名块中做到这一点：

DECLARE
 OUTMSG VARCHAR2(4000);
BEGIN
 FIP_VALID_TBL_TRANSMEDIA (POUTMSG => OUTMSG);
END;
/

您必须声明并传递一个变量以匹配过程的形式参数，即使您当前没有填充它。 （希望您不打算捕获异常并将异常消息放入该变量中......）

在目标表中使用nvarchar2 似乎有点奇怪，即使用户ID 的大小也为100；并让to_char() 调用似乎已经是字符串的东西。你使用的是the to_char(char) function，它总是返回varchar2，所以把它放到nvarchar2中似乎很奇怪......

Answer 2

在此过程中，您正在执行一个查询，但您没有将该查询的结果放在任何地方。我建议重写为：

CREATE OR REPLACE PROCEDURE FIP_VALID_TBL_TRANSMEDIA(POUTMSG OUT VARCHAR2)
AS 
BEGIN
  SELECT SPAN_ID || MAINT_ZONE_CODE
    INTO POUTMSG  -- puts result of query into POUTMSG

                          TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE) AS MAINT_ZONE_CODE
            from  APP_FTTX.span@SAT sp
            WHERE LENGTH(sp.RJ_SPAN_ID) = 21 AND
                  (sp.RJ_SPAN_ID LIKE ('%SPN%') OR
                   sp.RJ_SPAN_ID LIKE ('%SPQ%') OR
                   sp.RJ_SPAN_ID LIKE ('%SPR%') OR
                   sp.RJ_SPAN_ID LIKE ('%SPS%')) AND
                  (sp.RJ_SPAN_ID LIKE ('%_BU') OR
                   sp.RJ_SPAN_ID LIKE ('%_MP')) AND
                   sp.INVENTORY_STATUS_CODE = 'IPL' AND
                   sp.RJ_MAINTENANCE_ZONE_CODE = 'INMUNVMB01' AND
                  (sp.RJ_INTRACITY_LINK_ID NOT LIKE ('%\_9%') ESCAPE '\' OR 
                   sp.RJ_INTRACITY_LINK_ID IS NULL)                                        
          MINUS
          SELECT distinct TO_CHAR(sp.RJ_SPAN_ID) AS SPAN_ID,
                          TO_CHAR(sp.RJ_MAINTENANCE_ZONE_CODE) AS MAINT_ZONE_CODE
            from  APP_FTTX.span@SAT sp
            INNER JOIN APP_FTTX.transmedia@SAT tm  -- transmedia added
              on sp.RJ_SPAN_ID = tm.RJ_SPAN_ID
            WHERE length(sp.RJ_SPAN_ID) = length(tm.RJ_SPAN_ID) and
                  sp.RJ_MAINTENANCE_ZONE_CODE = tm.RJ_MAINTENANCE_ZONE_CODE and
                  sp.INVENTORY_STATUS_CODE = tm.INVENTORY_STATUS_CODE AND
                  LENGTH(sp.RJ_SPAN_ID) = 21 AND
                  (sp.RJ_SPAN_ID LIKE ('%SPN%') OR
                   sp.RJ_SPAN_ID LIKE ('%SPQ%') OR
                   sp.RJ_SPAN_ID LIKE ('%SPR%') OR
                   sp.RJ_SPAN_ID LIKE ('%SPS%')) AND
                  (sp.RJ_SPAN_ID LIKE ('%_BU') OR
                   sp.RJ_SPAN_ID LIKE ('%_MP')) AND
                   sp.INVENTORY_STATUS_CODE = 'IPL' AND
                   sp.RJ_MAINTENANCE_ZONE_CODE = 'INMUNVMB01' AND
                  (sp.RJ_INTRACITY_LINK_ID NOT LIKE ('%\_9%') ESCAPE '\' OR 
                   sp.RJ_INTRACITY_LINK_ID IS NULL);
END FIP_VALID_TBL_TRANSMEDIA;
