PLS-00306: 调用 'PUT_LINE' 时参数的数量或类型错误

Question

这是我第一次尝试编写 Oracle 过程，但我收到一个错误（显示在问题标题中）集中在 DBMS_OUTPUT.PUT_LINE 行。

我在网上看到它只能返回 VARCAHR2 列，所以我投射了仅有的两个正在访问的非 VARCHAR2 列，但我仍然收到错误。当我尝试直接在 oracle SQL Developer.运行中运行时发生此错误。

CREATE OR REPLACE PROCEDURE LOGGING_PRC 
(
  STARTDATE_IN IN VARCHAR2,
  ENDDATE_IN IN VARCHAR2,
  NAMES_IN IN VARCHAR2, 
  MODS_IN IN VARCHAR2, 
  LOGS_IN IN VARCHAR2,

  ID_OUT OUT VARCHAR2,
  NAME_OUT OUT VARCHAR2,
  MODULE_OUT OUT VARCHAR2,
  ENTRYDATE_OUT OUT VARCHAR2,
  STATUS_OUT OUT VARCHAR2,
  TYPE_OUT OUT VARCHAR2
)  
  AS 
BEGIN
    SELECT
    CAST(ID_LOG AS VARCHAR2(16)),
     APNAME,
     APPMOD,
     CAST(ENTRYDATE AS VARCHAR2(30)),
     APPSTATUS,
     LOGTYPE
  INTO 
      ID_OUT,
      NAME_OUT,
      MODULE_OUT,
      ENTRYDATE_OUT,
      STATUS_OUT,
      TYPE_OUT
   FROM 
     BASE          
   WHERE     
     ENTRYDATE > STARTDATE_IN AND
     ENTRYDATE  < ENDDATE_IN AND
     (NAMES  =  NAMES_IN OR NAMES_IN IS NULL) AND
     (MODS = MODS_IN OR MODS_IN IS NULL) AND
     (LOGS = LOGS_IN  OR LOGS_IN IS NULL);      
  RETURN;
DBMS_OUTPUT.PUT_LINE(ID_OUT, NAME_OUT, MODULE_OUT, ENTRYDATE_OUT, STATUS_OUT, TYPE_OUT);
END LOGGING_PRC;

有人看到我哪里有错误代码吗？

Answer 1

DBMS_OUTPUT.PUT_LINE定义如下

procedure put_line(a varchar2);

所以，它只接受一个输入参数。

如果您需要打印多个字段的值，您需要将它们连接成一个varchar2；你可以试试：

DBMS_OUTPUT.PUT_LINE(ID_OUT || ',' || NAME_OUT || ',' || MODULE_OUT || ',' || ENTRYDATE_OUT || ',' || STATUS_OUT || ',' || TYPE_OUT);
