这是通过将 3 个输入参数传递给函数创建的包

CREATE OR replace PACKAGE "PKG_CAMPAIGN_EMAIL_QTY"
AS
  FUNCTION Getcampaignoutgoingemailqty(
    tablename     IN VARCHAR2,
    ActivatedDate IN DATE,
    CompletedDate IN DATE)
  RETURN NUMBER;
END pkg_campaign_email_qty;

/

这是获取计数的查询

SELECT
(
pkg_campaign_email_qty.Getcampaignoutgoingemailqty(
      9142632263013677974, 
      To_date('20/10/2015', 'DD/MM/YYYY'), 
      To_date('30/11/2015', 'DD/MM/YYYY')
      ) 
) AS
email
FROM   dual;

获取 ORA-00933: SQL 命令未在 oracle 中正确结束

这是包裹体

CREATE OR REPLACE PACKAGE BODY "PKG_CAMPAIGN_EMAIL_QTY" as
FUNCTION getCampaignOutgoingEmailQty(tableName IN VARCHAR2 ,ActivatedDate DATE,CompletedDate DATE) RETURN NUMBER IS
OutgoingEmailQuantity NUMBER;
  begin
        EXECUTE IMMEDIATE 'select NVL(COUNT(1),0) from campaign_'||tableName||'
            join flat_interactions out_email on campaign_'||tableName||'.fullname=out_email.o_parent_id and  out_email.N9135700037713613964=9135706250013621563 and out_email.D9135699928113613119 between TO_DATE(''ActivatedDate'',''MM/dd/YYYY'') and TO_DATE(''CompletedDate'',''MM/dd/YYYY'')' INTO OutgoingEmailQuantity;
RETURN OutgoingEmailQuantity ;
   EXCEPTION
      WHEN OTHERS THEN
       RETURN 0;
  end getCampaignOutgoingEmailQty;
end PKG_CAMPAIGN_EMAIL_QTY;

我不知道这是否是您看到的错误的原因，但功能代码存在问题 - 如果您查看执行立即，您有

'<snip> and out_email.D9135699928113613119 between TO_DATE(''ActivatedDate'',''MM/dd/YYYY'') and TO_DATE(''CompletedDate'',''MM/dd/YYYY'')'

这意味着，传入这些参数，您最终将尝试执行以下 sql 语句：

select NVL(COUNT(1),0)
from   campaign_9142632263013677974
       join flat_interactions out_email on campaign_9142632263013677974.fullname = out_email.o_parent_id 
                                           and out_email.N9135700037713613964 = 9135706250013621563
                                           and out_email.D9135699928113613119 between TO_DATE('ActivatedDate','MM/dd/YYYY') 
                                           and TO_DATE('CompletedDate','MM/dd/YYYY');

因此，您正在尝试将字符串“ActivatedDate”和“CompletedDate”转换为日期，而这些日期显然不是日期。

而不是这样做，我会使用绑定变量，例如：

create or replace package body pkg_campaign_email_qty
as
  function getcampaignoutgoingemailqty(tablename in varchar2 ,activateddate date,completeddate date)
  return number
  is
    outgoingemailquantity number;
  begin
    execute immediate 'select NVL(COUNT(1),0)'||chr(10)||
                      'from   campaign_'||tablename||chr(10)||
                      '       join flat_interactions out_email on campaign_'||tablename||'.fullname=out_email.o_parent_id'||chr(10)||
                      '                                           and out_email.N9135700037713613964=9135706250013621563'||chr(10)||
                      '                                           and out_email.D9135699928113613119 between :ActivatedDate and :CompletedDate' into outgoingemailquantity using activateddate, completeddate;
    return outgoingemailquantity;
  exception
    when others then
      return 0;
  end getcampaignoutgoingemailqty;
end pkg_campaign_email_qty;
/

注意未经测试，因为您没有提供任何表定义。

顺便说一句，对于您的调用查询，外括号是不必要的，我会删除它们，因此您的查询将变为：

SELECT pkg_campaign_email_qty.Getcampaignoutgoingemailqty(9142632263013677974, 
                                                          To_date('20/10/2015', 'DD/MM/YYYY'), 
                                                          To_date('30/11/2015', 'DD/MM/YYYY')) email
FROM   dual;

您在动态 sql 中使用了错误的日期。

我将为此使用绑定：

  EXECUTE IMMEDIATE 
    'select NVL(COUNT(1),0) 
     from campaign_'||tableName||'
     join flat_interactions out_email on 
        campaign_'||tableName||'.fullname=out_email.o_parent_id and  
        out_email.N9135700037713613964=9135706250013621563 and 
        out_email.D9135699928113613119 between :ActivatedDate and :CompletedDate' 
  INTO OutgoingEmailQuantity 
  USING ActivatedDate, CompletedDate;

你想做的事情更难遵循：

  EXECUTE IMMEDIATE 
    'select NVL(COUNT(1),0) 
     from campaign_'||tableName||'
     join flat_interactions out_email on 
        campaign_'||tableName||'.fullname=out_email.o_parent_id and  
        out_email.N9135700037713613964=9135706250013621563 and 
        out_email.D9135699928113613119 between 
          TO_DATE('||to_char(ActivatedDate,'MM/dd/YYYY')||',''MM/dd/YYYY'') 
          and 
          TO_DATE('||to_char(CompletedDate,'MM/dd/YYYY')||',''MM/dd/YYYY'')' 
  INTO OutgoingEmailQuantity;
