@Florida

Duno your purpose. But just give you the result from my platform. (2 SQL server in the network)

whereismyid(到处找ID)
3. you should modify Diff to DateDiff
Declare @temp Table(Code Char(3),EffectiveDate Datetime,Rate Decimal(12,9))
Insert Into @temp(Code,EffectiveDate,Rate)
Select Code,EffectiveDate,Rate
From [LinkedServer].[testdb].[dbo].[VTABLE]
Where DateDiff(Day,EffectiveDate,getDate())<1

sELECT * FROM @temp

-- VTABLE records:
Code EffectiveDate Rate DDescription
cd1 2009-01-01 00:00:00.000 100 sql linked to sql
cd2 2009-01-02 00:00:00.000 200 sql linked to sql
cd3 2009-01-03 00:00:00.000 300 sql linked to sql
cd4 2009-01-21 00:00:00.000 400 sql linked to sql

-- Result:
cd4 2009-01-21 00:00:00.000 400.000000000

    本文发表在 rolia.net 枫下论坛因对ORACLE不熟而且没法测试，请用ORACLE和SQL SERVER的朋友们帮个忙，测一下下面的CASE：

    目的： 在ORACLE LINKED SERVER上查询一个表或VIEW，把当天数据捣到sql server的表中

    1. ORACAL上有个数据库XXX包含这样的VTABLE：
    Code Varchar2(3)
    EffectiveDate Datetime
    Rate Numeber(12,9)
    DDescription Varchar2(100)
    输几条记录做测试用 ,请用不同日期,其中至少一个用当前日期

    2. 在SQL SERVER 2005 上建立ORACLE LINKED SERVER，名称就叫ORALINKEDSrv好了

    3. 在 SQL SERVER 2005上做下面的QUERY:

    Declare @temp Table(Code Char(3),EffectiveDate Datetime,Rate Decimal(12,9))

    Insert Into @temp(Code,EffectiveDate,Rate)
    Select Code,EffectiveDate,Rate
    From ORALINKEDSrv.XXX.SYSOWNER.VTABLE -- SYSOWNER请改用实际OWNER名
    Where Diff(Day,EffectiveDate,getDate())<1

    sELECT * FROM @temp

    Go


    4.假如3不行，改用OPENQUERY -- 对其中ORACLE的QUERY可能有错，请修改

    Declare @temp Table(Code Char(3),EffectiveDate Datetime,Rate Decimal(12,9))

    Insert Into @temp(Code,EffectiveDate,Rate)
    Select Code,EffectiveDate,Rate
    From OpenQuery(ORALINKEDSrv,'Select Code,trunc(EffectiveDate)=date(),Rate From XXX.SYSOWNER.VTABLE')


    SELECT * FROM @temp

    Go

    请把3和4的结果贴在这里或者请PM，多谢！更多精彩文章及讨论，请光临枫下论坛 rolia.net

    • 1. Date filter condition. In Oracle, it should be EffectiveDate >=TRUNC(Sysdate -1) or likewise. 2. Not sure what’s your goal, query (or join query) data in Oracle database from sql server, or transfer data from Oracle? -deep_blue(BLUE); 2009-1-21 (#4997085@0)
