Question

我已经阅读了所有关于我无法找到的无关联表的帖子，但似乎没有任何东西可以帮助我（我能理解）。我有2个临时表，我需要表2只包含行 text字段包含table1中的任何一个名称。两个表之间没有直接联系。

表1示例：
的 table1.fullname
一个名字
b名称
c名称
d名称

＆＃39;主题的提取物＆＃39;表2中的列：
的主题
巴哈马食品出口市场研究报告初始电话会员名称 - 更新电话以检查进度
更新电话以检查进度名称
b名字 - 与安娜见面建议彼得 - b名字
c name-协助完成资金申请。
d name - Advice

我需要的只是表2中包含主题字段table1中任何名称的行。

我使用过类似的东西： WHERE table2.subject LIKE '%'+table1.fullname+'%' 但它不会起作用，因为我没有以任何方式加入表格。大多数帖子似乎建议使用交叉连接，但由于两个表都非常大，我不认为这是最好的方式。我认为我应该使用子查询，但无法解决如何加入它。到目前为止我的代码：

IF OBJECT_ID('tempdb.dbo.#ITA', 'U') IS NOT NULL 
DROP TABLE #ITA SELECT        *
INTO            #ITA
FROM            (select distinct fullname
from FilteredContact
Where (jobtitle LIKE 'International Trade Adviser%'))InternationalTradeAdviser;

IF OBJECT_ID('tempdb.dbo.#ITAactivity', 'U') IS NOT NULL 
DROP TABLE #ITAactivity SELECT        *
INTO            #ITAactivity
FROM            (SELECT distinct     FilteredAppointment.activityid as ActivityID, Filteredccx_project.ccx_customerid AS CompanyID,  Filteredccx_project.ccx_projectnumber AS ProjectNumber,
                                CONVERT(varchar, FilteredAppointment.scheduledstart, 103) AS ConvertedTime, 
                                FilteredAppointment.actualdurationminutes, FilteredAppointment.actualdurationminutes / 60 AS Hours, FilteredAppointment.actualdurationminutes % 60 AS Minutes,
                                'International Trade Adviser' As TypeOfService
                FROM            FilteredAppointment INNER JOIN
                Filteredccx_project ON FilteredAppointment.regardingobjectid = Filteredccx_project.ccx_projectid
                WHERE        (FilteredAppointment.statecode = 1) AND (FilteredAppointment.subject LIKE '%'+#ITA.fullname+'%') AND
                (Filteredccx_project.ccx_programme IN ('04D0B1DF-FD36-E611-8870-005056A52209','14286237-FE36-E611-8870-005056A52209')) AND
                Filteredccx_project.ccx_projectstatus IN(803080000,803080001) AND 
                Filteredccx_Project.ccx_runningtotal>=12)ITAactivities;

我尝试在WHERE子句中使用子查询但产生错误消息，因为它返回的行数超过1行。

Answer 1

由于您说您只想要包含全名的记录，因此您也可以在exists - 子句中使用where。

为此，请更换部件

AND (FilteredAppointment.subject LIKE '%'+#ITA.fullname+'%')

用这个

AND exists (select 1
              from #ITA it
             where FilteredAppointment.subject like '%' + it.fullname + '%')

最终的插入看起来像这样：

SELECT *
  INTO #ITAactivity
  FROM (SELECT distinct
               FilteredAppointment.activityid as ActivityID,
               Filteredccx_project.ccx_customerid AS CompanyID,
               Filteredccx_project.ccx_projectnumber AS ProjectNumber,
               CONVERT(varchar, FilteredAppointment.scheduledstart, 103) AS ConvertedTime,
               FilteredAppointment.actualdurationminutes, FilteredAppointment.actualdurationminutes / 60 AS Hours, FilteredAppointment.actualdurationminutes % 60 AS Minutes,
               'International Trade Adviser' As TypeOfService
          FROM FilteredAppointment
                 INNER JOIN
               Filteredccx_project ON FilteredAppointment.regardingobjectid = Filteredccx_project.ccx_projectid
         WHERE (FilteredAppointment.statecode = 1)
           AND (Filteredccx_project.ccx_programme IN ('04D0B1DF-FD36-E611-8870-005056A52209', '14286237-FE36-E611-8870-005056A52209'))
           AND Filteredccx_project.ccx_projectstatus IN (803080000, 803080001)
           AND Filteredccx_Project.ccx_runningtotal >= 12
           AND exists (select 1
                         from #ITA it
                        where FilteredAppointment.subject like '%' + it.fullname + '%'))ITAactivities;

Answer 2

这种动态技术可能很有用：

Declare @FullNames as nvarchar(max)
Declare @Sql as nvarchar(max)

select @FullNames = 
    stuff((
        select distinct ' or subject like ''%' + [fullname] + '%'''
        from t1
        for xml path('')
    ),1,3,'') as x

set @Sql = 'SELECT        *
            INTO            #ITAactivity
            FROM            (SELECT distinct     FilteredAppointment.activityid as ActivityID, Filteredccx_project.ccx_customerid AS CompanyID,  Filteredccx_project.ccx_projectnumber AS ProjectNumber,
                            CONVERT(varchar, FilteredAppointment.scheduledstart, 103) AS ConvertedTime, 
                            FilteredAppointment.actualdurationminutes, FilteredAppointment.actualdurationminutes / 60 AS Hours, FilteredAppointment.actualdurationminutes % 60 AS Minutes,
                            ''International Trade Adviser'' As TypeOfService
            FROM            FilteredAppointment INNER JOIN
            Filteredccx_project ON FilteredAppointment.regardingobjectid = Filteredccx_project.ccx_projectid
            WHERE        (FilteredAppointment.statecode = 1) AND (FilteredAppointment.subject LIKE ''%''+#ITA.fullname+''%'') AND
            (Filteredccx_project.ccx_programme IN (''04D0B1DF-FD36-E611-8870-005056A52209'',''14286237-FE36-E611-8870-005056A52209'')) AND
            Filteredccx_project.ccx_projectstatus IN(803080000,803080001) AND 
            Filteredccx_Project.ccx_runningtotal>=12)ITAactivities AND (' + @FullNames + ')'

exec(@Sql)
