在SSIS内的查询中定义源和模式名称的占位符

Question

我在SSIS包的OLE DB源中使用了以下带有硬编码数据源名称的查询，我从中提取了某些类型的行。

select * 
from mtb.dbo.TRS_Trans_For_EY_Incl_Wire_Info_20131004 AS src 
where 'TRS-' + src.Transaction_Type_Cd 
NOT IN ( 
select dtp.trans_type_cd 
from mtb_etl.dbo.tb_transaction_type AS dtp
where dtp.cust_indicator = 'I')

我的问题是如何使用标准查询（而不是硬编码查询）来提取数据，使其适用于各种数据源？

Answer 1

尤里卡!!!我找到了它！

select * 
from [dbo].[TRS_Trans_For_EY_Incl_Wire_Info_20131004]  
where 'TRS-' + [Transaction_Type_Cd] 
NOT IN ( 
select [trans_type_cd] 
from [dbo].[tb_transaction_type] 
where [cust_indicator] = 'I')
