Connect to previous months table


hi folks

i have database contains monthly tables contain sales data

i.e tables in database have name structure follows 

  • sales_2012_11
  • sales_2012_12
  • sales_2013_01
  • sales_2013_02
  • sales_2013_03

what best way connect previous months sales table? because needs be scheduled package, want avoid having update table name in select statement in source connection manager. 

any suggestions welcome

stevo



if data in different tables make the source table (or complete source query) dynamic.

create ssis variable type string , add expression. like:

"sales_" +  (dt_wstr,4)datepart("yyyy", dateadd("mm", -1, getdate())) + "_" + right("0" + (dt_wstr,2)datepart("mm", dateadd("mm", -1, getdate())), 2)


now can use variable in ole db source

please mark post answered if answers question | ssis blog: http://microsoft-ssis.blogspot.com | twitter
