Package Validation Error

I'm trying to use a foreach loop container to import several excel files into a table, I specified the folder and the files I'm going to use (*.xls), after that I created a path variable then I went to the excel source connection and in the "Expression" property I selected the variable. I created the foreach container but, the excel source's connectionString only shows Provider=Microsoft.Jet.OLEDB.4.0; , so it means it's not taking the variable value. What can I do to solve that? Note: I'm using SQL Server 2012 ADDITIONAL INFORMATION: Error at Data Flow Task [Excel Source [20]]: SSIS Error

Best Practise to populate Fact and Dimension Tables from Transactional Flat DB

由 断了今生、忘了曾经 提交于 2019-12-06 03:48:19
问题 I want to populate a star schema / cube in SSIS / SSAS. I prepared all my dimension tables and my fact table, primary keys etc. The source is a 'flat' (item level) table and my problem is now how to split it up and get it from one into the respective tables.

Thanks, alexl 回答1: For a start, it depends on whether you want to do
