如何使用SSIS将具有不同标头的多个csv文件导入数据库？

Question

I am writing a SSIS package to import multiple files in a folder with variation in the columns into a database. But cant find solution as one table has 12 columns and other 2 columns and while setting up the data flow not getting how to make the tables dynamic irrespective of the columns. Any other solution better than SSIS is also appreciated

See the discussion in this link: Can SSIS import data from multiple files to multiple tables in loop?

You can use BCP or Bulk Insert to load files into different table.

From you description:

database has fix number of tables which are same in every database, but the 18 tables have different columns.... for example: DB1 has [db1].[T1],[db1].[T2] DB2 has [db2].[T1],[db2].[T2] So [db1].[T1] structure is same as [db2].[T1] but [db1].[T1] has diff structure than [db1].[T2]

What you need to do is to store File-Table mapping in a control table and then use Script Task to concatenate dynamic SQL Statement passed to Server.
