问题 Most of my company uses powercenter informatica for Extract-Transform-Load type data move jobs between databases. However project I am on has a big custom Perl job with some Java thrown in for good measure to move data and trigger some other updates.

问题 I have this new challenge to load ~100M rows from an Oracle database and insert them in a remote MySQL database server.

问题 I have populated a list in C# script and assigned its value to SSIS object variable. Then I used that object variable to execute some SQL query by looping through For each do enumerator. I tried doing this by Foreach ado enumerator but getting error X variable doesn't contain a valid data object. Can anybody provide any inputs. 回答1: Youre using a list. Not a recordset and therefore you need to enumerate over a variable. If you want to use ADO Recordset, you need to fill a datatable instead.
