Connect to SQL database inside Script Task in SSIS

问题

Inside of a Script Task in SSIS, I need to make a call to an SQL database. I have a connection string that was created when I added the database to the data sources folder, however now I'm not sure how to reference it inside the C# code. I know how to do this in the code behind of an ASP website, however it seems that SSIS should have a more direct method.

EDIT

This line of code actually winds up throwing an exception:

sqlConn = (System.Data.SqlClient.SqlConnection)cm.AcquireConnection(Dts.Transaction);

It reads: "Unable to cast COM object of type 'System._ComObject' to class type 'System.Data.SqlClient.SqlConection.'"

回答1:

you cant use the configurations from a connection manager from inside a script task like: conectionManager1.exceuteSQLStatment(...)

once you are "inside" the script task you need to access the CM like a variable:

ConnectionManager cm;
System.Data.SqlClient.SqlConnection sqlConn;
System.Data.SqlClient.SqlCommand sqlComm;

cm = Dts.Connections["conectionManager1"];

sqlConn = (System.Data.SqlClient.SqlConnection)cm.AcquireConnection(Dts.Transaction);
sqlComm = new System.Data.SqlClient.SqlCommand("your SQL Command", sqlConn);
sqlComm.ExecuteNonQuery();

cm.ReleaseConnection(sqlConn);

回答2:

You must check the privider of the connection that your are trying to instantiate.

You can't cast a OleDb.OleDbConnection connection as a SQLClient.SQLConnection, the parameters are different.
