ConnectionManager.SetQualifier Method
Changes a qualifier on the connection manager after the connection manager has been created but before it is used in a running package.
Namespace: Microsoft.SqlServer.Dts.Runtime
Assembly: Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)
The SetQualifier method modifies the value of the CreationName property by appending the fully-qualified provider name to the type of the connection manager. For example, the SetQualifier method has modified the name of the following ADO.NET connection manager by appending the fully-qualified provider name to "ADO.NET":
ADO.NET:System.Data.OleDb.OleDbConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
This method can be used to change the qualifier only during design time. SetQualifier cannot be called on the connection manager during package execution.
