SSIS package - set oledb connections at runtime


SSIS oledb connection manager does't allow user to connect to different oledb servers. If we store oledb connection sting in Config file then it will accepts server name, InitialCatalog and username. But it wont accept password. The is because oledb connection manager has not exposed the oledb password property. To over come this problem we have to override the OLEDB connection manager itself. So that it accepts connections to different oledb servers.


Public Sub Main()
Dim vars As Variables

Dim oledbConnectionManager As ConnectionManager
oledbConnectionManager = Dts.Connections("<oledb connection name>")

' ADDED TO MAKE oledb CONNECTION STRING DYNAMIC
Dim oServerName As String
Dim oUserName As String
Dim oInitialCatalog As String
Dim oPassword As String

Dts.VariableDispenser.LockOneForWrite("oServerName", vars)
oServerName = vars("oServerName").Value.ToString().Trim()
vars.Unlock()

Dts.VariableDispenser.LockOneForWrite("oInitialCatalog", vars)
oInitialCatalog = vars("oInitialCatalog").Value.ToString().Trim())
vars.Unlock()

Dts.VariableDispenser.LockOneForWrite("oUserName", vars)
oUserName = vars("oUserName").Value.ToString().Trim())
vars.Unlock()

Dts.VariableDispenser.LockOneForWrite("oPassword", vars)
oPassword = vars("oPassword").Value.ToString().Trim()) ' 
vars.Unlock()

Dts.Connections("<oledb connection name>").Properties("ServerName").SetValue(oledbConnectionManager, oServerName)
Dts.Connections("<oledb connection name>").Properties("InitialCatalog").SetValue(oledbConnectionManager, oInitialCatalog)
Dts.Connections("<oledb connection name>").Properties("UserName").SetValue(oledbConnectionManager, oUserName)
Dts.Connections("<oledb connection name>").Properties("Password").SetValue(oledbConnectionManager, oPassword )

Dts.TaskResult = Dts.Results.Success

End Sub

UML - Association, Aggregation, Composition, Generalization, Specialization, Realization and Dependency

Association Association is a simple relationship between two classes. For example A relationship between Professor Class and Student class is known as Association. Both Classes can exist without each other, so Professor and Student are two independent classes. In this kind of relationships there will not be any owner class. Both classes have their own life cycle. UML Notation:     Aggregation Aggregation is a special type of Association. It is known as “Has-A” relationship. For example A Department class can contain Professor Class. Here Department class is owner class. Here in this relationship even after deleting Department class, Professor Class can exits. UML Notation: Composition Composition is a special type of Aggregation. It is known as “Is-A” relationship. For example A University Class has many Department class. Here University and Department objects are dependent on each other. If we delete Univ...
