Dynamic connection string in SSIS

This is a common problem: Use a dtsx package with dynamic database connection.

In fact there are times that you need to set connection string of database from outside of package.


Suppose that you have an OLE DB connection and set it to same database which you want to work with and named it "Connection ".

1-Use a Script Task

2-Create four variables for your connection string details

3-pass them as ReadOnlyVariables to Script Task

4- write code below on your main method:

Public Sub Main()

        Dim oledbConnectionManager As ConnectionManager
        oledbConnectionManager = Dts.Connections("Connection")

        Dim oServerName As String
        Dim oUserName As String
        Dim oInitialCatalog As String
        Dim oPassword As String

        oServerName = Dts.Variables("User::ServerName").Value.ToString()
        oInitialCatalog = Dts.Variables("User::DatabaseName").Value.ToString()
        oUserName = Dts.Variables("User::UID").Value.ToString()
        oPassword = Dts.Variables("User::Pass").Value.ToString()

        Dts.Connections("Connection").Properties("ServerName").SetValue(oledbConnectionManager, oServerName)
        Dts.Connections("Connection").Properties("InitialCatalog").SetValue(oledbConnectionManager, oInitialCatalog)
        Dts.Connections("Connection").Properties("UserName").SetValue(oledbConnectionManager, oUserName)
        Dts.Connections("Connection").Properties("Password").SetValue(oledbConnectionManager, oPassword)

        Dts.TaskResult = ScriptResults.Success
    End Sub
