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.

solution:

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")

        ‘ ADDED TO MAKE oledb CONNECTION STRING DYNAMIC
        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
