如何以编程方式导入/导出SQL数据库表

Question

I am trying to import all of a Database's information to another Database just as I would when doing it with the user interface.

I tried to do it with a large .SQL file generated by one of my custom inhouse programs, but the server runs out of memory due to a 300MB .sql file.

How can I utilize SQL Server's Import feature via code in VB.Net?

You can try to use other methods as data replications between servers or another "more Admin" approcach, but if you want to do it programatically you can create a DTS (data transformation package), then use a scheduler like quartz and execute your DTS with the schedule you need it.

Dim dtsp As New DTS.Package
    dtsp.LoadFromSQLServer _
        ServerName:="MyServer", _
        ServerUserName:="MyUserID", _
        ServerPassword:="MyPassword", _
        PackageName:="DTSDemo"
    dtsp.Execute

take a look to the reference this may help you out.

That only will work on previous versions to SQL 2012.

as an alternative you may want to call a SSIS package so take a look to this tutorial practically the logic is the same whatever you decide to use a DTS or a SSIS package.
