import from Access to SQL, not knowing the table format

I need to import few tables from MS Access to MS SQL but the table structure in Access is always different, as I would like the destination table in SQL to be.

Therefore I would like that a table would be created in SQL at runtime, according to the structure the Access table accessed has.

You can't do this using a data-flow because for these you need to know the metadata of the source and destination at design-time and according to your post, you don't know that!

I don't know much about Access. Is there a way of interrogating the metadata at design-time? If so you could get that metadata (hopefully using an Execute SQL Task) and use that to build your data-flow programatically at runtime. That's a difficult thing to do though. If you really want to go down this route then there's some stuff in BOL to help you.

|||OK, got the point.
Just to be clear, I wuold like to do something like

select * into <table destination> from <table source>

But I cannot because the source is Access, the destination is SQL Server 64 bit and there is no MS Jet driver for 64 bit.

Anybody has a good idea?|||

The only way to do this with a SELECT...INTO... is to set the Access mdb up as a linked server.

You can still run this on a 64 bit machine, just call it through the 32 bit dtexec, see the Program Files x86 folder.

I think your bigger issue is the lack of metadata up front, as Jamie points out.

|||i'm not sure about this, but i think you can use the script task to determine the access table schema. then, you could use this schema information to dynamically create the sql server table.
