Connecting to SQL Server from Windows using FDW

От

Hi,

I need to create a linked server between 2 Windows servers. In one I've PostgreSQL with admin privileges and in the other MS SQL with only read access.

I need to create a view (or a foreign table?) in PostgreSQL from a table in MS SQL in another server. The table in the MS SQL is constantly growing and I need on-the-fly access to the data.

After some web search I found GeoffMontee's Github, but I don't know how to install it on Windows...

Is there anyone how already did something like this and could help me out..?
 
Thanks in advance!

Kind regards,

Seems like it is an open issue:

Perhaps this link may help:
https://www.mssqltips.com/sqlservertip/3663/sql-server-and-postgresql-foreign-data-wrapper-configuration--part-3/

The only caveat I see offhand is the use of the 'sa' account, but I can't vouch for that being a required mapping.

Cheers,
John

Hi John,

Thanks, but I already saw that link. The problem is to installing the tds_fwd extension on postgres. And I don't know how to (never tried) compile it...

What comes with postgres by default is the postgres fdw, that allow to link 2 different postgres servers, but in this case that doesn't help me.

Sorry Ivo, my bad - I managed to gloss over the salient point for your issue in this link - you're on Windows, his Postgres was on Linux!

Compiling an extension on Windows, last time I tried many moons ago was unfortunately not successful, which involved compiling the whole pg source tree via MinGW.

Hazarding a thought - although it's discontinued, it might be worth checking out Windows Subsystem for UNIX-based Applications (SUA):

But I suspect anything you managed to compile with that would still be incompatible with your pg instance...

Beyond that, perhaps the gurus here have some sage advice...
