December 15, 2008

Hi all!

Some time ago, a friend of mine, Horita, told me about a project whose owner asked people who liked his software to send him a postcard. I liked the idea and yesterday, while cooking the 2.0.2 release with Josh Cooley, I told him about this idea and he also liked it.

So, if you like Npgsql you can send us a postcard. Here are the addresses:

UUID datatype and COPY IN/OUT support added to cvs

October 03, 2007

Hi all! It was just added support to uuid datatype in cvs head. This type will be available in next Postgresql release 8.3. Thanks to David Bachmann for his patch! You can get more info about this patch in this mailing list post . Also was added support for copy in and copy out operations. Now, users can provide streams which can be copied directly to and from Postgresql tables! Thanks to Kalle Hallivuori for providing a patch! Thanks to Truviso for giving support to Kalle. More info about that including a demo and ready to use compiled Npgsql.dll versions can be found here . That's it! As soon as we get more features added, I will post info about them here.

Npgsql Tips: Using " in (...)" queries with parameters list and "any" operator

May 12, 2009

Hi, all! We have received some users questions about how to send a list of values to be used in queries using the "in" operator. Something like: select foo, bar from table where foo in (blah1, blah2, blah3); Npgsql supports array-like parameter values and the first idea to have this working would try to use it directly: NpgsqlCommand command = new NpgsqlCommand("select * from tablee where field_serial in (:parameterlist)", conn); ArrayList l = new ArrayList(); l.Add(5); l.Add(6); command.Parameters.Add(new NpgsqlParameter("parameterlist", NpgsqlDbType.Array | NpgsqlDbType.Integer)); command.Parameters[0].Value = l.ToArray(); NpgsqlDataReader dr = command.ExecuteReader(); but unfortunately this won't work as expected.

Using Entity Framework 6 with Npgsql 2.1.0

February 17, 2014

UPDATE (2014-02-20): I created a new post explaining how to get Npgsql 2.1.0. Although this post is about EF 6, I'd like to talk about our current situation to support both EF 6 and EF4.x which explain why there are some subtle changes between EF 4.x and EF 6.x App.config settings. Support for EF versions 4.x and 6.x Sometime after we started to work on Npgsql 2.1.0, we started to add code to support EF6 and decided to reorganize our Entity Framework support code. Shay created a pull request to organize this change and isolate the EF code out of core Npgsql code. The result was the creation of two separated assemblies: Npgsql.EntityFramework.dll for EF6 and above; Npgsql.EntityFrameworkLegacy.dll for EF4.x. Only when using Npgsql with EF6 you will need to reference Npgsql.EntityFramework.dll assembly. This is needed because the EF ...
