I have been using C# to write a concrete provider implementation for our product for different databases. W/out getting into details, one of the columns is of byte array type (bytea in postgres - due to the preferences bytea was chosen over blob). The only problem, is that it does not return same value that was inserted. When I insert Int32 ("0") I get 8 [92 and 8x 48] (instead of [0,0,0,0]). I need a performance wise solution, that will return pure bytes I have inserted, instead of ASCII representation of value "0" on 8 bytes. I am using Npgsql to retrive data. If someone knows solution for c

I am attempting to set up my application to use Entity Framework with PostgreSQL, but I have run up against a problem. I have added Npqsql via nuget, and added the following provider factory to web.config : <system.data> <DbProviderFactories> <add name="Npgsql Data Provider" invariant="Npgsql" description=".Net Framework Data Provider for Postgresql Server" type="Npgsql.NpgsqlFactory, Npgsql, Version=2.0.12.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7" /> </DbProviderFactories> </system.data> With the connection string: <add name="MyDb" providerName="Npgsql" connectionString="Server

I succeeded in accessing an existing postgresql dbase by using npgsql directly. I used for this: PostgreSQL 9.0.10 (32 bit) Visual Studio 2015 Community (64 bit) NpgSql 2.2.5 (through Manage Nuget Packages) The dbase however has 25+ tables and 400+ columns and such my intention is to to use entity framework + .ADO.net Entity Data Model to avoid having to code access to all columns. I searched and tried everything on this site, npgsql site http://www.npgsql.org/doc/ddex.html , ... but I I did not succeeded in generating an .ADO.net Entity Data Model because postgresql does not appear in Data

While using a PostgreSQL database with Entity Framework on Mono using the packages Npsql and Npsql.EntityFramework I get an exception while trying to run Code First migrations from a Console app. The connection does work in the app and the database can be CRUD'ed programmatically. The Context class looks as follows: public class ZkContext : DbContext, IZkContext { public ZkContext() : base("ZkTestDatabaseConnection") { } protected override void OnModelCreating(DbModelBuilder modelBuilder) { // PostgreSQL uses schema public by default. modelBuilder.HasDefaultSchema("public"); } public IDbSet

I have a class of range public class avl_range { public long start { get; set; } public long end { get; set; } } If I use a normal FOR works perfect, but have to wait for each command to finish and each query take 8 seconds, so 10 queries take 80 seconds. In the Parallel version If I only print the ranges works perfect, but if try to execute the command say is already in progress. {"An operation is already in progress."} How can I solve this? var numbers = new List<avl_range>(); using (var conn = new NpgsqlConnection(strConnection)) { conn.Open(); Action<avl_range> forEachLoop = number => /
