firebirdsql | Firebird RDBMS sql driver for Go | SQL Database library

I want to develop a demo project in ASP.NET Core MVC with embedded Firebird v2.5. I read Firebird connection string information from a text file. Because I will change database in project presentation thus I must read from a text file. Or what is the your idea?

In this project I create a DbContext file and I fill in the database information using this class:

I'm developing a RESTful application and whenever I make a request, it works fine, but also outputs these warnings:

I am attempting to run a working jmeter script in blazemeter, but getting the following error where it tries to run my groovy scripts. I am writing trying to access jmeter properties that were set in a previou groovy script.

I had to switch my code from being in .NET Core to .NET Framework and now I get an error. the error says that local variable named 'listadb' cannot be declared in this scope. This function worked before and I don't know how to get around it now. Here is the code:

I have this program, that I have to handle the exceptions for, but I never done it so I'm kind of confused. I'm guessing I'd have to handle exceptions like the value in the textfile is empty, there is no index, there is no "=" or the file is empty, but I don't really know how to define them or where to put them. Here is my code: (the lines in the text file should look like this: EMPIS_MAG_BUDOW=12

EMPIS_DESKA_FASOLKA=2

SM_PORTAL_POL1=-4 )

I have to make a select statement on a database and than compare the results with a text file using only C# in Visual Studio. If the text file has a bigger value than the record in the database, the program returns the value from the text file, and if the database record has a bigger value, the program returns the value from the database. The results are added to a list being a class WynikPorownania{}. The user types in the file an index of a product and the value(in this case the value is it's availability condition).

For example:

The textfile says this:

WYR_WR_CZ1=12

VIDIS_JIMU_BOX=3

REREK_KOTEK_T=5

In the database, theses indexes are connected to an availability condition like this

WYR_WR_CZ1=-1.0000

VIDIS_JIMU_BOX=-13.0000

REREK_KOTEK_T=0.0000

Now the program should return the bigger value in a list being the WynikPorownania{} class.

For now, I managed to do this much: I took every record from the select query and put it in to a list as a class. I have a function that checks the "standysp"(availability condition) for a specified index, and I asigned the text file value to a string. I think that it could be done maybe with this "zwr" function and maybe a loop but I don't really know where to go from now on. This is my code for now:

I have transactional service that I use to create a Person and persist it in db. The problem is that entity is not saved into db after transaction is commited.

At first I thought it was the fault of the JpaRepository, which opens a new transaction every time a method is called, but from what I've learned, these are just logical transactions inside a single physical one that gets opened in my service.

I use Spring Boot and Hibernate to connect with my firebird databases. For this purpose i configured two separate datasources and transaction managers. In each @Transactional annotation, I specify the transaction manager to be used. Fetching data works perfect. The problem concerns only saving.

I'm actually performing more operations here, but for the sake of the example I'll limit myself to just saving the entities. Simple example below.

I'm trying to read fdb files in Ubuntu using firebirdsql:

I recently downloaded the new Firebird 4 server and installed it. It's running as a service on my Windows 10 box. I'm able to connect to it just fine with the FB Maestro IDE, but when I try to connect to it from some ADO.NET code, I get an error. Upon calling await connection.OpenAsync (where connection is a FirebirdSql.Data.FirebirdClient.FbConnection instance):

FirebirdSql.Data.Common.IscException: 'Error occurred during login, please check server firebird.log for details'

Looking at the server log, I see the following two errors, repeated various times:

DESKTOP-NAME Thu Jun 24 15:14:32 2021 Authentication error No matching plugins on server

DESKTOP-NAME Thu Jun 24 15:14:35 2021 INET/inet_error: read errno = 10054, client host = DESKTOP-NAME, address = 127.0.0.1/54653, user = Mason

I have no idea what this means, and some basic searching fails to turn up anything useful. Anyone know what I need to do to resolve this?

In case it's relevant, my connection string looks like this:

User=SYSDBA;Password=[my password];Database=[db name];DataSource=localhost;Port=3050;Dialect=3;Charset=UTF8;

Once again, I know the server is working correctly because I can connect to it with FB Maestro. The problem is clearly in my .NET code somewhere. I just have no idea where!
