Hi there,

Is there any guidance with how we should deal with a loss of database connection from the server side when using the new IBEvents?

At first we tried using IBConnection's StateChange event but this only fires when the client is initiating the change (ie: on calling Open() or Close()). It does not fire if the InterBase service were to stop (whether gracefully or not).

Thanks,

Nick

Hello,

Hopefully I can get some help with this when I do a basic connection to my database when I get to the connection open I get this error in my output in Visual Studio 2022 tried in .net6 and .net7 (IOS and ANDROID) but works fine no error on (Windows)

When I run this for windows no error everything connects fine but when I run it for either mobile on physical device or simulator no luck.

This is the basic code I am using to connect (I replaced user and password with holders)

string connectionstring = @"data source=tamrds01/interbase09;initial catalog=C:\Sales\Tamco_SC\TAMCO_SC.ib;user id=sample;password=sample";
var conn = new IBConnection(connectionstring);
conn.Open();
IBCommand command = new IBCommand("select * from sxpwd", conn);
IBDataAdapter dt = new IBDataAdapter(command);
dt.Fill(Test);

Any help would be great thanks!

Hello,

first up, thank you for providing an Entity Framework Core provider for Interbase.

Due to the fact that there have only been some commits in April and May and only EF Core 3.1 is mentioned in the docs:
Was this a one time effort or will this project be actively maintained?

Thinking ahead, EF Core 3.1 LTS will only be supported until 2022-12-03 and there is already a stable version of EF Core 6.0 with LTS support.
Are there any plans to support Entity Framework Core 6.0 (and/or 5.0 as and intermediate step) within the next n quarter(s) / the next year?

Hi,

We could not connect the interbase DB using this driver. The following errors comes

1. Error : An invalid connection string argument has been supplied or a required connection string argument has not been supplied.

Used the below connection string format
<add name="Conn" connectionString="server=localhost/3050:<DB PATH>;user=TEXDBA;password=texdba;port=3050;charset=None;" />

Please suggest how to solve this issue or do we need to install any dependencies.

Thank You

Embarcadero.Data.InterBaseClient.csproj has a dependency on NUnit3TestAdapter. Is this required? It seems a bit odd for a database driver to link to any unit test library.

Hi, Jeff, this is more of a request than an issue, I am used to being able to trim/truncate the char fields so that all strings are presented as if they were varchar. actually with other .Net Providers there are options in the connection string for this. for example IBProvider has "truncate_char = true" as default. This is convenient because I never want strings to have spaces. Is this something IB.NETDataProvider supports? I looked through the connection string documentation and did not see the feature. Unfortunately my existing DB has many char fields as well as varchar, but I would like to treat them all as varchar and not have to worry about trimming every field up on reading. Thanks,

There is a whitespace difference between what is documented in the wiki and what is in code. Wiki says SEPPassword however in code it is SEP password (ConnectionString.cs). Attempting to use the documented SEPPassword does not work. SEP password (with the extra whitespace) is working though.

See: http://docwiki.embarcadero.com/InterBase/2020/en/Setting_the_System_Encryption_Password_(SEP)

If I setup Entity Framework to log the SQL being executed, this is the result

      SELECT "k"."ADD1_KANJI", "k"."ADD2_KANJI", "k"."ADD_KANA", "k"."KANK_CD", "k"."KANK_SYUBETSU", "k"."HOUJIN_NO", "k"."KORYOKU_ED", "k"."KORYOKU_SD", "k"."JIGYOSYO_NO", "k"."K_H_KBN", "k"."KANK_NAME1_KANJI", "k"."KANK_NAME2_KANJI", "k"."KANK_NAME_KANA", "k"."TEL", "k"."ADD_NO", "k"."TOROKU_YMD", "k"."TARGET_FLG"
      FROM "KANK" AS "k"

I attempted to connect to the database using isql and tried a query using a similar syntax, and it threw the same error.

SQL> SELECT "k"."KANK_CD" FROM "KANK" AS "k";
Statement failed, SQLCODE = -104

Dynamic SQL Error
-SQL error code = -104
-Token unknown - line 1, char 11
-.
SQL>

If I remove the quotation marks and run SELECT k.KANK_CD FROM KANK AS k; it works as expected.

I'm not very experienced with Interbase, but it seems as though perhaps using quotations like that isn't supported? I think it is getting parsed as being a string, as if I do SELECT "FOOBAR" FROM KANK it outputs a bunch of "FOOBAR" for each row.

Is there some configuration step for Entity Framework that is necessary in order to make it work correctly?

I have Interbase 2022 installed on my local machine including the ODBC driver.

My Windows machine's encoding is set to ShiftJIS (as it is the default Japanese encoding).

The remote Interbase instance does not have an encoding set, which to my understanding means that it should default to the host machine's encoding. The host machine of that remote instance is also set to ShiftJIS.

If I connect to the instance using isql, I can properly retrieve Japanese encoded text.

Since I am having trouble using Entity Framework's ORM functions as described here, I've set up a different endpoint to execute SQL directly which looks like this,

[HttpGet("test")]
        public async Task<string> Test()
        {
            var result = "";
            using (var command = db.Database.GetDbConnection().CreateCommand())
            {
                command.CommandText = "SELECT KANK_NAME1_KANJI FROM KANK";

                db.Database.OpenConnection();

                using (var reader = await command.ExecuteReaderAsync())
                {
                    if (reader.Read())
                    {
                        result = "";
                        result += reader.GetString(0);
                    }
                }
            }
            return result;
        }

If I set the connection string to @"User=USERNAME;Password=password;Database=c:\DATABASE.GDB;DataSource=999.999.999.999 and execute it, I get this result,

�q�j�a���������������                  

It seems like I'm having some kind of problem with the encoding. I thought that I should perhaps try to specify the encoding inside the connection string, however if I set the connection string to @"User=USERNAME;Password=password;Database=c:\DATABASE.GDB;DataSource=999.999.999.999;Charset=SJIS_0208 and execute it, I get this result

I tried setting breakpoints and debugging this, and it seems like this is coming from the reader.Read() call. It seems like perhaps the reader is unable to handle ShiftJIS?

We would really like the ability to listen for events being posted in our database.

We got quite excited when we saw the example code in events.md. Less excited when we realised the remote events methods in IBDatabase throw NotSupportedExceptions 😬😅

Is this feature on the horizon at all?

Hi there,

Thanks again for the great work on #11. It has been working realy well for us so far.

So well infact that we are currently at 14 registered events. It's not going to be long before we're going to hit the 15 registered events limit.

Is there any progress on removing this limitation?

Alternatively, are there any recomended workarounds for now?

Thanks again.

Hi there I have been pained by these drivers lack of proper support for booleans. Whether it is querying the db or inserting an entry with a boolean.
For example
BoolHolder foo = new BoolHolder {test = true, id = 1};

`

        var context = GetContext(session);
        using (IDbContextTransaction transaction = context.Database.BeginTransaction())
        {
            try
            {
                context.Entry(foo).State = EntityState.Added;
                await context.SaveChangesAsync();
                await transaction.CommitAsync();
            }
            catch (Exception ex)
            {
                transaction.Rollback();
                Console.WriteLine("Error occurred.");
            }
        }`

This will be added to my database with the boolean being randomly assigned a false or true value.
A simple workaround is doing something like
(EDIT: THIS ACTUALLY DOESNT FIX IT SAME ISSUE OCCURS WHEN USING PARAMETERIZED UPDATEDS W/ RAWSQL)

`

        var context = GetContext(session);
        using (IDbContextTransaction transaction = context.Database.BeginTransaction())
        {
            try
            {
                context.Entry(foo).State = EntityState.Added;
                await context.SaveChangesAsync();
                await transaction.CommitAsync();
                await context.Database.ExecuteSqlRawAsync("UPDATE Boolholder SET test = @p0 WHERE id = @p1", foo.test, foo.id);
            }
            catch (Exception ex)
            {
                transaction.Rollback();
                Console.WriteLine("Error occurred.");
            }
        }`

And that seems to work fine however this problem is even more of a headache when trying to retrieve data. Trying to query something based on a boolean just straight up does not work. You'd have to workaround it by switching flags to another datatype

EDIT: SEE PHOTO BELOW NOT EVEN RAWSQL WORKS WITH PARAMETERISED VALUES ONLY HARD TYPING BOOL VALUES WORK ?????????

Console.WriteLine($"Pickup : {order.Pickup}");
Console.WriteLine($"Pickup : {order.MultiPay}");
await context.Database.ExecuteSqlRawAsync("UPDATE OrderHdr SET Pickup = @p0, Multi_Pay = @p1 WHERE Order_Id = @p2", order.Pickup, order.MultiPay, order.OrderId);

After installing the github package, I was able to successfully access the db. However the I was not able to create a data connection as the ADO support was not installed in the DDEX for VS 2019

Problem

Getting a NullReferenceException when attempting to alter a procedure containing the DATE keyword. This could be expected for clients or servers using Dialect 3, however I am setting the Dialect to 1 via IBConnectionStringBuilder.Dialect and can confirm that the server is also set to Dialect 1 (the same statement executes properly with IBConsole and IBExpert)

Investigation

After debugging the InterBaseSql.Data.InterbaseClient package myself, I was able to determine that the underlying error is actually:
"DATE data type is now called TIMESTAMP", which tells me the issue likely has something to do with the Dialect.

SQL Dialect Documentation

The DATE data type contains both time and date information and is interpreted as TIMESTAMP; the name has changed but the meaning has not. Dialect 1 clients expect the entire timestamp to be returned. In dialect 1, DATE and TIMESTAMP are identical.
