Hi,

I'm trying to create a MySqlConnection with some SSL parameters, but none of this combinations: "cipher", "sslcipher", "ssl_cipher", "ssl-cipher" or "ssl cipher" are not allowed in connectionString.
Can you help me with this issue? I'm trying this:
var builder = new MySqlConnectionStringBuilder();
builder.Server = "127.0.0.1";
builder.Port = 3306;
builder.UserID = "root";
builder.Password = "password";
builder.SslCert = "C:\\file.pem";
builder.SslKey = "C:\\file.pem";
builder.SslCa = "C:\\file.pem";
builder.SslCipher = "TLS_RSA_WITH_DES_CBC_SHA"; //doesn't have this property
var conn = new MySqlConnection(builder.ToString());
conn.Open();

Regards,
Ivan!

Dear Support,



I have been having the following error message that some time appears. Most of the time it works, but it appears that some times it give me this fatal error. It appears to be random, it will work fine for some queries then that same query fails the next time it runs.
I have done some investigating and have tried to increase the connection timeouts and command timeouts, Yet on some machines this happens randomly.




Any suggestions on how to fix these errors.


The following Excpetion was caught:

Hello,

Currently receiving the following warning:

Warning NU1701 Package 'MySql.Data.EntityFramework 8.0.18' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework '.NETStandard,Version=v2.1'. This package may not be fully compatible with your project.

Though MySql.Data can target netstandard2.1, and Entity.Framework (v6.3) can target netstandard2.1.

Is this being updated in an upcoming release? 8.0.19/20

Migration from mysql-connector-net 6.6.5 to 8.0.18 (no replies)

Dear Gurus!
In previous years, a number of services have been developed that work with mysql-connector-net 6.6.5.Now I switched to VS 2019, using Blazor. To work with EF Core, I need to do scaffolding in new programs, and for this I install mysql-connector-net 8.0.18. In this regard, a few questions. Old versions of programs, if I understand correctly, must be rebuild to a new connector. Both versions of the connector will not work at the same time.
I began to do so. Install mysql-connector-net-8.0.18 and mysql-for-visualstudio-1.2.9. When accessing a specific "myobj" context table

using (gpsEntities context = new gpsEntities())
{
List<myobj> lst = context.myobjs.ToList();
}
I get error:
"System.DllNotFoundException
HResult=0x80131524
Message=MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.EntityFramework, Version=8.0.18.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d
Source=MySql.Data"
How to do it right?

Mysql .Net Connector latest version (8.0.19) does not match nuget Mysql.Data and Mysql.Data.Entity packages. On Visual Studios when Mysql database connection has selected and then clicked the next button dialogbox just close without any warning or error message. I think this because version divergent between connector (8.0.19) and the Mysql.data and entity packages .

Hi,

I want to reinstall MySQL on my laptop. To remove the existing MySQL, I uninstalled it from the Control Panel and deleted all the MySQL folders from all the locations on my laptop. Now, when I try to install it again, the MySQL Connector Net is giving issues. I am trying to remove the MySQL Connector Net but it is failing. I have removed the occurrences of the same from the Registry but still, it is failing to upgrade/remove and hence I am not able to proceed with the MySQL installation. Any help would be appreciated. Thank you in advance.

Mysql Connector LEFT JOIN Bug (no replies)

Hello,

I can't believe what I am just facing. After many hours of research I ask you guys for help:

If you left join on console, phpmyadmin, heidisql or whatever you get a different result set than with mysql connector. I checked on different windows machines with different mysql versions and different connector versions, even the latest one.

Reproduce

CREATE TABLE `test1` (
`test1_ID` INT(11) NOT NULL AUTO_INCREMENT,
PRIMARY KEY (`test1_ID`) USING BTREE
)
COLLATE='utf8mb4_general_ci'
ENGINE=MyISAM

INSERT INTO `test1` (`test1_ID`) VALUES ('1');
INSERT INTO `test1` (`test1_ID`) VALUES ('2');
INSERT INTO `test1` (`test1_ID`) VALUES ('3');

CREATE TABLE `test2` (
`test2_test1_ID` INT(11) NOT NULL,
`test2_test` VARCHAR(50) NOT NULL DEFAULT '' COLLATE 'utf8mb4_general_ci'
)
COLLATE='utf8mb4_general_ci'
ENGINE=MyISAM

INSERT INTO `test2` (`test2_test1_ID`, `test2_test`) VALUES ('1', 'a');
INSERT INTO `test2` (`test2_test1_ID`, `test2_test`) VALUES ('1', 'b');

Now run:
select test1_ID, test2_test from test1
left join test2 on test1_ID = test2_test1_ID

you will always receive 4 entries but with mysqlconnector there are only 3 rows in the resultset.

I kindly ask you for your help as I can't rely on correct results anymore.

Pull last data record into a new table (2 replies)

June 18, 2020, 2:01 pm

want to thank you all for your help right away.

2 tables, I want to pull the last record from table1 column "ProjName" and input it into table 2 column "ProjName". (I will use this field to as the relationship between the two tables).

When "add record" button on the form is pressed it writes the data to table1 no problem. So right now it is coping the entire column. I need it to just copy the last record (the newest 'Name"). ... there's also a reset button so that the record isn't saved if the user wants.

I currently have the following code to do this in the button click event:

Dim dbs As Database

Set dbs = CurrentDb
dbs.Execute "INSERT INTO tbl_ProjDetails (ProjName) SELECT (ProjName) FROM tbl_Projectsummary;"

I tried using various versions of the DLast function, needless to say it doesn't work (I don't even know if it's able to work within the INSERT INTO):

dbs.Execute "INSERT INTO tbl_ProjDetails (ProjName) SELECT DLast(ProjName) From tbl_Projectsummary);"

I have also tried just pulling from the text box directly:
dbs.Execute "INSERT INTO tbl_ProjDetails (ProjName) VALUES('" & Me.txt_projname & "')"

Any thoughts on how to do this...? I may be trying to do this scenario the wrong way, so feel free to point me in another direction.

End goal - I need to fill out 5 record sets with that name in table2, each with a different department which is another column, but right now I would just be happy getting that last record to pull - as I figure the rest will just be standard INSERT INTO
