unhandled error from mysql_next_result() when calling stored procedure from ODBC (1 reply)

Hello everyone, I am developing a .NET website using Framework 4.0 and the ODBC connector to MySQL. (For some reason I couldn't find how to use the Connector\net with datasource objects, but that is for another post).

I am calling a stored procedure with one input parameter and two output parameters. When calling it from MySQL workbench it works as expected, but when calling it from my .net project it gives the error below.

So here is the .net code:
OdbcConnection o = new OdbcConnection(ConfigurationManager.ConnectionStrings["CervezaPro"].ToString());
o.Open(); //Se abre la conexión a base de datos
OdbcCommand oc = o.CreateCommand();
oc.CommandType = CommandType.StoredProcedure;
oc.CommandText = "{ CALL CongelarProceso(?,?,?) }";
oc.Parameters.AddWithValue("p_idRecetas", DDLReceta.SelectedValue);
OdbcParameter mensaje = new OdbcParameter("p_mensaje", OdbcType.VarChar,2000);
mensaje.Direction = ParameterDirection.Output;
OdbcParameter resultado = new OdbcParameter("p_resultado", OdbcType.Int);
resultado.Direction = ParameterDirection.Output;
oc.Parameters.Add(mensaje);
oc.Parameters.Add(resultado);
oc.ExecuteNonQuery();

And this is the stored procedure:
CREATE DEFINER=`root`@`localhost` PROCEDURE `CongelarProceso`(in p_idRecetas int, out p_Mensaje varchar(2000), out p_resultado int)
BEGIN
DECLARE done INT DEFAULT FALSE;
dECLARE vStatus int;

end loop;
end;
if p_resultado = 0 then
UPDATE procesoelaboracion
SET
congelarproceso = 1
WHERE
recetas_encabezado_idrecetas = p_idRecetas;
end if;
END

And finally, this is the error that appears when executing from .NET:

Access 2002 Forgetting mySQL login info (no replies)

Connector: ODBC5.1

I am running Access 2002 on Server 2003 and for the better part of a year my ODBC connection to a remote mySQL database worked perfectly.

One day it started making me re-enter the User: and Password: once after each time my database application was restarted.

More recently, it started randomly forgetting this info without the application even being restarted. In this case, inputting just the User: field seems to make it resume the connection.

I have uninstalled and re-installed the 5.1 connector but the problem persists. I tried installing the latest ODBC connector but for some reason it will not install on my server.

Has anyone experienced this problem and if so were you able to solve the issue?

Win7 32bit programmatic DSN creation causing Exception (1 reply)

I am trying to add a DSN from a C#.Net application.

I am using the following,
SQLConfigDataSource from ODBCCP32.dll

When calling, I receive a System.AccessViolationException

I don't receive this exception when using a different driver (such as "Sql Server")

Also worth noting, is that if I remove myodbc5S.* from the mysql connector directory this exception no longer happens and the call executes and returns an odbc error:
ODBC Error <ODBC_ERROR_LOAD_LIB_FAILED>: The setup routines for the MySQL ODBC 5.3 ANSI Driver ODBC driver could not be loaded due to system error code 126: The specified module could not be found. (C:\VPD3\VPD3 Database\5.3.6-win32\myodbc5S.dll).

From what I can tell the myodbc5s.* files support the GUI part of making a DSN connection.

Is there a way to turn this feature off? Has anyone else had a problem with this?

Hi All,

Connecting Alteryx software to our database using an ODBC connector (64bit). Using a pre-written SQL statement I am attempting to query customer feedback. I've noticed that when reporting straight from MySql (connecting straight to our database) the verbatim is full and complete.

However, when reporting the same query through the ODBC connector, the verbatim is truncated.

Is there a way I can specify my ODBC connector to not truncate? Or is there perhaps something I'm doing wrong?

Appreciate the help.

Hello!

My customer use the Connector/ODBC 5.3.6 for Windows x84.
https://dev.mysql.com/downloads/connector/odbc/
The ODBC is used to connect to a MySQL running on another machine.

The customer have configured an MySQL ODBC 5.3 Unicode Driver in Window's ODBC configuration tool at C:\Windows\SysWOW64\odbcad32.exe.
This window is displayed to configure the ODCB-connection: https://dev.mysql.com/doc/connector-odbc/en/images/myodbc-win-odbcadmin-adddsn-5-1.png

When the customer press the "Test" button the connection fails. But when pressed again the connection is successful and the possible databases/schemas can be shown in the configuration tool.


In my application where the ODBC-connection is used, the application crashes when trying to open the connection the first time. When trying to open again, the connection is established.

The exception which was thrown has this error message:
"ERROR [HY000] [MySQL][ODBC 5.3(w) Driver]Can't connect to MySQL server on '10.205.210.65' (10060)"


In sequence this happens:

Open() // Fails with the above exception.
Open() // Works

My customer have verified the connection to the MySQL-server on the remote machine with the MySQL Workbench. There is no problems with any permissions or network. Everything works except for first time when the connection should be established.

What could be the problem?

Optional Featrue Not Implemented (1 reply)

Windows 10
MySQL 5.7.9
MySQL ODBC Driver 3.51 32-bit
OpenOffoce 4.1.3
JRE 1.8.0_73 Installed

I have a good ODBC connection to a MySQL database on a remote server at Lunar Pages.
The connection works perfectly using MS Access 2K.

Opening up Base, I can "see" the database with all the tables listed.

Attempts to retrieve data by Linking to a list box or simply clicking on any of the tables gets this error message:

The Data Content Could Not Be Loaded
[MySQL][ODBC Driver][mysqld-5.6.27-75.0]Optional feature not implemented.

But if I create a SQL query to retrieve only one column, it works.

So I presume that an ODBC connection through OpenOffice needs "something else" that is either unnecessary or native in MS Access.

If you click "More" to learn about the error, you see:
SQL Status: HYC00
Error Code: 537

So the questions are: What optional feature? And how do I implement it?

Could this be related to Windows 10?

I've put these same questions to the OpenOffice forum, so far without success.

Any suggestions appreciated.

primary key detection w/odbc 5.3 ansi (no replies)

Hello friends -

Working with a data modification tool that uses odbc connections. Trying to talk to a 5.6 database using odbc 5.3 ansi. Reading and first time inserts work great. If I ask the tool to 'update, insert if new', I get primary key violations thrown back up; i.e., it's seems unable to tell that row identifier x exists, and tries a duplicate insert.

Vendor is blaming the ODBC driver implementation, which is consistent with the fact that if I change my target database to sql server, I see acceptable results. That being said, I'm curious if others have seen problems with primary key identification using odbc 5.3. I did see a SO thread regarding the sun jdbc:odbc bridge indicating DatabaseMetada.getPrimaryKeys() was not implemented, but I could not find anything else in Google land to validate that if this was a failing of the standard odbc driver.

Any insight is appreciated.

We have an MYSQL database which we have linked the Tables in an Access Database using the ODBC. I have installed and configured the ODBC in several computers and they all work fine. I have this one computer which I have configured the same way. I created the same ODBC connection in the Control Panel and test connection is successful. However when I open the access and try to read from the linked table I get an error "Run-time error 3151 ODBC-- connection to ... failed. I tried logging in with the Admin user but same thing. I can't figure out what could be different on this computer. I don't know where to look. Is there any logging that might help find the issue.

Thanks,
