Problems with Connector 6.9.7 and Find / invalid SQL (no replies)

Hi,

Pretty new to Entity Framework but not to MySQL but I'm having problems with a simple EF operation - Find - when using MySQL (connector 6.9.7), I'm using Visual Studio 2015, with an MVC application using EF6.

This Find:

News.Find(1)

produces this invalid SQL:

SELECT
`Limit1`.`C2` AS `C1`,
`Limit1`.`C1` AS `C2`,
`Limit1`.`Heading`,
`Limit1`.`MainDetail`,
`Limit1`.`Active`,
`Limit1`.`ExpiryDate`,
`Limit1`.`EmbargoDate`,
`Limit1`.`CreatedOn`,
`Limit1`.`ModifiedOn`,

`Limit1`.`C4`,
`Limit1`.`C5`,
`Limit1`.`C6`,
`Limit1`.`C7`,
`Limit1`.`C8`,
`Limit1`.`C9`,
`Limit1`.`C10`,
`Limit1`.`C11`
FROM (SELECT
`UnionAll2`.`ContentID` AS `C1`,
`Extent4`.`Heading`,
`Extent4`.`MainDetail`,
`Extent4`.`Active`,
`Extent4`.`ExpiryDate`,
`Extent4`.`EmbargoDate`,
`Extent4`.`CreatedOn`,
`Extent4`.`ModifiedOn`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (@gp1) WHEN (`UnionAll2`.`C6` = 1) THEN (@gp2) ELSE (@gp3) END AS `C2`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (`UnionAll2`.`StartDate`) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) END AS `C3`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (`UnionAll2`.`StartTime`) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) END AS `C4`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (`UnionAll2`.`EndDate`) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) END AS `C5`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (`UnionAll2`.`EndTime`) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) END AS `C6`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (`UnionAll2`.`ExernalLink`) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) END AS `C7`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (NULL) WHEN (`UnionAll2`.`C6` = 1) THEN (`UnionAll2`.`C1`) END AS `C8`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (NULL) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) ELSE (`UnionAll2`.`C2`) END AS `C9`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (NULL) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) ELSE (`UnionAll2`.`C3`) END AS `C10`,
CASE WHEN (`UnionAll2`.`C5` = 1) THEN (NULL) WHEN (`UnionAll2`.`C6` = 1) THEN (NULL) ELSE (`UnionAll2`.`C4`) END AS `C11`
FROM ((SELECT
FROM ((SELECT
`Extent1`.`ContentID`,
`Extent1`.`StartDate`,
`Extent1`.`StartTime`,
`Extent1`.`EndDate`,
`Extent1`.`EndTime`,
`Extent1`.`ExernalLink`,
NULL AS `C1`,
NULL AS `C2`,
NULL AS `C3`,
NULL AS `C4`,
1 AS `C5`,
0 AS `C6`
FROM `Activities` AS `Extent1`) UNION ALL (SELECT
`Extent2`.`ContentID`,
NULL AS `C1`,
NULL AS `C2`,
NULL AS `C3`,
NULL AS `C4`,
NULL AS `C5`,
`Extent2`.`Summary`,
NULL AS `C6`,
NULL AS `C7`,
NULL AS `C8`,
0 AS `C9`,
1 AS `C10`
FROM `News` AS `Extent2`))) UNION ALL (SELECT
`Extent3`.`ContentID`,
NULL AS `C1`,
NULL AS `C2`,
NULL AS `C3`,
NULL AS `C4`,
NULL AS `C5`,
NULL AS `C6`,
`Extent3`.`StartTime`,
`Extent3`.`EndTime`,
`Extent3`.`daysOfTheWeek`,
0 AS `C7`,
0 AS `C8`
FROM `Shows` AS `Extent3`)) AS `UnionAll2` INNER JOIN `Content` AS `Extent4` ON `UnionAll2`.`ContentID` = `Extent4`.`ContentID`
WHERE `UnionAll2`.`ContentID` = @p0 LIMIT 2) AS `Limit1`

But doing this:

News.First(x => x.ContentID == 1)

Produces valid SQL of:

SELECT
`Limit1`.`C1`,
`Limit1`.`ContentID`,
`Limit1`.`Heading`,
`Limit1`.`MainDetail`,
`Limit1`.`Active`,
`Limit1`.`ExpiryDate`,
`Limit1`.`EmbargoDate`,
`Limit1`.`CreatedOn`,
`Limit1`.`ModifiedOn`,
`Limit1`.`Summary`
FROM (SELECT
`Extent1`.`ContentID`,
`Extent1`.`Summary`,
`Extent2`.`Heading`,
`Extent2`.`MainDetail`,
`Extent2`.`Active`,
`Extent2`.`ExpiryDate`,
`Extent2`.`EmbargoDate`,
`Extent2`.`CreatedOn`,
`Extent2`.`ModifiedOn`,
@gp1 AS `C1`
FROM `News` AS `Extent1` INNER JOIN `Content` AS `Extent2` ON `Extent1`.`ContentID` = `Extent2`.`ContentID`
WHERE 1 = `Extent1`.`ContentID` LIMIT 1) AS `Limit1`

And doing this:

News.ToList().Find(x => x.ContentID == 1)

Results in even better SQL of:

SELECT
@gp1 AS `C1`,
`Extent1`.`ContentID`,
`Extent2`.`Heading`,
`Extent2`.`MainDetail`,
`Extent2`.`Active`,
`Extent2`.`ExpiryDate`,
`Extent2`.`EmbargoDate`,
`Extent2`.`CreatedOn`,
`Extent2`.`ModifiedOn`,
`Extent1`.`Summary`
FROM `News` AS `Extent1` INNER JOIN `Content` AS `Extent2` ON `Extent1`.`ContentID` = `Extent2`.`ContentID`


So I can work around the problem by using either the second or third approach instead but I'd like to know why the Find isn't working, is this a bug in the connector (I'm assuming it must be since the problem does not occur when using Sql Server) and this be fixed please?

I am writing an application using the c# and MySql database.

MySQL Command Timeout 1 second takes 6 seconds to timeout (no replies)

I previously posted the same question under "Cluster"; and I was suggested by Jonathan Stephens to post the message under Connector.
Original question: http://forums.mysql.com/read.php?25,633118

Hi,

We are working on a production environment running MySQL cluster 5.6.15-ndb-7.3.4-cluster; and the client application (VB.Net) connects to the cluster using MySQL .Net Connector 6.9.4.

The connection string to be used is:
Server=10.0.0.xxx;User ID=xxxxxxxx;Password=xxxxxxxxx;Database=xxxxx;Port=xxxx;Connection LifeTime=600;Max Pool Size=50;Min Pool Size=10;Convert Zero Datetime=True;Connection Timeout=1;

The connection timeout of 1 seconds, ensures that the connection has to succeed in 1 second, and that works correctly. Further to this we use MySQL Command to populate MySQL DataReader.

ADO Command is used:
MySQL_Command.Connection = MySQL_Connection 'This is already connected successfully
MySQL_Command.CommandTimeout = 1 '1 second (that is correct)
MySQL_Command.CommandText = SQL_String
MySQL_DataReader = MySQL_Command.ExecuteReader 'This throws exception the following exception

[5: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.]

This is correct message as the exception kicks in 1.187 seconds, and the application does take care of this, by initiating a new connection, and re-issuing the request.

But on the same code, with the same command timeout, we are also observing an exception kicking in after 6.552 seconds, this is not acceptable with our application.

Our application is a telecom application, and response time requirements are immediate, and does handle a big number of transactions without any error or timeout. As per the application, it does handle timeout exceptions (which happens rarely); and if exception kicks in, the connection are re-connected, and the commands are called again. Everything works the way it should.

But once in a while we will hit the same exception with a timeout of 6+ seconds; which should not happen as Commandtimeout is set to 1.

Would request, if someone has noticed similar behavior and have a suggestion for the same.

I am using Hostgator as my host. I'm using the .net connector 6.0.7.0 and I can't seem to get the MySqlCommand.ExecuteReader() to work. It keeps giving me the error "The given key was not present in the dictionary"

_connectionString = string.Format("server={0}; database={1}; user id={2}; password={3}; charset=utf8; pooling=false",
server,
database,
username,
password);
var conn = new MySqlConnection(_connectionString)
MySqlCommand cmd = new MySqlCommand("SELECT * FROM wp_users", conn);
MySqlDataReader reader = cmd.ExecuteReader();

Any help is greatly appreciated. I tried searching through the forums for the answer but couldn't find it.

INFORMATION_SCHEMA table gets locked (no replies)

We use stored procedures to access data from MySql server using our .NET applications. We frequently run into issue where the INFORMATION_SCHEMA table gets locked and they are in the opening state. The problem is that we are not accessing the system tables directly, so not sure if it is a limitation of MySql or there is something to do with our configuration.

Attached is a screen for the same. There are 100s of records like this.

I'm writing Windows 10 Universal App that operates on MySQL database.
But when I try to open connection with my database I get error:

An exception of type 'System.NotImplementedException' occurred in MySql.Data.RT.dll but was not handled in user code

Additional information: SSL not supported in this WinRT release.

I have disabled SSL in MySQL Workbench and also added skip-ssl command in my.ini file and I still get this error.
How can I fix this?

Unable to uninstall .NET Connector 6.4.4 (2 replies)

Hello

I'm currently trying to install .NET Connector 6.9.7 but every time I try to install it fails because of the existence on my PC of version of .NET Connector 6.4.4.

Although .NET Connector 6.4.4 is registered in the Windows Control Panel Programs and Features app and MySQL Installer 1.4.11, uninstalling, reinstallation or upgrading .NET Connector 6.4.4 fails.

There is no folder for version 6.4.4 of .NET Connector under C:\Program Files\MySQL or C:\ProgramData\MySQL but a few registry settings exist.

What follows is part of a log created by Microsoft Web Installer Platform when I tried to upgrade to .NET Connector 6.9.7.

Can you please advise?

Thanks

Martin O'Shea.

Authentication error / Reading from the stream has failed (no replies)

Using MySql 5.6.19 and .NET Connector 6.9.7.0 I get a connection/authentication error when a client application is trying to connect to MySql server running on the same machine (Windows Server 2008 x64 SP2).

Error message:

Authentication to host <ip-adres> for user <user> using method 'mysql_native_password' failed with message: Reading from the stream has failed.

Where of course <ipadres> and <user> contain the actual data used. This error does NOT occur when running the same executable and same credentials from another computer on the same LAN and connecting to this server.

The funny thing is that using the mysql command-line client the login works perfectly. So I know it's the combination of the MySql server and the .NET connector when running client + server on the same machine.

Changing ip-address to 127.0.0.1 or using a domain name does not matter; same error.

This error has already been reported as a bug for the server, but I suspect it's got something to do with the combination with the .NET connector (see also https://bugs.mysql.com/bug.php?id=76597).

So far no solution has been reported.

6.9.7.0 causes MySql syntax error in param query (no replies)

Switching from 6.9.5.0 to 6.9.7.0 has caused a parametrised update query to fail; removing then a newline character from the query suddenly makes it work again - which is clearly not how it's supposed to work.

Here's the code that used to work under older Connector .NET versions but fails with a 'You have an error in your SQL syntax; ..... at line 1' error using 6.9.7.0:

command.CommandText = @"
update
meter_stand
set
status=@status
,invoer=@invoer
where
id=@id";

pars.Clear();
pars.AddWithValue("@id", msId);
pars.AddWithValue("@status", 2);
pars.AddWithValue("@invoer", 1);
command.ExecuteNonQuery();

(where meter_stand is a table where the columns mentioned are integer, and pars is the command object's parameter collection, note that i'm using tab's instead of spaces for the query lines)

Now just changing the query (by just removing a newline) to the following makes the error disappear using 6.9.7.0; I'm quite sure that's not how it is supposed to work:

command.CommandText = @"
update
meter_stand
set
status=@status
,invoer=@invoer
where id=@id"; /* just removing the newline gets rid of the syntax error !! */

Now what to make of this behaviour? Using the latest MySql server btw.

When trying to set up an SSL secured connection using a locally stored PFX file, the follwing error is thrown when executing the Open() method of the MySqlConnection:

The PFX file has been generated from the server's SSL certificate, and is not expired. My connection string reads "server=123.45.67.89; database=name-of-db; username=name-of-user; password=secret; SSL Mode=Required; CertificateFile=C:\client.pfx; CertificatePassword=secret; use compression=true"

DataSet null exception (no replies)

Hi there,

Can anyone give me a "hand" with this problem? I am making a C# app with mysql database server. The aplication has to process 12000 records by day (more or less). My real problem is not the amount of data to process but a strange problem with the adapter of the datatable on the main dataset.


here is the command collection used by the below method:
this._commandCollection[2] = new global::MySql.Data.MySqlClient.MySqlCommand();
this._commandCollection[2].Connection = this.Connection;
this._commandCollection[2].CommandText = @"SELECT `id` FROM `process_roll_parts` WHERE roll_id =@roll_id AND part_id =@part_id";
this._commandCollection[2].CommandType = global::System.Data.CommandType.Text;
param = new global::MySql.Data.MySqlClient.MySqlParameter();
param.ParameterName = "@roll_id";
param.DbType = global::System.Data.DbType.Int64;
param.MySqlDbType = global::MySql.Data.MySqlClient.MySqlDbType.Int64;
param.IsNullable = true;
param.SourceColumn = "roll_id";
this._commandCollection[2].Parameters.Add(param);
param = new global::MySql.Data.MySqlClient.MySqlParameter();
param.ParameterName = "@part_id";
param.DbType = global::System.Data.DbType.Int32;
param.MySqlDbType = global::MySql.Data.MySqlClient.MySqlDbType.Int32;
param.IsNullable = true;
param.SourceColumn = "part_id";
this._commandCollection[2].Parameters.Add(param);

this is the method that I invoque to access the data and get it back:

[global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
[global::System.CodeDom.Compiler.GeneratedCodeAttribute("System.Data.Design.TypedDataSetGenerator", "4.0.0.0")]
[global::System.ComponentModel.Design.HelpKeywordAttribute("vs.data.TableAdapter")]
[global::System.ComponentModel.DataObjectMethodAttribute(global::System.ComponentModel.DataObjectMethodType.Select, false)]
public virtual long GetProcessRollPartsDataByID2(long roll_id, int part_id)
{
this.Adapter.SelectCommand = this.CommandCollection[2];
this.Adapter.SelectCommand.Parameters[0].Value = ((long)(roll_id));
this.Adapter.SelectCommand.Parameters[1].Value = ((int)(part_id));
global::System.Data.ConnectionState previousConnectionState = this.Adapter.SelectCommand.Connection.State;
if (((this.Adapter.SelectCommand.Connection.State & global::System.Data.ConnectionState.Open)
!= global::System.Data.ConnectionState.Open))
{
this.Adapter.SelectCommand.Connection.Open();
}
try
{
int returnValue = int.Parse(this.Adapter.SelectCommand.ExecuteScalar().ToString());
return returnValue;
}
finally
{
if ((previousConnectionState == global::System.Data.ConnectionState.Closed))
{
this.Adapter.SelectCommand.Connection.Close();
}
}
}


The is that in run time the line "this.Adapter.SelectCommand = this.CommandCollection[2];" returns SystemNullNxception, so used the debug and what I find out is that just after the debugger enter this method the "this.CommandCollection[2]" is NULL but if I wait for 2 second it will be not NULL. Anyone has came accross this problem? .Net 4, MySql Connector 6.9.7.0, VS 2013 Community.

Any idear how to repair this issue?

Best regards,
Pedro Dias

Entity framework returns entity which doesn't exist in database (no replies)

I got a very strange behavior with EF6. I have an entity which insertion failed, but when i enumerate the entities, the first time after that, I retrieve the entity, even if i create a new context
Here a sample code in C#


MyDbContext ctx = new MyDbContext();
Category category = new Category()
{
Name = "TEST INSERTION FAILED",
TranslationCategories = new List<TranslationCategory>()
{
new TranslationCategory()
{
LangId = "FR",
Name= "FR translation"
}
}
};
try
{
ctx.Categories.Add(category);
await ctx.SaveChangesAsync();
}
catch(Exception ex)
{
Console.WriteLine(ex.Message);
// throw exception because "TranslationCategory" table doesn't exist in DB
}
MyDbContext ctx2 = new MyDbContext();
foreach(var o in ctx2.Categories.ToList())
{
Console.WriteLine(o.Name);
//output : "TEST INSERTION FAILED" + categories stored in DB
// Why category "TEST INSERTION FAILED" in ctx2.Categories ?
}
Console.WriteLine("****************");
foreach (var o in ctx2.Categories.ToList())
{
Console.WriteLine(o.Name);
// ouput : only categories stored in DB
}


The same code, with same schema in sql server, doesn't reproduce this bug.

Workbench Connects/Auths to Database but Application Fails (no replies)

A puzzling problem to me.

I can connect to my database using mySQL Workbench and manipulate the data however my .NET app using the same credentials is denied.

---Authentication to host '(server FQDN)' for user 's_user' using method 'mysql_native_password' failed with message: Access denied for user 's_user'@'us00020324.company.se' (using password: YES)---

The DBA's explanation was not clear to me, the mySQL log shows:

--- log: 2015-10-08 13:47:24 12996 [Warning] IP address 'x.x.x.x' could not be resolved: Name or service not known ->> where x.x.x.x is a real IP. ---

Then she said something about no PTR but did not say if that mattered.

So my app only has 'username' specified for the DB connection NOT user@domain.

The SQL server error appears to append the domain, which is my PC name and company domain.

I dont know what the problem is.. the username should be different or the SQL server is doing a reverse lookup??? But why does it work with Workbench.

Nothing is ever easy. Thoughts.. Thanks!
