I have a Mobile app, in which i want to list some data from mysql database which is already there. I am using a third party tool(DXtreme) to develop the app. When i contacted them they told me their tool will not support mysql directly. They given me some idea, but i dont get what they mean, because i am a beginner. They told "create your own data service that manipulate data using mysql. you can connect your application to your service using DataSource or oDataContenxt.Please note that ODataContent is intended only for an OData service". Please help me how can i do it ???

Could not load file or assembly MySql.Data.dll 0x80131515 (3 replies)
Hello,
I have written a PowerShell script to connect to a MySQL database to query for some information. I am using the extracted MySQL.data.dll and the script works fine, if .NET Framework 4.5 is installed. If the machine only has .NET Framework 4.0 installed, I get the below error.
add-type : Could not load file or assembly 'file:///P:\MySql.Data.dll' or
one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

The target environment is Win7 x64. I have been searching online for the last few days and found no reference that .NET Framework 4.5 was required. I am using PowerShell 3.0 but I would have thought one of the other .dlls would have worked. I have tried using the v2.0, v4.0, and v4.5 dlls to no avail. See below for the entire script.

How to do Insert in many-to-many scenario while working with entity framework for mysql? (no replies)
This should be a quite common scenario. Here're the database tables.
CREATE TABLE table1 ( ID int(11) NOT NULL AUTO_INCREMENT, Name varchar(45) DEFAULT NULL, PRIMARY KEY (ID) ) ENGINE=InnoDB DEFAULT CHARSET=utf8
CREATE TABLE table2 ( ID int(11) NOT NULL AUTO_INCREMENT, Name varchar(45) DEFAULT NULL, PRIMARY KEY (ID) ) ENGINE=InnoDB DEFAULT CHARSET=utf8
CREATE TABLE table1_table2 ( ID1 int(11) NOT NULL, ID2 int(11) NOT NULL, KEY fk1_idx (ID1), KEY fk2_idx (ID2), CONSTRAINT fk1 FOREIGN KEY (ID1) REFERENCES table1 (ID) ON DELETE NO ACTION ON UPDATE NO ACTION, CONSTRAINT fk2 FOREIGN KEY (ID2) REFERENCES table2 (ID) ON DELETE NO ACTION ON UPDATE NO ACTION ) ENGINE=InnoDB DEFAULT CHARSET=utf8
Then here's my Program.cs:
static void Main(string[] args)
{
using (testEntities ctx = new testEntities())
{
table1 t1 = new table1
{
Name = "t1",
table2 = new List<table2>()
};
table2 t2 = new table2
{
Name = "t2"
};
t1.table2.Add(t2);
ctx.table1.Add(t1);
ctx.SaveChanges();
}
}
Quite straightforward snippet. Then I got this annoying exception:
An error occurred while saving entities that do not expose foreign key properties for their relationships. The EntityEntries property will return null because a single entity cannot be identified as the source of the exception. Handling of exceptions while saving can be made easier by exposing foreign key properties in your entity types. See the InnerException for details.
A little drill-down got me to some weird sql syntax error:
{"You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(SELECT\n `table1_table2`.`ID1`, \n `table1_table2`.`ID2`\n FROM `ta' at line 1"}
Have no idea where in this auto-generated sql has syntax error.
Any clue to help me please? Thanks.

CREATE TABLE table1 ( ID int(11) NOT NULL AUTO_INCREMENT, Name varchar(45) DEFAULT NULL, PRIMARY KEY (ID) ) ENGINE=InnoDB DEFAULT CHARSET=utf8

MySql – Authentication with old password no longer supported, use 4.1 style passwords (2 replies)
I wrote a Visual Basic application to sell that uses the .NET connector 6.6.6 for MySQL.
About 50% of my customers get the message:
"MySql – Authentication with old password no longer supported, use 4.1 style passwords"
I have found that if TOAD for MySQL is used on the workstation that needs to connect and the following commands are run the problem is solved:
SET SESSION old_passwords=0;
SET PASSWORD=PASSWORD('YOURDATABASEPASSWORD');
The CPANEL/PHPmyAdmin the users have access cannot make the change to the password and I cannot run the commands remote and make it work for my users.
This means that 50% of my customers have to download TOAD, learn how to use it and run it on maybe 10 databases before they can use my application.
Is there another solution or workaround for this problem?
Can I add some code to the application to avoid the error in the first place?
Is this a bug or just a problem?

Entity Framework 6 support (1 reply)
Hi,
Hopefully we will be getting EF6 support in Connector/Net soon. Is this a goal of the Connector/Net developers?
I won't bother to ask when it will be released, but can someone please tell me the best way to get notified when Connector/Net is updated to support EF6?
Thanks

Using Cyrillic in naming database (no replies)
Good day!
It has long been using the Cyrillic alphabet when naming fields, the names of the tables and databases. It is not always immediately possible to connect to the database from Visual Studio. Now after reinstalling the OS and VS 2010 SP1 trying to restore (a new) connection to a database with the name "цукс". In the connection dialog when choosing a database from the drop down menu there is a base of the same name, among others. In additional settings specify utf8. However, I get a message "Auhtentication to localhost for user root using method" mysql native password "failed with message" unknown database '????' ". Uses a driver mysql-connector-net-6.6.5. If possible - any idea. Thanks in advance!

Cannot connect to MySql using Repository pattern (no replies)
Hi
We have got a project with multiple .Net solutions (C#) and every solution is implemented using the Repository and Unit of Work pattern. We are also using Entity Framework 5.0 as the data access technology and MS SQL as the database server. All the solutions are in visual studio 2012. Now we want migrate to MySQl server as our database server without doing much change in the design. To do this what I have done is
1. Migrated all the tables and data to MySql from Ms SQL. (We are not using any stored procedures).
2. I have installed the ADO.NET driver for MySQL which is Connector/Net 6.7.4.
3. I have added a reference to the MySql.Data.dll in the Data layer project and test project.
But every time I am trying getting the DBContext from the database I am receiving the following error:
Object reference not set to an instance of an object. at MySql.Data.MySqlClient.MySqlClientFactory.get_MySqlDbProviderServicesInstance() at MySql.Data.MySqlClient.MySqlClientFactory.System.IServiceProvider.GetService(Type serviceType) at System.Data.Common.DbProviderServices.GetProviderServices(DbProviderFactory factory) at System.Data.Entity.ModelConfiguration.Utilities.DbConnectionExtensions.GetProviderInfo(DbConnection connection, DbProviderManifest& providerManifest) at System.Data.Entity.DbModelBuilder.Build(DbConnection providerConnection) at System.Data.Entity.Internal.LazyInternalContext.CreateModel(LazyInternalContext internalContext) at System.Data.Entity.Internal.RetryLazy`2.GetValue(TInput input) at System.Data.Entity.Internal.LazyInternalContext.InitializeContext() at System.Data.Entity.Internal.InternalContext.Initialize() at System.Data.Entity.Internal.InternalContext.GetEntitySetAndBaseTypeForType(Type entityType) at System.Data.Entity.Internal.Linq.InternalSet`1.Initialize() at System.Data.Entity.Internal.Linq.InternalSet`1.get_InternalContext() at System.Data.Entity.Internal.Linq.InternalSet`1.get_Local() at System.Data.Entity.DbSet`1.get_Local()"
I have also tried to add a reference MySql.Data.Entity.dll in the Dal layer project I am receiving the following error when trying to access the DBContext
“Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.”
I have tried to add the MySql.Web.dll and same error. And then I am not using MySql.Web.dll anymore because I could not find any reason using this anyway.
For both the dls (MySql.Data.Entity.dlland MySql.Data.dll) the Copy local property was set true. And I have checked the version of the dlls. Both of them are version 6.7.4.0. The config file had the following sections added:
<system.data>
<DbProviderFactories>
<clear />
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description="Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data,Version=6.7.4.0, Culture=neutral,PublicKeyToken=c5687fc88969c44d"/>
</DbProviderFactories>
</system.data>
<connectionStrings>
<add name="MyDbContextName" connectionString="SERVER=aaa.bbb.ccc.ddd; DATABASE= MyDbContextDbName; UID=xxx; PASSWORD=xxxxx;" providerName="MySql.Data.MySqlClient"/>
</connectionStrings>
To resolve the issue I have tried the following options:
1. Removed MySql.Data.Entity.dll and MySql.Data.dll from the data layer projects, got the same dlls using the Nuget Package, and cleaned the solution but the same behaviour as above.
2. I have applied the steps mentioned in the following link http://www.jeffscorner.org/blog/category/MySQL.aspx. But the same result.
3. I have applied the steps mentioned in the following link http://stackoverflow.com/questions/14582751/mysql-connector-always-get-object-reference-not-set-to-an-instance-of-an-object. But the same result.
Our code is using the following pattern
public class MyBaseContext<T> : DbContext where T : DbContext
{
static MyBaseContext ()
{
Database.SetInitializer<T>(null);
}
protected MyBaseContext ()
: base("name=MyDbContextName")

}

{

modelBuilder.Entity<MyEntity>().ToTable("MyEntity");
}
}
[Table("MyEntity")]
public class MyEntity
{
[Key]
public string Id { get; set; }
[ConcurrencyCheck]
public int NextSeed { get; set; }
}
public class MyContext : MyBaseContext <MyContext>
{
public DbSet<MyEntity> MyEntities { get; set; }
}
public interface IMyRepository
{
MyEntity FindById(int Id);
void Commit();
}
public class MyRepository : IMyRepository

MyContext context{get;set;}
public MyRepository ()
{
context = new MyContext ();
}
#region IMyRepository Members
public MyEntity FindById (int Id)

.FirstOrDefault(x => x.Id == Id);

Going from bad to worse (1 reply)
I am trying to make MySQL work with ASP.NET (VS 2012 Web edition). I downloaded the MySql Workbench (community edition); created a table in one of the default dbs and can successfully query the table. So I know that works to some extent. Now I'm trying to create an ODBC connection. So I downloaded the 5.2 ANSI Drive (64-bit). But that didn't work. I put this into my webconfig file:
<connectionStrings>
<add name="MySQLConnStr" connectionString="{DRIVER=MySql ODBC 5.2 ANSI Driver};Database=world;Server=MySQL10;UID=XX;PWD=XXXXXX;"/>
</connectionStrings>
I get Datasource name not found; no drive specified.
I'm using the 32-bit driver.
From the Workbench, things look OK (to my untrained eye).
I've looked at ConnectionStrings.com but that doesn't seem to make a difference.
******************
NOT SURE WHAT HAPPENED: I moved the connection string data from the webconfig.xml to the app itself and, magically, it worked.

Disabling Guids from CHAR(36) columns? (no replies)
We have a SugarCRM system that we inherited. I am trying to talk to the MySQL database via a .NET MVC4 app using either Entity Framework or ADO.NET.
The problem I am running into is who ever did the initial SugarCRM install initially had it setup to use integer IDs before switching over to GUIDs.
While a majority of the keys I run across are standard GUIDs, others are "1", "2", or even "" instead of NULL.
Since SugarCRM is so large, I don't want to change a key and track down all of the places it is referenced that also have to be changed.
Is there a way to stop Connector/NET from recognizing CHAR(36) as GUID?
I've tried to override by changing the entity properties it created to string, however that just throws compile time errors stating I have a mismatch.

Cannot Install Connector Net 6.7.4 (1 reply)
Hello,
I am unable to install the Connector 6.7.4 package. The installer just exits with a generic error message.
I am running Windows 7 on a 64 bit machine.
I have the log and can supply it if required.
Any thoughts?

unable to connect to any of the specified mysql hosts (2 replies)
Hi,
I am having trouble with a process in my software application as it relates to maintaining a connection. I have a process that loops through each policy record in my database doing various data updates for each record. Randomly I will get an "unable to connect to any of the specified mysql hosts" error when doing one of those updates.
I only get this error when I run the process on my client's server. When I run the process locally on my machine within the Visual Studio IDE I do not get this error and everything is just fine.
I will point out that my client is currently running this process against another MySQL database in the same MySQL instance without any issues so I'm not sure why I'm getting this error.
I am using VB.NET and ADO.Net driver for MySQL version 6.5.4.0. My connection string is also like this "Database=xxxxx;Data Source=localhost;Port=3306;User Id=xxx;password=xxx;pooling=false;"
Thanks.

Problem of SQL parameters (2 replies)
Hello everybody,
As I needed to know my user id to insert it in another table, I inserted this code in MySqlMembershipProvider.cs
Well, I should like to know why it works only if I replace parameters explicitly by their values, while this is supposedly automatic.
Another question could concern how to call it : MySqlMembershipProvider has public values, but the user is initialised in it when signing on, and then is released. After that you have to provide connection and parameters again. Anything I did not see ?
public string GetUserKey(string Username, string ApplicationName, string connectionString)
{
string strPKID = "";
using (MySqlConnection conn = new MySqlConnection(connectionString))
{
MySqlCommand cmd = new MySqlCommand("SELECT PKID, Username, Email, PasswordQuestion," +
" Comment, IsApproved, IsLockedOut, CreationDate, LastLoginDate," +
" LastActivityDate, LastPasswordChangedDate, LastLockedOutDate" +
" FROM `" + tableName + "` WHERE Username = ?Username AND ApplicationName = ?ApplicationName", conn);
cmd.Parameters.Add("?Username", MySqlDbType.VarChar, 255).Value = Username;
cmd.Parameters.Add("?ApplicationName", MySqlDbType.VarChar, 255).Value = ApplicationName;
conn.Open();
cmd.CommandText = cmd.CommandText.Replace("?Username", "'" + cmd.Parameters["?Username"].Value.ToString() + "'").Replace("?ApplicationName", "'" + cmd.Parameters["?ApplicationName"].Value.ToString() + "'");
using (MySqlDataReader reader = cmd.ExecuteReader(CommandBehavior.SingleRow))
{
if (reader.HasRows)
{
reader.Read();
strPKID = reader.GetString(0);
reader.Close();
}
}
}
return (strPKID);
}

unable to connect to any of the specified mysql hosts (5 replies)
This is a "Public Safety" application that I am attempting to migrate to Windows 7 from Windows XP.
I am getting the message: "unable to connect to any of the specified mysql hosts" from a Visual Studio 2010 C# (GUI) application on a Windows 7 (64) computer.
The app connects to the mySQL database just fine from Windows XP 32 bit.
Things I have tried on the Win7 computer:
1) installed the MySQL Connector 6.7.4 and Visual Studio 1.0.2 using the MySQL Installer
2) created a basic GUI forms VS 2010 project to only test a mySQL connection
3) tried a reference to MySQL.Data.dll version 6.7.4 for .net 4.0
4) tried a reference to MySQL.Data.dll version 6.7.4 for .net 2.0
5) tried your nifty code here( http://dev.mysql.com/doc/refman/5.6/en/connector-net-tutorials-intro.html ) in a basic console application -- it also errors out with "Unable to connect to any of the specified MySQL hosts."
... no matter what I try I always get "Unable to connect to any of the specified MySQL hosts".
Can someone provide some assistance?

Make MySql Connector/.NET 6.7.4 use LIKE instead LOCATE with Contains? (1 reply)
I'm using the 6.7.4 .NET Connector for MySQL and i have a problem with a linq to sql query that uses the Contains .NET method.. i have to search the word 'movil' and in the DB there are words with 'móvil'.. with LIKE this returns results but because the .NET Connector uses LOCATE mysql function, then this function doesn't retrieve the same results.. how can i do to change this and use the LIKE function instead LOCATE?
If i run the result query in mysql the query doesn't retrieve any result, but if i only change the LOCATE function to the LIKE function, then this brings the correct results that i want
