मैं mysql कनेक्टर के साथ इकाई फ्रेमवर्क 6 में एक तालिका को बदलने की कोशिश कर रहा हूं।AlterProcedureException जब मैं अद्यतन-डेटाबेस कमांड का प्रयास करता हूं EF6 MYSQL
त्रुटि है:

मेरे संदर्भ है:
[DbConfigurationType(typeof(MySqlEFConfiguration))]
public class GiveAndGetContext : DbContext
{
public GiveAndGetContext()
: base("GiveAndGetContext")
{
//Database.SetInitializer(
// new MigrateDatabaseToLatestVersion<GiveAndGetContext, DAL.Migrations.Configuration>("GiveAndGetContext"));
}
//Para crear des de presentation
// // Constructor to use on a DbConnection that is already opened
// public GiveAndGetContext(DbConnection existingConnection, bool contextOwnsConnection)
//: base(existingConnection, contextOwnsConnection)
// {
// }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);
modelBuilder.Entity<Category>().MapToStoredProcedures();
modelBuilder.Entity<City>().MapToStoredProcedures();
modelBuilder.Entity<Controller>().MapToStoredProcedures();
modelBuilder.Entity<Country>().MapToStoredProcedures();
modelBuilder.Entity<Interest>().MapToStoredProcedures();
modelBuilder.Entity<Item>().MapToStoredProcedures();
modelBuilder.Entity<Language>().MapToStoredProcedures();
modelBuilder.Entity<Literal>().MapToStoredProcedures();
modelBuilder.Entity<Province>().MapToStoredProcedures();
modelBuilder.Entity<Region>().MapToStoredProcedures();
modelBuilder.Entity<User>().MapToStoredProcedures();
modelBuilder.Entity<View>().MapToStoredProcedures();
modelBuilder.Entity<prueba>().MapToStoredProcedures();
}
}
}
Configuration file of migrations is:
internal sealed class Configuration : DbMigrationsConfiguration<DAL.Context.GiveAndGetContext>
{
public Configuration()
{
AutomaticMigrationsEnabled = false;
SetSqlGenerator("MySql.Data.MySqlClient", new MySql.Data.Entity.MySqlMigrationSqlGenerator());
}
मेरे package.config फ़ाइल है:
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="EntityFramework" version="6.1.3" targetFramework="net46" />
<package id="MySql.Data" version="6.9.8" targetFramework="net46" />
<package id="MySql.Data.Entity" version="6.9.8" targetFramework="net46" />
</packages>
और उदाहरण ऐड-प्रवास के फ़ाइल है:
using System;
using System.Data.Entity.Migrations;
public partial class _2 : DbMigration
{
public override void Up()
{
AlterColumn("dbo.pruebas", "Name", c => c.Short(nullable: false));
AlterStoredProcedure(
"dbo.prueba_Insert",
p => new
{
IdController = p.Short(),
Name = p.Short(),
},
body:
@"SET SESSION sql_mode='ANSI';INSERT INTO `pruebas`(
`IdController`,
`Name`) VALUES (
@IdController,
@Name);
SELECT
`Id`
FROM `pruebas`
WHERE row_count() > 0 AND `Id`=last_insert_id();"
);
AlterStoredProcedure(
"dbo.prueba_Update",
p => new
{
Id = p.Short(),
IdController = p.Short(),
Name = p.Short(),
},
body:
@"UPDATE `pruebas` SET `IdController`[email protected], `Name`[email protected] WHERE `Id` = @Id;"
);
}
public override void Down()
{
AlterColumn("dbo.pruebas", "Name", c => c.String(unicode: false));
throw new NotSupportedException("Scaffolding create or alter procedure operations is not supported in down methods.");
}
}
मैं कमांड के साथ डेटाबेस बना सकता हूं, और एक नई तालिका जोड़ सकता हूं, लेकिन मैं किसी तालिका के कॉलम को संशोधित नहीं कर सकता (ड्रॉप कॉलम या कॉलम जोड़ें)। समस्या ड्रॉप नहीं है, यह AlterStoredProcedure विधि है।
