We are migrating a database from MySQL to SQL Server. The migration is pretty straight forward and can be done quite quickly. The project using the existing MySQL database is using Hibernate within Spring MVC. If I migrated the database to SQL Server, and updated the dialect on the Spring MVC side, should the project just work without any other changes to Hibernate queries? Or do we have to make changes to every database call in the data access layer in Spring MVC? I guess I'm trying to find out where the pain points will be and if we could run into any huge issues.
It depends on dependency of your application on database features, are you using stored procedures? MySQL special functions in your HQLs? and ... If you have not used any, I believe everything will go fine

I want to establish 2 way sync between MS SQL Database with WordPress Mysql Database. I even tried to use Workbench or Microsoft SQL Server Migration Assistant for MySQL. But nothing worked. Every time i get some "Connection to MySQL Failed" Error.
I have even tried all option i have seen online but noting worked.
You have to tell us more about what you are trying to do.
As far as I can tell yo have 2 options:
Use PolyBase: Which is very impractical, close to retirement, lacking in documentation, and personally I wasn't able to install it not even once.
Use Linked Servers: As I posted in the reply you can follow the step by step guide and create a linked server to MySQL. From there you can query the linked server and eventually create a stored procedure that import/export data but forget about an on-time sync
Azure Data Factory: If you are on Azure SQL Database you can setup Azure Data Factory and create a pipeline for sync data. Or eventually use SSIS if you are on prem.
I'm attempting to migrate my rails application from postgresql to mySQL so as to view the data in one place within xampp in PHPmyadmin. The reason is the fact that I need to access the data that is located within the MySQL database from my rails app which is in postgresql.
As of now most questions I found aim to create a new application within mySQL with rails but I need to migrate all of the data my current rails application compatible and use MySQL.
Is there a proper process and simple procedure that allows for this migration from postgresql to mySQL?
Note: MySQL is within xampp
this post
got the answer to your question.
It's very easy, just paste your postgres dump in this website and you'll get the same dump converted in mysql, ready for you to be imported.
Then you will just need to properly configure your database.yml and you're set.
In an existing C# 2010 application, I want to add linq to sql tatements to connect to a sql server 2008 database. When I setup this linq to sql database, I want to be able to setup the connections to the database using the app.config file.
I have read that when you setup the database connection this way, the default database is used. Basically this is ok when you database on the same database. However, when you move from a unit testing database to a user acceptance and/or a production database there is a problem since the database connection is hard coded in the aqpplication.
Thus can you tell me and/or show me with code how to prevent this problem from occuring?
You must create partial class like This
Is there a way to use EntityFramework 4.3 beta with migrations with MySql database? Can we use migrations with MySql Database? Is it possible to use incremental database development with EF code first without me touching the database
Theoretically yes. Practically you first need to get (or create yourselves) class derived from System.Data.Entity.Migrations.Sql.MigrationSqlGenerator which will be responsible for generating SQL for MySQL. Here is more about customizing (or rewriting) SQL generation.
You can also wait until developers of EF supporting ADO.NET providers include this feature to their packages. For example Devart already started work on their migrations support for thier Oracle, MySQL, PostgreSQL and SQLite.
I've added and designed an ADO.NET Entity Data Model (.edmx) and have generated the corresponding DDL Script (.edmx.sql). When I was using SQL Server 2008, all I had to do was connect to it via the Transact-SQL Editor toolbar and execute the SQL. When I try this method, however, it doesn't let me connect to the MySQL server, as it seems to be looking only for Microsoft SQL Servers. I have the latest version of Connector/Net, and can add the MySQL database as a Data Connection, but cannot execute the script I need. What steps are needed to use an Entity Framework model with my MySQL server?
I stumbled across this little property while editing my Data Model:
(This option was installed along side Connector/Net.)
After changing to SSDLToMySQL.tt, right-click and select Generate Database from Model... as you would normally. This will generate the .edmx.sql file, and should give you several errors (as .NET uses SQL Server to parse .sql files.) After generating the DDL script, I opened up MySQL Workbench and pasted the script in. You need to make sure that an appropriately-named schema already exists on the server, then run the script, and voila.
