database-migration

For an project, I need to migrate an Access database to SQL server 2012 express, I found some ways to do this, like using Microsoft up-sizing, but this question is not very technical but just to find out alternative ways, the database in access contains confidential data, so im not allowed to see data and I want to find out is there is any procedure that can be useful for me to achieve migration with out seeing the database itself and how to verify the data is exact in both. I don't have database background so specific directions and resources is useful. I don't know how to search for specific

I have created an website using ASP.Net, a table using SQL Server, and I have published it to a provider. What I want is to convert the MSSQL.sql file to Mysql.sql file. Is there any free software, or some code to convert it to SQL Server to MySQL ? It would be much appreciated if someone could help me. If you use phpMyAdmin to manage your MySQL (which almost all web hosts use) you can simply import the file in compatibility mode for MSSQL. To do this, go to Import -> Choose your file -> Then select "MSSQL" from SQL compatibility mode: under Format specific options. If you don't have

Is it possible to do any type of programmatic data transformation in Entity Framework 5 Code First migrations? There is an Sql () method to execute queries, but it has return type void and I don't see any way to get the results of the queries I perform. Example I have table Recipe with one-to-many relationship to Ingredient . For various reasons I want to convert this to a Ingredients JSON string property instead. The only approach I can think of is something like this: Create new column IngredientsJson For each recipe, query its ingredients, construct a JSON string programmatically and insert

Does alembic upgrade head run inside a transaction so that all database alterations succeed, or fail? If not, why was it designed this way? My understanding is alembic runs inside a transaction for databases that support it, like Postgres. If you're on a database that does not support this ( cough MySQL cough ), you can't use this functionality. Alessandro Cosentino That's something you can decide within the env.py , which is where you customize the behaviour of the migrations to suit your setup. You can see how to make sure your upgrades happen in a transaction from the template provided as

In many flavors of SQL, there are three ways you can implicitly set a column to NULL on every row insertion. These are: columnname type NULL columnname type DEFAULT NULL columnname type NULL DEFAULT NULL I.e. the first one sets the NULL flag (as opposed to NOT NULL), second one leaves the NULL flag to the default value, and the third one sets the NULL flag and sets the implicit value as NULL. I've heard about how in Microsoft SQL, the second variation is not exactly the same since you can also customize the default value of the NULL flag for tables or schemas. But for MySQL, I don't believe

We're using Database first approach with EntityFramework. We've several customers, and when we deploy new product version, we're now applying DB schema changes "manually" with tools like SQL Compare . Is there a way how EF Migrations could help to apply changes to customers DB automatically? Paul As far as I know, EF Migrations is a product targeted at CodeFirst and doesn't support Database First operations. CodeFirst assumes that you will never make any changes manually to the database. All the changes to the database will go through the code first migrations. I think there is! You need to

I have django app named "app1" with models and migrations files. I renamed this app to "app2" and I fixed all imports, urls ... But I have a problem with migrations files and data in tables. How can I write migrations with the correct way to ensure: - New installation => create the new tables - Update old versions => create new tables, move data, remove old tables PS: there is several tables with many FK.
