In Entity Framework 6, I need to get the SQL script for specific migration file and I already updated the database. I found that in
update-database command I can add script parameter to export the migration to SQL, but I already updated the database. I found in Entity Framework Core, a command called
Script-Migration with script name as an argument. Is there any similar command in Entity framework?
I also tried the suggestion "Update database command", but I got an empty SQL file.
Yes, you could generate the migration-SQL as follows:
Update-Database -Script -SourceMigration: <pointFromWichYouWantToStartWithGeneration> -TargetMigration: <pointWhereToEndWithGeneration>
To create a script for all migrations execute the following:
Update-Database -Script -SourceMigration: $InitialDatabase
Instead of applying the changes to database it will generate a SQL script file. Therefore you could generate a SQL Script even if the migration was already applied to the database.
Here you could find some more information about it - Entity Framework Code First Migrations - Getting a SQL Script.
Update-Databasecommand but this time specify the
â€“Scriptflag so that changes are written to a script rather than applied. Weâ€™ll also specify a source and target migration to generate the script for.
If you're now in .net core use
Script-Migration -From <PreviousMigration> -To <LastMigration>
