Can we run SQL script using code first migrations?
First you need to create a migration.
Add-Migration RunSqlScript
Then in the generated migration file you can write your SQL.
// PLAIN SQLSql("UPDATE dbo.Table SET Created = GETDATE()");// FROM FILEvar sqlFile = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Custom.sql"); Sql(File.ReadAllText(sqlFile));
Then you run
Update-Database
What I like to do is to embed the SQL script as a resource in the assembly and use the SqlResource
method. I have tested this approach with Visual Studio 2017 15.5.6.
First you need to create a migration file:
- In Visual Studio make sure to set as start up project the project where your
DbContext
is defined - In Visual Studio open the PMC: View -> Other Windows -> Package Manager Console
- In PMC Set the default project to the project that holds the DbContext
If you have both EF core and EF 6.x installed:
EntityFramework\Add-Migration RunSqlScript
If you have only EF 6.x Installed:
Add-Migration RunSqlScript
Add a Sql Script in the migration folder (I name it with the same prefix as the migration file)
In the File properties window make sure the Build Action is "Embedded Resource" Note that we don't need to copy to the output folder as the sql script will be embedded in the assembly.
Update the Up method in the RunSqlScript
migration
public override void Up(){ string sqlResName = typeof(RunSqlScript).Namespace + ".201801310940543_RunSqlScript.sql"; this.SqlResource(sqlResName );}
I hope this helps
Like SQL, we have another method SqlFile. you can directly use that.
