Changing columns datatype #1539

User avatar

I want to change column datatype. For example I don't need all the columns to be nvarchar and also I think 256 is too much for an e-mail column. What would be the best way of achieving this?

I tried to override OnModelCreating with:

base.OnModelCreating(modelBuilder); modelBuilder.ChangeAbpTablePrefix<Tenant, Role, User>(""); modelBuilder.Properties<string>().Configure(p => p.IsUnicode(false));

But I get this error when trying to update the database:

The index 'IX_Discriminator_TenantId_Name' is dependent on column 'Name'. The index 'IX_Discriminator_EditionId_Name' is dependent on column 'Name'. The index 'IX_TenantId_Name' is dependent on column 'Name'. ALTER TABLE ALTER COLUMN Name failed because one or more objects access this column.

Any ideas?

    Have you created migration (using add-migration command)? If so, can you share what it generated. Maybe it's dropping column or maybe SQL server does not allow such an operation.

    Sure:

            CreateIndex("dbo.NotificationSubscriptions", new[] { "NotificationName", "EntityTypeName", "EntityId", "UserId" });
        }

    Anyway, if we cannot change like this, is there another way? Unicode columns take twice the space if compared to non-unicode.
