Hello all.
Today I dived in and tried to use DbLinq to manipulate a MySQL
database..
I ran into two problems:
1: the generated code failed to compile. The attribute "AutoGenId"
wasn't recognised. I read that this attribute was deprecated, so I
removed the corresponding code in DbMetal
2. records weren't updated when I called db.SubmitChanges()
The C# class file, generated from my database schema, didn't include
any primary key column attributes.
So, I debugged DbMetal (as I understand that VisualMetal isn't
maintained), and I patched it, so the "IsPrimaryKey" attribute is
included with every column.
If my patch is correct, can it be committed into the repository?
If it isn't correct, can anyone tell me how to get the primary key
attribute into the generated C# class properly?
Regards,
George
