-----------------------------------------------------------
Key: DNET-718
URL: http://tracker.firebirdsql.org/browse/DNET-718
Project: .NET Data provider
Issue Type: Bug
Components: Entity Framework support
Affects Versions: 5.6.0.0
Environment: ,Net 4.5.2 EF6.1.3 Firebird 2.5.2 .NetProvider 5.6.0.0
Reporter: Leonard Wennekers
Assignee: Jiri Cincura
The migration below will generate an exception on the trigger because of the
identify: true inside SequenceId = c.Long(nullable: false, identify: true)
The used name of the trigger ID_HistoryUnknownMessages_SequenceId is not
allowed because of it's length.
CreateTable(
"HistoryUnknownMessages",
c => new
{
SequenceId = c.Long(nullable: false, identify: true),
EventOccurred = c.DateTime(nullable: false),
Address = c.String(nullable: false, maxLength: 15),
Message = c.String(nullable: false, maxLength: 1000),
})
.PrimaryKey(t => t.SequenceId, name: "PK_HistoryUnknownMessages");
