--------------------------------------------------------
Key: DNET-714
URL: http://tracker.firebirdsql.org/browse/DNET-714
Project: .NET Data provider
Issue Type: Bug
Components: ADO.NET Provider, Entity Framework support
Affects Versions: 5.5.0.0
Environment: FB3, .NET 4.6.2, Win7 64, EF6.1.3
Reporter: Scot Lunsford

null.

WHERE (("SCENARIOID" = :p1) AND ("ROWVERSION" = :p2))
