问题
Has anybody experimented with these. Is this supported?
回答1:
Table Value parameters aren't supported yet in LINQ to SQL. There's a few posts about this on Microsoft's MSDN forums:
DbType.Structured not available
SQL Server 2k8.User Defined Table Type. Mapping between DbType 'Structured' and Type 'System.Object'
The second link refers to Entity Framework, but the underlying issue is the same.
回答2:
I actually had to try this myself. :0
It does not seem to be supported. I get this error when adding a stored procedure using a tvp parameter into the dbml file
DBML1005: Mapping between DbType 'Structured' and Type 'System.Object' in Parameter 'TVP' of Function 'dbo.spTestTableTypeParm' is not supported
Sad but true, I thought this could be a killer feature of sql 2008 and linq2sql
