阅读更多关于 What permission do I need to use an SQL Server Table Valued Parameter (TVP) as a stored proc parameter?

问题 I'm using SQL Server 2008 R2 and I've created a TVP that I want to use as a parameter to a stored proc but I get a message saying that it can't be found or I don't have permission. I can use the TVP in a script or in the body of the stored proc, but when I try to use it as a parameter I get the error. Any thoughts? Edit: For clarification, the error I'm getting is on the creation of the stored proc 回答1: In order for a caller to use a PROC with a table valued parameter, you'll need to

How can I use a Table-Valued Parameter to insert multiple rows and then return their IDs?

阅读更多关于 How can I use a Table-Valued Parameter to insert multiple rows and then return their IDs?

问题 In my application, I have a large of number (100+) of rows that I need to insert into the database. Once they get inserted into the database, I need to insert their children, which have a foreign key reference back to the children. I'm wondering if there's a way to write a stored procedure that can insert all of those rows and return their IDs back to my application? 回答1: You have tagged your question with table-value-parameters - you can pass one these to the stored procedure for inserting

Accessing stored procedures with robconery / massive?

阅读更多关于 Accessing stored procedures with robconery / massive?

问题 Another great article by Rob on the Massive ORM. What I haven't been able to find is references on how to access stored procedures. SubSonic had some issues with the overhead of using ActiveRecords, so I preferred to do data access with stored procedures, still using the SubSonic ORM. What I haven't yet seen is outright support for things like SQL Server's TVP's in an ORM, so I modified SubSonic (shameless plug) to support them. Is it possible to access SQL Server sprocs with Massive.

Problems with table-value parameter performance

阅读更多关于 Problems with table-value parameter performance

问题 I don't know whether this is an issue with how I'm using them or Microsoft's implementation, but SQL 2008 table-value parameters are painfully slow. Generally if I need to use a TVP it's because I've got lots of records - currently they appear to be unusably slow for anything more than the fewest records. I'm calling them in .Net like this: // get the data DataTable data = GetData(); com.CommandText = "sprocName" // create the table-value parameter var tvp = com.Parameters.AddWithValue("data"

Has anybody experimented with these. Is this supported? 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. 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

Binding empty list or null value to table valued parameter on a stored procedure (.net)

阅读更多关于 Binding empty list or null value to table valued parameter on a stored procedure (.net)

问题 I have created a stored procedure that takes a table valued parameter that is a table with a single column of type int. The idea is to simply pass a list of ids into the store procedure and allow the sp to work with the data. However, in the case where there is no data to pass in, I am encountering problems (things work correctly when I have data). I am converting a List to an IEnumerable, and binding that to the table valued parameter for the sp. I have tried to bind an empty List, which
