将数据表传递到存储过程中。有更好的方法吗?

可以在SQL中创建用户定义的表类型。然后,在存储过程中,接受类型为(用户定义的表类型)的参数,并将其值传递给存储过程。

以下是一些例子 http://msdn.microsoft.com/en-us/library/bb675163.aspx :

在SQL中:

CREATE TYPE dbo.CategoryTableType AS TABLE
    ( CategoryID int, CategoryName nvarchar(50) )

然后:

// Assumes connection is an open SqlConnection object.
using (connection)
{
// Create a DataTable with the modified rows.
DataTable addedCategories =
  CategoriesDataTable.GetChanges(DataRowState.Added);

// Configure the SqlCommand and SqlParameter.
SqlCommand insertCommand = new SqlCommand(
    "usp_InsertCategories", connection);
insertCommand.CommandType = CommandType.StoredProcedure;

SqlParameter tvpParam = insertCommand.Parameters.AddWithValue(
    "@tvpNewCategories", addedCategories);
tvpParam.SqlDbType = SqlDbType.Structured;

// Execute the command.
insertCommand.ExecuteNonQuery();
}

否则,您可以选择SQL大容量插入。

我试过了,最好的方法。

enter code here

  Using dbConn As New SqlConnection(connectionStr)
                dbConn.Open()
                countStart = System.Convert.ToInt32(commandRowCount.ExecuteScalar())



                Using bulkcopy As SqlBulkCopy = New SqlBulkCopy(dbConn)
                    bulkcopy.DestinationTableName = "[dbo].[DocumentScan]"
                    Try
                        ' Write from the source to the destination.
                        bulkcopy.WriteToServer(newDataTable)

                    Catch ex As Exception
                        Console.WriteLine(ex.Message)
                    End Try
                    Dim countEnd As Long = _
                  System.Convert.ToInt32(commandRowCount.ExecuteScalar())


                End Using
