A less widely-known capability of TVPs—yet arguably their most compelling facet—is the ability to marshal an entire set of rows across the network, from your ADO. NET client to your SQL Server 2008 database, with a table-valued parameter.
Add(new object ); using (var conn = new Sql Connection("Data Source=.; Initial Catalog=My Db; Integrated Security=True;")) stored procedure on the server.COLLATE Specifies the new collation for the altered column.If not specified, the column is assigned the default collation of the database.The new Table-Valued Parameter (TVP) feature is perhaps the most significant T-SQL enhancement in SQL Server 2008. Many people have already discovered how to use this feature for passing entire sets of rows with a typed schema definition along from one stored procedure to another on the server. The data type of columns included in an index cannot be changed unless the column is a varchar, nvarchar, or varbinary data type, and the new size is equal to or larger than the old size.
A column included in a primary key constraint, cannot be changed from NOT NULL to NULL. For more information about valid scale values, see Precision, Scale, and Length (Transact-SQL).Transact-SQL Syntax Conventions Is the name of the table to be altered.If the table is not in the current database or is not contained by the schema owned by the current user, the database and schema must be explicitly specified.This is something that has not been previously possible using either table variables or temp tables, although temp tables can of course be shared between multiple stored procedures executing on the same connection. Conveniently, TVPs can be passed freely between stored procedures and user-defined functions (UDFs) on the server. ALTER COLUMN Specifies that the named column is to be changed or altered.
