What does SqlDbType.Structured mean?

问题:

From msdn website I get the following:

A special data type for specifying structured data contained in table-valued parameters.

It seems my code works with it and without it (pushing table to DB using stored procedure).

Can someone explain what does it do - I didn't understand it from the definition.

回答1:

In SQL Server, you can define stored procedures and you can pass tables as parameter. This is then called a table valued parameter.

When you are programming in C#, you can pass such a table-valued parameter to the database by using the SqlDbType.Structured constant.
