In a large system with a quick turnover of database connections, this automatic reuse can save CPU cycles and network bandwidth. NET doesn't include a connection-pooling mechanism. NET providers do implement some form of connection pooling. In the case of the SQL Server and Oracle providers, this connection pooling mechanism is written entirely in managed code. In the case of the OLE DB and ODBC providers, this connection pooling depends on a lower level and has a few limitations. Most providers enable connection pooling automatically.

Are easy to maintain, because they are stored separately from the application code. NET application that uses it. • Add an extra layer of indirection, potentially allowing some database details to change without breaking your code. For example, a stored procedure can remap field names to match the expectations of the client program. • Reduce network traffic, because SQL statements can be executed in batches. Of course, stored procedures aren't perfect. Most of their drawbacks are in the form of programming annoyances: • Using stored procedures in a program often involves importing additional database-specific details (such as parameter data types) into your code.

4 Deriving Parameters So far, the stored procedure examples suffer in one respect: they import numerous database-specific details into your code. Not only do you need to hardcode exact parameter names, but you need to know the correct SQL Server data type, and the field length for any text data. One way to get around these details is to use a CommandBuilder class. This class is used with DataSet updates (which we'll consider in Chapter 5), but it also is useful when dealing with stored procedures.
