Using Stored Procedures

Stored procedures offer many advantages in data-driven applications. Using stored procedures, database operations can be encapsulated in a single command, optimized for best performance, and enhanced with additional security. While a stored procedure can be called by simply passing the stored procedure name followed by parameter arguments as an SQL statement, using the Parameters collection of the ADO.NET Command object enables you to more explicitly define stored procedure parameters as well as to access output parameters and return values.
To call a stored procedure, set the CommandType of the Command object to StoredProcedure. Once the CommandType is set to StoredProcedure, you can use the Parameters collection to define parameters, as in the following example.
Note The OdbcCommand requires that you supply the full ODBC CALL syntax when calling a stored procedure.
