What do stored procedures do

To execute a stored procedure on a remote Adaptive Server, you must give the server name. The full syntax for a remote procedure call is:.

The last example works only if pubs 2 is your default database. The database name is optional only if the stored procedure is located in your default database. The owner name is optional only if the Database Owner " dbo " owns the procedure or if you own it. Of course, you must have permission to execute the procedure.

When the procedure is executed, the results of each command are displayed in the order that the statement appears in the procedure. When a create procedure command is successfully executed, the procedure's name is stored in sysobjects , and its source text is stored in syscomments. Stored procedures can serve as security mechanisms, since a user can be granted permission to execute a stored procedure, even if she or he does not have permissions on the tables or views referenced in it or permission to execute specific commands.

The following example retrieves the EmpID which is an auto identity column when a new employee is inserted. Executing the stored procedures with output parameters is bit different.

We must declare the variable to store the value returned by the output parameter. When you try to script the encrypted stored procedure from SQL Server management studio, it throws an error as below.

Like the temporary table, we can create temporary procedures as well. There are two types of temporary procedures, one is a local temporary stored procedure and another one is a global temporary procedure. Local temporary SQL Server stored procedures : These are created with as prefix and can be accessed only in the session where it created.

This procedure is automatically dropped when the connection is closed. Global temporary SQL Server stored procedure: These procedures are created with as prefix and can be accessed on the other sessions as well. To test the syntax, on the Query menu, click Parse.

If an error message is returned, compare the statements with the information above and correct as needed. To create the procedure, from the Query menu, click Execute.

The procedure is created as an object in the database. To run the procedure, in Object Explorer, right-click the stored procedure name HumanResources.

In the Execute Procedure window, enter Margheim as the value for the parameter LastName and enter the value Diane as the value for the parameter FirstName.

Validate all user input. You can also pass parameters to a stored procedure, so that the stored procedure can act based on the parameter value s that is passed. The following SQL statement creates a stored procedure named "SelectAllCustomers" that selects all records from the "Customers" table:.

The following SQL statement creates a stored procedure that selects Customers from a particular City from the "Customers" table:. Setting up multiple parameters is very easy. Just list each parameter and the data type separated by a comma as shown below.
