As in other DBMS, procedures are widely used in Firebird optimizing processes and improving performance of the database in the execution of more complex commands. Using the following syntax quickly you can create them:
CREATE PROCEDURE [Procedure name]([IN Parameters])
Note that there is a specific space for the declaration of variables, before the beginning and end of the command block, so if you need to use variables other than those passed as parameter is required to use this space.
As a practical example we will create a simple procedure that returns a query product.
CREATE PROCEDURE sp_Product_Query()
SELECT Cod_Prod, Name
We will also create a procedure to insert using information passed as parameters.
CREATE PROCEDURE sp_Product_Insert( Namep Varchar(200) )
INSERT INTO product (Name)
In web applications, for example, the use of procedures is very common because most of the interactions with the database are done using them.
With the popularization of the Firebird development environments is important to understand its functioning, especially in the development of web applications. Discover the advantages of working with Firebird and PHP on our official site and understand better this scenario.
