Reusability: The statement is parsed once, and can be efficiently executed multiple times with different parameter values. Improved security: The database can perform more optimizations since it knows more about the query in advance. You prepare a statement with PDO::prepare(), bind parameters usin...
The equivalent of EXEC (MSSQL Server) is Prepared Statements. e.g.: DELIMITER $$ DROP PROCEDURE IF EXISTS `sptest`$$ CREATE PROCEDURE `sptest`() BEGIN PREPARE stmt1 FROM 'SELECT "ok"'; EXECUTE stmt1; DEALLOCATE PREPARE stmt1; END$$ DELIMITER ; call sptest(); ...
Instead of assembling a query string, preparestatement can be a good defence against SQL injection, because parameter values (transmitted later using a different protocol) need not be correctly escaped. If the original SQL statement template is not derived from external input, SQL injection is not...
SQL provides several pre-built query commands that can be used to retrieve or manipulate data in a database, as shown in Figure 1. Figure 2. Commands SQL users can use to make database queries. Note that SQL andMySQLare not the same, as the latter is a software extension that uses SQ...
the denormalization and ensure data consistency. If a custom implementation is used, the database administrator and application programs are responsible for data consistency. To add denormalized tables as part of the database architecture design, some DBMSes like MySQL use a create view statement. ...
