Understand with Example
The Tutorial illustrate an example from 'PHP SQL Script'. To make use of sql query in PHP, we create sql_script.php begins with <?php and end with ?>. The <?php enclosed variable con which is assigned to the mysql_connect ( ) function that accept the parameter like "local host", "user" and password to execute the SQL query in PHP. We create a MySQL database which consists of a table "emp_counter" with three column that is id of integer type, name of varchar type , reset_counter of datetime type. We insert a values ('1', 'sandeep', 'SYSDATE()' ) in the table. The Select statement is used to return the records details from table 'emp_counter'. Finally the print is used to print the successful insertion of values into the table 'emp_counter' database.
Source Code of sql_script.php
<?php $mysql_db = "test"; $mysql_user = "root"; $mysql_pass = "root"; $con = mysql_connect("localhost", $mysql_user, $mysql_pass); mysql_select_db($mysql_db, $con); $drop_table = "DROP TABLE if exists emp_counter "; mysql_query($drop_table, $con); $create_query = "CREATE TABLE emp_counter (id INT NOT NULL AUTO_INCREMENT, name VARCHAR(250), reset_counter DATETIME, PRIMARY KEY(id))"; mysql_query($create_query, $con); print("Table Creation for <b>emp_counter</b> successful!<p>"); $insert = "INSERT into emp_counter VALUES (1, 'sandeep', SYSDATE())"; mysql_query($insert, $con); print("Inserted new counter successfully for this page"); ?>
