You can run any types of SQL STATEMENTS through the mysql_query() FUNCTION. It takes the SQL statement as a STRING and returns different types of data depending on the SQL statement type and execution status:
• Returning FALSE, if the execution failed.
• Returning a result set object, if the execution is successful on a SELECT statement or other statement returning multiple rows of data.
• Returning TRUE, if the execution is successful on other statements.
Here is a good EXAMPLE of running a SQL statement with the mysql_query() function:
<?php
include "mysql_connection.php";
$sql = 'SELECT sysdate() FROM dual';
$rs = mysql_query($sql, $con);
$row = mysql_fetch_array($rs);
print("Database current time: ". $row[0] ."\n");
mysql_close($con);
?>
