Another important feature of My Sqli is the Prepared Statements, it allows us to write query just once and then it can be executed repeatedly with different parameters.Prepared Statements significantly improves performance on larger table and more complex queries.The queries are parsed separately by the server, making it resilient to malicious code injection.The code below uses Prepared statement to fetch records from the database.To insert multiple rows at once, include multiple lists of column values, each enclosed within parentheses and separated by commas.Sometimes you want to know how many records have been inserted, updated or deleted, you can use Syntax in My Sql query.

Here is the code for my Edit page: query($sql) or die(mysql_error()); $query=getenv(QUERY_STRING); parse_str($query); //$ud_title = $_POST['Title']; //$ud_pub = $_POST['Publisher']; //$ud_pubdate = $_POST['Publish Date']; //$ud_img = $_POST['Image']; ?

My Sqli and PDO are improved version and offer an object-oriented API and number of enhancement over the regular My Sql extension.

These extensions are much faster, efficient and totally secure against SQL injections.
