Procedural style:
Object oriented style (property):
mysqli {
int errno ;
}
Returns the last error code for the most recent MySQLi function call that can succeed or fail.
Client error message numbers are listed in the MySQL
errmsg.h
header file, server error message numbers
are listed in mysqld_error.h
.
In the MySQL source distribution you can find a complete list of error
messages and error numbers in the file
Docs/mysqld_error.txt
.
Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()
<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
if (!$mysqli->query("SET a=1")) {
printf("Errorcode: %d\n", $mysqli->errno);
}
/* close connection */
$mysqli->close();
?>
<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
if (!mysqli_query($link, "SET a=1")) {
printf("Errorcode: %d\n", mysqli_errno($link));
}
/* close connection */
mysqli_close($link);
?>
The above example will output:
Errorcode: 1193
