Hi, I have used the below code
<?php
$con = mysql_connect("localhost","tst","start123");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("tst", $con);
$result = mysql_query("select Server,Service from MDServersToServices limit 5");
echo "<table border='1'>
<tr>
<th>Server</th>
<th>Service</th>
</tr>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['Server'] . "</td>";
echo "<td>" . $row['Service'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysql_close($con);
?>
Output is only
Server service
Note: There is no data retrieved from that table.
I hope that you can clear now

mysqli_stmt_sqlstate
MYSQLI_STMT_SQLSTATE(3) 1 MYSQLI_STMT_SQLSTATE(3)
mysqli_stmt::$sqlstate - Returns SQLSTATE error from previous statement operation
Object oriented style
SYNOPSIS
string$mysqli_stmt->sqlstate ()
DESCRIPTION
Procedural style
string mysqli_stmt_sqlstate (mysqli_stmt $stmt)
Returns a string containing the SQLSTATE error code for the most recently invoked prepared statement function that can succeed or fail.
The error code consists of five characters. '00000' means no error. The values are specified by ANSI SQL and ODBC. For a list of possible
values, see http://dev.mysql.com/doc/mysql/en/error-handling.html.
PARAMETERS
o $
stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3).
RETURN VALUES
Returns a string containing the SQLSTATE error code for the last error. The error code consists of five characters. '00000' means no
error.
NOTES
Note
Note that not all MySQL errors are yet mapped to SQLSTATE's. The value HY000 (general error) is used for unmapped errors.
EXAMPLES
Example #1
Object oriented style
<?php
/* Open a connection */
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
$mysqli->query("CREATE TABLE myCountry LIKE Country");
$mysqli->query("INSERT INTO myCountry SELECT * FROM Country");
$query = "SELECT Name, Code FROM myCountry ORDER BY Name";
if ($stmt = $mysqli->prepare($query)) {
/* drop table */
$mysqli->query("DROP TABLE myCountry");
/* execute query */
$stmt->execute();
printf("Error: %s.
", $stmt->sqlstate);
/* close statement */
$stmt->close();
}
/* close connection */
$mysqli->close();
?>
Example #2
Procedural style
<?php
/* Open a connection */
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %s
", mysqli_connect_error());
exit();
}
mysqli_query($link, "CREATE TABLE myCountry LIKE Country");
mysqli_query($link, "INSERT INTO myCountry SELECT * FROM Country");
$query = "SELECT Name, Code FROM myCountry ORDER BY Name";
if ($stmt = mysqli_prepare($link, $query)) {
/* drop table */
mysqli_query($link, "DROP TABLE myCountry");
/* execute query */
mysqli_stmt_execute($stmt);
printf("Error: %s.
", mysqli_stmt_sqlstate($stmt));
/* close statement */
mysqli_stmt_close($stmt);
}
/* close connection */
mysqli_close($link);
?>
The above examples will output:
Error: 42S02.
