Should be something like this: // enable error reporting for mysqli mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT); // create mysqli object $mysqli = new mysqli(/* fill in your connection info here */); $email = $_POST[’email’]; // might want to validate and sanitize this first before passing to database… // set query $query = “SELECT COUNT(*) FROM users WHERE … Read more
Okay, here is a way to do it: Edited, to fix bug when fetching multiple rows $sql = “SELECT `first_name`,`last_name` FROM `users` WHERE `country` =? AND `state`=?”; $params = array(‘Australia’,’Victoria’); /* In my real app the below code is wrapped up in a class But this is just for example’s sake. You could easily throw … Read more
Prepared statements only. Because nowhere escaping is the same thing. In fact, escaping has absolutely nothing to do with whatever injections, and shouldn’t be used for protection. While prepared statements offer the 100% security when applicable.
Try removing the single quotes from the query string and adding them to the parameter value itself: $pstmt=odbc_prepare($odb_con,”select * from configured where param_name=?”); $res=odbc_execute($pstmt,array(” ‘version'”)); var_dump($res); //bool(true) $row = odbc_fetch_array($pstmt); var_dump($row); //bool(false) The single space character at the beginning of the parameter value is very important–if the space is not there, it will treat the … Read more
a prepared statement allows you to do two things speed up the performance since the database does not need to parse the statement each time bind & escape arguments in the statement so you are save against injection attacks I don’t know exactly where/when Androids SQLite implementation actually uses sqlite3_prepare (afiak not sqlite3_prepare_v2 – see … Read more
To set a timestamp value in a PreparedStatement in UTC timezone one should use stmt.setTimestamp(1, t, Calendar.getInstance(TimeZone.getTimeZone(“UTC”))) The Timestamp value is always UTC, but not always the jdbc driver can automatically sent it correctly to the server. The third, Calendar, parameter helps the driver to correctly prepare the value for the server.
Instead of Date you should use a Timestamp and the setTimestamp method. pratically you have to do something like that: private static java.sql.Timestamp getCurrentTimeStamp() { java.util.Date today = new java.util.Date(); return new java.sql.Timestamp(today.getTime()); } …. preparedStatement.setTimestamp(4,getCurrentTimeStamp());
After calling the execute() method on the Prepared Statement, the id of the insert row will be in the insert_id attribute. $pstm->execute(); $pstm->insert_id;
Prepared statements offer excellent protection against SQL injection. In addition to SQL injection protection, prepared statements offer reduced load on the database server when the same query is to executed multiple times, such as in an INSERT loop. The statement is only compiled once by the RDBMS rather than needing to be compiled each time … Read more
When binding parameters you need to pass a variable that is used as a reference: $var = 1; $stmt->bind_param(‘i’, $var); See the manual: http://php.net/manual/en/mysqli-stmt.bind-param.php Note that $var doesn’t actually have to be defined to bind it. The following is perfectly valid: $stmt->bind_param(‘i’, $var); foreach ($array as $element) { $var = $element[‘foo’]; $stmt->execute(); }
