Retrieving Autogenerated IDs with PreparedStatements
When dealing with database operations, retrieving the auto-generated ID associated with an inserted record can be crucial for record tracking. While the Statement.RETURN_GENERATED_KEYS flag works well with standard statements, it encounters issues when using prepared statements.
However, there is a solution:
String sql = "INSERT INTO table (column1, column2) values(?, ?)";
stmt = conn.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
stmt.executeUpdate(); // Update the database
ResultSet rs = stmt.getGeneratedKeys(); // Retrieve the generated keys
if (rs.next()) {
long auto_id = rs.getLong(1); // Get the auto-generated ID
}
The above is the detailed content of How to Retrieve Auto-Generated IDs with PreparedStatements?. For more information, please follow other related articles on the PHP Chinese website!

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
