1. query() for insert

<?php
// Insert into the database.
$db->query("INSERT INTO users (id, name, email) VALUES (NULL,'justin','[email protected]')");

2. query() for update

<?php
// Update the database.
$db->query("UPDATE users SET name = 'Justin' WHERE id = 2");

3. get_var()

<?php
// Get one variable from the database and print it out.
$var = $db->get_var("SELECT count(\*) FROM users");

echo $var;

4. get_row()

<?php
// Get one row from the database and print it out.
$user = $db->get_row("SELECT name,email FROM users WHERE id = 2");

// Access data using object syntax.
echo $user->name;
echo $user->email;

5. get_results()

<?php 
// Select multiple records from the database and print them out.
$users = $db->get_results("SELECT name, email FROM users");
foreach ( $users as $user ) {
  // Access data using object syntax.
  echo $user->name;
  echo $user->email;
}

6. get_col()

<?php
// Get 'one column' (based on column index) and print it out.
$names = $db->get_col("SELECT name, email FROM users", 0)

foreach ( $names as $name )  {
 echo $name;
}

7. get_col() in foreach

<?php
// Same as above ‘but quicker’
foreach ( $db->get_col("SELECT name, email FROM users", 0) as $name ) {
  echo $name;
}

8. debug()

<?php
// Enable debug
$db->debugOn();
// Run a query
$users = $db->get_results("SELECT name, email FROM users");
// Display last query and all associated results.
$db->debug();

9. varDump()

<?php
// Display the structure and contents of any result(s) .. or any variable
$results = $db->get_results("SELECT name, email FROM users");

$db->varDump($results);

10. Print full schema

<?php
// Map out the full schema of any given database and print it out.
$db->select("my_database");

foreach ( $db->get_col("SHOW TABLES",0) as $table-name ) {
  $db->debug();
  $db->get_results("DESC $table-name");
}

$db->debug();
