It's also possible to set a table prefix:
```php
$db->setPrefix('tablePrefix');
```
Next, prepare your data, and call the necessary methods.
### Insert Query
Simple example
```php
$data = Array ("login" => "admin",
"firstName" => "John",
"lastName" => 'Doe'
)
$id = $db->insert('users', $data);
if($id)
echo 'user was created. Id='.$id;
```
Insert with functions use
```php
$data = array(
$data = Array(
'login' => 'admin',
'active' => true,
'firstName' => 'John',
'lastName' => 'Doe',
'password' => $db->func('SHA1(?)',Array ("secretpassword+salt")),
// password = SHA1('secretpassword+salt')
'createdAt' => $db->now(),
// createdAt = NOW()
'expires' => $db->now('+1Y')
// expires = NOW() + interval 1 year
// Supported intervals [s]econd, [m]inute, [h]hour, [d]day, [M]onth, [Y]ear
);
$id = $db->insert('users', $data)
$id = $db->insert('users', $data);
if($id)
echo 'user was created. Id='.$id;
```
### Select Query
### Update Query
```php
$data = Array (
'firstName' => 'Bobby',
'lastName' => 'Tables',
'editCount' => $db->inc(2),
// editCount = editCount + 2;
'active' => $db->not()
// active = !active;
);
$db->where('id', 1);
if($db->update('users', $data)) echo 'successfully updated';
```
### Select Query
After any select/get function calls amount or returned rows
is stored in $count variable
```php
$users = $db->get('users'); //contains an array of all users
$users = $db->get('users', 10); //contains an array 10 users
$users = $db->get('users'); //contains an Array of all users
$users = $db->get('users', 10); //contains an Array 10 users
```
or select with custom columns set. Functions also could be used
```php
$stats = $db->getOne ("users", null, "sum(id), count(*) as cnt");
$stats = $db->getOne ("users", "sum(id), count(*) as cnt");
echo "total ".$stats['cnt']. "users found";
$cols = Array ("id, name, email");
$users = $db->get ("users", null, $cols);
foreach ($users as $user) {
print_r ($user);
}
if ($db->count > 0)
foreach ($users as $user) {
print_r ($user);
}
```

// Gives: SELECT * FROM users WHERE id >= 50;

$db->where('id', Array('between' => Array(4, 20) ) );
//$db->where('id', Array('not between' => Array(4, 20) ) );

OR CASE
```php
$db->where('firstName','John');
$db->orWhere('firstName','Peter');
$results = $db->get('users');
// Gives: SELECT * FROM users WHERE firstName='John' OR firstName='peter'
```
NULL comparison:
```php
$db->where ("lastName", Array("<=>" => NULL));
$results = $db->get("users");
// Gives: SELECT * FROM users where lastName <=> NULL
```
Also you can use raw where conditions:
```php
$db->where ("id != companyId");
$results = $db->get("users");
```
Or raw condition with variables:
```php
$db->where("id = ? or id = ?", Array(6,2));
$res = $db->get ("users");
// Gives: SELECT * FROM users WERE id = 2 or id = 2;
```
Optionally you can use method chaining to call where multiple times without referencing your object over an over:
```php
$results = $db
->where('id', 1)
->where('title', 'MyTitle')
->where('login', 'admin')
->get('users');
```
