Raw object
Medoo provided a way to use raw expressions for more complex and customizable queries. It also supports data placeholders for preventing SQL injection and optimized syntax without carrying about the quotation.
query [string]
The raw SQL expression.
map (optional) [array]
The array of input parameters value for the prepared statement.
Syntax
The raw SQL expression provides a shortcut for quoting column names, so you don't have to care about the quotation. All you have to do is use <name> to explain this is the column name. Medoo will handle the rest.
Medoo::raw("AVG(<weight>)")
For Column
You can use the raw object to select() the column name parameter. It will be aliased as the key name.
$data = $database->get('account', [
'user_name',
'score' => Medoo::raw('SUM(<age> + <experience>)')
], [
'user_id' => 100
]);
SELECT "user_name", SUM("age" + "experience") AS "score"
FROM "WP_account"
WHERE "user_id" > 100
For Update and Insert Statement
$data = $database->insert('account', [
'user_name' => 'apple',
'user_id' => Medoo::raw('UUID()')
]);
$data = $database->update('account', [
'user_name' => 'apple',
'user_id' => Medoo::raw('UUID()')
], [
'age[>]' => 10
]);
For Where Statement
$data = $database->select('account', [
'user_name',
'user_id',
], [
'datetime' => Medoo::raw('NOW()'),
'ORDER' => Medoo::raw('RAND()'),
'LIMIT' => Medoo::raw('AVG(<age>)')
]);
With Prepared Statement
If you want to use some values from other variables or user post dates for the raw object, you can use a prepared statement to prevent SQL injection.
$today = "2017-05-01";
$database->select('account', [
'user_id',
'user_name'
], [
'datetime' => Medoo::raw('DATE_ADD(:today, INTERVAL 10 DAY)', [
':today' => $today
])
]);
As Where Clause
You can also use raw objects as the where clause for building complex clauses.
$data = $database->select('account', [
'user_id',
'email'
],
Medoo::raw('WHERE
LENGTH(<user_name>) > 5
ORDER BY RAND()
LIMIT 10
')
);
