raw
Medoo provides raw expressions for complex and highly customizable queries. Raw expressions also support placeholders to prevent SQL injection, plus shortcut syntax for identifier quoting.
Medoo::raw($query, $map)
query [string]
The raw SQL expression.
map [array] (optional)
Input parameter values for prepared statements.
Syntax
Raw SQL expressions provide a shortcut for quoting identifiers. Use
<name> to mark a column (or table-qualified column), and Medoo handles quoting automatically.
Medoo::raw("AVG(<weight>)")
For Column
You can use a raw object in the
select() column list. The array key becomes the alias in the result.$data = $database->get('account', [
'user_name',
'score' => Medoo::raw('SUM(<age> + <experience>)')
], [
'user_id' => 100
]);
SELECT "user_name", SUM("age" + "experience") AS "score"
FROM "WP_account"
WHERE "user_id" = 100
For Update and Insert Statements
Raw objects can also be used as column values in
insert() and update().$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 Clauses
Raw objects can be used inside the where array for advanced expressions.
$data = $database->select('account', [
'user_name',
'user_id',
], [
'datetime[>=]' => Medoo::raw('DATE_SUB(NOW(), INTERVAL 1 DAY)'),
'ORDER' => Medoo::raw('RAND()'),
'LIMIT' => 10
]);
SELECT "user_name", "user_id" FROM "account" WHERE "datetime" >= DATE_SUB(NOW(), INTERVAL 1 DAY) ORDER BY RAND() LIMIT 10
With Prepared Statement
If raw expressions include values from variables or user input, use prepared placeholders 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 a raw object as the full where clause for advanced filtering.
$data = $database->select('account', [
'user_id',
'email'
],
Medoo::raw('WHERE
LENGTH(<user_name>) > 5
ORDER BY RAND()
LIMIT 10
')
);
SELECT "user_id", "email"
FROM "account"
WHERE LENGTH("user_name") > 5
ORDER BY RAND()
LIMIT 10
