صياغة WHERE

الشروط الأساسية

$database->select("account", "user_name", [
	"email" => "foo@bar.com"
]);
// WHERE email = 'foo@bar.com'

$database->select("account", "user_name", [
	"user_id" => 200
]);
// WHERE user_id = 200

الشروط المنطقية

الاستخدام الأساسي

$database->select("account", "user_name", [
	"AND" => [
		"user_id[>]" => 200,
		"age[<>]" => [18, 25],
		"gender" => "female"
	]
]);

// يجمع Medoo الشروط باستخدام AND بشكل افتراضي. الاستعلام التالي مكافئ لذلك.
$database->select("account", "user_name", [
	"user_id[>]" => 200,
	"age[<>]" => [18, 25],
	"gender" => "female"
]);

WHERE user_id > 200 AND age BETWEEN 18 AND 25 AND gender = 'female'

$database->select("account", "user_name", [
	"OR" => [
		"user_id[>]" => 200,
		"age[<>]" => [18, 25],
		"gender" => "female"
	]
]);

WHERE user_id > 200 OR age BETWEEN 18 AND 25 OR gender = 'female'

الشروط المتداخلة

$database->has("account", [
	"AND" => [
		"OR" => [
			"user_name" => "foo",
			"email" => "foo@bar.com"
		],
		"password" => "12345"
	]
]);

WHERE (user_name = 'foo' OR email = 'foo@bar.com') AND password = '12345'

نظرًا لأن Medoo يستخدم المصفوفات لوصف الشروط المنطقية، فإن المفاتيح المكررة في نفس المصفوفة ستحل محل بعضها البعض.

// هذا المثال لن يعمل كما هو متوقع.
$database->select("account", '*', [
	"AND" => [
		"OR" => [
			"user_name" => "foo",
			"email" => "foo@bar.com"
		],
		"OR" => [
			"user_name" => "bar",
			"email" => "bar@foo.com"
		]
	]
]);
// [X] SELECT * FROM "account" WHERE ("user_name" = 'bar' OR "email" = 'bar@foo.com')

$database->select("account", '*', [
	"AND #يمكن استخدام التعليقات مع أي شرط منطقي AND أو OR" => [
		"OR #الشرط الأول" => [
			"user_name" => "foo",
			"email" => "foo@bar.com"
		],
		"OR #الشرط الثاني" => [
			"user_name" => "bar",
			"email" => "bar@foo.com"
		]
	]

	("user_name" = 'foo' OR "email" = 'foo@bar.com')

)

علاقات الأعمدة

$database->select("post", [
	"[>]account" => "user_id",
], [
	"post.content"
], [
	// قارِن بين الأعمدة باستخدام معاملات على أسماء الأعمدة المؤهلة بالكامل، مثل [=] و[>] و[<] و[!=].
	"post.restrict[<]account.age"
]);

WHERE "post"."restrict" < "account"."age"

شروط LIKE

// افتراضيًا، تُحاط الكلمة المفتاحية بعلامة % من الجهتين لإجراء مطابقة جزئية.
$database->select("person", "id", [
	"city[~]" => "lon"
]);

WHERE "city" LIKE '%lon%'

مطابقة المجموعات

$database->select("person", "id", [
	"city[~]" => ["lon", "foo", "bar"]
]);

WHERE "city" LIKE '%lon%' OR "city" LIKE '%foo%' OR "city" LIKE '%bar%'

شروط LIKE المنفية

$database->select("person", "id", [
	"city[!~]" => "lon"
]);

WHERE "city" NOT LIKE '%lon%'

شروط LIKE المركبة

$database->select("person", "id", [
	"content[~]" => ["AND" => ["lon", "on"]]

WHERE ("content" LIKE '%lon%' AND "content" LIKE '%on%')

$database->select("person", "id", [

البحث عن النص الكامل

أوضاع البحث

// شرط MATCH.
$database->select("post_table", "post_id", [

		"keyword" => "foo",

WHERE MATCH (content, title) AGAINST ('foo' IN NATURAL LANGUAGE MODE)

التعبيرات العادية

WHERE "datetime" = NOW()

LIMIT و OFFSET

// أعد أول 100 صف.
$database->select("account", "user_id", [
	"LIMIT" => 100
]);

// تخطَّ أول 20 صفاً، ثم أعد الصفوف المئة التالية.
