insert 插入

insert

插入数据到表中

• table [string]

  表名.

• data [array]

  插入到表里的数据.

$last_user_id = $database->insert("account", [    "user_name" => "foo",    "email" => "foo@bar.com",    "age" => 25]);

插入ID

如果你想要获取最后插入行的ID,你需要单独调用 id()方法

$database->insert("account", [	"user_name" => "foo",	"email" => "foo@bar.com",	"age" => 25]);$account_id = $database->id();

序列化数组

默认情况下，你要将数组插入会被序列化serialize(), 也可以使用 JSON json_encode().

$database->insert("account", [	"user_name" => "foo",	"email" => "foo@bar.com",	"age" => 25,	"lang" => ["en", "fr", "jp", "cn"] // => 'a:4:{i:0;s:2:"en";i:1;s:2:"fr";i:2;s:2:"jp";i:3;s:2:"cn";}']);$database->insert("account", [	"user_name" => "foo",	"email" => "foo@bar.com",	"age" => 25,	"lang [JSON]" => ["en", "fr", "jp", "cn"] // => '["en","fr","jp","cn"]']);

类型自动检测

Medoo将在插入之前自动检测数据类型，并将其优化以存储到数据库中。

class Foo {	var $bar = "cat";	public function __wakeup()	{		$this->bar = "dog";	}}$object_data = new Foo();$fp = fopen($_FILES[ "file" ][ "tmp_name" ], "rb");$database->insert("account", [	// String value	"user_name" => "foo",	// Integer value	"age" => 25,	// Boolean value	"is_locked" => true,	// Array value	"lang" => ["en", "fr", "jp", "cn"],	// Array value encoded as JSON	"lang [JSON]" => ["en", "fr", "jp", "cn"],	// Object value	"object_data" => $object_data,	// Large Objects (LOBs)	"image" => $fp]);

多条数据插入

可以同时插入多条数据.

$database->insert("account", [	[		"user_name" => "foo",		"email" => "foo@bar.com",		"age" => 25,		"city" => "New York",		"lang [JSON]" => ["en", "fr", "jp", "cn"]	],	[		"user_name" => "bar",		"email" => "bar@foo.com",		"age" => 14,		"city" => "Hong Kong",		"lang [JSON]" => ["en", "jp", "cn"]	]]);

PDOStatement

insert()返回的是PDOStatement对象,你可以通过它获取更多信息

$data = $database->insert("account", [	"user_name" => "foo",	"email" => "foo@bar.com",	"age" => 25]);// Returns the number of rows affected by the last SQL statementecho $data->rowCount();// Read more: http://php.net/manual/en/class.pdostatement.php

使用 SQL 函数

在一些特殊的情况下,您可能需要使用SQL函数来处理数据。在字段前加入#号即可

$last_user_id = $database->insert("account", [    "user_name" => "bar",    "#uid" => "UUID()"]);
