查询语言.sql
函数原型
本功能特别适合用于调试 SQL,大家可以这样子用。
public function sql($bFlag = true);
用法如下
/*
Array
(
[0] => SELECT `test`.* FROM `test` ORDER BY `test`.`create_at` DESC LIMIT 1
[1] => Array
(
)
[2] =>
[3] => 5
[4] =>
[5] => Array
(
)
)
*/
Db::table('test')->
sql(true)->
latest()->
getOne();
/*
Array
(
[0] => delete from test where id = ?
[1] => Array
(
[0] => 22
)
)
*/
Db::sql(true)->
delete('delete from test where id = ?', [22]);
// 等效
Db::delete('delete from test where id = ?', [22], true);
例外 getOne 等也支持快捷
/*
Array
(
[0] => SELECT `test`.* FROM `test` ORDER BY `test`.`create_at` DESC LIMIT 1
[1] => Array
(
)
[2] =>
[3] => 5
[4] =>
[5] => Array
(
)
)
*/
Db::table('test')->
latest()->
getOne(true);
/*
