視圖查詢可以實現不依賴數據庫視圖的多表查詢，并不需要數據庫支持視圖，例如： ~~~ Db::view('User','id,name') ->view('Profile','truename,phone,email','Profile.user_id=User.id') ->view('Score','score','Score.user_id=Profile.id') ->where('score','>',80) ->select(); ~~~ 生成的SQL語句類似于： ~~~ SELECT User.id,User.name,Profile.truename,Profile.phone,Profile.email,Score.score FROM think_user User INNER JOIN think_profile Profile ON Profile.user_id=User.id INNER JOIN think_socre Score ON Score.user_id=Profile.id WHERE Score.score > 80 ~~~ > 注意，視圖查詢無需調用`table`和`join`方法，并且在調用`where`和`order`方法的時候只需要使用字段名而不需要加表名。 默認使用INNER join查詢，如果需要更改，可以使用： ~~~ Db::view('User','id,name') ->view('Profile','truename,phone,email','Profile.user_id=User.id','LEFT') ->view('Score','score','Score.user_id=Profile.id','RIGHT') ->where('score','>',80) ->select(); ~~~ 生成的SQL語句類似于： ~~~ SELECT User.id,User.name,Profile.truename,Profile.phone,Profile.email,Score.score FROM think_user User LEFT JOIN think_profile Profile ON Profile.user_id=User.id RIGHT JOIN think_socre Score ON Score.user_id=Profile.id WHERE Score.score > 80 ~~~ 可以使用別名： ~~~ Db::view('User',['id'=>'uid','name'=>'account']) ->view('Profile','truename,phone,email','Profile.user_id=User.id') ->view('Score','score','Score.user_id=Profile.id') ->where('score','>',80) ->select(); ~~~ 生成的SQL語句變成： ~~~ SELECT User.id AS uid,User.name AS account,Profile.truename,Profile.phone,Profile.email,Score.score FROM think_user User INNER JOIN think_profile Profile ON Profile.user_id=User.id INNER JOIN think_socre Score ON Score.user_id=Profile.id WHERE Score.score > 80 ~~~ 可以使用數組的方式定義表名以及別名，例如： ~~~ Db::view(['think_user'=>'member'],['id'=>'uid','name'=>'account']) ->view('Profile','truename,phone,email','Profile.user_id=member.id') ->view('Score','score','Score.user_id=Profile.id') ->where('score','>',80) ->select(); ~~~ 生成的SQL語句變成： ~~~ SELECT member.id AS uid,member.name AS account,Profile.truename,Profile.phone,Profile.email,Score.score FROM think_user member INNER JOIN think_profile Profile ON Profile.user_id=member.id INNER JOIN think_socre Score ON Score.user_id=Profile.id WHERE Score.score > 80 ~~~
