ThinkPHP视图查询

ThinkPHP视图查询

一、总结

1、这里的视图查询和多表查询很像，当然多表查询的话肯定要支持左右链接查询

2、view：视图的使用，关键字是view

3、sql视图功能支持：thinkphp支持视图，也就是告诉我们，sql里面的视图，存储过程啥的thinkphp这些框架等都支持

二、ThinkPHP视图查询

                            $data=Db::view("goods","id,name,price")

                                               ->view("type",'name tname',"type.id=goods.cid")

                                               ->select();

                            // SELECT `goods`.`id`,`goods`.`name`,`goods`.`price`,type.name tname FROM `goods` `goods` INNER JOIN `type` `type` ON `type`.`id`=`goods`.`cid`

                            $data=Db::view("goods","id,name,price")

                                               ->view("type",'name tname',"type.id=goods.cid","left")

                                               ->select();

                            // SELECT `goods`.`id`,`goods`.`name`,`goods`.`price`,type.name tname FROM `goods` `goods` LEFT JOIN `type` `type` ON `type`.`id`=`goods`.`cid`
