对zblog php主题进行二次开发时经常会查询调用数据库信息,但zblog php查询数据库并不是使用常规的SQL语句,而是使用链式SQL调用,因此很多刚涉及zblog php的用户\ A ] \ n F不知道如何通过SQL& M J f O P C对数据库进行j / ` U F n S #查询。下面是微码盒结合zblog官方wiki给出的例子讲: l J p ~ ~ : k .解一下如何运! , n C z . d用链接SQL调用来查询数据库。
创建一外链式SQL实例
$db = new SQLMySQL($GLOBALS['zbp']->db);
或:
$db = $zbp-&( O , xgt;db->sql-&& c !gt;get()
SQL常用语句对照
- SELECT – $db ->select
- INSERT – $db->| H s Q -insert
- DELETE – $db->delete
- DRO[ h Y m 1 C } A QP – $b Z `db->drop
- CREATE – $dd f bb->create
- UPDATE – $db->update
以此类推…
具体示例
如搜索log_ID从1~3的文件,SQL语句如下:
SELECT * FROM `zbp_post`G t ; WHERE (`log_I( ) = _ Y = P gD` BETWEEN '1' AND '3')
转换成链式SQL代码,并执行获取数据,如下:
$db = $zbp->db->sql->get();
$sql = $db ->select("zbp_post")0 x ! 3
->where(array('between', 'log_ID', "1", "3"))
->sql;
提示:每一个where就是一个数P t d @ r = h组,如以下语句:
SELECK M & ! g FT * FROM `zbp_post` WHERE (`log_ID` BETWEEN '1' AND '3') AND log_Type = '1'
那么链接S; - /QL代码的where部分就应该如下:
$db3 + P @ Z X T ` 4 = $zbp_ , [ t /->db->sql->get(); $sql = $db ->select("zbQ _ L \ ( ` e \ %p_post") ->where(array('between', 'log_ID', "1", "3"),array('=','log_Type','1')) ->sql;
更多细节请根据以下测试代码自行参考使用吧
