问题描述

我有两个具有相关数据的表,我想从一个表中选择另一表中不存在的所有记录,以及相关表上的其他一些条件,如下所示(123仅用于说明目的) :

I have two tables with related data, and I want to select all the records from one table which do not exist in the other table, plus some other criteria on the related table, as follows (123 is just for illustration purposes):

TABLE A
    ID
    SOMETHING

TABLE B
    TABLE_A_ID
    TABLE_C_ID
    SOMETHING

我的查询直接针对数据运行,如下所示

My query, run directly against the data, would be as follows

SELECT A.SOMETHING 
    FROM A 
    WHERE A.ID NOT IN (
        SELECT 
            B.TABLE_A_ID AS ID 
            FROM B 
            WHERE TABLE_C_ID = 123
    );

如何在Zend中运行它?

How can I run this in Zend?

推荐答案

您可以使用$db->query()运行直接sql.您的只是:

You can run direct sql, using $db->query(); yours would simply be:

$results = $db->query("SELECT A.SOMETHING 
FROM A 
WHERE A.ID NOT IN (
    SELECT 
        B.TABLE_A_ID AS ID 
        FROM B 
        WHERE TABLE_C_ID = ?
)", $id);

编辑:要回答是否可以使用对象符号来完成,是的:

EDIT: To answer whether this can be done with the object notation, yes:

$sub_select = $zdb->select()
                  ->from("b", array("table_a_id AS id"))
                  ->where("table_c_id = ?", 'a');
$select = $zdb->select()
              ->from("a", array("something"))
              ->where("id NOT IN ?", $sub_select);
print $select->__toString();

给予

SELECT `a`.`something` FROM `a`
WHERE (id NOT IN
    (SELECT `b`.`table_a_id` AS `id` FROM `b` WHERE (table_c_id = 'a')))
