使用单引号将implode函数中的变量换行

Question

我试图在implode函数内使用数组运行查询。

$dosages = implode(" AND CONCAT(prescription,'-',dosage) =",$doses); 
$q=$this->db->query("SELECT account_num 
        FROM ( 
        SELECT account_num, CONCAT(prescription,'-',dosage) as script 
        FROM ci_prescription_history 
        )a 
        WHERE script=".implode(' AND script=',$doses)); 

MySQL在“where子句”中一直说“未知列'Advair'”。我只是想知道是否有可能换用单引号破灭函数内部的变量，因此，当它被解析它所读出这样的

SELECT account_num 
FROM (SELECT account_num, CONCAT(prescription,'-',dosage) as script 
FROM ci_prescription_history 
)a 
WHERE script='Advair-230/21' AND script='Advair-250/50' 

Answer 1

是的，你需要将引号添加到您的查询和implode()，像这样：

$q=$this->db->query("SELECT account_num 
       FROM ( 
       SELECT account_num, CONCAT(prescription,'-',dosage) as script 
       FROM ci_prescription_history 
       )a 
       WHERE script='" . implode("' AND script ='", $doses)) . "'";

编辑 这里是我做过什么来解决它

foreach ($accounts as $account) { 
    $q=$this->db->query("SELECT account_num 
    FROM ( 
    SELECT account_num, CONCAT(prescription,'-',dosage) as script 
    FROM ci_prescription_history 
    )a 
    WHERE script='".implode("' OR script ='",$doses)."' AND account_num=$account"); 
}
