为什么这个查询返回的结果总是比我在我的数据库中实际拥有的结果多，而且还返回错误的结果？
顺便说一句，“inventar”和“evidenta”这两个表通过 ID_M 建立了关系
谢谢你的帮助:D
最佳答案
请测试此查询(我认为您必须在查询中管理'OR'):
<?php
mysql_query("SELECT *
FROM `inventar` i , `evidenta` e
WHERE ( i.`ID_M` = '" . $search . "'
AND i.`ID_M` = e.`ID_M`
)
OR ( (i.`model` LIKE '" . $search . "')
OR (e.`data_intrare` = '" . $search . "')
OR (e.`data_iesire` = '" . $search . "')
OR ( i.`user` LIKE '" . $search . "'
AND i.`user` = e.`user_iesire`
)
OR ( i.`dept` LIKE '" . $search . "'
AND i.`dept` = e.`dept`
)
OR (i.`tip` LIKE '" . $search . "')
OR (i.`COD` like '" . $search . "')
OR (i.`SERIA` LIKE '" . $search . "')
OR (i.`NR_INV` LIKE '" . $search . "')
)"
);
关于php - sql搜索结果太多也有错，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45275587/
