我正在SQL query数据库表中保存,因此无论是否有更多记录输入数据库,都要保存要使用的条件.
是否有用于存储Query语句的正确数据类型和语法.我已经设置了数据类型,VARCHAR(1055)我认为这就足够了.是否有一个MySQL function确保文本正确保存,引用并保持单个字符串.
更新:保存查询的原因
我们允许系统用户基于系统的其他用户创建联系人详细信息列表,因此他们使用表单创建查询,以选择具有执行类型的所有用户.
然后将上述查询保存在数据库中,这样即使在执行作业类型中添加了新用户,在发送通信时也会包含其联系人详细信息.
我认为这是最好的方式......你有什么想法吗?

所以我查看了App\Company.php,但那里没有字段列表。
然后我查看迁移,但我必须遍历每个迁移才能找到可用的字段。
所以作为最后的手段,我打开一个数据库浏览器来查找模型中的字段。
有没有更简单的方法来了解模型中存在哪些字段?
