单个 where ... like 子句中的多行

Question

我正在尝试创建一个搜索表单并尝试在多行/串联行中进行搜索。有没有办法使用类似下面的代码：

$where = "
    WHERE
    (
        s.companyName,
        s.companyName || s.companyType,
        s.companyName || s.companyLocationType,
        s.companyLocationName,
        s.companyLocationName || s.companyLocationType
    ) LIKE (".$val.")
";

或：

$where = "
    WHERE
    (
        s.companyName
        OR s.companyName || s.companyType
        OR s.companyName || s.companyLocationType
        OR s.companyLocationName
        OR s.companyLocationName || s.companyLocationType
    ) LIKE (".$val.")
";

还是我必须那样使用它：

$where = "
    WHERE
        s.companyName LIKE (".$val.")
        OR s.companyName || s.companyType LIKE (".$val.")
        OR s.companyName || s.companyLocationType LIKE (".$val.")
        OR s.companyLocationName LIKE (".$val.")
        OR s.companyName || s.companyLocationType LIKE (".$val.")
";

Answer 1

WHERE (".$val.") in (s.companyName | s.companyType,s.companyName | s.companyLocationType)

等如果您正在寻找完全匹配而不是使用 LIKE，将会起作用。
