SQL：字段OR字段2喜欢％entry％

Question

是否有一种更简单/更有效的方式来执行以下WHERE条件：

WHERE (Field LIKE %entry% OR Field2 LIKE %entry%)
AND (Field LIKE %entry2% OR Field2 LIKE %entry2%)

Answer 1

请同时参考以下链接 ：

SELECT  *
FROM    mytable
WHERE   MATCH(filed, field2) AGAINST ('entry' IN NATURAL LANGUAGE MODE)

Answer 2

AND (Field LIKE %entry2% OR Field2 LIKE %entry2%)

这部分是

(Field LIKE %entry% OR Field2 LIKE %entry%)

您可以忽略它。

Answer 3

您可以这样做：

where concat_ws(' ', field1, field2) like '%entry%' and
      concat_ws(' ', field1, field2) like '%entry2%'

性能应大致相同。
