我需要在单独的列中从结果中获取匹配的关键字。
表:
| name | description | info | matched |
|---------|-------------------|-----------------|-----------------|
| Event1 | This will be great| great experience|great,experience |
| Event2 | great experience | great thinking |great,experience |
| Event3 | Great match | think |great |
阵列: {很大,经验}
使用这个数组我想要匹配的关键字,如上所示
答案 0 :(得分:0)
这样的事情:
select e.name,
e.description,
(select string_agg(distinct lower(m.word), ',')
from regexp_split_to_table(concat_ws(' ', e.description, e.info), '\s') as m(word)
where lower(m.word) = any(array['great','experience']))
from events e;
但那不会很快
