Question

I have two tables.

First contain list of used words, second keep black list of words which can’t be shown ever.

First table (A) example

+---------------+
| keyword       |
+---------------+
| php           |
| php developer |
| developer     |
| c#            |
+---------------+

Second table (B) example:

+-----------+
| word      |
+-----------+
| developer |
| foo       |
| music     |
+-----------+

I have to show everything from 1st table except rows which fully or partially contain words from second table.
Based on content above, for instance, i should show only two rows
php and c#.

How i can reach the same result with help SQL (very good if it will be one)

I can make only this

select * from A where keyword not in(select word from B);

but it’s strict comparision. it’s not enough to me.

Any advice are welcome.
Thanks.

Answer 1

It would be something like this:

select keyword from A where keyword not in
   (select A.keyword from A
    inner join B on A.keyword like '%' + B.keyword + '%')

You select all the words from A that contain words of B and afterwords you select the other words.
