I have 2 Tables
1st Table has 1 Field in it - KEYWORDS, each value / row is unique
2nd Table has multiple fields, one of which is called KEYWORDS, which can contain multiple KEYWORDs, seperated by a comma.

What I want to do is the following :-
- For every record in Table 1 - I want to show how many times the value appears within Table2

The 2 Tables DO NOT have any common Fields which Link the 2 tables - other than the value in Table1 may appear within a Field (along with others) within Table2

eg. Table1 - Keyword1
      Table1 - Keyword2
      Table1 - Keyword3
      Table1 - Keyword4

      Table2 - Keyword3, Keyword4, Keyword1
      Table2 - Keyword1, Keyword2, Keyword3
      Table2 - Keyword1, Keyword3
      Table2 - Keyword2, Keyword3

Result
Keyword1 = 3
Keyword2 = 2
Keyword3 = 3
Keyword4 = 1

try this.
SELECT t1.KEYWORDS, 
       COUNT(*) 
  FROM (Table1 AS t1 
        LEFT JOIN Table2 AS t2 
          ON INSTR(1, t2.KEYWORDS, t1.KEYWORDS, 1) > 0) 
 GROUP BY t1.KEYWORDS 
 ORDER BY t1.KEYWORDS;  

Open in new window

For Keyword3, count is 4.
