I want to know whats VFP9 equivalent to mySQL 'NOT IN'.
To give you the exact purpose. I have two tables and I want to display all the numbers in table1 which don't have any occurrence in table2.
TABLE1
1
2
3
4
5
6
7
8
9
10
TABLE 2
2
3
4
8
9
RESULT:
1
5
6
7
10
I have my mySQL code written:
SELECT * FROM table1 WHERE table1.row1 NOT IN (SELECT row2 FROM table2)
Now this code wont run in vfp9, seem it did not recognize NOT
or is there a flaw to my code. Any Idea.
Try LEFT JOIN
instead:
SELECT t1.*
FROM table1 AS t1
LEFT JOIN table2 AS t2 ON t1.row1 = t2.row2
WHERE t1.row1 IS NULL;
