Hello Christopher,

First select:
The results are just right what you want in your SELECT.
You have 5 different values in COLUMN1 and your select returns them.
>From second column SELECT gets first value for each value of first
column.
Second select:
SELECT col1, IF(count(*)!=count(col2),NULL,'BAD')
FROM table1
GROUP BY col1;
This ONLY works EXACLTY for the case you submitted.
Please note that your example is wrong (I think). 3 should also return
NULL, shouldn't it?
