It won't work because MySQL doesn't count null values.
It depends.
count(FieldName) will not count NULL values
count(*) will, because it counts rows, not values.

Hi Octavian,

Hi all,
I have a table where I have something like this:
| abc |
| abc |
| xxx |
| null |
| null |
| null |
I want to count these lines to give the result 5, meaning a distinct count
for values which are not null, and counting all the null values.
This means 1 for "abc", one for "xxx", and 3 for null values.
Can you tell me what sql query should I use for counting this?
Thank you.
