Hello,
i have a question regarding the GREATEST function of mysql.

D = 0, E = 1 and F = 0 and I run a query:

Hi,
You could split the table into two and can avoid code changes by creating a
view which matches what code is looking for.
I think loading few fields vs 254 into memory will make a difference but if
your select statement only have specific fields you want and not the whole
row (and also given
probably want to perform this conversion on your client. There
are JSON parser libraries available for Java, PHP and the like. Cheers,

Hi,
You could use regular expression to do this, here is the example with the
reference site that might help you:
If your data is 'test', 'test0', 'test', '111test', '111'
SELECT * FROM myTable WHERE col1 REGEXP '^[0-9]+$';
Result: '111'
In regex ^ mean begin, and $ - end.
SELECT * FROM
Hi,
In your second query, you seem to have MIN(date_time), but you are talking
about maximum. So your group by query is actually pulling the minimum date
for this recipe.
