Hello all, I have a (probably dumb) question. My table "temperatura" has two fields described bellow.
mysql> describe temperatura; +-------------+----------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------------+----------+------+-----+---------+-------+ | datetime | datetime | YES | | NULL | | | temperatura | float | YES | | NULL | | +-------------+----------+------+-----+---------+-------+ 2 rows in set (0.00 sec) When I try to select rows with floats, the result is an empty set. For example: mysql> select datetime,temperatura from temperatura where datetime="2002-02-08 09:30:00"; +---------------------+-------------+ | datetime | temperatura | +---------------------+-------------+ | 2002-02-08 09:30:00 | 15.8 | +---------------------+-------------+ 1 row in set (0.00 sec) ----------------------------> got one row :) mysql>select datetime,temperatura from temperatura where datetime="2002-02-08 09:30:00" and temperatura=15.8; Empty set (0.00 sec) ----------> same thing but with the temperatura value, gives me an empy set :( When I try to select another row but the temperatura field has an integer this is what happens: mysql> select datetime,temperatura from temperatura where datetime="2002-01-25 09:40:00"; +---------------------+-------------+ | datetime | temperatura | +---------------------+-------------+ | 2002-01-25 09:40:00 | 16 | +---------------------+-------------+ 1 row in set (0.00 sec) -----------> got one row :) mysql> select datetime,temperatura from temperatura where datetime="2002-01-25 09:40:00" and temperatura=16; +---------------------+-------------+ | datetime | temperatura | +---------------------+-------------+ | 2002-01-25 09:40:00 | 16 | +---------------------+-------------+ 1 row in set (0.00 sec) --------------> It works now :/ Does anyone have an idea why this happens? How can I select float numbers?
