使用准备好的语句选择其他日期

Question

In the database same date is multiple time there. The table data contain date with time if I use this it is not giving the record that I need to modify. I want 2012-11-21 this date all records. But token_gen_time it contains 2012-11-21 1:00:00 . How can I write query to select depending on date.

SELECT * FROM mias_log
where activity_status='Token Generated' 
AND token_gen_time='2012-11-21 '

Answer 1

You can drop the time from your token_gen_time using the DATE() function to return values matching only the date

SELECT * 
FROM mias_log 
where activity_status='Token Generated' 
  AND Date(token_gen_time) = '2012-11-21'

Answer 2

You can extract the date part with DATE()

SELECT * 
FROM mias_log 
where activity_status = 'Token Generated' 
and date(token_gen_time) = '2012-11-21'

Answer 3

In order to make use of index (if available in token_gen_time), use this

SELECT * 
FROM mias_log 
where activity_status = 'Token Generated' 
and token_gen_time >= '2012-11-21' 
and token_gen_time < '2012-11-22'
