Question

I am trying to only grab records that fall in a certain date range. The problem is that the timestamp and the date are stored as a string in the same cell. I want to only grab rows with a date that falls betweed 2013-05-01 and 2013-05-03.

date (stored as string)

2013-05-01T23:19:44
2013-05-02T23:19:40
2013-05-06T23:19:46
2013-05-06T23:15:17

mysql

SELECT * FROM table WHERE date BETWEEN 2013-05-01 AND 2013-05-03

Answer 1

Try

SELECT *
  FROM table1
WHERE STR_TO_DATE(`date`,'%Y-%m-%d') BETWEEN '2013-05-01' AND '2013-05-03'

SQLFiddle

As @FreshPrinceOfSO absolutely correctly noted no index will be used in that case

Answer 2

SELECT * FROM table1 
WHERE STR_TO_DATE(SUBSTRING(`date`,1,10),'%d-%m-%Y') 
    BETWEEN '2013-05-01' AND '2013-05-03'

Answer 3

The string is almost valid syntax for a datetime . Thus, an alternative, if perhaps slower method is to replace the 'T' with a space and then cast it to a datetime .

SELECT * FROM table1 WHERE
  CAST(REPLACE(`date`, 'T', ' ') AS DATETIME) 
  BETWEEN '2013-05-01' AND '2013-05-03';

Answer 4

SELECT * FROM table 
WHERE date('yourdate') BETWEEN date('2013-05-01') AND date('2013-05-03')
