两个日期之间的SQL

Question

I have tried researching but can't figure it out. My SQL table has a column of type "date" which structures the data as YYYY-MM-DD. How do I perform an SQL query to search between two dates?

If I change start - end to 1 - 999999999 then it displays all my data, so I know my query is working. I just can't get it to understand my date values.

 <?php $start = '2015-01-01' $end = '2015-12-31' $query = "SELECT * FROM table WHERE (Week BETWEEN $start AND $end)"; ?> 

Answer 1

try to change,

$query = "SELECT * FROM table WHERE (Week BETWEEN $start AND $end)";

to

$query = "SELECT * FROM table WHERE Week BETWEEN '$start' AND '$end'";

and the fields $start and $end should be of the type date

Answer 2

You can do it like

 $start = '2015-01-01';
 $end = '2015-12-31';

$query=  "SELECT * FROM table WHERE Week 
BETWEEN '$start' AND '$end'";

OR

$query= "SELECT * FROM table WHERE Week   
>= '$start'   AND  Week <= '$end'";
