Question

I hav the next query in SQL:
SELECT id FROM student WHERE DATE LIKE ‘%$inputdate’
the inputDate is in the next format: 2010.08.03
I also want to change the date of the date, by increasing the day in a week (+7).

I try this:

SELECT id
FROM student
WHERE DATE LIKE '%$inputdate'
     OR DATE Like '%CAST(RIGHT("2012-11-03", 2)AS INT) + 7;

But it gives me SQL syntax error. How can I write it correctly?

Answer 1

since you are using MySQL, make use of DATE() function

SELECT id
FROM student
WHERE DATE(`DATE`) = DATE(inputdate) OR 
      DATE(`DATE`) = DATE(DATE_ADD(DATE(inputdate),INTERVAL 7 DAY))
