Question:
i have some data at DB like:
qty item id date 0001-0500 abcd 1 2010-06-22 0001-0500 abcd 2 2010-06-22 0001-0500 abcd 3 2010-06-22 i want some script can make them order by date and show result :
qty : 500 (it means 500-1=500,number 1 read 1-1 = 0) item : abcd id : 3 (counting from 1 until 3) date :2010-06-22 qty item id date 500 abcd 3 2010-06-22 i have tried like this:
'SELECT qty, item, COUNT(*) FROM inspec GROUP BY date'; before use the code above,i still confuse to make changes at :
qty 0001-0500 0001-0500 =>result become:qty : 500 (it means 500-1=500,number 1 read 1-1 = 0) 0001-0500
Solution:1
Sorting and counting can be (and I'd say usually are) done at the database level, using SQL. Otherwise, there are language constructs that can do the heavy lifting for you, again, called sort and count.
If you're using MySQL, the tutorial is a good place to start learning. For PHP, you might find this book helpful.
Solution:2
i have tried like this:
'SELECT item, COUNT(*) FROM inspec GROUP BY date'; If you want qty, shouldn't you SELECT it as well?
'SELECT item, COUNT(*), qty FROM inspec GROUP BY date'; Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
