From the above table i want the following

Select distinct OptionName from myTable where ProductID = 709 group by OptionValue

but sql server is giving error on the group by clause and dont know how can i have all the different values grouped to distinct OptionName?

or i just can not ?

the result i want is as follows

[0] => array

    [Color] => array
        [0] => Cobalt test
        [1] => Crimson
        [2] => another color
   [Title] => array
       [0] => Como test
       [1] => Como G2
       [2] => another title

Answer 1

You need to use an aggregate function on the fields (like FIRST(), LAST(), MAX(), AVG() …) you are selecting when you have a GROUP BY-clause. Also, distinct is not necessary when you have GROUP BY. Can you explain what data you want to extract and not only post a faulty query?

EDIT:

SELECT OptionName, OptionValue FROM myTable WHERE ProductID = 709 ORDER BY OptionName ASC

Will produce this:

> OptionName    OptionValue

> Color          another color   
> Title          Como   test    
> Title          Como G2
> Title          another title

Converting to arrays etc. is something you have to do in your application, not with SQL.
