hi friends.

i have a table that i have more than 20 rows on it. i have a query for fetching 20 rows from this table that have a same column. and this 20 rows have a column that for every row it has a value from 1 to 20. for example first row has column 'radif' that its value is 6, second rows radif column has value of 13 and others like this. i want to select a row that has a maximum value of radif column. i do not know maximum number of radif and do not know where it is placed. i tested this my self for 20 rows and with a 'order by radif asc' command ssms return numbers in this order
1-10-11-12-13-14-15-16-17-18-19-2-3-4-5-6-7-8-9.i want to ssms return radif in this format-->

You would need to convert your string to a number to get an ordinal sorting.

thanks.good idea.

1 solution

The trouble is that you have stored your numer as a string - so it uses a strign comparision for everything, and that works on a character-by-character basis. The firts character that is differnet decides the comparison.

The best solution is never to store numeric data as strings; use a numeric field. That way comparisons work properly, and you can useful things like math operations on them.

Failing that, you'd need to convert the strign to an number - and hope like heck that none of them contain "bad" characters...
Will do it temporarily, but seriously - change your DB!
