sorry poor question title, i'm not sure if there's name i'm trying do. i have query such following: select a, b, c, (d + e - f) computedvalue, (select sum(column1) table2) d, (select sum(column2) table3) e, (select sum(column3) table4) f, table1 = 1 so, in other words, use integer values returned subqueries compute value. can in php this: $computedvalue = $row['d'] + $row['e'] - $row['f']; but i'm wondering if it's possible in query itself? when tried got following error: error!: sqlstate[42s22]: column not found: 1054 unknown column 'd' in 'field list' you can't use column aliases in clauses of same query, including in select-list. seems puzzling many sql developers, that's standard sql. but can use derived table subquery this: select *, (d + e - f) computedvalue ( select a, b, c, (select sum(column1) table2) d, (select sum(column2) table3) e, (select sum(c...

(i can't make table changes because other columns have zero's null values. 1 column needs zeros display). for both of these problems php being used display results. edit: code i'm using display results. top 1 needs not show .0 bottom 1 needs show zero. length:</b> %sft' . php_eol, $row2['length']) inversions:</b> %s' . php_eol, $row2['inversions']) i believe sneaky trick if add 0 end of number, removes .0000 etc. example: $number = 150.00 $number = $number + 0; //should echo 150 $other_number = 150.500; $other_number += 0; //shou...
