sql server - access unkown columns of a table and insert them into a new one -
i have table like:
item1 item2 item3 item4... itemn 1 2 3 4... n
if need calculus variables lets powers , sqrt item1,item3, , insert in column 1 of new table, , same operations item2 , item4 , insert in column 2 of new table,... like:
new table column1 column2 column3 .. columnsn-1 columnsn item1*item3 item2*item4 item3*item5 .. itemn-1*item1 itemn *item2
but column names variable (aka different tables) dont know how accomplish , values of specific columns, please me?
this way extract name , order of column:
select name, colorder syscolumns id = (select id sysobjects name = [tablename])
you can use manipulate data refering order in table instead of name
