sql - How do I transform table- see example? -
if suggests better question title, change it, that's best come with.
i using sql server 2005
is there way transform table 'table_1' 'table_2' using sql.
edit: don't want create new table, want represent in query 'table_2'
table_1:
b 1 true 2 false 4 true 7 false 9 true 10 false
table_2:
x y z 1 2 true 2 4 false 4 7 true 7 9 false 9 10 true
the reason want if have table_3:
table_3:
id m 3 b 4 c 8
i query against table_2 (transformed table_1) this:
select table_3.id table_3 table_2 m between x , y , z = true
i'll answer following questions head of time: 1. can not change table design, nor did design table. 3. have reason not process on client side c# or language.
thanks
try self-join:
select t1.a, min(t2.a), t1.b table_1 t1 inner join table_1 t2 on t2.a > t1.a group t1.a, t1.b
