select table.a , table.b, {expression(a,b)} from table where a = 'a' and b = 'b' and {expression(a,b)} = {condition}
select * from (select table.a , table.b, {expression(a,b)} as exp from table where a = 'a' and b = 'b') res where res.exp = {condition}
Здравствуйте, Алксандр Бенедский, Вы писали:
АБ>select table.a , table.b, {expression(a,b)} from table where a = 'a' and b = 'b' and {expression(a,b)} = {condition}
АБ>select * from (select table.a , table.b, {expression(a,b)} as exp from table where a = 'a' and b = 'b') res where res.exp = {condition}
