I want to select some column(a, b) from the table with the specified condition, so, i can do like this: select a, b from mytable where id = (select id from temptable where tname = 'df' ) and stype = 'def' and range = 'afk' !!!!but, I want the result contains a sum(c) and a count value extra, so, I use the sql below: select a, b, (select count(1) from mytable where id = ( select id from temptable where tname = 'df' ) and stype = 'def' and range = 'afk' ), (select sum(c) from mytable where id = ( select id from temptable where tname = 'df' ) and stype = 'def' and range = 'afk' ) from mytable where id = ( select id from temptable where tname = 'df' ) and stype = 'def' and range = 'afk'; can someone help me to make this sql statement above more pretty and more concise? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
