Hi, I'm just curious about the reasons of the design of 'DO' statement so that it is not able to return result of the SELECT in its body.
References: https://www.postgresql.org/docs/current/static/sql-do.html http://stackoverflow.com/questions/14652477/how-to-perform-a-select-query-in-a-do-block With some former experience with MsSQL server, where 'complex' script is executed easily and straightforward without any 'wrapping', like this dummy-one ... DECLARE @a int; DECLARE @b int; ... select @a + @b as "a+b" ... every time I need to execute some one-time-through-away complex code in PostgreSQL which returns rowset I'm disappointed - this has to be wrapped into normal 'temp' function which I have to delete all the time in current session, thus making an anonymous 'DO' statement use-less in 95% of my use-cases. So ... may someone know good reasons for such inconvenient design of 'DO' statement? Thanks.
