weekday

My query is somewhat like this: select 1 from dual where :p1_task_date in (sysdate,sysdate+1,sysdate-1) and :p1_task_id is not null This works fine, but I wanted to get next/previous working days (next/previous week days) instead of sysdate+1 and sysdate-1. I tried something like: select next_day(sysdate, to_char(sysdate+1,'DAY')) from dual` but cannot proceed with this :( Please Help!!!! @Tawman's answer will work, but I prefer this method for readability: select sysdate as current_date, case when to_char(sysdate,'D') in (1,6,7) then next_day(sysdate,'Monday') else sysdate+1 end as next

What kind of component is the date

You can get more details from the PHP manual but in a nutshell here are the functions you

In a Postgres 9.1 database, I am trying to generate a series of weeks for a given month but with some constraints. I need all weeks to start on Monday and get cut when they start or end in another month. Example: For February, 2013 I want to generate a series like this: start ------------------------ 2013-02-01 00:00:00+00 2013-02-04 00:00:00+00 2013-02-11 00:00:00+00 2013-02-18 00:00:00+00 2013-02-25 00:00:00+00 The query that I have now looks like this: SELECT GREATEST(date_trunc('week', dates.d), date_trunc('month',dates.d)) as start FROM generate_series(to_timestamp(1359676800),to
