[SQL] parsing audit table

Hi everyone, I'm a bit lazy, or actually in a bit of a crunch. I added an audit recording a few months ago, but never really used it much, but today I'm seeing a bunch of suspicious activity by one user. Does someone have any function to quickly parse this data? I followed this: http://wik

[SQL] which is better: using OR clauses or UNION?

Hi, I have a query hitting a table of 25 million rows. The table has a text field ('identifier') which i need to query for matching rows. The question is if i have multiple strings to match against this field I can use multiple OR sub-statements or multiple statements in a UNION. The UNION see

Additional information: If I use the following query: select "time", extract(epoch from (date 'now' - integer '30')), extract(epoch from (date 'now')) from ticket_change The first row looks like this: Bigint, double precision, double precision 128609061500;131085;1313442000 Thanks, Jan

Re: [SQL] bigint and unix time

Hi and thanks again. I use the following query but it returns me 0 rows (it should return more): SELECT ticket, "time", author, field, oldvalue, newvalue FROM ticket_change where "time" BETWEEN extract(epoch from (date 'now' - integer '30')) AND extract(epoch from (date 'no

Hi Adrain and thank you, Trac 0.12 uses microseconds as time value. What do you suggest? Thanks, Janiv. -Original Message- From: Adrian Klaver [mailto:adrian.kla...@gmail.com] Sent: Monday, August 15, 2011 17:14 To: Janiv Ratson Cc: pgsql-sql@postgresql.org Subject: Re: [SQL] bigint and

Hi Viktor, thanks for your email, gave that a try, but the lower(identifier) LIKE lower('BUGS001884677') OR still comes in quicker than the IN approach thanks adam On 16 Aug 2011, at 12:56, Viktor Bojović wrote: > hi Adam, > im not sure which is faster/slower but, possibly you can sp
