Working every day on a large Oracle production database (10g), we noticed that operations like granting an user read privileges on a table creating a trigger on a table lock that table, and invalidate all the cursors insisting on it. This has tremendous consequences if the table is big (> 20 million rows) and many users are working ...
I have a table A which maintains count of total users in Table B. All I care is that the count in Table A is in sync with the number of users in the table B. So, whenever I insert a user in Table B, I want the count to be incremented/decremented depending on insert of user or delete. There are two ways:- a) In case I am inserting the...

I've seen the following pattern: declare @type char(1) if exists (select * from inserted) if ...
Using Perforce, I'd like to be able to reject submits which contain files with Windows line endings (\r\n IIRC, maybe just \r anywhere as really we only want files with Unix line endings). Rather than dos2unix incoming files or similar, to help track down instances where users attempt to submit files with Windows line endings, I'd like ...

It also looks like Foreign Key constraints show up in the pg_trigger table, which I DO NOT want to drop...

I'm trying to find out what is updating the value of a column and i have very little knowledge of the application. At a quick glance I've noticed about 90% of the applications business logic is handled on the database. Needless to say the depth of SP's, functions, and triggers is crazy. I'd like to create a trigger on the table in quest...

In Microsoft SQL Server : I've added an insert trigger my table ACCOUNTS that does an insert into table BLAH based upon the inserted values. The inserts come from only one place, and those happen one at a time.

I have a function that is used as an INSERT trigger. This function deletes rows that would conflict with [the serial number in] the row being inserted. It works beautifully, so I'd really rather not debate the merits of the concept. DECLARE re1 feeds_item.shareurl%TYPE; BEGIN SELECT regexp_replace(NEW.shareurl, '/[^/]+(-[0-9]+\.html)$',...
