  • MySQL Triggers to Disable A User Account

    - by Mike D
    I am trying to create a MySQL Trigger to disable someone's account if they have logged in to the site 3 times. I have tried to create this trigger using the following code, but it is not setting is_active to 0 no matter what times_logged_in is. Any help would be appreciated. CREATE TRIGGER updateTrigger AFTER UPDATE ON users FOR EACH ROW BEGIN UPDATE users SET is_active=0 WHERE NEW.is_code=1 AND NEW.times_logged_in>=3 AND NEW.user_id=user_id; END;

  • Simulating MySQL's ORDER BY FIELD() in Postgresql

    - by Peer Allan
    Hello all, Just trying out Postgresql for the first time, coming from MySQL. In our Rails application we have a couple of locations with SQL like so: SELECT * FROM `currency_codes` ORDER BY FIELD(code, 'GBP', 'EUR', 'BBD', 'AUD', 'CAD', 'USD') DESC, name ASC It didn't take long to discover that this is not supported/allowed in Postgresql. Does anyone know how to simulate this behaviour in Postgres or do we have to pull to sorting out into the code? Thanks Peer

  • Query MySQL with unicode char code.

    - by Ben
    Hi, I have been having trouble searching through a MySQL table, trying to find entries with the character (UTF-16 code 200E) in a particular column. This particular code doesn't have a glyph, so it doesn't seem to work when I try to paste it into my search term. Is there a way to specify characters as their respective code point instead for a query? Thanks, -Ben

  • MySQL Select names with last names ending with certain letter

    - by Brian
    I have a MySQL database with a field Name which contains full names. To select all people with last names ending in a particular letter, let's say A for this example, I use the following query: SELECT * FROM db WHERE Name LIKE '% A%'. However, this also selects users who have a middle name starting with A. Is there anyway to alter this query so that only a last name ending in A will be selected?
