I have tried AND and a nested NOT EXISTS as stated in the mysql manual. Nothing worked.

  • How to limit select items with L2E/S?

    - by orlon
    This code is a no-go var errors = (from error in db.ELMAH_Error select new { error.Application, error.Host, error.Type, error.Source, error.Message, error.User, error.StatusCode, error.TimeUtc }).ToList(); return View(errors); as it results in a 'requires a model of type IEnumerable' error. The following code of course works fine, but selects all the columns, some of which I'm simply not interested in: var errors = (from error in db.ELMAH_Error select error).ToList(); return View(errors); I'm brand spanking new to MVC2 + L2E, so maybe I'm just not thinking in the right mindset yet, but this seems counter-intuitive. Is there an easy way to select a limited number of columns, or is this just part of using an ORM?

    I'm deleting selected rows from both table in MYSQL, the two tables have foreign keys. delete d,b from A as b inner join B as d on b.bid=d.bid where b.name like '%xxxx%'; MYSQL complains about foreign keys even though I'm trying to delete from both tables: Error: Cannot delete or update a parent row: a foreign key constraint fails (yyy/d, CONSTRAINT fk_d_bid FOREIGN KEY (bid) REFERENCES b (bid) ON DELETE NO ACTION ON UPDATE NO ACTION) what's the best solution here to delete from both table?

  • Faster way to dump mysql

    - by japancheese
    This may be a dumb question, but I was just watching a screencast on MySQL replication, and I learned that a master database doesn't send SQL over to a slave for replication, it actually sends data over in binary, which makes importing extremely fast. I started wondering, "if a database can export and import binary, why do mysqldumps / imports take so long?" Is there a way to get mysql to dump a database in binary in a similar fashion to speed up that process as well?

  • Is an object still connected to a list after FirstOrDefault?

    - by Cynthia
    Here's my code: Event thisEvent = (from i in list where (i.eventID == eventID) select i).FirstOrDefault(); if (thisEvent != null) { thisEvent.eventResolved = resolved; thisEvent.eventSequence.Add(item); } "list" is a collection of IEnumerable, i.e. IEnumerable<Event> list; What I'm wondering is: after creating thisEvent using FirstOrDefault, is thisEvent still connected to list? In other words, when I change the two properties, eventResolved and eventSequence, is "list" actually changed, or is thisEvent just some totally disconnected copy of an item in "list"?

  • Django - Add rows to MySQL database

    - by yeenow123
    So I already have a database setup with a few columns and a few rows already inserted in. I'm trying to create a view that you would just input information into a form and press Submit, then a row would be added to the MySQL database with the information you just typed in. I believe you can do this with admin, but I would like to try without admin and I'm not sure if this is possible? I've been using the MySQL commandline to add rows as of now..

  • What doesn't MySQL do? [closed]

    - by sean riley
    When using MySQL 5.1 Enterprise after years of using other database products like Sybase, Infomix, DB2; I run into things that MySQL just doesn't do. For example, it can only generate an EXPLAIN query plan for SELECT queries. What are the other things I should watch out for?

  • Trigger on database using a web application and a winform application

    - by Michael
    Hello all, Situation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how. Can anyone help me with this?
