  • mysql query timer for .net

    - by acidzombie24
    Is there something i can use to track how long my mysql queries take? perhaps log them if they take a certain amount of time? or track all queries but only hold the longest query time? using this with C# .NET with ASP.NET. I'd like to use this to occasionally check if my queries are getting slow.

  • Error in computed Field of select Query

    - by Shehzad Bilal
    This Query is giving me an error of #1054 - Unknown column 'totalamount' in 'where clause' SELECT (amount1 + amount2) as totalamount FROM `Donation` WHERE totalamount > 1000 I know i can resolve this error by using group by clause and replace my where condition with having clause. But is there any other solution beside using having clause. If group by is the only solution then I want to know why I have to use group by clause even I havent use any aggregate function thanks.

  • Update multiple table column values using single query

    - by Dave Jarvis
    How would you update data in multiple tables using a single query? In MySQL it would be: UPDATE party p LEFT JOIN party_name n ON p.party_id = n.party_id LEFT JOIN party_details d ON p.party_id = d.party_id LEFT JOIN incident_participant ip ON ip.party_id = p.party_id LEFT JOIN incident i ON ip.incident_id = i.incident_id SET p.employee_id = NULL, c.em_address = '[email protected]', c.ad_postal = 'x', n.first_name = 'x', n.last_name = 'x' WHERE i.confidential_dt IS NOT NULL What is the equivalent SQL statement using Oracle 11g? (Is ANSI SQL possible?) Thank you!

  • Ordering sql query results

    - by user343409
    My sql query gives the columns: product_id (which is an integer) pnl (which is float - can be negative) I get more than 100 rows. I want to filter out the top 40 rows based on abs(pnl). But the results should be ordered by pnl column only and not by abs(pnl). I want to do this for MSSQL 2005. Is there a way to do this?

  • MVC | Linq Update Query | Help!

    - by 109221793
    Hi guys, I'm making modifications to a C# MVC application that I've inherited. I have a database, and for simplicity I'll just focus on the two tables I'm working with for this linq query. Item ItemID Int PK ItemName RepairSelection (Yes or No) RepairID Int FK Repair RepairID Int PK RepairCategory SubmissionDate DateSentForRepair Ok, so ItemID is pretty much the identifier, and the View to display the Repair details goes like this (snippet): <%= Html.LabelFor(x => x.ItemID)%> <%= Html.DisplayFor(x => x.ItemID)%><br /> <%= Html.LabelFor(x => x.Repair.RepairCategory)%> <%= Html.DisplayFor(x => x.Repair.RepairCategory, "FormTextShort")%><br /> <%= Html.LabelFor(x => x.Repair.SubmissionDate)%> <%= Html.DisplayFor(x => x.Repair.SubmissionDate)%><br /> <%= Html.LabelFor(x => x.Repair.DateSentForRepair)%> <%= Html.DisplayFor(x => x.Repair.DateSentForRepair)%><br /> <%= Html.ActionLink("Edit Repair Details", "Edit", new { ItemID= Model.ItemID})%> Here is the GET Edit action: public ActionResult Edit(Int64? itemId) { ModelContainer ctn = new ModelContainer(); var item = from i in ctn.Items where i.ItemID == itemId select i; return View(item.First()); } This is also fine, the GET Edit view displays the right details. Where I'm stuck is the linq query to update the Repair table. I have tried it so many ways today that my head is just fried (new to Linq as you may have guessed). My latest try is here (which I know is way off so go easy ;-) ): [HttpPost] public ActionResult Edit(Int64 itemId, Repair repair, Item item, FormCollection formValues) { if (formValues["cancelButton"] != null) { return RedirectToAction("View", new { ItemID = itemId }); } ModelContainer ctn = new ModelContainer(); Repair existingData = ctn.Repair.First(a => a.RepairId == item.RepairID && item.ItemID == itemId); existingData.SentForConversion = DateTime.Parse(formValues["SentForConversion"]); ctn.SaveChanges(); return RedirectToAction("View", new { ItemID = itemId }); } For the above attempt I get a Sequence Contains No Elements error. Any help or pointers would be appreciated. Thanks guys.

  • Solr query results using *

    - by agentile
    I want to provide for partial matching, so I am tacking on * to the end of search queries. What I've noticed is that a search query of gatorade will return 12 results whereas gatorade* returns 7. So * seems to be 1 or many as opposed to 0 or many ... how can I achieve this? Am I going about partial matching in Solr all wrong? Thanks.

  • MySQL- complex data query in a single statement

    - by yoda
    Hi, Consider the following structure : Ignore the table user_token. Now, imagine that you need to get all the roles related to an user, wich may be through it's related groups or directly related to him. In case the same role appears related to a group and the user directly, the role related to the user will prevail over the role given by the group. Is there any chance this could be done in a single query? Cheers!

  • How to convert map to url query string?

    Do you know of any utility class/library, that can convert Map into URL-friendly query string? Example: I have a map: - "param1"=12, - "param2"="cat" I want to get: param1=12&param2=cat. PS. I know I can easily write it myself, I am just surprised that I cannot find it anywhere (I checked Apache Commons so far).
