  • How do I select from a stored procedure in Sybase?

    - by Nick Fortescue
    My DBA has constructed me a stored procedure in a Sybase database, for which I don't have the definition. If I run it, it returns a resultset with a set of columns and values. I would like to SELECT further to reduce the rows in the result set. Is this possible? From this question it seems like I could insert the results into a temporary table, but I'm not sure I've got permissions to do this. Is there any way I can SELECT certain rows, or if not, can someone give me example code for simulating with a temporary table?

  • Grabbing Just The Top Entry From A LINQ Query

    - by Soo
    I basically have a lot of poorly designed code to do something that, I'm sure, can be done far more elegantly. What I'm trying to do is grab the last date from a database table. var Result = from a in DB.Table orderby a.Date descending select new {Date = a}; foreach(var Row in Result) { LastDate = Row.Date.Date; break; } Basically, there's a foreach loop that is designed to run only once. Crappy code! What's a "best practice" way to accomplish the same thing?

  • related categories - database design

    - by mike
    Hello! I'm looking for a little database design advice... I have a spreadsheet with a few columns in it. Column 1 being a list of categories and the rest being related categories(to the category in column 1). I'm trying to figure out what the best way to setup the tables would be... My thought so far is to have a table that just lists the categories then have a table with 2 columns that holds the id of the category and the id of a related category.... Would this be the best way to do this? Any better ideas?

  • How to retrieve ID of button clicked within usercontrol on Asp.net page?

    - by Shawn Gilligan
    I have a page that I am working on that I'm linking multiple user controls to. The user control contains 3 buttons, an attach, clear and view button. When a user clicks on any control on the page, the resulting information is "dumped" into the last visible control on the page. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default" MasterPageFile="DefaultPage.master" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %> <%@ Register tagName="FileHandler" src="FileHandling.ascx" tagPrefix="ucFile" %> <asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server"> <asp:UpdatePanel ID="upPanel" UpdateMode="Conditional" runat="server"> <ContentTemplate> <table> <tr> <td> <ucFile:FileHandler ID="fFile1" runat="server" /> </td> <td> <ucFile:FileHandler ID="fFile2" runat="server" /> </td> </tr> </table> </ContentTemplate> </asp:UpdatePanel> </asp:Content> All file handling and processing is handled within the control, with an event when the upload to the file server is complete via a file name that was generated. When either button is clicked, the file name is always stored internal to the control in the last control's text box. Control code: <table style="width: 50%;"> <tr style="white-space: nowrap;"> <td style="width: 1%;"> <asp:Label runat="server" ID="lblFile" /> </td> <td style="width: 20%;"> <asp:TextBox ID="txtFile" CssClass="backColor" runat="server" OnTextChanged="FileInformationChanged" /> </td> <td style="width: 1%"> <%--<asp:Button runat="server" ID="btnUpload" CssClass="btn" Text="Attach" OnClick="UploadFile"/>--%> <input type="button" id="btnUpload" class="btn" tabindex="30" value="Attach" onclick="SetupUpload();" /> </td> <td style="width: 1%"> <%--<asp:Button runat="server" ID="btnClear" Text="Clear" CssClass="btn" OnClick="ClearTextValue"/>--%> <input type="button" id="btnClearFile" class="btn" value="Clear" onclick="document.getElementById('<%=txtFile.ClientID%>').value = '';document.getElementById('<%=hfFile.ClientID%>').value = '';" /> </td> <td style="width: 1%"> <a href="#here" onclick="ViewLink(document.getElementById('<%=hfFile.ClientID%>').value, '')">View</a> </td> <td style="width: 1%"> <asp:HiddenField ID="hfFile" runat="server" /> </td> </tr> </table> <script type="text/javascript"> var ItemPath = ""; function SetupUpload(File) { ItemPath = File; VersionAttach('<%=UploadPath%>', 'true'); } function UploadComplete(File) { document.getElementById('<%=txtFile.ClientID%>').value = File.substring(File.lastIndexOf("/") + 1); document.getElementById('<%=hfFile.ClientID%>').value = File; alert('<%=txtFile.Text %>'); alert('<%=ClientID %>') } function ViewLink(File, Alert) { if (File != "") { if (File.indexOf("../data/") != -1) { window.open(File, '_blank'); } else { window.open('../data/<%=UploadPath%>/' + File, '_blank'); } } else if (Alert == "") { alert('No file has been uploaded for this field.'); } } </script>

  • Does database affect classes?

    - by satyanarayana
    I had created one class User and UserDAOImpl class for querying DB using class User. As there is one table to be queried, these two classes are sufficient for me. What if there is a case where new fields are to be added to that one table is to be divided into 3 tables( user_info, user_profile and user_address) to store user? As new fields are added, I need to change classes User and UserDAOImpl, it seems these two are not sufficient. It seems database changes affect my classes. In this case, do I need to divide class User into 3 classes as tables are changes? Can any one suggest me how can I solve this without making too many changes?

  • Display only file name in FileUpload control

    - by Jagd
    I have a webpage in asp.net 3.5 that uses the FileUpload control. When a user clicks on the "Browse" button (which is part of the control) the control displays a file select popup (dialog box). When the user selects the file which they wish to upload, by default the full path to the file is shown in the textbox (which is also part of the control); however, I wish for it to only display the file name and not the full path. Anyone know of a slick and easy way to do this?

  • T-SQL Self Join in combination with aggregate function

    - by Nick
    Hi, i have the following table. CREATE TABLE [dbo].[Tree]( [AutoID] [int] IDENTITY(1,1) NOT NULL, [Category] [varchar](10) NULL, [Condition] [varchar](10) NULL, [Description] [varchar](50) NULL, CONSTRAINT [PK_Tree] PRIMARY KEY CLUSTERED ( [AutoID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO the data looks like this: INSERT INTO [Test].[dbo].[Tree] ([Category] ,[Condition] ,[Description]) VALUES ('1','Alpha','Type 1') INSERT INTO [Test].[dbo].[Tree] ([Category] ,[Condition] ,[Description]) VALUES ('1','Alpha','Type 1') INSERT INTO [Test].[dbo].[Tree] ([Category] ,[Condition] ,[Description]) VALUES ('2','Alpha','Type 2') INSERT INTO [Test].[dbo].[Tree] ([Category] ,[Condition] ,[Description]) VALUES ('2','Alpha','Type 2') go I try now to do the following: SELECT Category,COUNT(*) as CategoryCount FROM Tree where Condition = 'Alpha' group by Category but i wish also to get the Description for each Element. I tried several subqueries, self joins etc. i always come to the problem that the subquery cannot return more than one record. The problem is caused by a poor database design which i cannot change and i run out of ideas to get this done in a single query ;-(

  • Easy plugin or procedure for sqlserver Management Studio to script row inserts.

    - by Patrick Karcher
    I've never been able to find a good script or plugin for sql server Management Studio (2005 and or 2008) for a very common scripting need: specifying a few/all rows in a table and scripting their insert. You can guess my story: I've got some configuration data in my dev db and I need to script it for deployment to UAT and then production. I've found a few cludgy systems in the past, that were more trouble than they were worth. I need something free and unobtrusive. Once I find it I'll share it with the other 20 developers in my shop who are annoyed by this. Aren't we all annoyed by this by the way? What is the best, easiest, free, way to specify a few/all rows in a table and get a script their insert?

  • Are conditional subqueries optimized out, if the condition is false?

    - by Tobias Schulte
    I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out? We are using mysql, mssql and oracle. Is there a difference between these regarding the above?

  • MySQL storage engine dilemma

    - by burntblark
    There are two MySQL database features that I want to use in my application. The first is FULL-TEXT-SEARCH and TRANSACTIONS. Now, the dilemma here is that I cannot get this feature in one storage engine. It's either I use MyIsam (which has the FULL-TEXT-SEARCH feature) or I use InnoDB (which supports the TRANSACTION feature). I can't have both. My question is, is there anyway I can have both features in my application before I am forced to make a choice between the two storage engines.

  • Is it possible to implement a lightweight database using Blackberry Persistance options?

    - by Tobias
    First I would like to explain why I want to use alternate Blackberry Persistance options rather than a Blackberry database itself, say SQLite. The reason is that the application i'm designing, I want it to be used in all the previous versions of Blackberry rather than just the ones having OS 5.0 or greater. Now, coming back to the actual question, I have got a database that I want to replicate to be used in the Blackberry application. The database has 8 tables and each table has approximately 12 different columns. One of the table has 1000 rows. Now if I was to implement this DB for a Blackberry application , keeping in mind that it will work on all the versions of Blackberry, what would be the best way to implement it?

  • retrieving data from memcache

    - by Adnan
    Hello, I am starting to learn the benefits of memcache, and would like to implement it on my project. I have understood most of it, such as how data can be retrieved by a key and so on. Now I get it that I can put a post with all of its details in memcache and call the key POST:123, that is OK, and I can do it for each post. But how to deal with the case when I query the table posts to get the list of all posts with their titles. Can this be done with memcache, or should this always be queried from the table?

    I tried following this reference and this is now my domain's code: class SnbrActVector { long nid String term double weight static mapping = { version false nid index:'Nid_Idx' } static constraints = { term(blank:false) } } What I want is to do is to add an index key for 'nid' column. I dropped the existing table and run the app again so the table is then recreated. However, when i check for list of indices, I can't see a 'Nid_Idx', only available is 'PRIMARY'. Do I have to manually create the index and name it 'Nid_idx in my mysql database? Thanks.

  • One-to-many relationship related to many tables

    - by Andrey
    I have a scenario where: there are two (or more) tables that represent independent items. lets say Users and Companies Both of these tables need addresses stored. Each one can have one or more address In a normal 1 to many scenario Addresses table woudl just have a UserId or a CompanyId creating a normal 1 to many relationship. In this case i have a few approaches i can think of the Addresses table could have both a UserId and a CompanyId and only one would be used for each record. 2 keys could be used ObjectId and ObjectType So Object id would have a UserId or a CompanyId, and ObjectType woudl be User or Company Create an ObjectTable and add ObjectId to Users and Companies. Addresses would then have an OjbectId I do not really like any of these solutions. i am wondering what is the best approach here. On another note i will most likely user linqtosql for my data access layer.
