  • MySQLi PHP: Check if SQL INSERT query was fully successful using MySQLi

    - by Jonathan
    Hi, I have this big function that gets a lot of different data and insert it into multiple tables.. Not all the data is always available so not all the SQL INSERT queries are successful. I need to check which SQL INSERT query was fully successful and which wasn't to the do something with this data (like inserting into a log table or similar). Just to give you an example of how I think it can be done: $sql = 'INSERT INTO data_table (ID, column1, column2) VALUES(?, ?, ?)'; if ($stmt->prepare($sql)) { $stmt->bind_param('iss', $varID, $var1, $var2); if ($stmt->execute()) { $success == TRUE; //or something like that } } I'm not completely sure this is the best way and if its always really show if the data was inserted into the table... Any suggestions??

  • Foreign key reference to a two-column primary key

    - by Adam Ernst
    One of my tables has a two-column primary key: CREATE TABLE tournament ( state CHAR(2) NOT NULL, year INT NOT NULL, etc..., PRIMARY KEY(state, year) ); I want a reference to the tournament table from another table, but I want this reference to be nullable. Here's how I might do it, imagining that a winner doesn't necessarily have a tournament: CREATE TABLE winner ( name VARCHAR NOT NULL, state CHAR(2) NULL, year INT NULL ); If state is null but year is not, or vice-versa, the table would be inconsistent. I believe the following FOREIGN KEY constraint fixes it: ALTER TABLE winner ADD CONSTRAINT FOREIGN KEY fk (name, state) REFERENCES tournament (name, state); Is this the proper way of enforcing consistency? Is this schema properly normalized?

  • Breaking the Outlook 2010 e-mail blue quote line for inline responses

    - by Jez
    This has to be the most infuriating regression from Outlook 2003 to 2007. It also exists the same in Outlook 2010, as far as I can tell. When you reply to an HTML e-mail message in Outlook, the quoted text has a blue line down the side, and is usually at the bottom of the message: Now in Outlook 2003, when replying to HTML-formatted messages in Outlook, you used to be able to reply inline quite easily, by getting to the point in the quoted message you wanted to reply to, and pressing the 'decrease indent' button: Since Outlook 2007 (and 2010), they replaced the e-mail editor with Microsoft Word. This means the blue line is implemented in a different way; it uses a blue left border. This makes it tougher to break the line up. After much ado, I found a couple of pages that said that you could remove all formatting by pressing ctrl-Q, which would remove the blue line next to the cursor and allow inline replies: OK, not too bad on the face of it. I can live with that. But here's the kick in the teeth; try sending that mail. I'll send it to myself. What do I receive? This: Outlook 2010 reinstated the blue line, where I had removed it, upon my sending the e-mail! For God's sake! The two pages I linked to above don't seem to address Outlook's reinstating of the blue line upon sending. So, does anyone know how you can actually reply inline in Outlook 2010 (or Outlook 2007) e-mail without the blue line being reinstated? Before anyone says, I do not want to convert the message to plaintext, and I do not want to just indent replies and have to manually build the blue line myself. I want something like the Outlook 2003 behaviour; I reply, Outlook creates the blue line, and I can break it up with inline replies, send it, and my inline formatting stays. My hopes aren't high - Microsoft seem to have gone to some trouble to actively prevent inline replies here, for some reason - but I'd appreciate anyone's insights. Cheers!

  • Entity Relationship diagram - Composition

    - by GigaPr
    Hi, I am implementing a small database(university Project) and i am facing the following problem. I created a class diagram where i have a class Train {Id, Name, Details} And a class RollingStock which is than generalized in Locomotive and FreightWagon. A train is Composed by multiple RollingStock at a certain time(on different days the rolling stock will compose a different train). I represented the relationship train - rolling stock as a diamond filled (UML) but still I have a many to many relationship between the two tables. so i guess i have to create an additional table to solve the many to many relationship train_RollingStock. but how do i represent the Composition? Can i still use the filled diamond? If yes on which side? Thanks

  • general database modeling and django specific modeling

    - by Shreko
    I'm wondering what is the best way to model something like the following. Lets say my company sells metal bars (parameters/fields are: length, profile_type, quantity etc.) of different profiles, where profiles may be pipe(pipe_diameter, wall_thickness) or hollow_rectangle(base, height, wall_thickness), or maybe some other profile with different parameters. Lets say maximum number of profiles would be 12, each profile having between 2-5 parameters. Should everything be in a single table like table_bars: id, length, quantity, profile_type, pipe_diameter, wall_thickness, base, height, etc.) where profile type would be (pipe, rectangle etc.) or should every shape have its own table with its own parameters and in table_bars keep only id, length, quantity profile_type and profile_id) and are there any django specific issues is multiple tables are the best answer? Thanks

  • suggestions for Membership in ASP.NET MVC application

    - by mare
    With this question I am mostly looking for answers from people that have implemented the out-of-the-box ASP.NET membership in their own database - I've set up the tables inside my database and as far as I can see they contain mostly what I need but not everything. I will have the notion of a Firm (Company) to which Users will belong so I will have to associate the aspnet_Users with my Firms table (each user will be a member of exactly one firm). If possible, provide some guidelines how did you do it and what I might run into if I have to modify the table design at some point in the future. Preferably I will be using the default Membership provider. I am having trouble to decide whether to go from scratch or use what ASP.NET already offers.

DBMS is SQL Server 2005. T-SQL solution preferred. Thanks in advance, Dave

  • Report group headings not repeating on every page.

    - by ProfK
    I have an RDLC report with three tables and associated data sets. In my second table, I cannot get the two 'header' rows to repeat on each printed page. When viewed interactively, each table is on its own page and this isn't a problem. When I switch to print layout, e.g. my second table now spans two pages, and the second page gets no header rows. Am I missing a setting or something? ADDED: I do have the 'Repeat Header columns on each page' checked.

  • How to read XML from the internet using a Web Proxy?

    - by Mark Allison
    This is a follow-up to this question: How to load XML into a DataTable? I want to read an XML file on the internet into a DataTable. The XML file is here: http://rates.fxcm.com/RatesXML If I do: public DataTable GetCurrentFxPrices(string url) { WebProxy wp = new WebProxy("http://mywebproxy:8080", true); wp.Credentials = CredentialCache.DefaultCredentials; WebClient wc = new WebClient(); wc.Proxy = wp; MemoryStream ms = new MemoryStream(wc.DownloadData(url)); DataSet ds = new DataSet("fxPrices"); ds.ReadXml(ms); DataTable dt = ds.Tables["Rate"]; return dt; } It works fine. I'm struggling with how to use the default proxy set in Internet Explorer. I don't want to hard-code the proxy. I also want the code to work if no proxy is specified in Internet Explorer.

  • MS SQL Bridge Table Constraints

    - by greg
    Greetings - I have a table of Articles and a table of Categories. An Article can be used in many Categories, so I have created a table of ArticleCategories like this: BridgeID int (PK) ArticleID int CategoryID int Now, I want to create constraints/relationships such that the ArticleID-CategoryID combinations are unique AND that the IDs must exist in the respective primary key tables (Articles and Categories). I have tried using both VS2008 Server Explorer and Enterprise Manager (SQL-2005) to create the FK relationships, but the results always prevent Duplicate ArticleIDs in the bridge table, even though the CategoryID is different. I am pretty sure I am doing something obviously wrong, but I appear to have a mental block at this point. Can anyone tell me please how should this be done? Greaty appreciated!

  • Microsoft Sync Framework - How to reprovision a table (or entire scope) fater schema changes?

    - by Rabbi
    B"H I have already setup Syncing with Microsoft Sync Framework, and now I need to add fields to a table. How do I re-provision the databases? The setup is exceedingly simple: Two sql express 2008 servers The scope includes the entire database Using Microsoft Sync Framework 2.0 Synchronizing by direct access. Using the standard new SqlSyncProvider Do I make the structural changes at both ends? Or do I only change one Server and let Sync Framework somehow propagate the change? Do I need to delete the _tracking tables and/or the stored procedures? How about the triggers? Has anyone been using the Sync Framework? Please help.

  • L2E many to many query

    - by 5YrsLaterDBA
    I have four tables: Users PrivilegeGroups rdPrivileges LinkPrivilege ----------- ---------------- --------------- --------------- userId(pk) privilegeGroupId(pk) privilegeId(pk) privilegeId(pk, fk) privilegeGroupId(fk) name code privilegeGroupId(pk, fk) L2E will not create LinkPrivilege entity for me. So we only have Users, PrivilegeGroups and rdPrivileges entities. PrivilegeGroups and rdPrivileges are many to many relationship. What I need to do is retrieve all code from rdPrivileges table based on a passed in userId. How can I do it? EDIT working code: var acc = from u in db.Users from pg in db.PrivilegeGroups from p in pg.rdPrivileges where u.UserId == userId && u.PrivilegeGroups.PrivilegeGroupId == pg.PrivilegeGroupId select p.Code;

  • WPF - Virtualizing an ItemsControl?

    - by Rachel
    I have an ItemsControl containing a list of data that I would like to virtualize, however VirtualizingStackPanel.IsVirtualizing="True" does not seem to work with an ItemsControl. Is this really the case or is there another way of doing this that I am not aware of? To test I have been using the following block of code: <ItemsControl VirtualizingStackPanel.IsVirtualizing="True" ItemsSource="{Binding Path=AccountViews.Tables[0]}"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBlock Initialized="TextBlock_Initialized" Margin="5,50,5,50" Text="{Binding Path=Name}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> If I change the ItemsControl to a ListBox, I can see that the Initialized function only runs a handful of times (the huge margins are just so I only have to go through a few records), however as an ItemsControl every item gets initialized. I have tried setting the ItemsControlPanelTemplate to a VirtualizingStackPanel but that doesn't seem to help.

  • Tutorials for .NET database app using SQLite

    - by ChrisC
    I have some MS Access experience, and had a class on console c++ apps, now I am trying to develop my first program. It's a little C# db app. I have the db tables and columns planned and keyed into VS, but that's where I'm stuck. I'm needing C#/VS tutorials that will guide me on configuring relationships, datatyping, etc, on the db so I can get it ready for testing of the schema. The only tutorials I've been able to find either talk about general db basics (ie, not helping me with VS/C#), or about C# communications with an existing SQL db. Thank you. (In case it matters, I'm using the open source System.Data.SQLite (sqlite.phxsoftware.com) for the db. I chose it over SQL Server CE after seeing a comparison between the two. Also I wanted a server-less version of SQL because this little app will be on other people's computers and I want to to do as little support as possible.)

  • how to precompile sass with gruntjs?

    - by chovy
    There seem to be a few plugins...and I'm using webstorm file watcher which also precompiles individual files. I think this may not be the best way to setup a watcher. I'm running this command now: sass --no-cache --update --stop-on-error --trace ./app/sass:./app/css It seems to conflict with the webstorm file watch, which appears to be appending everything to base.css. Can someone tell me what exactly this command is doing vs. a sass filewatcher in webstorm? What's the best way to work with sass: precompile my sass to css using a grunt build task and have file watchers while developing? My base.sass looks like this: @charset "UTF-8"; /* DO NOT EDIT FILES IN ./css. See ./sass instead */ @import "page"; @import "modal"; @import "nav"; @import "tables"; @import "forms"; @import "message";

It is probably caused by the foreign key constraint?

  • .DBML file and LINQ to SQL

    - by Rishabh Ohri
    In my DBML file I have mapped some tables and stored procedures, and the stored procedures return type is ISingleResult . T is some mapped table. But I want to take the data into my own created entities rather than LINQ to SQL created entites. The entites created by me are also the same as the mapped table entities and their use lies when we send data across the a web service. So , how can I proceed by creating a wrapper around the DBML file so that I always get data in my own created entites.

So far I have this script that creates the necessary args for bcp. However I can not figure out how to pass the args to bcp. Every time I run the script it just shows the bcp help instead. This must be something really easy that I am not getting. #commands bcp database.dbo.tablename out c:\temp\users.txt -N -t, -U uname -P pwd -S <servername> $bcp_path = "C:\Program Files\Microsoft SQL Server\90\Tools\Binn\bcp.exe" $serverinfo =@{} $serverinfo.add('table','database.dbo.tablename') $serverinfo.add('uid','uname') $serverinfo.add('pwd','pwd') $serverinfo.add('server','servername') $out_path= "c:\Temp\db\" $args = "$($serverinfo['table']) out $($out_path)test.dat -N -t, -U $($serverinfo['uid']) -P $($serverinfo['pwd']) -S $($serverinfo['server'])" #this is the part I can't figure out & $bcp_path $args

  • Is it a Good Practice to Write HTML Using a StringBuilder in my ASP.NET Codebehind?

    - by d3020
    I'm interested to hear from other developers their opinion on an approach that I typically take. I have a web application, asp.net 2.0, c#. What I usually do to write out drop downs, tables, input controls, etc. is in the code behind use StringBuilder and write out something like sb.Append(" I don't find myself using to many .net controls as I typically write out the html in the code behind. When I want to use jQuery or call JavaScript I just put that function call in my sb.Append tag like sb.Append("td...onblur='fnCallJS()'. I've gotten pretty comfortable with this approach. For data access I use EntitySpaces. I'm just kind of curious if this sort of approach is horribly wrong, ok depending on the context, good, time to learn 3.0, etc. I'm interested in learning and was just looking for some input.
