  • How do I flip a column in mysql that has data structured: 'last name, first name'?

    - by ggg
    I want to create a new column in a MYSQL table that has Fn Ln instead of Ln, Fn. Most of my data is printed Fn Ln. Another idea is to incorporate a string function each time there is an output (php based) but that seems to waste resources. Finally, I couldn't find the syntax (loop or foreach) for my php function anyway. Here is the working php function that I got from a previous post: $name = "Lastname, Firstname"; $names = explode(", ", $name); $name = $names[1] . " " . $names[0];

  • Which layer should create DataContext?

    - by Kevin
    I have a problem to decide which layer in my system should create DataContext. I have read a book, saying that if do not pass the same DataContext object for all the database updates, it will sometimes get an exception thrown from the DataContext. That's why i initially create new instance of DataContext in business layer, and pass it into data access layer. So that the same datacontext is used for all the updates. But this lead to one design problem, if i wanna change my DAL to Non-LinqToSQL in future, i need to re-write the code in business layer as well. Please give me some advice on this. Thanks. Example code 'Business Layer Public Sub SaveData(name As String) Using ts AS New TransactionScope() Using db As New MyDataContext() DAL.Insert(db,name) DAL.Insert(db,name) End Using ts.Complete() End Using End Sub 'Data Access Layer Public Sub Insert(db as MyDataContext,name As string) db.TableAInsert(name) End Sub

  • How to make comment reply query in MYSQL?

    - by Prashant
    I am having comment reply (only till one level) functionality. All comments can have as many as replies but no replies can have their further replies. So my database table structure is like below Id ParentId Comment 1 0 this is come sample comment text 2 0 this is come sample comment text 3 0 this is come sample comment text 4 1 this is come sample comment text 5 0 this is come sample comment text 6 3 this is come sample comment text 7 1 this is come sample comment text In the above structures, commentid, 1 (has 2 replies) and 3 (1 reply) has replies. So to fetch the comments and their replies, one simple method is first I fetch all the comments having ParentId as 0 and then by running a while loop fetch all the replies of that particular commentId. But that seems to be running hundreds of queries if I'll have around 200 comments on a particular record. So I want to make a query which will fetch Comments with their replies sequentially as following; Id ParentId Comment 1 0 this is come sample comment text 4 1 this is come sample comment text 7 1 this is come sample comment text 2 0 this is come sample comment text 3 0 this is come sample comment text 6 3 this is come sample comment text 5 0 this is come sample comment text I also have a comment date column in my comment table, if anyone wants to use this with comment query. So finally I want to fetch all the comments and their replies by using one single mysql query. Please tell me how I can do that? Thanks

  • How can I speed up queries against tables I cannot add indexes to?

    - by RenderIn
    I access several tables remotely via DB Link. They are very normalized and the data in each is effective-dated. Of the millions of records in each table, only a subset of ~50k are current records. The tables are internally managed by a commercial product that will throw a huge fit if I add indexes or make alterations to its tables in any way. What are my options for speeding up access to these tables?

  • Synonym for "Many-to-Many" relationship (relational databases)

    - by Byron
    What's a synonym for a "many-to-many" relationship? I've finished writing an object-relational mapper but I'm still stumped as to what to name the function that adds that relation. addParent() and addChild() seemed quite logical for the many-to-one/one-to-many and addSuperclass() for one-to-one inheritance, but addManyToMany() would sound quite unintuitive to an object-oriented programmer. addSibling() or addCousin() doesn't really make sense either. Any suggestions? And before you dismiss this as a non-programming question, please remember that consistent naming schemes and encapsulation are pretty integral to programming :)

  • Postgres update rule returning number of rows affected

    - by Lithium
    I have a view table which is a union of two seperate tables (say Table _A and Table _B). I need to be able to update a row in the view table, and it seems the way to do this was through a 'view rule'. All entries in the view table have seperate id's, so an id that exists in table _A won't exist in table _B. I created the following rule: CREATE OR REPLACE RULE view_update AS ON UPDATE TO viewtable DO INSTEAD ( UPDATE _A SET foo = false WHERE old.id = _A.id; UPDATE _B SET foo = false WHERE old.id = _B.id; ); If I do an update on table _B it returns the correct number of rows affected (1). However if I update table _A it returns (0) rows affected even though the data was changed. If I swap out the order of the updates then the same thing happens, but in reverse. How can I solve this problem so that it returns the correct number of rows affected. Thanks.

  • Postgres query optmization

    - by hdx
    Hey guys, trying to optimize this query to solve a duplicate user issue: SELECT userid, 'ismaster' AS name, 'false' AS propvalue FROM user WHERE userid NOT IN (SELECT userid FROM userprop WHERE name = 'ismaster'); The problem is that the select after the NOT IN is 120.000 records and it's taking forever. Any suggestion?

  • How can I get a distinct list of elements in a hierarchical query?

    - by RenderIn
    I have a database table, with people identified by a name, a job and a city. I have a second table that contains a hierarchical representation of every job in the company in every city. Suppose I have 3 people in the people table: [name(PK),title,city] Jim, Salesman, Houston Jane, Associate Marketer, Chicago Bill, Cashier, New York And I have thousands of job type/location combinations in the job table, a sample of which follow. You can see the hierarchical relationship since parent_title is a foreign key to title: [title,city,pay,parent_title] Salesman, Houston, $50000, CEO Cashier, Houston, $25000 CEO, USA, $1000000 Associate Marketer, Chicago, $75000 Senior Marketer, Chicago, $125000 ..... The problem I'm having is that my Person table is a composite key, so I don't know how to structure the start with part of my query so that it starts with each of the three jobs in the cities I specified. I can execute three separate queries to get what I want, but this doesn't scale well. e.g.: select * from jobs start with city = (select city from people where name = 'Bill') and title = (select title from people where name = 'Bill') connect by prior parent_title = title UNION select * from jobs start with city = (select city from people where name = 'Jim') and title = (select title from people where name = 'Jim') connect by prior parent_title = title UNION select * from jobs start with city = (select city from people where name = 'Jane') and title = (select title from people where name = 'Jane') connect by prior parent_title = title How else can I get a distinct list (or I could wrap it with a distinct if not possible) of all the jobs which are above the three people I specified?

  • DB Designer creates compound primary key

    - by Jon Winstanley
    When adding relationships to a database model in DB Designer 4, a composite primary key is being created every time. So every foreign key I add, I get an extra key added to a composite primary key. I think I must have changed a setting as I don't remember it doing this in the past. Does anyone know how to turn off this feature as I prefer to use a single surrogate primary keys in my database tables?

  • Insert a Row with a sorted DataGridView

    - by Ruben Trancoso
    My DataGridView is bound to the same BindingSource as the Insert Form, and the Name column is sorted. After insert is done, the groupBindingSource.Current is not returning the new inserted DataRowView but the last row in the sort order what makes the Update do nothing. FormGroup formGroup = new FormGroup(); formGroup .Source = groupBindingSource; formGroup .setMode(FormGroup.Mode.Insert); if (formGroup .ShowDialog() == DialogResult.OK) { DataRowView drv = (DataRowView)groupBindingSource.Current; grupoTableAdapter.Update(drv.Row); }

  • Need to fix my regex

    - by Misha Zaslavsky
    I am trying to match a string to a regex pattern, but have some problems. My string could have 3 forms: [dbo].[Start] dbo.Start Start This is my regex: "^((\[)?dbo(\])?)?(\.)?(\[)?Start(\])?$" All 3 forms returns success but there are some more options such as: [dboStart or dbo[Start I know that this is because it is optional, but how could I make dependencies when making optional, so that if one optional has value then the second optional must have a value too. Could you help me please to fix this? Thanks.

  • Why can't I create a database in an empty ASP MVC 2 project using Project->Add->New Item->SQL Server

    - by Dr Dork
    I'm diving head first into ASP MVC and am playing around with creating and manipulating a database. I did a search and found this tutorial for creating a database, however when I follow it, I get this error when trying to add a new database to my fresh, empty ASP MVC 2 project... A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) The only requirement the tutorial mentioned was SQL Server Express, but when I went to download it, it said it was already installed. I'm assuming it was part of the VS 2010 RC I installed and am running. So I don't know what else I need if I am missing something. This is all new to me, so I'm sure I'm missing something obvious here and after I'm done posting this question, I plan to do some more research into the topic of databases and how they work with ASP MVC. In the meantime, I was you could help me answer a couple high level questions... What am I missing/forgetting to do that is causing this error? Any suggestions for good resources/tutorials that focus on using databases with ASP MVC? I've done a lot of database programming in the past, so I'm familiar with the concepts of relational databases and the SQL language. I wish I could find a good resource for learning how to work with them in an ASP dev environment, as well as a good breakdown of all the related technologies used for working with them (i.e. LINQ to SQL). Thanks so much in advance for all your help! I'm going to start researching these questions right now.

  • Problem with grails web app running in production: "No such property: save for class: JsecRole"
