  • SQL DROP TABLE foreign key constraint

    - by Polly Hollanger
    If I want to delete all the tables in my database like this, will it take care of the foreign key constraint? If not, how do I take care of that first? GO IF OBJECT_ID('dbo.[Course]','U') IS NOT NULL DROP TABLE dbo.[Course] GO IF OBJECT_ID('dbo.[Student]','U') IS NOT NULL DROP TABLE dbo.[Student]

  • How should I organize complex SQL views in Rails?

    - by Benjamin Oakes
    I manage a research database with Ruby on Rails. The data that is entered is primarily used by scientists who prefer to have all the relevant information for a study in one single massive table for use in their statistics software of choice. I'm currently presenting it as CSV, as it's very straightforward to do and compatible with the tools people want to use. I've written many views (the SQL kind, not the Rails HTML/ERB kind) to make the output they expect a reality. Some of these views are quite large and have a fair amount of complexity behind them. I wrote them in SQL because there are many calculations and comparisons that are more easily done with SQL. They're currently loaded into the database straight from a file named views.sql. To get the requested data, I do a select * from my_view;. The views.sql file is getting quite large. Part of the problem is that we're still figuring out what the data we collect means, so there's a lot of changes being made to the views all the time -- and a ton of them are being created. Many of them need to be repeatable. I've recently run into issues organizing and testing these views. Rails works great for user interface stuff and business logic, but I'm not aware of much existing structure for handling the reporting we require. Some options I've thought of: Should I move them into the most relevant models somehow? Several of the views interact with each other, which makes this situation more complex than just doing a single find_by_sql, so I don't know if they should only be part of the model. Perhaps they should be treated as a "view" in the MVC sense? (That is, they could be moved into app/views/ and live alongside the HTML, perhaps as files named something like my_view.csv.sql which return CSV.) How would you deal with a complex reporting problem like this?

  • c# linq to sql join problem

    - by b0x0rz
    i am trying to do using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses.EMailAddress == "[email protected]" select u; return users.Count(); } however, when i get to: using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses. i do not get offered the EMailAddress name, but rather some neutral default-looking list of options in intelisense. what am i doing wrong? table Users ID bigint NameTitle nvarchar(64) NameFirst nvarchar(64) NameMiddle nvarchar(64) NameLast nvarchar(64) NameSuffix nvarchar(64) Status bigint IsActive bit table UserEMailAddresses ID bigint UserID bigint EMailAddress nvarchar(256) IsPrimary bit IsActive bit obviously, 1 user can have many addresses and so Users.ID and UserEMailAddresses.UserID have a relationship between them: 1 to MANY.

  • Clean up State field with T-SQL?

    - by Pselus
    The State field in our database is a mess. There was no validation when it was filled so we have everything from two letter abbreviations to full state names to misspelled state names to "test" and "xxxx", etc. I am not going to try to handle everything, but for sure I want to fix the correct state names to abbreviations. I have a list of valid state names and abbreviations, but I don't know how I can do this: UPDATE Table SET State = ('AR','AK') WHERE (SELECT * FROM Table WHERE State IN ('Arkansas','Alaska')) Basically, can I update a field to be something from a list by the location it is in another list?

  • Dynamic Like Statement in SQL

    - by Peter McElhinney
    Hey there! I've been racking my brain on how to do this for a while, and i know that some genius on this site will have the answer. Basically i'm trying to do this: SELECT column FROM table WHERE [table][column] LIKE string1 OR [table][column] LIKE string2 OR [table][column] LIKE string3... for a list of search strings stored in a column of a table. Obviously I can't do a like statement for each string by hand because i want the table to be dynamic. Any suggestions would be great. :D EDIT: I'm using MSSQL :(

  • SQL: how to get the left 3 numbers from an int

    - by dmr
    I want to retrieve the left 3 numbers from an integer to be stored in a table. For example, if the int is 1234567, I want to retrieve 123. I want the second number (123) to also be an int; I don't want to convert anything to a string. (And yes, really I should be working with strings. But I don't have control over that aspect of the issue.) Thank you!

  • How to implement multi relationship in SQL Server?

    - by Ethan
    I’m trying to design a database to use with ASP.net MVC application. Here is the scenario: There are three entities and users can post their comments for each of these different entities. I just wonder how just put one table for Comments and link all other entities to it. Obviously, Comments table needs 3 references (foreign key) to those tables but as you know these foreign keys can’t be null and just one of them can be filled for each row. Is there any better way than implementing three different tables for each entity’s comments?

  • SQL Server: Mitigating schema changes/upgrades

    - by bradhe
    I haven't spent a ton of time researching this yet, mostly looking for best practices on upgrading/changing DB schemas. We're actively developing a new product and as such we often have additions or changes to our DB schema. We also have many copies of the DB -- one for the test environment, one for the prod environment, dev environments, you name it. We don't really want to have to blow away test data every time we want to make a change to the DB. Are there good ways of automating this or handling this? None of us have really ever had to deal with this so...

  • Comparing Page.User.Identity.Name to value in sql Table

    - by Peggy Fusselman
    First, I am SO sorry if the answer is out there. I've looked and looked and feel this is such a simple thing that it should be obvious. I'm wanting to make sure only the person who added an event can modify it. Simple! I already have a datasource that has event_added_by as a data point. It is populating a FormView. SelectCommand="SELECT * FROM [tbl_events] WHERE ([event_ID] = @event_ID)" And I have Page.User.Identity.Name. How do I compare the two? I can't pull the value from the label in the FormView so I need to find another way. if (!IsPostBack) { string uname = Page.User.Identity.Name; string owner = ""// this is where I need to grab the value from dsEvents; if (uname != owner) { //Send them somewhere saying they're not allowed to be here } } TIA for any help!
