  • MS Access Import from Text File problems

    - by Gavin O'Brien
    I'm trying to import a text file into an access database. It's not one I've written myself but the spec for the delimited text file is set up properly and the file imports properly using the wizard. When I try to use the import functions of the app itself, the ImportError table tells "Field Truncation" for one of the fields. Any help would be appreciated.

  • PHP Doctrine: filtering data which is already loaded?

    - by ropstah
    I'm new to Doctrine and ActiveRecord. How should I filter a table after it has been loaded? (i suppose this is preferred over sending multiple queries?) Is this 'good' or 'bad'? class UserTable extends Doctrine_Table { function filterByGroup($group) { $ut = new UserTable(); foreach($this as $u) { if($u->group = $group) $ut->add($u); } return $ut; } }

  • Guilty of unsound programming

    - by TelJanini
    I was reading Robert Rossney's entry on "What's the most unsound program you've had to maintain?" found at: (What's the most unsound program you've had to maintain?) when I realized that I had inadvertently developed a near-identical application! The app consists of an HTTPListener object that grabs incoming POST requests. Based on the information in the header, I pass the body of the request to SQL Server to perform the appropriate transaction. The requests look like: <InvoiceCreate Control="389> <Invoice> <CustomerNumber>5555</CustomerNumber> <Total>300.00</Total> <RushOrder>1</RushOrder> </Invoice> </InvoiceCreate> Once it's received by the HTTPListener object, I perform the required INSERT to the Invoice table using SQL Server's built-in XML handling functionality via a stored procedure: INSERT INTO Invoice (InvoiceNumber, CustomerNumber, Total, RushOrder) SELECT @NEW_INVOICE_NUMBER, @XML.value('(InvoiceCreate/Invoice/CustomerNumber)[1]', 'varchar(10)'), @XML.value('(InvoiceCreate/Invoice/Total)[1]', 'varchar(10)'), @XML.value('(InvoiceCreate/Invoice/Total)[1]', 'varchar(10)') I then use another SELECT statement in the same stored procedure to return the value of the new Invoice Number that was inserted into the Invoices table: SELECT @NEW_INVOICE_NUMBER FOR XML PATH 'InvoiceCreateAck' I then read the generated XML using a SQL data reader object in C# and use it as the response of the HTTPListener object. My issue is, I'm noticing that Robert is indeed correct. All of my application logic exists inside the stored procedure, so I find myself having to do a lot of error-checking (i.e. validating the customer number and invoicenumber values) inside the stored procedure. I'm still a midlevel developer, and as such, am looking to improve. Given the original post, and my current architecture, what could I have done differently to improve the application? Are there any patterns or best practices that I could refer to? What approach would you have taken? I'm open to any and all criticism, as I'd like to do my part to reduce the amount of "unsound programming" in the world.

  • Retrieving Data in A NSTableView

    - by Heisennberg
    I have a three column Table View populated by two NSMutableDictionaries which share the same keys (ie key | value1 | value2 ) with dict1(key,value1) and dict2(key,value2). I want to manually enter data in the third column and create the key/value objects in dict2. But when I do that, my code picks the wrong key :S Here's the code for the delegate : - (void)tableView:(NSTableView *)aTableView setObjectValue:(id)anObject forTableColumn:(NSTableColumn *)aTableColumn row:(NSInteger)rowIndex { if ([[aTableColumn identifier] isEqualToString:@"value2"]) { [dict2 setValue:anObject forKey:[[[aTableView tableColumnWithIdentifier:@"key"] dataCellForRow:rowIndex] stringValue ]]; } } Any idea ?

  • Does UNIQ constraint mean also an index on that field(s)?

    - by Gremo
    As title, should i defined a separate index on email column (for searching purposes) or the index is "automatically" added along with UNIQ_EMAIL_USER constraint?

  • FormsAuthentication AuthCookie data type

    - by FreshCode
    Does the original data type of the username string in a call to FormsAuthentication.SetAuthCookie(...) make any difference with regards to security or code maintainability? As I understand it, the cookie is encrypted and used to identify a user on each request. I'm curious whether it should affect the design of the primary key on my Users table in my database, eg. Guid vs int or a unique username string.

  • Help with simple query - why isn't an index being used?

    - by Randy Minder
    I have the following query: SELECT MAX([LastModifiedTime]) FROM Workflow There are approximately 400M rows in the Workflow table. There is an index on the LastModifiedTime column as follows: CREATE NONCLUSTERED INDEX [IX_Workflow_LastModifiedTime] ON [dbo].[Workflow] ( [LastModifiedTime] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, IGNORE_DUP_KEY = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON, FILLFACTOR = 100) The above query takes 1.5 minutes to execute. Why wouldn't SQL Server use the above index and simply retrieve the last row in the index to get the maximum value? Thanks.

    - by chobo
    When using the repository pattern is it recommended to have one Repository class for each database table? Would I also map one service layer class to one repository class. I'm having a hard time trying to understand how much stuff one repository or service layer class should have. Thanks!

  • Declare java enum with a String array

    - by chama
    I'm trying to declare an enum type based on data that I'm retrieving from a database. I have a method that returns a string array of all the rows in the table that I want to make into an enumerated type. Is there any way to construct an enum with an array? This is what I tried, but from the way it looked in eclipse, it seemed like this just created a method by that name: public enum ConditionCodes{ Condition.getDescriptions(); } Thank you in advance!

  • Efficient SQL to count an occurrence in the latest X rows

    - by pulegium
    For example I have: create table a (i int); Assume there are 10k rows. I want to count 0's in the last 20 rows. Something like: select count(*) from (select i from a limit 20) where i = 0; Is that possible to make it more efficient? Like a single SQL statement or something? PS. DB is SQLite3 if that matters at all...

  • Is it possible to make the iPhone keyboard invisible / remove it without resigning first responder?

    - by Alex Gosselin
    I am looking for a way to show my own input view (a UITableView) to enter certain keywords in a UITextView faster than typing them, and also be able to type into this text view the normal way. My solution has a button that causes the keyboard to disappear, revealing the table view underneath it. Problem is I can't figure out how to make the keyboard go away without resigning first responder, and losing the cursor. Has anyone accomplished this before? Thanks for any help.
