  • c# object initializer complexity. best practice

    - by Andrew Florko
    I was too excited when object initializer appeared in C#. MyClass a = new MyClass(); a.Field1 = Value1; a.Field2 = Value2; can be rewritten shorter: MyClass a = new MyClass { Field1 = Value1, Field2 = Value2 } Object initializer code is more obvious but when properties number come to dozen and some of the assignment deals with nullable values it's hard to debug where the "null reference error" is. Studio shows the whole object initializer as error point. Nowadays I use object initializer for straightforward assignment only for error-free properties. How do you use object initializer for complex assignment or it's a bad practice to use dozen of assigments at all? Thank you in advance!

  • Hibernate @Index on @Enumerated field doesn't work

    - by mlaverd
    I am using Hibernate to talk to my DB. I have one field that is an enumeration and it is going to be used in a slow query. So I'd like to index it. I've put the following annotations on the field: @Column(name="RIGHT_TYPE", unique=false, nullable=false, length=10) @Enumerated(EnumType.STRING) @Index(name = "ABC_INDEX") protected RightType rightType; However, I don't see any index on that field created. But I can create one manually if I wish so. Why is that? Is there any way to force Hibernate to make it happen?

  • Hibernate not using schema and catalog name in id generation with strategy increment

    - by Ben
    Hi, I am using the hibernate increment strategy to create my IDs on my entities. @GenericGenerator(name="increment-strategy", strategy="increment") @Id @GeneratedValue(generator="increment=strategy") @Column(name="HDR_ID", unique=true, nullable=false) public int getHdrId(){ return this.hdrId; } The entity has the following table annotation @Table(name = "PORDER.PUB.PO_HEADER", schema = "UVOSi", catalog = "VIRT_UVOS") Please note I have two datasources. When I try to insert an entity Hibernate creates the following SQL statement: select max(hdr_id) from PORDER.PUB.PO_HEADER which causes the following error: Group specified is ambiguous, resubmit the query by fully qualifying group name. When I create a query by hand with entityManager.createQuery() hibernate uses the fully qualified name select XXX from VIRT_UVOS.UVOSi.PORDER.PUB.PO_HEADER and that works fine. So how do I get Hibernate to use the fully qualified name in the Id autogeneration? Btw. I am using Hibernate 3.2 and Seam 2.2 running on JBoss 4.2.3 Regards Immo

  • Data model for timesheet to task and/or timesheet to project?

    - by John
    Let's say I want to make a simple project tracking system. A manager can create a project. Then he can create tasks for that project. Team members can record the hours they work for each task or for the project as a whole. Is the following design for the t_timesheet table a good idea? timesheet_id - primary key, autoincrement project_id - not null, foreign key constraint to t_project task_id - nullable, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal Or should I do something like this: timesheet_id - primary key, autoincrement task_id - not null, foreign key constraint to t_task user_id - not null, foreign key constraint to t_user hours - decimal In the second option, I intend to always have a record in t_task labelled "miscellaneous items" with a foreign key to the relevant t_project record. Then I'll be able to track all hours for a project that aren't for any particular task. Are any of the ideas above good? What would be better?

  • Ado.Net Entity produces "namespace cannot be found"

    - by Dave
    I've seen several possible solutions to this, but none have worked for me. After adding a ADO.NET Entity Data Model to my .Net Forms C# web project, I am unable to use it. Perhaps I made a mistake adding it? The name of the file added is QcFormData.edmx. In my code, perhaps I'm instantiating it incorrectly? I tried adding the line: QcFormDataContainer db = new QcFormDataContainer(); It appears in Intellisense, but when compiling I get the error : Error 13 The type or namespace name 'QcFormDataContainer' could not be found (are you missing a using directive or an assembly reference?) I've followed the suggestions that I found online that did not help: 1) made sure there is "using System.Data.Entity" 2) made sure the dll exists. 3) made sure the reference exists. 4) one post said use using System.Web.Data.Entity; but I do not see that available. What am I missing?

  • How to set up precision attribute used by @Collumn annotation ???

    - by Arthur Ronald F D Garcia
    I often use java.lang.Integer as primary key. Here you can see some piece of code @Entity private class Person { private Integer id; @Id @Column(precision=8, nullable=false) public Integer getId() { } } I need to set up its precision attribute value equal to 8. But, when exporting The schema (Oracle), it does not work as expected. AnnotationConfiguration configuration = new AnnotationConfiguration(); configuration .addAnnotatedClass(Person.class) .setProperty(Environment.DIALECT, "org.hibernate.dialect.OracleDialect") .setProperty(Environment.DRIVER, "oracle.jdbc.driver.OracleDriver"); SchemaExport schema = new SchemaExport(configuration); schema.setOutputFile("schema.sql"); schema.create(true, false); schema.sql outputs create table Person (id number(10,0) not null) Always i get 10. Is There some workaround to get 8 instead of 10 ?

  • Grails: Querying Associations causes groovy.lang.MissingMethodException

    Hi, I've got an issue with Grails where I have a test app with: class Artist { static constraints = { name() } static hasMany = [albums:Album] String name } class Album { static constraints = { name() } static hasMany = [ tracks : Track ] static belongsTo = [artist: Artist] String name } class Track { static constraints = { name() lyrics(nullable: true) } Lyrics lyrics static belongsTo = [album: Album] String name } The following query (and a more advanced, nested association query) works in the Grails Console but fails with a groovy.lang.MissingMethodException when running the app with 'run-app': def albumCriteria = tunehub.Album.createCriteria() def albumResults = albumCriteria.list { like("name", receivedAlbum) artist { like("name", receivedArtist) } // Fails here maxResults(1) } Stacktrace: groovy.lang.MissingMethodException: No signature of method: java.lang.String.call() is applicable for argument types: (tunehub.LyricsService$_getLyrics_closure1_closure2) values: [tunehub.LyricsService$_getLyrics_closure1_closure2@604106] Possible solutions: wait(), any(), wait(long), each(groovy.lang.Closure), any(groovy.lang.Closure), trim() at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy:61) at tunehub.LyricsService$_getLyrics_closure1.doCall(LyricsService.groovy) (...truncated...)

  • Conditionally set a column to its default value in Postgres

    - by Evgeny
    I've got a PostgreSQL 8.4 table with an auto-incrementing, but nullable, integer column. I want to update some column values and, if this column is NULL then set it to its default value (which would be an integer auto-generated from a sequence), but I want to return its value in either case. So I want something like this: UPDATE mytable SET incident_id = COALESCE(incident_id, DEFAULT), other = 'somethingelse' WHERE ... RETURNING incident_id Unfortunately, this doesn't work - it seems that DEFAULT is special and cannot be part of an expression. What's the best way to do this?

  • linq to sql string property from non-null column with default

    - by Barry Fandango
    I have a LINQ to SQL class "VoucherRecord" based on a simple table. One property "Note" is a string that represents an nvarchar(255) column, which is non-nullable and has a default value of empty string (''). If I instantiate a VoucherRecord the initial value of the Note property is null. If I add it using a DataContext's InsertOnSubmit method, I get a SQL error message: Cannot insert the value NULL into column 'Note', table 'foo.bar.tblVoucher'; column does not allow nulls. INSERT fails. Why isn't the database default kicking in? What sort of query could bypass the default anyway? How do I view the generated sql for this action? Thanks for your help!

  • What's the standard behaviour for an out parameter when a TryXxxx method returns false?

    - by Matt Lacey
    Assuming a method with the following signature bool TryXxxx(object something, out int toReturn) What is it acceptable for toReturn to be if TryXxxx returns false? In that it's infered that toReturn should never be used if TryXxxx fails does it matter? If toReturn was a nulable type, then it would make sense to return null. But int isn't nullable and I don't want to have to force it to be. If toReturn is always a certain value if TryXxxx fails we risk having the position where 2 values could be considered to indicate the same thing. I can see this leading to potential possible confusion if the 'default' value was returned as a valid response (when TryXxxx returns true). From an implementation point if view it looks like having toReturn be a[ny] value is easiest, but is there anything more important to consider?

  • net.sf.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type

    - by lot
    Hi! What might be reasons for running in the quoted exception upon a HQL select, when there is actually no NULL value in the respective field in the database? I've checked the database multiple times. I've manually submitted the query statement produced by hibernate (extracted from debug). Null values for the respective field are actually never returned. However, the corresponding row in the database is in fact nullable. Does hibernate care about the data base definition? I know, I could simple change the filed to a wrapper type, but we have a number of such fields in a legacy application and this only occurs upon a single query. I'm just wondering about the actual reason for getting this exception only with a single property. Any hints would be greatly appreciated.

  • Asp.net Date Binding Issue with Nulls

    - by Matthew Kruskamp
    I have a nullable date in my database. I am connecting to it with a LinqDataSource, and binding with a FormView. It allows you to place dates fine, but if you remove the date I need it to insert the null value to the db. It is instead throwing an exception. <asp:TextBox ID="TxtStartDate" runat="server" Text='<%# Bind("StartDate", "{0:MM/dd/yyyy}") %>' /> Works fine if you place a date in it, but if you delete the date out of it and save, you get System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM. How do I make it send null?

  • Error 3032 during EF 4.0 validation

    - by Mohammadreza
    Hi guys. I have a table that has a column called "rowguid" with default value of newguid(). After I delete the generated property in the Entity Framework 4.0 designer, whenever I try to build or validate the model I receive the following error message. Error 3023: Problem in mapping fragments starting at line 1460:Column People.rowguid in table People must be mapped: It has no default value and is not nullable. It's an obvious error message but the problem is that the column HAS default value. Does anyone knows what the problem is? Thanks.

  • How to do Linq aggregates when there might be an empty set?

    - by Shaul
    I have a Linq collection of Things, where Thing has an Amount (decimal) property. I'm trying to do an aggregate on this for a certain subset of Things: var total = myThings.Sum(t => t.Amount); and that works nicely. But then I added a condition that left me with no Things in the result: var total = myThings.Where(t => t.OtherProperty == 123).Sum(t => t.Amount); And instead of getting total = 0 or null, I get an error: System.InvalidOperationException: The null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type. That is really nasty, because I didn't expect that behavior. I would have expected total to be zero, maybe null - but certainly not to throw an exception! What am I doing wrong? What's the workaround/fix?

  • Sending url params and POST body to a MVC 2 Controller

    - by Luiggi
    Hi, I'm having some issues trying to make a HTTP PUT (or POST) using WebClient against a MVC 2 controller. The exception is: The parameters dictionary contains a null entry for parameter 'total' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Company(System.Guid, Int32, Int32, System.String)' The controller action is: [HttpPut] public ActionResult Company(Guid uid, int id, int total, string url) The route is: routes.MapRoute( "CompanySet", "job/active/{uid}/company/{id}", new { controller = "Job", action = "Company" } ); As you may see, what I want is to send the 'uid' and 'id' parameters via url, but the 'total' and 'url' parameters as part of the PUT or POST body. I've also tried to merge the latter parameters into a class (i.e., CompanySetMessage), doing it no longer raises an exception but I dont receive the values on the server side. Any ideas? Thank you!

  • Method of documentation for SQL Stored Procedures

    - by Chapso
    I work in a location where a single person is responsible for creating and maintaining all stored procedures for SQL servers, and is the conduit between software developers and the database. There are a lot of stored procedures in place, and with a database diagram it is simple enough 90% of the time to figure out what the stored procedure needs for arguments/returns as output. For the other 10% of the time, however, it would be helpful to have a reference. Since the DBA is a busy guy (aren't we all), it would be good to have some program which documents the stored procedures to a file so that the developers can see it without being able to access the SPs themselves. The question is, does anyone know of a good program to accomplish this? Basically what we need is something that gives the name of the SP, the argument list and the output, both with datatypes and a nullable flag.

  • How to handle null {id} on route?

    - by MattSlay
    What if a user hits my site with http://www.mysite.com/Quote/Edit rather than http://www.mysite.com/Quote/Edit/1000 In other words, they do not specify a value for {id}. If they do not, I want to display a nice "Not Found" page, since they did not give an ID. I currentl handle this by accepting a nullable int as the parameter in the Controller Action and it works fine. However, I'm curious if there a more standard MVC framework way of handling this, rather than the code I presently use (see below). Is a smoother way to handle this, or is this pretty mush the right way to do it? [HttpGet] public ActionResult Edit(int? id) { if (id == null) return View("QuoteNotFound"); int quoteId = (int)id; var viewModel = new QuoteViewModel(this.UserId); viewModel.LoadQuote(quoteId); if (viewModel.QuoteNo > 0) { return View("Create", viewModel.Quote.Entity); } else return View("QuoteNotFound"); }

  • Optional parameters for interfaces

    - by bryanjonker
    Using c# 4.0 -- building an interface and a class that implements the interface. I want to declare an optional parameter in the interface and have it be reflected in the class. So, I have the following: public interface IFoo { void Bar(int i, int j=0); } public class Foo { void Bar(int i, int j=0) { // do stuff } } This compiles, but it doesn't look right. The interface needs to have the optional parameters, because otherwise it doesn't reflect correctly in the interface method signature. Should I skip the optional parameter and just use a nullable type? Or will this work as intended with no side effects or consequences?

  • Getting .NET schema for a stored procedure result

    - by PHeiberg
    I have a couple of stored procedures in T-SQL where each stored procedure has a fixed schema for the result set. I need to map the result sets for each procedure to a POCO object and need the column name and type for each column in the result set. Is there a quick way of accessing the information? The best way I have found so far is accessing each stored procedure from .NET and writing my own extension method on a IDataReader/IDataRecord for dumping the information (column names and types) out. Example, a stored procedure executing the following query: SELECT Id, IntField, NullableIntField, VarcharField, DateField FROM SomeTable would require me to have the mapping information: Id - Guid IntField - System.Int32 NullableIntField - Nullable<System.Int32> VarcharField - String DateField - DateTime

  • Hibernate Auto-Increment not working

    I have a column in my DB that is set with Identity(1,1) and I can't get hibernate annotations to work for it. I get errors when I try to create a new record. In my entity I have the following. @GeneratedValue(strategy=GenerationType.IDENTITY, generator="native") @Column(name="SeqNo", unique=true, nullable=false) BigDecimal seqNo; But when I try to add a new record I get the following error. Cannot insert explicit value for identity column in table 'MemberSelectedOptions' when IDENTITY_INSERT is set to OFF. I don't want to set IDENTIY_INSERT to ON because I want the identity column in the db to manage the values. The SQL that is run is the following; where you can clearly see the insert. insert into dbo.MemberSelectedOptions (OptionStatusCd, EffectiveDate, TermDate, SelectionStatusDate, SysLstUpdtUserId, SysLstTrxDtm, SourceApplication, GroupId, MemberId, OptionId, SeqNo) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

  • How to achieve "merge" of two data sets with Insert SQL statemen (Oracle DBMS)t?

    - by Roman Kagan
    Hi: What would be the insert SQL statement to merge data from two tables. For example I have events_source_1 table (columns: event_type_id, event_date) and events_source_2 table (same columns) and events_target table (columns: event_type_id, past_event_date nullalbe, future_event_date nullable). Events_source_1 has past events, Events_source_2 has future events and resultant events_target would contain past and future events in the same row for same event_type_id. If there is no past_events but future_events then past_event_date won't be set and only future_event_date will be and the opposite is true too. Thanks a lot in advance for helping me resolving this problem.

Is it bug or feature? :P

  • Reusing an anonymous parameter in a prepared statement

    - by Chris Lieb
    I am customizing the insert SQL generated by hibernate and have hit an issue. When Hibernate generates the query by itself, it inserts data into the first two columns of the table, but this causes a database error since all four columns of the table are non-nullable. For the insert to be performed properly, it must insert the same data into two columns of the new record. This means that I need Hibernate to bind the same data to two different parameters in the query (prepared statement) that I am writing. Is there some SQL syntax that allows me to refer to anonymous parameters bound to a prepared statement in an order different from which they are bound? Details REF_USER_PAGE_XREF ---------------------------------------- PK FK1 | NETWORK_ID | VARCHAR2(100) PK FK1 | PAGE_PATH | VARCHAR2(1000) | USER_LAST_UPDT | VARCHAR2(100) | TMSP_LAST_UPDT | DATE insert into REF_USER_ROLE_XREF( NETWORK_ID, PAGE_PATH, TMSP_LAST_UPDT, USER_LAST_UPDT) values ( ?, /* want to insert the same data here */ ?, ?, /* and here */ (select to_char(sysdate, 'DD-MON-YY') from dual) I want to insert the same data into the first and third anonymous parameters.
