  • Null Value Statement

    - by Sam
    Hi All, I have created a table called table1 and it has 4 columns named Name,ID,Description and Date. I have created them like Name varchar(50) null, ID int null,Description varchar(50) null, Date datetime null I have inserted a record into the table1 having ID and Description values. So Now my table1 looks like this: Name ID Description Date Null 1 First Null One of them asked me to modify the table such a way that The columns Name and Date should have Null values instead of Text Null. I don't know what is the difference between those I mean can anyone explain me the difference between these select statements: SELECT * FROM TABLE1 WHERE NAME IS NULL SELECT * FROM TABLE1 WHERE NAME = 'NULL' SELECT * FROM TABLE1 WHERE NAME = ' ' Can anyone explain me?

  • SQL 2000 - Returning from a Stored Procedure

    - by user70192
    Hello, I'm writing a stored procedure. This procedure has a case where if it is met, I want to stop executing the procedure and return -1. How do I do this? Currently, I'm trying the following: IF @result <> 1 BEGIN SELECT -1 END However, SELECT is not a typical "return". As you can imagine I spend most of my time in code which is why i'm looking for something like a "return". Thank you,

  • Linq To SQL: Retain list order when using .Contains

    - by rockinthesixstring
    I'm using Lucene.net to build a MyListOfIds As List(Of Integer) which I then pass on to my Linq service. I then search the database as follows Return _EventRepository.Read().Where(Function(e) MyListOfIds.Contains(e.ID)).ToList Now I know that Lucene is already ordering MyListOfIds based on the weight it gave each term. What sucks is that Linq is losing that order in it's SQL search. My Question: How can I retain that sort order when building my Lambda expression? I tried using LINQPad to see how the query is being built, but because I had to declare a variable LINQPad didn't show me the resultant SQL :-( Here's what I tried in LINQPad Dim i As New List(Of Integer) i.Add(1) i.Add(100) i.Add(15) i.Add(3) i.Add(123) Dim r = (From e In Events Where i.Contains(e.ID) Select e) note: my example is in VB.NET, but I don't mind if responses are in C#

  • Most efficent way to limit rows returns from union query- TSQL

    - by stephen776
    Hey guys...I have a simple stored proc with two queries joined with a union select name as 'result' from product where... union select productNum as 'result' from product where... I want to limit this to the TOP 10 results... if i put TOP 10 in each seperate query I get 20 results total. What is the most efficient way to limit total results to 10? I dont want to do TOP 5 in each because I may end up in a situation where I have something like 7 "names" and 3 "productsNumbers"

How can I do this? Any information is appreciated. Thanks. class Order { int OrderId; List<Product> Products; } class Product { string name; int SequenceNumber; }

  • Duplicate a database record with linq

    - by holz
    Is there a way to duplicate a db record with linq to sql in c#? Id [int] IDENTITY(1,1) NOT NULL PRIMARY KEY, [Foo] [nvarchar](255) NOT NULL, [Bar] [numeric](28,12) NOT NULL, ... Given the table above, I would like to duplicate a record (but give it a different id), in a way that new fields added to the DB and the Linq dbml file at a later date will still get duplicated with out having to change that code that duplicates the record. ie I don't want to write newRecord.Foo = currentRecord.Foo; for all of the fields on the table.

  • SQL left join with multiple rows into one row

    - by beardedd
    Basically, I have two tables, Table A contains the actual items that I care to get out, and Table B is used for language translations. So, for example, Table A contains the actual content. Anytime text is used within the table, instead of storing actual varchar values, ids are stored that relate back to text stored in Table B. This allows me to by adding a languageID column to Table B, have multiple translations for the same row in the database. Example: Table A Title (int) Description (int) Other Data.... Table B TextID (int) - This is the column whose value is stored in other tables LanguageID (int) Text (varchar) My question is more a call for suggestions on how to best handle this. Ideally I want a query that I can use to select from the table, and get the text as opposed to the ids of the text out of the table. Currently when I have two text items in the table this is what I do: SELECT C.ID, C.Title, D.Text AS Description FROM (SELECT A.ID, A.Description, B.Text AS Title FROM TableA A, TranslationsTable B WHERE A.Title = B.TextID AND B.LanguaugeID = 1) C LEFT JOIN TranslationsTable D ON C.Description = D.TextID AND D.LanguaugeID = 1 This query gives me the row from Table A I am looking for (using where statements in the inner select statement) with the actual text based on the language ID used instead of the text ids. This works fine when I am only using one or two text items that need to be translated, but adding a third item or more, it starts to get really messy - essentially another left join on top of the example. Any suggestions on a better query, or at least a good way to handle 3 or more text items in a single row?

  • Multiple fields from LINQ to Text Box

    - by Chuki2
    how can I pass value from selected field (LINQ) to textbox in winforms? If single fields, I just do like this var result = from row in dtValueBranch.AsEnumerable() where row.Field<int>("branchID") == idBranch select row.Field<string>("branchName"); StringBuilder sb = new StringBuilder(); foreach (string s in result) { sb.Append(s + Environment.NewLine); } tbBranch.Text = sb.ToString(); So this is the code LINQ to many fields var result = from row in dtValueBranch.AsEnumerable() where row.Field<int>("branchID") == idBranch select new { BranchName = row["branchName"].ToString(), branchTel = row["branchTel1"].ToString(), // And many more fields }; How can I to implement each fields to each textbox?

  • SQL Query Theory Question...

    - by Keng
    I have a large historical transaction table (15-20 million rows MANY columns) and a table with one row one column. The table with one row contains a date (last processing date) which will be used to pull the data in the trasaction table ('process_date').
