I'm on training in a company and i'm making a web application with an SQL server database..Now I created everything but i need to know how to program a search function..t's the point that when I search to a computer it'll put all the pc's with the matching word into the dropdownlist..Like when you search for "A" I get all the pc's wich has an 'A' in their name, I made everything, in the query builder I made a parameter with the textbox but i need not EXACT the value I typed but verything wich has it in it.
I am currently working on this situation that I could not find any other resources online to help me Everything is working fine through VS2008 debug mode, or run without debugging ( database connectivity and everything works)but however when i copy the whole project and set up the IIS, everything work except for database connectivity. I could not seems to read from the database which currently I am using a attached .mdf file
the error shown is as below :
Server Error in '/' Application.
Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

but however when i run on VS 2008, I am able to read the data from the database successfully,
The drop down list is used to determine what search criteria will be used to find an invoice. I tried to set the Select method in the switch statement. I don't understand how to set the Select Method and the select parameters programmatically though . I tried a few different ways but can't make the compiler happy. My ODS is in scope in the code behind. I'm not able to access it's properties though. The BAL resides in a separate project that is a ClassLibrary. I also have a using statement for the ClassLibrary project in the code behind.
I will declarate a attribute, but it gives me an error
This query works fine and returns 1 record from type int:
SELECT TOP 1 DataObjectVersionID FROM tblDataObjectVersionPropertyValueText WHERE PropValue like CAST('00010281' AS ntext) ORDER BY DataObjectVersionID DESC
And when I will declarate a attribute/parameter it gives me an error:
DECLARE @dataObjectVersionId INT SET @dataObjectVersionId = SELECT TOP 1 DataObjectVersionID FROM tblDataObjectVersionPropertyValueText WHERE PropValue like CAST('00010281' AS ntext) ORDER BY DataObjectVersionID DESC
Error message:
Msg 156, Level 15, State 1, Line 2 Incorrect syntax near the keyword 'SELECT'.
I have a VS2010 project that I want to move back and forth between an x86 and an x64 machine. On the x86 machine, several assemblies are located in Program Files, and the path of the assemblies are shown as c:Program Files...... When I move this project to the x64 machine, the same assemblies are located in C:Program Files (x86).... Is there a way that I can confugure VS2010 so I don't have to manually change the path when I move the project from one machine to another?
I have a table with number fields, one of which is location. What I want is a select command which put all records for the selected location first then adds all the others on the end in what ever order they occur.

How would you handle an INSERT that gets some values from another table using SELECT, where you wanted some values to come from the source table record and other values to come from a different parameter source like a session value? Is this possible?
I have a SQL select statement with inner joins to get a total number of records for the statement. I have tried using count with group by's but it just counts one for each record instead of giving me the total number of records for the query. Here is the query:
There may be a lot of data in the Blogs table. What if all I wanted was say BlogID, BlogTitle and BlogAuthor and nothing else, is there a way to do this in an effort to make the sql more efficent?
Along the same lines in my DataContext (.dbml) file I added some associations between some of my tables. This makes coding nice when I do a linq statement that will join those tables automatically for me but my concern is does it do that everytime, thus making all my linq quieries inefficient?
I have a query that looks like this attached to a sqldatasource :
SELECT [fldBaseline] FROM [BI_PATHS_Target_Baseline] WHERE fldBranch = @fldBranch and fldyear=@fldyear and fldcategory = @cat
and i want to make a LABEL to read that fldbaseline value and i tried this :
[Code]....
btw the @fldbranch is pulling from a dropdownlist and so it the @year but the @cat is just defined always as 'LEAN' But im not sure what to put inside the select() part. i know you have to put atasourceselectarguments.empty if no parameters, but what would I do here since their are 3?
My query was SELECT ID FROM TBLCARS WHERE (ID IN (1, 5, 3, 6))
this will usualy produces the result 1,3,5,6 order.But i want the result in the specefied order of ids.ie:1,5,3,6;ie;first get the row with id 1,then with id 5,then id 3,and last 6.
I need to create a SELECT statement for a table that excluded the TOP 10 records.
"SELECT TOP 10 field1,field2,field3 FROM AppData ORDER BY field1 DESC" returns the first 10 records from the table but I need to retrieve only from the 21st record onwards.
I simply don't know how to do it because I'm not that strong with SQL. I searched the forum for some answers but can't find a solution that I can understand.
I have a problem with my SQL statement that only needs to show future dates in the Gridview.I use vb, vs 2005.I want a DateTime Field(TEndDate) to act as a control field in that only future dates (WHERE TEndDate >= Now.Date.Date) should be returned.It asks for my paramaterized value when I'm building the query.I'm unsure about the source I should select for the query.(The options are: None/Control/Cookie/Form/Profile/Querystring/Session)I'm losing my mind with this!Here is my code:
I am reading an integer named "CostIndex" from a database table.I need to cast it to an integer and then pad the result withleading zeroes.So if CostIndex is only one digit then I need to pad it with 3 leading blanks: 0007I know how to find the length, using LEN,but I don't know what to do beyond that? select CAST(CostIndex AS VARCHAR(4)) from TableRoot
