View 2 RepliesWill CLOB Data Be Truncated When Displayed In A Select Query? If So, How Can It Be Displayed
Jul 1, 2010I've got a Varchar2 field in my table which I want to convert to a CLOB. I am unsure whether the data would get truncated when selected. If so, what is the limit and does it depend on the database settings?
In my TOAD or SQLPLUS window it gets truncated but this may just be the environment settings. I'm not sure whether it would get truncated in my actual application (I can test this, but up to what size should I test?)
If it does get truncated, what's the best way to display the whole CLOB? There are other fields in my SELECT query, so I think I can't just loop through multiple rows. Is there any way out?

Databases :: Detecting Nulls In Output Parameter Using ODP?
May 17, 2010I'm converting my application from using System.Data.OracleClient to Oracle.DataAccess.Client and I've noticed some weird behavior.
I am calling a stored procedure that sets an output parameter value. Under some circumstances, a null value gets assigned to this value and I need to detect it.
Here's how I'm declaring it using ODP.net:
cmd.Parameters.Add("p_status", OracleDbType.VarChar2, 200, DBNull.Value, ParameterDirection.Output)
The old Microsoft driver for Oracle would read the value as an empty string. However, ODP is returning a value {null} (per Visual Studio's debugger), which is not equivalent to null, DBNull.Value, nor an empty string. As a result, the code doesn't branch correctly now.
C# - Output A GridView To Excel Outside Of Page?
Feb 24, 2011I want to have a helper class that can serve requests from multiple pages to output contents of any gridview to excel. But if I pass in the GridView it throws an error that it must be inside "form runat='server'" tags, which makes sense. However is there anyway to do this in a seperate class that is not directly connected to any particular page?

MVC :: Output Caching And Query Dependency?
Sep 21, 2010I plan to use output cache for my page and also specify sql dependencyi succeded in doing it the following way
[Code]....
Suppose if i want to implement a dependency on the sql query , i create an sqlcache dependency object and specify the sql command to it.Set the notifications .But how do i add this sqldependency to the output cache?For example: if i need to add a file dependency, i give something like Response.AddFileDependency ("filepath"); is there any similiar command available for sqldependency as well? I'm confused about this because, most of the examples i've looked into, does a cache.insert , which defeats my purpose as it's object caching and not output caching. In a nutshell, is it possible to attach a sqlcachedependency to o/p cache inside the controller action

Web Forms :: Web Parts And Anonymous User And Authenticated User Is Displayed Differently?
Mar 21, 2011the Web Part for anonymous user and authenticated user is displayed differently. I faced this problem twise. First time when used Silverlight control in the Web Part and second time when used devexpress control in the Web Part. In both cases problem was with displaying for anonymous user. Silverlight control didn't display. Devexpress control lost it's styles. Both controls had properties that pointed to files. Silverlight control property pointed to the XAP file, and Devexpress control property pointed to the CSS file. It seems to me, that for anonymous user the Web Part cannot find this path or doesn't allow to link to other files.

Feb 16, 2012I am trying to clean up some application work. I have this query application that creates a report that is displayed in a gridview in a new window. If the records have further information the gridview displays a field containing a URL (which is generated in SQL) to open an edit form allowing the user to view and edit the selected record. The URL looks something like this:

View 1 RepliesSQL Server :: Convert Date Type In Query Output ?
Oct 20, 2010In my database when anyone registers - By default the registration time is saved as UTC universal time zone.
But i want to display everything on the website in (GMT-05:00) Eastern Time (US & Canada)
I am using this SQL QUERY to display registration date:
SELECT TOP (5) Username, CustomerID, RegistrationDate = CONVERT(VARCHAR(12),RegistrationDate,107) FROM Customer ORDER BY RegistrationDate DESC
And, i am displaying it like this:
<asp:Label ID="nameLabeldate" runat="server" Text='<%# Eval("RegistrationDate") %>' />
The problem is the output is getting displayed as : 10/20/2010 1:36:01 PM
I know RegistrationDate is datetime stamp that's why i am getting output in this format.
But i want to display RegistrationDate as: Oct 20, 2010 at 1:36pm -> according to (GMT-05:00) Eastern Time (US & Canada) ORDER BY RegistrationDate in Desc (top most will be last registered user)
Web Forms :: How To Export An Image File To Excel Using The Output HTML Method
Dec 31, 2010I'm trying to export data from an asp.net page to an Excel file and I'm basically just outputting HTML to the XLS file and let Excel interprets it, by using this type of coding:
[Code]....
Although this is doing fine for exporting raw text, I now have to export to the same Excel file an image. However, the same kind of method I'm using right now only seems to insert a "linked" image, I mean, the image appears in the file, however, the user viewing the file has to be online since it's a direct link to the file in the server. I would like to able to "embeded" the image in the file, just like how it's made when you insert manually an image using Excel.
However, after some online research I can't seem to find any solution for this.
I can't use Microsoft.Office.Interop.Excel library, and a third party software isn't advisable also, that's what made me try out the HTML output solution, which worked ok for the text. But now, for inserting an image, what can I do? Is it possible to achieve what I pretend?
SQL Server :: Sql Query - Vertical Records For Particular Part_no Should Be Horizontally Displayed In A Single Row
Nov 25, 2010I have a sql table like this-
Sno part_no desc supplier currency price
1 10245890 abc abc electricals INR 0.320000
2 10245890 abc abc electricals INR 0.560000
3 10245890 abc def electricals USD 0.780000
4 10345780 def xyz electricals YEN 0.345678
5 10345780 def pqr electricals USD 0.000678
Now whenever user input the part_no output should be displayed like this- foe eg.. if user input 10245890, the ouput should be like this-
Sno part_no supplier1 currency1 price1 supplier2 currency2 price2 supplier3 currency3 price3
Means vertical records for particular part_no should be horizontally displayed in a single row. How can i write a sql query to achieve this?
