DataSource Controls :: Split / Cast A String In Sql For Comparison?

Feb 8, 2010

comparing integer values which are actually in string (varchar(9)) right now...I'm trying to do the following in a stored procedure..

SET @MinProjectYear = SELECT ProjYear FROM P_A WHERE ID = @ID
SET @MaxProjectYear = SELECT ProjYear FROM P_A WHERE UserId = @UserID AND...
IF EXISTS(SELECT 1 FROM P_A WHERE MinProjectYear <= MaxProjectYear)
return true

The MinProjectYear and MaxProjectYear are varchar(9) values stored as "2007-2008", "2009-2010", etc.
How do I split and compare the years?? i.e. check if 2007-2008 <= 2009-2010 ??

How To Split String Adding Extra String When No Data Is There

Nov 12, 2010

I have some code that splits a session into strings by a -

My session looks something like this 123-456-789- and I split it like this

Dim MyString As String() = Session("MySession").Split("-"C)

And i've got a some code like this

Dim x as Integer

For x = 0 to MyString - 1

Response.write("Ref: " & MyString(x) & "<br>")


This writes the code like this

Ref: 123
Ref: 456

Is there a way to stop this adding in the extra one?

DataSource Controls :: LINQ Specified Cast Is Not Valid?

Jun 29, 2010

just needing a 2nd set of eyes looking at this to make sure the error isn't something else other than my LINQ code here. Here's the function class itself:


For some reason it's flagging the 2nd line in the GetJacketByPolicyID function saying the specified cast is not valid. So I'm guessing it's something I'm doing wrong. I'm sure the tblPolicy/tblPolicies class works right since I can create a new instance of a tblPolicy and set a few variables by hand and return it, so that's not it. I've also checked the datarow I'm fetching and there's no null values in the record, so that shouldn't be it either.

DataSource Controls :: Using Cast And Sum On VarChar Column?

Sep 29, 2010

I have a little problem developing a SQL Select Statement on a column that is formatted pretty badly. Firstly, the Database has already been created and filled with Data in a Test Environment, I'm not sure if the format is the same or has been updated in Production but since I'm only able to work with the Test Environment right now I'm stuck with using what I have. The Column in one Table shows a Snapshot of a clients account which is set to VarChar(50) but the actual data in the column is formatted like a money format (with a $ and decimal point so for example "$5,000.00" would be an entry in one Row).

What I'm trying to do is a create a WebService that will be used in a iPhone Application and one of the Methods needs to just give a quick display of the total value of all Clients with each specific company but I can't perform a SUM function on a VarChar column and I've tried to CAST and CONVERT the column into money, int, decimal and just about every format I can think of but I keep getting an error stating that I convert the data type varchar to which ever one I'm trying. I think it has something to do with the $ already listed in the Column, so I wanted to know what I could do to either remove the $ sign (like a Trim option) or if there is a better way of doing this that I can't think of. I know the best option would be to convert the column to the appropriate format but as I said, this was a previously designed system and I'm not sure if the Production area is the same (most likely not).

Here's what I've tried so far:

How To Get Exception Type Without String Name (ex.GetType().FullName) Comparison In Page_Error Handler

Dec 13, 2010

Is there a better way to do this than to check for Exception string?

I would rather have this catch-all error handled on the page, but for SOAP exceptions (web-service calls) I need to log the details of the actual exception that occured on the server, not the client.

The ".Detail.InnerText" property isn't in a generic exception, and can only be gotten after casting a generic exception to a SOAP exception.


I would think there is a way to get at the underlying Exception's type without using string comparison.

DataSource Controls :: Split One Data Column Into Many?

Aug 4, 2010

I've a database table contains survey questions and answers. But the problem is both 'question' and 'answer' are saved in the same column(like below).

SubmissionDate Submission
2010-02-15 14:53:59.657 ***What's your pet's name?*** Lili ***Tell us about yourself*** I'm a teacher
2010-02-15 14:53:59.657 ***What's your pet's name?*** Lucy ***Tell us about yourself*** I'm a five star cook

I'd like to use a simple datagrid to display the survey result, but I need to separate the submission column into multiple columns ('question' as column name, 'answer' as data) the number of questions or questions being asked are different for each survey so they are not fixed. Is it even possible to get something like this below in a gridview?

SubmissionDate What's your pet's name? Tell us about yourself
2010-02-15 14:53:59.657 Lili I'm a teacher
2010-02-15 14:53:59.657 Lucy I'm a five star cook
