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:

I have a grid view with manual sorting. In some cells, the data are numeric and datetime. But due to some constrains, the data type on tables are varchar. The problem here is when I sorting those numeric data, it is treated as varchar.Eg: 1, 12, 13, 2, 23, 3, ...But I wanted the order to be: 1, 2, 3, 12, 13, 23, ...I have tried these method, but it doesnt works.

i want to convert all my database columns whose data type is char,varchar, nchar to nvarchar datatype. But the main problem is that some of my primary key, foreign key columns are also of varchar datatype. So when i try to change their datatypes to nvarchar then i receive the errors related to constraints of Primary Key, Unique Key and indexes. how to change the datatypes to nvarchar after droping the constraints and after changing all constraints will apply again. I also want that no data loss will occur.

I am using:
href='<%# Eval("Directory")+eval("Agenda")%>
to provide a link to documents held in directory so directory contains [URL] or [URL] Agenda contains
00209-FebruaryMtgMin%5E_.pdf
If I declare Directory as VarChar(nnn) where nnn is large enough to accomodate the longer field, The statement <%# Eval("Directory")+eval("Agenda")%> returns

I have an output parameter called '@packIds', that I create in ADO.Net using the code below:
SqlParameter packIdPara = new SqlParameter("@packIds", null);
packIdPara.SqlDbType = SqlDbType.VarChar;
packIdPara.Direction = ParameterDirection.Output;
sqlCmd.Parameters.Add(packIdPara);
How will I specify that the parameter '@packIds' is of max size? I cannot find any code for this.

I save dates as a string in a varchar data field named "TilDato" in a SQLServer-express table. I want to filter the records smaller than a specific date from a variable in the script. I try the following statement, but it does not seems function logically.
objCmd = new
SqlCommand("SELECT * FROM Reservering WHERE @laanedato<=TilDato",myConn2);
objCmd.Parameters.Add("@laanedato", laanedato);
objRdr = objCmd.ExecuteReader();

I need to sort this list by descending order treated as actual date. I tried converting it to date and then tried to extract the year and month out but I keep receiving conversion errors. Does anyone know how to get this in the descending order to it shows up like this:
JAN-10
NOV-09
OCT-09
SEP-09
JUL-09
NOV-08
OCT-08
SEP-08
JUN-09
MAY-09
MAR-09

This is the closest I got but it keeps sorting the list alphabetically:
select distinct periodname, Convert(varchar,periodname,112) from periodtableorder by Convert(varchar,periodname,112) desc

Not sure if this should be in SQL or .NET but as I'm doing this in asp.net I figured here..I'm trying to insert '00' into a varchar column of my database, when I do this its actually in the database as '0'... if I do '05' or '15' or '30' then its fine.

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:
[Code]....
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.

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 ??
