View 3 RepliesDataSource Controls :: Using Cast And Sum On VarChar Column?
Sep 29, 2010I 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:

DataSource Controls :: Replace All Varchar To Nvarchar?
Apr 1, 2010i want to convert all my database columns whose data type is char,varchar, nchar to nvarchar 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.

DataSource Controls :: Display Varchar Values In Descending Order Like MM-YY Format
Jan 25, 2010I have a column of type varchar that lists the values in this format:

OCT-09
OCT-08
NOV-09
NOV-08
MAY-09
MAR-09
JUN-09
JUL-09
JAN-10
JAN-09
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:

OCT-08
SEP-08
JUN-09
MAY-09

DataSource Controls :: Generated Update Difference Between Prod And Dev?
Mar 2, 2010I have a simple datatable with 2 fields, one a primary key which I will call PK and other which I will call COL1. I have used the dataset designer to generate update/insert/delete methods on the tableadapter. On my development system two update methods are generated wit hthe follow signatures:
Update(PK as System.String, COL1 as System.Bool, Original_PK as System.String)
Update(COL1 as System.Bool, Original_PK as System.String)
On the production system, however, the latter signature is not generated. What is more preplexing is that prior to today, production operated similar to test. Obviously somethign changed, but I have been unable to identify what.
Unfortunately the method being used now is the latter. Now I can create my own method with a similar signature, but this problem isn't unique to this datatable/tableadapter. I am very hesitent to make thsi change throughout the application, and even more so in touching the several other applications which I fear may have similar issues (though those rely less on generated udpates).
