View 6 RepliesReferencing A Column From Another Column In Datatable?
Feb 5, 2012I have a data table, i want to add a new column on that table, the data in that new column will depend in the data from another column. Now i can think of two ways to accomplish this, first is loop through the whole table and do the statements to get my new columns appropriate data. the second approach would be to give the new column an expression, then convert the table to xml (to remove the expression) then convert the xml string back to datatable.
Now, is there any other way around this? what could be the most optimized way in solving this task?

Email A Datatable In Table Format Not String?
Dec 15, 2011First I tried getting a SQL query into an array, and then mail it. Made the data incomprehendable. So someone told me to use CSS to build a table format, filling it with the array. A LOT of hard work (since I had to learn css all the way from "what is a css".

So here we go again. "What is a datatable, and how does it work"

VS 2010 - DataTable Visualizer (Date Not In Correct Format)
Nov 28, 2011I have an SQL Database which has some end dates. I have used this little statement to make sure that the dates come out of the database in the right format
Execute("Set dateformat dmy")
And I use the below statement to enter the data in to a datatable and, with the above command, when I go to look at the data in datatable visualiser the dates seem to be in the correct dd/MM/yyyy format
"SELECT CID, expdate FROM Traineecerts WHERE iscurrent = 1"
Now when i try d1 = row("expdate") the format changes to the american MM/dd/yyyy format
Please note d1 refers to a variable with the type of date. Even if I format the dates after using d1 = format(row("expdate"),"dd/MM/yyyy") they don't change unless I make d1 a string. Is this normal?

Add Column To Csv File Or Datatable?
Aug 3, 2011I have a csv file that comes in I put it into a dataset and do a little manuipulation of the appearance of how the data is presented and then I put it back out into a different csv file that our 3rd party application will except. I was importing it into SQL Server and then doing a select statement to grab the data back out in the format I required. However I'd really like to eliminate the need for the SQL Server use.
So my question is how do I add in the 1st column of a CSV file the column name "KC" with a value of "1" there will only be 1 rows worth of data, mind you it's 55 columns long but there is nothing I can do about that, it's the way it has to be.So do I do this in the DataTable or when I create the CSV file? And how do I do this?
