How do I select a column with the latest "datetime" data type, in Visual Web Developer 2008, ASP.NET 3.5 ?
In the config data source WHERE option my options are greater than cookie, control, etc... but I would like to select where the datetime is the latest in the table.
(Select row from table where datetime is last updated....)
Thank You.
I have a list called cols with column names in it:
cols <- c('Column1','Column2','Column3')
I'd like to reproduce this command, but with a call to the list:
data.frame(Column1=rnorm(10))
Here's what happens when I try it:
> data.frame(cols[1]=rnorm(10))
Error: unexpected '=' in "data.frame(I(cols[1])="
The same thing happens if I wrap cols[1] in I() or eval().
How can I feed that item from the vector into the data.frame() command?
Hi,
I want to do this but without accesing the list "items", that is to say, to access the column perhaps with the root site or a contenttype, not depending on a list that can be created or not inside the Sharepoint app.
SPFieldChoice choice = (SPFieldChoice)items.Fields[namefield];
foreach (string choiceName in choice.Choices)
{
//etc...
}

I have a datatable. I need to fetch a certain column value based on the user input. For example, lets say the datatable has two columns CountryID and CountryName.
I need to find CountryID in the datatable based on the user input country name. I could just open a connection with DB and run the query select countryID from Country where countryName = @userinput. Is there anyway i could do this on the datatable.
Jeff Atwood asked the original question about parameterizing a SQL IN clause, but I want to do this with an integer column. If I try the code from the original post I get the following exception, which makes sense:
Conversion failed when converting the
varchar value '%|' to data type int.
Anyone try this before?

I have a conceptual model in EDM where one of the entities has a property which is essentially a big value object whose properties aren't really useful as columns in the datamodel. I'd like to apply the Serialized LOB pattern to it so that I can fit it into a 192 byte binary column.
How do I map this in the EDM v4? Is it even possible at this time?
Actually, is it possible in any ORM?

Hi there,
I am in need of reorganizing a large CSV file. The first column, which is currently a 6 digit number needs to be split up, using comma's as the field separator.
For example, I need this:
022250,10:50 AM,274,22,50
022255,11:55 AM,275,22,55
turned into this:
0,2,2,2,5,0,10:50 AM,274,22,50
0,2,2,2,5,5,11:55 AM,275,22,55
Let me know what you think!
Thanks!
How do you set a default value for a MySQL Datetime column?
In SQL Server it's getdate(), what is the equivalant for MySQL? I'm using 5.x if that is a factor.
class Radio(models.Model):
title = models.CharField(max_length=2000, blank=True, null=True)
listeners = models.IntegerField(default = 0, blank=True, null=True)
I don't want duplicate TITLE column. How do I set a unique key?
