I am developing an application which may be hosted on a microsoft sql server, or on Azure SQL, depending upon the end user's wishes.
My whole system works fine with the exception of some WCF functions which determine the last modification time of tables using the following technique:
SELECT OBJECT_NAME(OBJECT_ID) as tableName,
last_user_update as lastUpdate
FROM mydb.sys.dm_db_index_usage_stats
This query fails in Azure. Is there any analogous way to get table last modification dates from Azure's sql?
I'm struggling getting my head around the Django's ORM. What I want to do is get a list of distinct values within a field on my table .... the equivalent of one of the following:
SELECT DISTINCT myfieldname FROM mytable
(or alternatively)
SELECT myfieldname FROM mytable GROUP BY myfieldname
I'd at least like to do it the Django way before resorting to raw sql.

hi,
I need to extract data from my SQL Server database into multiple text files.
I have a table with 4 columns: UserID, UserName, Tag, Score.
I need to create a text file for each Tag (so basically I need to group by Tag and order by score).
Before to start I would like to know what's the fastest way to create several text files:
File titles = TAG field
each line = userID
My table looks like this with duplicates in col1
col1, col2, col3, col4
1, 1, 0, a
1, 2, 1, a
1, 3, 1, a
2, 4, 1, b
3, 5, 0, c
I want to select distinct col1 with max (col3) and min(col2);
so result set will be:
col1, col2, col3, col4
1, 2, 1, a
2, 4, 1, b
3, 5, 0, c

I am trying to get the value of a cell in a table view but it won't let me. If someone could help that would be great.
int numberOfChecks = -1;

UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:numberOfChecks];
NSString *cellTitle = cell.textLabel.text;
}
I am having a hard time understanding how to change the width of columns when creating a table view.
I know you can set the width in pixels of a column but that is not what I want to do.
Say, for instance, I have 2 columns and want each column to take up half the screen. How do I do this without explicitly setting the pixels, so that my code can work on multiple screen sizes?
can any one explain hiow this query works..It's for getting the Nth largest elemet from a table.here it's 4 th largest
SELECT a.ID
FROM tblitem a
WHERE (4) = (select count(*)
from tblItem b
where b.id < a.id)
Thanks in advance
