Hi all,
it may be wrong place to ask this question, but i hope u all programmer must have the interesting naming convention of variables. i have seen many places that some variable names are very good n effective like
common variable names
$link

$query
$stmt
$sql
$qry
$output
$result
$list
so please suggest me some good names for variable , bcoz all time i have to write
$x, $y etc.. if i want to save something instantly on page...that are even not relevant, so please suggest me good variable names

I have in my model:
def presenter
@presenter ||= ProfilePresenter.new(self)
@presenter
end
The ProfilePresenter is a class that has methods like, get_link(), get_img_url(size), get_sex(), get_relationship_status() and other methods that have not to do with the model, not even with the controller but is used multiple times in the view.
So now i use them by doing this:
Profile.presenter.get_link
# or
Profile.presenter.get_img_url('thumb') # returns the path of the image. is not used to make a db query
consider a tale is as follows,
EmployeeId | Name | Phone_Number
Now, i insert 10 records... When i query them back, select * from myTable they are not selected in the order i inserted. I can obviously keep an autoincrement index and ORDER BY index. But i dont want to alter the table. How can i do this without altering the table?
I'm in a situation now were I need to convert a datarow I've fetched from a query into a new instance of an object. I can do the obvious looping through columns and 'manually' assign these to properties of the object - or I can look into reflection such as this: http://www.codeproject.com/Articles/11914/Using-Reflection-to-convert-DataRows-to-objects-or
What would I base the decision on? Just scalability??

Hi,
I have just started to learn about the pros of foreign keys in database design (mySQL / innoDB) and I wonder if there's any way to temporarily bypass the foreign key when doing a specific delete query, to just delete in the parent table, and not from the linked child tables.
Thanks
I'm learning how to use SQL Server Management Studio and can't figure out how to insert a new row into a table.
Table Structure:
ID,
Field1,
Field2
Query:
INSERT INTO Table (Field1,Field2) VALUES(1,2)
Error:
Major Error 0x80040E14, Minor Error 25503
I'm probably missing something very noobie like. Any help would be appreciated.
I am trying to output a long XML result from SMSS.
When I right click on the results and 'save results as...', I can only get a 2mb file?
I have changed the settings in SMSS via Tools - Options - Query Results - SQL Server - Results to Grid, for XML data to be unlimited.
Forever, it still seems to be truncating my XML results?
So, how can I bypass this problem and output my XML result to a file?
Thanks

Say I have a dataframe df with two or more columns, is there an easy way to use unique() or other R function to create a subset of unique combinations of two or more columns?
I know I can use sqldf() and write an easy "SELECT DISTINCT var1, var2, ... varN" query, but I am looking for an R way of doing this.
It occurred to me to try ftable coerced to a dataframe and use the field names, but I also get the cross tabulations of combinations that don't exist in the dataset:
uniques <-
as.data.frame(ftable(df$var1,
df$var2))
Hello,
I have a table containing last_updated_1 and last_updated_2 columns, used respectively for text and images update time on a post.
I wish I could get a result set of 10 rows based on all time last updated records contained in the 2 columns, ex. row 1 = last_updated_1 record, row 2 = last_updated_2 record, row 3 = last_updated_1 record, etc.
How could I compare inside a MySQL query the both columns values, to get unique & mixed result set ?
Thank you in advance for your help

Hello,
I'm trying to copy the contents of one table into another in Postgres, however it appears some rows aren't being copied correctly:
ActiveRecord::StatementInvalid:
PGError: ERROR: column "email_date" is
of type timestamp without time zone
but expression is of type character
varying HINT: You will need to rewrite
or cast the expression.
Is there any way I can have it automatically skip (or ignore) invalid rows?
Here's the query I'm using:

This simple query throws the "Ambiguous column name TaskID" error on one db-server only. This is ridiculous. We tested this with the same database structure on different servers and different versions of ms sql (2005/2008), and it's only THIS particular client's server that throws the error. I'm actually frustrated.
SELECT Tasks.TaskID
FROM Tasks
INNER JOIN TaskHelpers ON TaskHelpers.TaskID = Tasks.TaskID
order by TaskID
Yes, I know I can put "Tasks.TaskID" into the order by clause, but for some reasons I can't.
I have the below query
Select
case upper(device_model)
when 'IPHONE' then 'iOS - iPhone'
when 'IPAD' then 'iOS - iPad'
when 'IPOD TOUCH' then 'iOS - iPod Touch'
Else 'Android'
End As Device_Model,
count(create_dtime) as Installs_Oct17_Oct30
From Player
Where Create_Dtime >= To_Date('2012-Oct-17','yyyy-mon-dd')
And Create_Dtime <= To_Date('2012-Oct-30','yyyy-mon-dd')
Group By Device_Model
Order By Device_Model
This spits out multiple rows of results that read "Android"....I would like there to be only 4 results rows, one for each case....so it comes out like this:
Device_Model Installs_Oct17_Oct30
Android 987
iOS - iPad 12003
iOS - iPhone 8563
iOS- iPod Touch 3482
