Hi
I have developed application using HTML 5 Localstorage.
How can I create a TABLE and populate 10000+ rows before initializing my
HTML 5 enabled application.
Please suggest a pattern.
Im using c# .net windows form application. i have a SQL database with 5 tables. i need to populate a combobox with these table names. only names should be displayed.
I have a question about using subqueries in an Update statement. My example:
UPDATE TRIPS
SET locations = city + ', ' FROM (select Distinct city
from poi
where poi.trip_guid = trips.guid)
Is it possible to refer to main table value (trips.guid) in subqueries?
When i try to use trips.guid I get the error:
"The multi-part identifier "trips.guid" could not be bound."
I have asp:Table with number of asp:Label inside asp:FormView, it represents short stats info.
I need to set Label.CssClass to "red" if it's text isn't "0".
Currently I do this on FormView.DataBound event. But think that it's better to use JavaScript and probably jQuery. How can I do that?
hi,
I need to compare the content of 2 tables, more exactly 2 columns (1 column per table) in Matlab to see, for each element of the firsts column, there is an equal element in the second column.
Should I use a for loop or is there any MATLAB function doing this ?
thanks
Using hibernate with annotations, i want a one-many relationship to be sorted by the 'created' field on the 'many' table.
So far i've got this, which always ends up in a random order:
// The notes
@OneToMany
@JoinColumn(name="task_id")
Set<TaskNote> notes;
public Set<TaskNote> getNotes() {return notes;}
public void setNotes(Set<TaskNote> notes) {this.notes = notes;}
I need to find the amount of updated rows
UPDATE Table SET value=2 WHERE value2=1
declare @aaa int
set @aaa = @@ROWCOUNT
It doesn't work. How can I do that?

Hi
I have set the background of my UITable with a custom image.
self.tableView.backgroundColor = [UIColor clearColor];
self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"background.png"]];
The problem im having is the background image is scrolling and doesn't look good at the top and bottom of the screen where you see the image being joined.
Is there a way to fix the position of the background image and just have the table scroll over the top of it?

class books(models.Model):
title = models.CharField...
ISBN = models.Integer...

How would I write the raw SQL in my database so that this column works?
SHOW TABLE STATUS LIKE 'foo' returns Data_length - size of all data, and Index_length - size of all indexes. What's the best way to get per-column and per-index breakdown?

Hello,
Recently I needed to generate a huge HTML page containing a report with several thousand row table. And, obviously, I did not want to build the whole HTML (or the underlying tree) in memory. As result, I built the page with the old good string interpolation, but I do not like the solution.
Thus, I wonder whether there are Python templating engines that can yield resulting page content by parts.
I know in asp.net 1.0 the grid display controls would pull all the data in, and then provide paging but the paging was done in memory.
Are there any smarter controls that provide paging where they only pull the data relevent to current page being displayed?
ie. select 10 rows for the current page, instead of doing a select of ALL the rows in the table.
I have a table with products, their amount and their price. I need to select all entries where the average price per article is between a range.
My query so far:
SELECT productid,AVG(SUM(price)/SUM(amount)) AS avg FROM stock WHERE avg=$from AND avg<=$to GROUP BY productid
If do this, it tells me avg doesnt exist.
Also i obviously need to group by because the sum and average need to be per wine
I have a MySQL query which gets including some vars like that:
messages TABLE receiver cols
user1 rows : 1,3,5
user2 rows : 2,3
user3 rows : 1,4
I want to get rows which includes '3' value. So I will get 'user1' and 'user2'.
I tried that but naturally it doesn't work.
mysql_query("SELECT * FROM messages WHERE receiver='3'");
How can I do this?
Hi, I've recently done a migration from a really old version of some application to the current version and i faced some problems while migrating databases.
I need a query that could help me to compare columns in two tables. I mean not the data in rows, I need to compare the columns itself to figure out, what changes in table structure I've missed.
I am doing a query with three tables, the problem was one table has many occurrences of id of another.
sample data:
users: id
answers:
id:1
user_answer :1
id:1
user_answer :2
id:1
user_answer :3
Questions:
id:1
answers :answer description
id:2

id:3

According to this: http://code.google.com/appengine/docs/whatisgoogleappengine.html
it seems that GAE only uses Datastore to store data, which is equivalent with Table service on Windows Azure Platform.
Does anyone know that which RDBMS it uses? or such thing exists or not?
what is the difference between the symfony "myUser" and doctrine model "User"?
where should i put the methods for an user?
eg. $user-createThread(), $user-deleteThread() and so on
should $user be an instance of the doctrine model User (cause i have a table called User) or the myUser that extends sfBasicSecurityUser?
thanks!
