I'm using LinqToSql like this with a CheckBoxList in ASP.NET:
var teachers = from x in dc.teachers select x;
cbl.DataSource = teachers;
cbl.DataTextField = "name";
cbl.DataValueField = "teacherID";
cbl.DataBind();
I want to display both "firstname" and "name" in the DataTextField however.
I found this solution but I'm using LINQ:

How do I do this?
I'm at a loss to explain this one:
I'm getting an error "91" (Object or With block not set) on the second line below:
Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM employees")
The following also causes it:
Set rs = CurrentDb.OpenRecordset("employees")
Executing ?CurrentDb.Name alone in the immediate window causes the error as well.
Now, clearly the database is open since I'm editing the form within it, so what can cause this error here?
Hi all,
ihave created a simple project to help me get to grips with php and mysql, but have run into a minor issue, i have a working solution but would like to understand why i cannot run this code successfully this way, ill explain:
i have a function,
function fetch_all_movies(){
global $connection;
$query = 'select distinct * FROM `'.TABLE_MOVIE.'` ORDER BY movieName ASC';
$stmt = mysqli_prepare($connection,$query);
mysqli_execute($stmt);
mysqli_stmt_bind_result($stmt,$id,$name,$genre,$date,$year);
while(mysqli_stmt_fetch($stmt)){
$editUrl = "index.php?a=editMovie&movieId=".$id."";
$delUrl = "index.php?a=delMovie&movieId=".$id."";
echo "<tr><td>".$id."</td><td>".$name."</td><td>".$date."</td><td>".get_actors($id)."</td><td><a href=\"".$editUrl."\">Edit</a> | <a href=\"".$delUrl."\">Delete</a></td></tr>";
}
}
this fetches all the movies in my db, then i wish to get the count of actors for each film, so i pass in the get_actors($id) function which gets the movie id and then gives me the count of how many actors are realted to a film.
here is the function for that:
function get_actors($movieId){
global $connection;
$query = 'SELECT DISTINCT COUNT(*) FROM `'.TABLE_ACTORS.'` WHERE movieId = "'.$movieId.'"';
$result = mysqli_query($connection,$query);
$row = mysqli_fetch_array($result);
return $row[0];
}
the functions both work perfect when called separately, i just would like to understand when i pass the function inside a function i get this warning:
Warning: mysqli_fetch_array() expects
parameter 1 to be mysqli_result,
boolean given in
/Applications/MAMP/htdocs/movie_db/includes/functions.inc.php
on line 287
could anyone help me understand why?
many thanks.

Hello,
I'm developing a web application and need to page ordered results. I normaly use LIMIT/OFFSET for this purpose.
Which is the best way to page ordered results in Oracle? I've seen some samples using rownum and subqueries. Is that the way? Could you give me a sample for translating this SQL to Oracle:
SELECT fieldA,fieldB
FROM table
ORDER BY fieldA
OFFSET 5 LIMIT 14
(I'm using Oracle 10g, for what it's worth)
Thanks!
I want to be able to create a drop-down select box based on the languages my website supports. I can't seem to find a component in Wicket that does this out-of-the-box. How can I do this?
Hello, Django newbie here, I need to do a count over a certain filter in a django model. If I do it like so: my_model.objects.filter(...).count() I'm guessing it does the SQL query that retrieves all the rows and only afterwards does the count. To my knowledge it's much more efficient to do the count without retrieving those rows like so "SELECT COUNT(*) FROM ...". Is there a way to do so in django?
When i request for inbox messages in fql.query using the below query.

yyyyyyyyyy is not permitted to requested mailbox permissions from xxxxxxxxx
Say that I have a query of the form
SELECT * FROM MYTABLE WHERE MYCOL in (?)
And I want to parameterize the arguments to in.
Is there a straightforward way to do this in Java with JDBC, in a way that could work on multiple databases without modifying the SQL itself?
The closest question I've found had to do with C#, I'm wondering if there is something different for Java/JDBC.
I'm trying to set up a proxy model in django admin. It will represent a subset of the original model. The code from models.py:
class MyManager(models.Manager):
def get_query_set(self):
return super(MyManager, self).get_query_set().filter(some_column='value')
class MyModel(OrigModel):
objects = MyManager()
class Meta:
proxy = True
Now instead of filter() I need to use a complex SELECT statement with JOINS. What's the proper way to inject it wholly to the custom manager?
A process running on my machine collects data from various websites and stores it in the local mysql db. Same data is exported using SELECT INTO OUTFILE and FTPed to the shared host every few hours. My hosting provider doesn't allow LOAD DATA INFILE to be executed on the shared host? What are my other options for automated/scheduled load to MYSQL db on my shared host?
imagine 2 tables (rather stupid example, but for the sake of simplicity, here you go)
words
word_id
letters
letter
word_id
how can i select all words while selecting all letters that belong to a word and concatenating them to said word? it is important that the letters are returned in the order they appear in the table, as the letter may be mixed into other words, but the order is correct.
|word_id| |word_id|letter|
+-------+ +-------+------+
| 1| | 1| H|
| 2| | 2| B|
| 2| Y|
| 1| I|
| 2| E|
should return
|word_id|word|
+-------+----+
| 1| HI|
| 2| BYE|
any way to accomplish this in pure SQL?
I'm trying to select the id of a textArea when it's focused in
<s:TextArea id="textarea1" focusIn="selectId(event)" />
selectId(event){
event.target.id;
}
Problem is TextArea is made up of RichEditableText so target doesn't actually refer to TextArea. I've tried event.target.parent.id but still not getting there. Anyone knows how to get to the bottom of this?
Hi all,
Any idea on how to order the results of a MYSQL query by the sum of two columns rather than by a single column?
Select * FROM table ORDER BY (col1+col2) desc
I know that won't work., but I hope it conveys what I want to do fairly well.
Thanks!
Two (hopefully quick) questions about LaTeX:
How do you number select functions? I'm working in a documentclass{article}, if that matters. I want to have certain functions numbered such as
function1
function2 (1)
function3
function4 (2)
How do you make a sign to evaluate an integral? I know how to do brackets, but is it possible to only make one straight light to the right of the function with the bounds of integration? I can't figure out how to do that.
I've got a table (col1, col2, ...) with an index on (col1, col2, ...). The table has got millions of rows in it, and I want to run a query:
SELECT col1, COUNT(col2) WHERE col1 NOT IN (<couple of exclusions>) GROUP BY col1
Unfortunately, this is resulting in a full table scan of the table, which takes upwards of a minute. Is there any way of getting oracle to use the index on the columns to return the results much faster?
Hi,
In Sql Server when you select to modify a SP or UDF it loads the objects alter query in a query window. Are these queries accessible in a system table so I can store the alter statements somewhere? It looks like syscomments has some objects but not all of them.
Thanks
Hi,
i have this page.
login: [email protected] password: m
You can see two selects in the filter for which i have this rule in gente.css:
td.select label{
margin-left:12px;
}
The problem: the rule is applied but doesn't appear in the Style tab of Firebug.
Any idea?
