I have the following linq query
from o in context.Opportunities
join i in context.Interactions on o.OpportunityID equals i.OpportunityID into ints
from i in ints.DefaultIfEmpty()
orderby i.StatusID descending, o.StatusID descending
select o
Now i want to then do a distinct on the opportunities table but doing so removes my orderby. I know that you can do Distinct().OrderBy but how do i get a reference to the interactions table that was joined when I'm only selecting the opportunity entity?
When i search for some query and click on any of the results, the link is being redirected to some random sites. What could be the reason behind this? This happens with firefox
in my query i need a to count a particular column by its field name,
SELECT
C.INC_COUNT, MIN_X, MIN_Y, MAX_X, MAX_Y, B.STATE_ABBR,
B.STATE_NAME, B.LATITUDE, B.LONGITUDE, A.STATE, GEO_ID,
concat(A.LSAD_TRANS,' ' , A.NAME) DIST_NAME,
A.LSAD, GeometryType(SHAPE) GEO_TYPE, AsText(SHAPE) GEOM
from SHAPE_LAYERS A
join SHAPE_LAYER_STATE_DESC B
on ( A.state = B.state)
left outer join INC_DIST_SUMMARY_ALL C
on (C.SHAPE_GEO_ID = A. GEO_ID)
here i have to count by
B.STATE_NAME ,C.INC_COUNT
if exmple the field name nevada means i have to get all neveda value count and the C.INC_COUNT.
I want to execute query in side the db.sql file using MySQL 5.1 in windows environment. Can any one help me to this. I want to do this by runing a bat file.
The line cmd.ExecuteNonQuery();
cmd.CommandText
CREATE TRIGGER subscription_trig_0 ON subscription
AFTER INSERT AS
UPDATE user_data
SET msg_count = msg_count + 1
FROM user_data
JOIN INSERTED ON user_data.id = INSERTED.recipient;
The exception:
Incorrect syntax near the keyword 'TRIGGER'.
Then using VS 2010, connected to the very same file (a mdf file) i run the query above and i get a success message.
Currently, i am querying with this code: meta.Session.query(Label).order_by(Label.name).all()
and it returns me objects sorted by Label.name in this manner ['1','7','1a','5c']. Is there a way i can have the objects returned in the order with their Label.name sorted like this ['1','1a','5c','7']
Thanks!

In my mode I am selecting a field as

How to return dpassword as a variable to my controller

Two tables:
table_a
-------
table_a_id: (primary, int)
table_b
-------
table_a_id: (index, int, from table_a)
table_b_value: (varchar)
A one to many relationship between table_a_id and table_b_value.
Given a query like this:
SELECT DISTINCT(table_a_id) FROM table_a
JOIN table_b ON table_a.table_a_id=table_b.table_a_id
I want to order by the number of occurrences of table_a_id in table_b. I'm not really sure how to write this in MySQL.
Hi,
I am looking for HTTP parsing library for C/C++.
I have looked curl library, but it seems it is a http client library.
I am looking for a library which parses HTTP header (e.g. a way to
get the query string, get cookie, get request url, get Post Data)?
Thank you.

Is it possible to define a current user?
I found a stored procedure 'sp_mgGetConnectedUsers'. It returns a result set with the only unique field 'Address'. How could I associate an executing query with such 'Address'.
Please advice.
Note: As far as I understand, another way to get the current user is to set a unique application Id for each connection, but I don't like this way much.

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
This query generates an error because table2 doesn't exist:
Select * FROM table WHERE table2.id IS NOT NULL
Is there anything like this for check the table2 before apply the check on the id?
Select * FROM table WHERE (EXIST(table2) AND table2.id IS NOT NULL) or not EXIST(table2)
Thanks
I need a query to return this result:
+---------+-----+-------+
| ref_nid | nid | delta |
+---------+-----+-------+
| AA | 97 | 1 |
| BB | 97 | 2 |
| CC | 97 | 3 |
| DD | 98 | 1 |
| EE | 98 | 2 |
| FF | 98 | 3 |
+---------+-----+-------+
However, I do not have the delta column. I need to generate it for each nid group.
In other words, I need an auto incremented number for each group of the result.

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
