HI
One of my requirement is to have prefix on all the tables of the django based project (Because db is hosted on shared server). I have used db_table Meta option to set the prefix for the tables which I have created.
Now my query is how do I set the prefix for tables provided by django.contrib.
Instead of auth_group django should create prefix_auth_group.... How do I do that?
Thank you very much...
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.
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 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
I have a mysq 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?
The answer in this post http://stackoverflow.com/questions/2119680/use-jquery-to-check-if-a-url-on-another-domain-is-404-or-not shows how to use YQL in Jquery to check if URL is valid or not. However, I can't get this to work for me. The only difference I can think of is that my URL is a text file (http://mycrossdomain.com/sometext.txt) and not HTML.I think the YQL query needs to be adjusted accordingly. Any help is appreciated.
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 2 processes: 1 is writing to a sqlite database, 1 is reading from the same database. Occasioally, I get SQLITE_BUSY on my selects. Is this normal? Is their some option or way I could open the database so that it blocks until it CAN complete the query? (I tried the FULLMUTEX option on the open call but it appeared to have no effect).
I am trying to write a query to select all records from users table where User_DateCreated (datetime field) is = 3 months from today.
Any ideas? Thanks!
hi guys,
I am upgrading from vb6 to vb.net.
I used to list my query results in datagrid in my previous applications. What can be more visually attractive control in replacement of datagrid?
I hate the classic look of datagrid
With this query, I get a result that is two short of the table because they are not included in count, and I would like get the NULL values in the result. To do this, I am pretty sure I need to use a subquery of some kind, but I am not sure how, since the attribute in question is an aggregate.
SELECT Equipment.SerialNo , Name, COUNT(Assignment.SerialNo)
FROM Equipment
INNER JOIN Assignment
ON Assignment.SerialNo = Equipment.SerialNo
GROUP BY Equipment.SerialNo, Name
I have one 'Transaction' entity object with 'Operations' navproperty with multiplicity of 'Many'.
When I'm adding only one operation per transaction nothing happens, but when I'm trying to add more than one operation,
db.SaveChanges() throws an exception like 'Subquery returned more than 1 value blah, blah, blah'
How can I solve that?
Help me guys please...
BTW... Could you tell me how can I see the exact query string that EF passes to Sql Server on db.SaveChanges() method?
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.
In mysql I am able to do this:
SELECT *
FROM table
WHERE auth_user.lastactivity > NOW() - 100
now in postgresql I am using this query:
SELECT *
FROM table
WHERE auth_user.lastactivity > CURRENT_TIMESTAMP - 100
but I get this error:
operator does not exist: timestamp with time zone - integer
How can I resolve ?
DECLARE @STR_IDS VARCHAR(15)
SET @STR_IDS='7,15,18'
UPDATE TBL_USERS WHERE ID IN @STR_IDS
I know the update statement would not work as the ID is of type INT and i am replacing a varachar value there .How can i change the query so that it will be executed like this in effect ?
UPDATE TBL_USERS WHERE ID IN (7,15,18)
Thanks in advace

Is there a quick query I can run that returns all columns of the same name between two tables?
I have many pairs of tables that I know are tied together, but I'm not sure which of the 50 or so columns they have in common.
My Scenario is...
I want to find out whether the table has an identity column or not.Table is unknown to me.I have not done the structure of the table.using Query?
Im using Sql Compact.
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 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?
I have query like below
declare @str_CustomerID int
Insert into IMDECONP38.[Customer].dbo.CustomerMaster
( CustomerName , CustomerAddress , CustomerEmail , CustomerPhone )
values ( ‘werw12e’ , ‘jkj12kj’ , ‘3212423sdf’ , ‘1212121'
)
select @str_CustomerID= scope_identity()
after execution it returns null in my parameter
i want to get value of identity how can i do that
