I have table 'products' and I need to update 'price' field by 20% if product 'type' field is "imported".
How do I read and update field at the same time in my UPDATE query?
Hello,
I've been playing today with stored procedures. I'm stoned that I picked the basic of it up so easily. (I'll also try triggers very soon).
Now, I'd like to know how to save my SPROC under the stored procedure folder (Programmability - Stored Procedure) so that I can access it by name (eventually from my C# application). So far, when I press the save icon, I'm proposed to save the whole query. That's not what I want.
Thanks for helping
I apologize for the vague title. I am attempting to write a query that returns an alias column with matching values (resulting from an IN) as well as an alias column with values that do not match (using NOT IN). I want the result set to have: userId | matches | nonmatches. I currently have the following query which returns the matches as expected. I am having trouble getting the nonmatches in the result set -- that is, from a NOT IN statement
SET @userId = 9;
SELECT ug.user_id, COUNT(DISTINCT goal_id) as matches
FROM user_goal ug
WHERE ug.user_id!=@userId
AND goal_id IN (SELECT iug.goal_id FROM user_goal iug WHERE user_id=@userId)
GROUP BY user_id ORDER BY matches DESC LIMIT 4
So, the NOT IN would look something like this:
goal_id NOT IN(SELECT uggg.goal_id FROM user_goal uggg WHERE user_id=@userId) AS nonmatches
I am just not sure how to incorporate the NOT IN statement in my query so I get all the results

How can I do a search for value A in column1 and add a value B in column2?
In other words for every record that column1 has the value A I want to make the value in column2 = B (Currently column2 is empty)
Would this work?
UPDATE MyTable
SET Column2 = REPLACE(Column2,NULL,'B')
WHERE Column1 = "A"
Hi, I'm here again-
I have something like this
Select A.a, A.b, A.a+A.b as c, (A.a+A.b*2)+A.d as d from Table
But i want to know, if it is possible, to make it work with something like this:
Select A.a,A.b,A.a+A.b as c, (c*2)+A.d as d from Table
Thank you
Call me pedantic but is there a more elegant way to combine all those checks?
SELECT * FROM [TABLE1]
WHERE [path] = 'RECEIVE'
AND [src_ip] NOT LIKE '10.48.20.10'
AND [src_ip] NOT LIKE '0.%'
AND [src_ip] NOT LIKE '127.%'
ORDER BY [date],[time] DESC;
To something like this:
SELECT * FROM [TABLE1]
WHERE [path] = 'RECEIVE'
AND [src_ip] NOT LIKE IN ('10.48.20.10','0.%','127.%', .... )
ORDER BY [date],[time] DESC;
[HttpPost]
public void Test(HttpPostedFileBase file)
{
UsersContext db = new UsersContext();
byte[] image = new byte[file.ContentLength];
file.InputStream.Read(image, 0, image.Length);
CrimeReport i = new CrimeReport
{
ImageId=1, ImageName="Anjli",ImageContent = image,
Active=true
};
db.CrimeReports.Add(i);
db.SaveChanges();
}
I am getting an exception on db.CrimeReports.Add(i);
Hi Guys,
I have a trigger that sends an email once a value has been changed.
It works when i make any amendments but when the users make the changes it fails.
I have figured out the users havnt got permission to send mails in master.dbo.xp_sendmail
The way the DB was originally setup wis shocking!! (each user has a network login rather than being part of a network group)
Is there anyway i can allow a role in customerDb to access the xp_sendmail proc in the mater db?
Thanks

I'm interested in finding the most precise decimal values in a database field. I'd like to be able to sort results by descending precision. Is this possible?
e.g.
10.1781253
12345.12435
89.763
1.1
2
CREATE OR REPLACE PROCEDURE p_createLocaltable
IS
table_already_exist EXCEPTION;
PRAGMA EXCEPTION_INIT (table_already_exist, -00955);
BEGIN
create table local_table as
select * from supplied_table
where rownum < 1;
EXCEPTION
when table_already_exist then
DBMS_OUTPUT.put_line('Table already exists , does not need to recreate it');
END;
can anyone see any problem of the above code?
I have a long running stored proc (approx 30 mins) which is currently running within a transaction (isolation level snapshot).
I've set the transaction to snapshot to avoid locking records preventing other processes from accessing the data.
What I'm trying to do is write to and read from a status table, but although we're in a transaction I'd like to write to and read from the status table as if I'm not in a transaction. I need this so that other processes can read any updates to this table by my stored proc, and this stored proc can also read any inserts made by other processes.
I realise that having my entire stored proc running within a transaction isn't recommended, but this has been done for other reasons and we need to stick with that approach.
So my question is within a transaction, is it possible to execute a query or call a stored proc which effectively isn't enlisted in the transaction?
I'm looking for an example of a good update trigger to update the ModifyDate field of a table.
It would be nice to handle the case where an update command updated more than one record in the table.
Is there a good template or tutorial for this?
Thanks
How do I calculate number of years since product was made (rounded to 1 decimal point) for products that were made less than five years ago? Thank you.
Actually if i am doing INNER JOIN of two tables then i will get all matched records from the two tables.
But i want to get all the unmatched rows only.
Is there any way to do that?
Or Any JOIN available for that?
