for example two columns of table1 , have relation to the id column of table2
for example:
tbl_city: (id , title)
tbl_person: (id , name , CurrentCityID , LastCityID , ...)
now , I want to make two relations from tbl_person to tbl_city
CurrentCityID and LastCityID must relation to tbl_city
this query is wrong:
SELECT tbl_person.name , tbl_city.title , tbl_city.title
FROM tbl_person
JOIN tbl_city ON tbl_person.CurrentCityID = tbl_city.id
JOIN tbl_city ON tbl_person.LastCityID = tbl_city.id
can you help me ?

Yes, but you may want an AND instead.

Maybe you ar looking for aliases in sql queries?
I think this query is the right one for you:
SELECT
person.name as personName, currentCity.title as currentCityTitle, lastCity.title as lastCityTitle
FROM tbl_person as person
JOIN tbl_city as currentCityON person.CurrentCityID = currentCity.id
JOIN tbl_city as lastCity ON person.LastCityID = lastCity.id
Note the as keyword used in the querry.
I have no smart signature yet...

I've always left the as out.

That is a common practice, but in the previous example I assumed the questioner has no or little knoledge about aliases, therefore I followed a more explicit approach.

Hi Friend,
I have one question about database management...
I have one Procedure which take 30 min to execute....
I have crate front end for that Process, the scenario is when user press the button to execute that Procedure but find no response and close the browser what happen for that procedure after this, i mean that procedure is executed but did't stop....that procedure is using server resource but unmanaged how to managed that.
Thanks and regard's in advance.

In case of SQL server 2008, the stored procedure won't execute if the calling program is stopped. Which database or you speaking of?
|
|
|
|
|
i am talking about sql Server 2005...
|
|

I believe it should also behave the same way. You can try to replicate the scenario using following in the stored procedure:
waitfor delay '00:00:10'
insert into SomeTable values ('some value')
This will cause a delay of 10 seconds before the insert. While SQL is waiting for the delay to get over, you can stop the calling application of yours and then check if the insert happened.
BTW is 30 min execution time expected or not? If not, you can check the execution plan and it would give you an idea why so much time is taken.
|
|
|
|
|
First and foremost, what user is going to sit there and wait for 30 minutes for the query to execute? I would spend my time optimising the query rather than worry about what happens WHEN the user closes the browser.
Anyone who has a stored proc taking that amount of time to execute while a user sits waiting deserves any and all problems which they get from it.

Hi, thanks for looking
I need to sort the results of my query, lets say i have the following values in my Articles table
Id, Title
--------------------------
1, "The less you talk..."
2, The long and...
3, -ABC of Math
4, *Something else
The result should look as follows:
3, -ABC of Math
4, *Something else
1, "The less you talk..."
2, The long and...
Notice that the title may o may not have or may have more than 1 special character at the beggining
Thanks in advance for any help

Ok, I did this:
DECLARE @Table AS Table(
ID Int,
[Name] nVarChar(50))
INSERT @Table(ID, Name)
VALUES(1, '"The less you talk..."')
INSERT INTO @Table
SELECT 2, 'The long and...'
INSERT INTO @Table
SELECT 3, '-ABC of Math'
INSERT INTO @Table
SELECT 4, '*Something Else'
SELECT * FROM @Table
ORDER BY (SELECT CASE WHEN (UNICODE(SUBSTRING(Name,1,1))< 123)
THEN UNICODE(SUBSTRING(Name, 2,1))
ELSE Name End) ASC
Result:
ID Name
-----------------------------
3 -ABC of Math
4 *Something Else
1 "The less you talk..."
2 The long and...
The results match what you specified, but what if there is more than one 'special' character at the beginning of the string?
EDIT:
If you add more data you will find the following:
DECLARE @Table AS Table(
ID Int,
[Name] nVarChar(50))
INSERT @Table(ID, Name)
VALUES(1, '"The less you talk..."')
INSERT INTO @Table
SELECT 2, 'The long and...'
INSERT INTO @Table
SELECT 3, '-ABC of Math'
INSERT INTO @Table
SELECT 4, '*Something Else'
INSERT INTO @Table
SELECT 4, '? A Question'
INSERT INTO @Table
SELECT 4, '#Regions'
INSERT INTO @Table
SELECT 4, 'Sometimes you are right.'
INSERT INTO @Table
SELECT 4, 'Little creatures'
SELECT * FROM @Table
ORDER BY (SELECT CASE WHEN (UNICODE(SUBSTRING(Name,1,1))< 123)
THEN UNICODE(SUBSTRING(Name, 2,1))
ELSE Name End
) ASC
Result:
ID Name
-------------------------------
4 ? A Question
3 -ABC of Math
4 #Regions
4 *Something Else
1 "The less you talk..."
2 The long and...
4 Little creatures
4 Sometimes you are right.
This may not be ideal...

Thanks for the reply
Its a good start, but it looks like you are only taking into account the first character and in case it is a pecial symbol you take the second, it wont work if you have values like these:
DECLARE @Table AS Table( ID Int, [Name] nVarChar(50))
INSERT INTO @Table SELECT 1, '"The morning..."'
INSERT INTO @Table SELECT 2, 'The long and...'
INSERT INTO @Table SELECT 3, '-ABC of Math'
INSERT INTO @Table SELECT 4, '*Something Else'
SELECT * FROM @Table
ORDER BY (SELECT CASE WHEN (UNICODE(SUBSTRING(Name,1,1))< 123)
THEN UNICODE(SUBSTRING(Name, 2,1))
ELSE Name End) ASC
Notice how
"The morning..."
appears before
The Long and...
Thanks again for your example

Yes, I have tried quite a few things. You will have to parse the data in the client and perform your sorting there. This is the correct way. The database is for data and not particularly interested in the formatting.

The best I can think of is a UDF that uses the REPLACE function to strip those characters. You could add this on a separate view on the table, including the column only when needed- as it would be a very expensive operation (looping all characters for each record).
It might be better (performance-wise) to store a redundant version of the Title, without any special characters.

Hi!
I need to move a database from one server to another.
So I have the server 'S1', the database 'DB1' which is located on the server 'S1' and the server 'S2'. I use MS SQL Server 2005 Express.
I carried out following actions:
1) executed stored procedure sp_detach_db 'DB1' on server 'S1'
2) copied files DB1.mdf and DB1Log.ldf from 'S1' to 'S2'
3) tried to execute the query on the server 'S2':
CREATE DATABASE DB1
ON (NAME = DB1_data, FILENAME = 'file_path\DB1.mdf')
LOG ON (NAME = DB1_log, FILENAME = 'file_path\DB1Log.ldf')
FOR ATTACH
and recieved the error: "Unable to open the physical file "file_path\DB1.mdf Operating system error 5".
When I executed the same query on 'S1' to attach DB1 again it was finished successfully...
Tell me please what is the source of the error? and how do I solve my problem.

Problem is solved by adding full access permisions for 'MSSQLUser' user group to the file_path directory.

There's nothing wrong with the semi-colon. What point were you trying to make, or were you just trying to be smart?

 You're right, I stand corrected; sincere apologies.
The line breaks and absence of indentation made me think the first couple of lines belonged to the same statement.
