Hi,

I have three tables with two relations.

First table is users, which just stores userids (autonumber), and a lastseen (text).
Second table is Names. Every user has names, right? So it's just rows of userid(long)/name(text).
Third table is IPs. Every user has a few ips, right? So again, it's just userid/ip.

The relations are just the ones I mentioned, a user has names and ips.

I have a name and an ip. I want to select a union from the IPs and Names.
The union needs to have only users that have the ip given in their ips, or - here's a tricky part - have an ip with first two octets the same as the given ip but also the name must appear in the user's names.

The idea is that given a name and ip, I want to select all previously entered users who are probably the same user.
But, after finding all these users, I also want to merge everything that I found to just one user. So all the ips I found should be updated to relate to the first user found, and the same for the names.

Any ideas?

I tried this: (given name is MasterShin and given ip is 204.15.0.0)

SELECT Players.userid, Names.name as [value], 1 as [type] FROM (Players RIGHT OUTER JOIN [Names] ON Players.userid = Names.userid) LEFT OUTER JOIN IPs ON Players.userid = IPs.userid
WHERE IPs.ip = '204.15.0.0' OR (IPs.ip LIKE '204.15.*' AND Names.name = 'MasterShin')
UNION
SELECT Players.userid, IPs.ip as [value], 2 as [type] FROM (Players RIGHT OUTER JOIN IPs ON Players.userid = IPs.userid) LEFT OUTER JOIN Names ON Players.userid = Names.userid
WHERE IPs.ip = '204.15.0.0' OR (IPs.ip LIKE '204.15.*' AND Names.name = 'MasterShin')

And after the select I can go over everything, save on the side what updates need to be done, and later do them.
But this big statement seems repetitive and not efficient...

It is a little late for me, so I did not read your hole problem. Maybey tomorrow. But, youe have one table with userids and a table with usernames. Is it possible that a userid has more names? If not, why not combine those two tables to one?

Yes. Users can have more than one name.

I stil think it is strange that one user can have more names, and I still do not understand the exact problem. But maybe you can try this:

select u.UserID, <br />
[value] = case when i.ip = '204.15.0.0' then n.Name else i.ip end,<br />
[type] = case when i.ip = '204.15.0.0' then 1 else 2 end<br />
from Players u<br />
left join IPs i on u.userID = i.UserID<br />
right join n Names on u.UserID = n.UserID <br />
Where i.ip = '204.15.0.0' or (i.ip like '204.15.%' and n.Name = 'masterSin')

Hello everyone,

I would like to create a table where I keep the record of time period which refrence to an event. The time variable is in the format of Hour, Minute, Second (Three Double Digits). How can I created a table to stroe these information and still be able to run a search quary?

I don't have a problem converting the time into only one number which would be second but I rather to keep the table in the same format of column for each of the hour, minute, and second.

Thank you very much for your help.

1-What is the database that you use ? MS SQL, Access, MySQL?
2-How will your searches look like?
3-Merging the 3 columns look a good idea to me and they will be easy to separate in UI or even in SQL.

1.Create column with datetime datetype and name it MyDateTimeColumn
2. use getdate() to fill it
it will be like 28-02-2007 12:34:567
3.Use if it is helpful CONVERT(varchar(11),Mytable.MyDateTimeColumn,105)
This 105 is pamaretar and can be in range 100-114?
or from some two gidits number I think from 10 to ...try u will see

Sorry if this doesnt fit

It's used to convert a string literal to wide character.
for example. If you have a column with nvarchar and you want to compare it with a string (where mycol= 'abc') you should make it like: (where mycol= N'abc')
you'll not notice that the first will not give the expected results unless you use a language other than English (Arabic strings for example).
