query to get the data of three tables?

Hi:
I have three tables in my db. One is clients, other calls, and other visits.
I want to get all the calls and visits of all clients in my db every row in each table separate in one row in the results table.
How can I do it?
Use the SQL JOIN functionality:
http://www.w3schools.com/sql/sql_join.asp
|||You can do this a couple of ways,
Let's say the tables look like this:
table calls
clientid,
calldate
table visits
clientid,
visitdate
table client
clientid,
clientname
You can get all of the data in one row by joining the three tables together, or you can get all of the calls data and all of the visits data (in separate rows) by using a union query.
First inner joining:
select c.ClientName, call.CallDate,visit.VisitDate from calls call inner join clients c on c.clientid = call.clientid inner join visits visit on c.clientid = visit.clientid
now for the union
select c.clientname, 'call' as type, call.calldate from clients c inner join calls call on c.clientid = call.clientid
union
select c.clientname 'visit' as type, visit.visitdate from clients c inner join visits visit on c.clientid = visit.clientid
Is this what you were looking for?
Hope this helps,
|||thanks so much.
The second one is exactly what i was looking for.
Thanks again

Query Timeout

Hello,
Our system has experienced time out issues with on of the SQL Severs. We
have an ASP.NET application that calls a stored proc, which returns a result
set. This stored proc all of a sudden started to time out on Friday after
noon. I was able to execute the same procedure in Query Analyzer without any
problems. The timeout for My ASP.NET is 30 seconds and the query was
executing the Query Analyzer in less than 30 seconds.
The solution I found out for this is to update statistics on one of the
databases. The stored proc has a join with a table in different database
sitting on the same server. When I updated the statistics of this database
the ASP.NET app started behave normally. This time I did not run the update
stats, instead I was thinking to do more research this morning. To my
surprise, the time out issue went away and ASP.NET is working absolutely
fine. What I found is that the SQL server might have been rebooted this
weekend.
Now I am scratching my head and trying to figure out what could be the
problem. What is it'
I appreciate any comments.
ThanksIf you have SQL Server configured to auto update stats, it may have done an
update itself which improved the stats and allowed it to create a good query
plan again.
My experience has been that auto update is not reliable enough, so we
schedule update statistics ... with fullscan against all tables across the
course of a week.
