Beginner's Question: How To Write This Query
Jul 14, 2007
Hi -
I feel stupied b/c I can't figure this out but I hope it's just a few seconds for some of the more senior posters of this forum:
I have a table that looks like this:
Table:Request
ID: bigint
... (a bunch of table specific columns)
User_Status_ID: bigint (holds the bigint ID of the status table, below; always holds the ID to the most recent ID, if several)
Provider_Status_ID: bigint (holds the bigint ID of the status table, below; always holds the ID to the most recent ID, if several)
and then there is a second table that looks like this:
Table: Status
ID: bigint
RequestID: bigint (the request ID, so I can see all status messages for the request)
Time: Timestamp
Code: byte (there are only a few status messages)
The status table holds both the status for users and providers, as they use exactly the same status code. What I'd like to get is a table/view that looks like this:
RequestID:bigint (the request that this status belongs to)
User_Code: byte (the code of th most recent user status)
Provider_Code: byte (the code of the most recent provider status)
Somehow, I am blanking how to create a query that returns both user and provider codes in one row. Any help greatly appreciated!!!!

I have a query returning the Average of an Integer with a precision of zero. However because of this in my query and export I am only returning whole numbers for my Average.
Is there anyway in the query to modify the field for what I want to view so that it will return decimals?
Thanks in advance.

I'm an Absolute beginner to SQL
I have a table of baseballTeams with columns baseballTeamName and a baseballTeamID
A have another table (baseballGames) which consists of baseball games which includes a homeTeamID and a visitingTeamID.
Both of these columns are linked to the baseballTeamID from the baseballTeams table
I have been successful at joining the two tables and Selecting the baseballTeamName from the baseballTeams table for either the hometeam or
visiting team as shown below:
SELECT gameID, homeTeamID, baseballTeamID,baseballTeamName
FROM baseballGames, baseballTeams
WHERE baseballGames.homeTeamID=baseballTeams.baseballTeamID
...but I cannot figure out how to select BOTH the homeTeam name and the visitingTeam name from the baseballTeam table
Any help would be greatly appreciated
Thanks in advance

Say I have the following table:
ID Type Name
--- -------- ---------------
1 1 Michael
2 1 Julian
3 2 Catherine
4 2 Julia
5 2 Silvia
6 3 John
What SQL query should I use in order to get the following output:
Type Name1 Name2 Name3
------- ----------- ------------ ------------
1 Michal Julian NULL
2 Catherine Julia Silvia
3 John NULL NULL
I believe this is a very basic question, but I can't seem to find the answer anywhere.

ok i have table1, table 2 and table 3.
these table have some common feild names. table1,2 and 3 all have a,b,c and d as field names. each table has other field names too but the ones they all have in common are a,b,c and d.
so i would like to write a query that returns all rows from all 3 tables where column d is greater than 5 and less than 10.
so basically i want it to treat the records from all 3 tables ad one big dataset.
how would i write a query to do this.
i know i could say:
SELECT a,b,c,d
FROM table1,table2,table3
but what gets me is the WHERE clause
do i have to say WHERE table1.d >5 AND table1.d <10 OR table2.d>5 AND table2.d <10 OR table3.d>5 AND table3.d <10
??
any guidance please?

I have a table with many records in it. There is one field called "Nature". How would I select the value that appears the most often in the "Nature" field? The nature field contains text.
For example, this code selects those with more than 10 records...
I just want the top record.
SELECT count(*) FROM WEBASGN_FULL GROUP BY NATURE HAVING count(*) > 10
Basically select nature from webasgn_full that occurs the most often in the table....

I need help on writing a query which will return my results as I need them.
I have three tbls.
TimeType, TimePlan and TimeSpent
TimeType simply lists the Individual Jobs (types) a user can be doing.
The TimePlan and Time Spent each list individual records with start and end dates and what TimeType was being performed.
Each TimeType can have multiple starting and ending dates for the TimePlan and Timespent.
I need my results to show individual timetypes, with the starting and end dates for the Timeplans and also the TimeSpent
EG:
TypeType | TimeplanStart | TimeplanEnd | TimeSpentStart | TimeSpentEnd
Writing | 01/02/2007 | 02/02/2007 | |
Writing | | 03/02/2007 |
So there will be multiple Types, and for each one I need to show the start and end dates.
I would normally write this as three seperate queries.
The first would get the TimeTypes,
The second the TimePlan starting and ending dates for that type,
The third , the Spent starting and ending dates for that type
However that doesn't come across as very efficient so I wonder if there was any other alternative

hi guys,
I run into this question again. Here is it.
I have two tables like this:
StoreVisit(StoreVisitID(PK), UserID, StoreID, LoginID, LogoutID)
ProductOrders(ProductID, UserID, StoreID, OrderQuantity, StoreVisitID)
What I want to do is, I need to find out the lastest store visit record and put the StoreVisitID into ProductOrders table for the same userID, StoreID. So what I tried is:
update ProductOrders set StoreVisitID=sv.StoreVisitID
from ProductOrders po
inner join (select top 1 * from StoreVisit where UserID=po.UserID and StoreID=po.StoreID order by StoreVisitID desc) sv
on po.StoreID=sv.StoreID and po.UserID=sv.UserID
Where po.UserID=@UID and po.StoreVisitID is null
When I run it, it shows the error:
The column prefix po, does not match with a table name or alias name used in the query.
Looks like it does not recognize the po in select top 1... .
I hope you guys already understand what I am trying to do. I am wondering what is the best way to do this?
Thanks.

I'll start by giving the basic idea of the data structure I'm looking at in the database (pardon my MS Paint skills!):
And this all starts with a root plan. So (taking projects out of the picture for the minute), it could be a structure going any number of levels down like so: plan -> goal -> strategy -> plan -> goal -> strategy -> plan -> goal -> strategy, etc.And not forgetting, that a strategy can also have any number of projects, and all these relationships are one to many, so it ends up being like a large tree structure.
What I am trying to accomplish is user security related, in that I need to enforce rules set to say whether a single user is allowed to view a project. You can define the rules at any level in the structure above. So if for instance, a user is given a rule that they can access anything from a goal, they can see any projects that exist in any strategies underneath that goal in the tree structure. I hope this is making sense so far... The rules can also just be defined at a specific project level.
These rules (at the moment, I'm more than happy to change if this is a silly way of doing it) are set in a table that has the columns:user_id intplan_id intgoal_id intstrategy_id intproject_id intallow bitEvery row will have a user_id value, and one of either a plan_id, goal_id, strategy_id or project id (which I thought would be a simple way to pull out what kind of rule if needed), and the allow column just defines if it's an allow or deny rule (a specific deny rule on any object lower in the tree structure will override any cascaded allow rule).
The way my application needs to grab this information, is to simply have some way of returning a list project_id values for which the current user is allowed to access. I'm basically stumped. The closest I have gotten (which still didn't quite work) was going to end up using quite a large number of cursors... Which is bad. It can be inefficient to an extent, as once these values are gathered once, I can store them in a Session variable, so it's not grabbing them every time the user tries to load a project.
Thanks for any help!

CA01-004 02/11/2000
CB02-001 01/01/2001
CB02-002 02/01/2001
ID is grouped by first four characters CA01 or CB02, then each record increased by 1 to be 001, 002 .. untill 999 in sequence
How do I write SQL query just to get each group largerest record such as for our case:
CA01-004 02/11/2000
