ive seen so many ways to do this, including some using cursors (strange i know)
but i have tableA and tableB i want to show fields from tableA which don't apear in tableB
what is the MOST efficient way to do this
In a single table I have 2 columns. Date | Number2006/09/01 - 2352006/09/03 - 2452009/08/01 - 230 I want to write a query that will return the AVG number between two dates. I am assuming this will require a JOIN but I'm having problems implementing my solution. I think about it, it's probably not a join but a sub query...I was trying the following: SELECT Date, AVG(Number) as AVERAGE_NUMBER
FROM test.Table
WHERE ( Date>='09/01/2006' AND DATE<='09/04/2006' ) But I keep getting date is invalid in the select list because it is not contained in either an aggregate funtion or a group by clause. Thanks in advance for your help.
Hi,We are in the process of buying a new server to run mssql. Howeverbefore this as a tempory fix to using a msaccess backend i believethrough odbc i need to address the following issue:SELECT ai.entry_date as CallTime,ai.agent_login as AgentsLogin,ai.campaign as MarketingCampaign,ai.agent_input2 as ProductsSold,ai.first_name as Cust_FirstName,ai.last_name as Cust_LastName,ai.agent_input1 as Cust_PersonalNumber,ai.street_address as Cust_AddressStreet,ai.city as Cust_AddressCity,ai.state as Cust_AddressState,ai.zip as Cust_AddressZIP,rec.file_name as AgreementRecordingFileFROM agent_input ai, leads l, recordings recWHERE ai.whole_phone_number = l.whole_phone_number ANDl.call_status = 1110 ANDrec.whole_phone_number = l.whole_phone_number ANDrec.last_name = l.last_name ANDrec.agent = ai.agent_login ANDrec.campaign = l.campaign ANDlast_call_date between #04/24/2006 12:00 AM# and #04/25/2006 11:59 PM#ORDER BY ai.agent_login, ai.entry_dateI want to make the recordings entry optional so the same results comeout whether it matches a recording or not. If it does i want it topopulate the AgreementRecordingFile column above, if not just put a ''as you would with '' as AgreementRecordFile.Does anyone know how you can do this, in a access based database systemusing SQL through i believe ODBC?ThanksDavid

I've a big problem by using the following query :

I am receiving funny results from a query. To simplify, I have 2 tables (todayyesterday). Each tbl has the same 8 columns. My query joins the two tables then looks where either of two columns has changed. What is happening is that when checking one of the columns it seems as though sql is flipping the column, causing it to be returned in error.
result set
colA colB colC colD colE colF colG colG (from yesterday)
1 1 a b c d e m
1 1 a b c d m e
So what's happening is that the record above is actually the same record and should not be returned. There is a daily pmt column that changes but I am not using that in the query. Aside from that the two records are identicle.
Any help is appreciated.
Hi,
I have the following situation (with a site that already works and i cannot modify the database architecture and following CrossRef tables -- you will see what i mean by CrossRef tables below)
I have:
Master table Hotel
table AddressCrossRef (with: RefID = Hotel.ID, RefType = 'Hotel', AddrID)
joins
table Address (key = AddrID)
table MediaCrossRef (with RefID = Hotel.ID, RefType= 'Hotel', MediaID)
joins
table Media (with MediaID,mediaType = 'thumbnail')
foreach hotel, there definitely is a crossRef entry in AddressCrossRef and Address tables respectively (since every hotel has an address)
however not all hotels have thumbnail image
hence i have hotel inner join AddressXReff inner join Address ..... however i must have
left outer join mediaXref left outer join media
the problem is that if there is no entry in Media or mediaXref, I don't get any results
i tried to get over it by using
where (media.mediaTyple like 'thumbnail' or media.mediaType is null)
but then i started getting multiple results for each hotel because media's of type movie or full_image or etc... all got returned
any clue?
thanks
I don't know if it's Friday or what, but I can't for the life of me come up with an easy way to do this:
I have 3 tables I want to join:
Sale Table:
Sale_No Cus_No Sale_Qty
1 Joe01 250
Order Table:
Ord_No Sale_No Order_Qty ShipToCode
1 1 20 DestA
2 1 20 DestA
3 1 20 DestA
4 1 20 DestB
5 1 20 DestB
ShipTo Table:
Cus_No ShipToCode ShipToName
Joe01 DestA Philadelphia
Joe01 DestB Chicago
Bob01 DestA Boston
A sale for say 100 tons would have 5 orders (each for 20 tons) associated with it by Sale_No. Each of those orders can go to a different ShipTo destination. Since only the ShipTo Code is stored in the Orders table, I need to get the ShipToName. However, As demonstrated in the example table above, the key in the ShipTo table is both Cus_No AND ShipToCode.
I want a list of Sales and Orders, which is an inner join on Sale_No, piece of cake. However, I then need to use the ShipTo table to go from the ShipToCode to the ShipToName. Unfortunately, Cus_No is not in the Orders table, it is back in the Sales table (proper normalization is a pain sometimes).
What I came up with is this, but is this correct?:
FROM Sales INNER JOIN
Orders ON Sales.sale_no = Orders.sale_no INNER JOIN
ShipTo ON Orders.ShipToCode = ShipTo.ShipToCode AND
Sales.cus_no = ShipTo.cus_no
Hi Guys,
I have the following table called VMailMessages:
PHP Code:
MessageNum MailboxNum State
========================
1 100 1
2 101 1
3 101 1
4 102 0
Which is of messages in a mailbox system, the MessageNum is my primary key, MailboxNum indicates which mailbox it is for and State indicates whether it is 'New' (value = 1) or 'Saved' (value = 0).
What I want to do is write a query to obtain a list of mailboxes, along with how many New and how many Saved messages they have, producing a result table like this:
PHP Code:
MailboxNum NewCount SavedCount
===========================
100 1 0
101 2 0
102 0 1
My problem is I cannot seem to get my SQL right, so far I've got:
PHP Code:
SELECT NewQuery.MailboxNum, NewQuery.NewCount, SavedQuery.SavedCount
FROM (SELECT MailboxNum, COUNT(1) AS NewCount
FROM VMailMessages
WHERE (State = '1')
GROUP BY MailboxNum) NewQuery
FULL OUTER JOIN
(SELECT MailboxNum, COUNT(1) AS SavedCount
FROM VMailMessages
WHERE (State = '0')
GROUP BY MailboxNum) SavedQuery
ON NewQuery.MailboxNum = SavedQuery.MailboxNum
WHich works only if the mailbox has New messages as well as Saved messages. For mailboxes with only Saved messages, the count appears but, the MailboxNum is NULL. The opposite occurs if I change my SELECT clause to ask for SavedQuery.MailboxNum, but I really want both.
Can anyone help me?
Thanks

I feel like this is an easy question, but I can't describe it well enough to find the answer I need by searching. Anyway, in my spare time (I'm definitely not a SQL Query pro) I'm putting together a small app for our local Little League to help with scheduling.
I have 2 tables I need to join:
T1 = Schedule
has the following fields:
ID
hTeamID (ID of Home team)
vTeamID (ID of Vistor team)
Time
Date
T2 = Teams
ID
Name
Other info...
I want to be able to do a SELECT statement on the schedule table and JOIN the team names for both home and visitor. I've tried a bunch of different ways but keep getting errors. I can think of 100's of reasons to join the same table more than once, but I still don't know how to and can't find the answer online.
Thanks in advance.
I have listed two tables table 1 has some data. I have to update table 2 [reports] column from table 1 [reports] using self join..I should get as table 2 after updating
View 1 Replies View RelatedI've got a simple ( I think) question on views. I've got a view that has a table join in it.
With this view, we want to be able to perform updates, inserts, and deletes. At this time
we can do the updates and inserts, but not deletes. I've checked the permissions and
the users have SELECT, INSERT, UPDATE, and DELETE. Am I missing something or are
deletes just not possible in a view with a join?

Hi Everyone,
I have a simple question regarding outer join.
Please see the attached word file. It has screen shots of the query I am running. My first query shows the result where i have M.ReservationID = MA.MeetingID and it counts NoofRSVP (# of times the query runs). I have to modify first query in such a way that it returns records from eCDReservations table even if there is no matching MeetingID in MeetingAttendees table (means Null, see the result of 2nd query in attached file). So in my result for that case NoofRSVP column should show either Null or 0.
Ok here is the situation. I have 2 tables.
Movies
MovieID Title Year
21 A Beautiful Mind 2002
22 Forrest Gump 1994
23 The English Patient 1999
Actors
ActorID MovieID Name
1 22 Tom Hanks
2 21 Russell Crowe
3 23 Ralph Fiennes
4 NULL Nachiket Mehta
Here is the SQL Query.
SELECT ActorID, Name, Title, Year FROM Actors LEFT OUTER JOIN Movies ON Actors.MovieID = Movies.MovieID
Now, I only want to show movies made in 1990's and display all 4 actors. If I put
WHERE Year < 2000
it won't show the fourth actor because he doesn't have any movies. I need to show all 4 actors here and NULL for movies if they don't have any.
Hope this makes sense. Thank you.

I am currently studying Transact SQL and playing around with queries from a sample database. Recently I created the following query.
USE MemtrackSQL
SELECT m1.MemberID, m1.Surname, m1.FirstName, m1.DateOfBirth
FROM tblMember m1 JOIN tblMember m2
ON m1.FirstName = m2.FirstName
WHERE m1.MemberID <> m2.MemberID
This simple query is designed to show all members with the same first name as other members. The result I got shows duplicates of existing members an inconsistent number of times even though I specified not to show duplicates with WHERE m1.MemberID <> m2.MemberID

Ok, I have two tables with a child/parent or one -> many relationship:
parent_table:
pid int primary key
pname varchar
child_table:
cid int primary key
pid int
cname varchar
Say the contents of these two tables are:
parent_table:
pid pname:
1 Ben
2 Jesse
3 Michael
child_table
pid cid cname
1 1 ben_Child1
1 2 ben_Child2
1 3 ben_Child3
2 4 jesse_Child1
2 5 jesse_Child2
2 6 jesse_Child3
3 7 michael_Child1
3 8 michael_Child2
3 9 michael_Child3
Now what I would like to be able to do is:
select pname, cname
from
parent table a,
child_table b
where a.pid = b.pid
Except! Instead of getting the results in the form of:
Ben ben_Child1
Ben ben_Child2
Ben ben_Child3
...
I would like them in
Ben ben_Child1 ben_Child2
Now normally this would be impossible (I think) since the query would return an unknown number of columns. But in this case I only care about the FIRST TWO children for each parent. So I'm sure there's some way to do this with a simple select, but I don't know how. Anyone?

I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table.
The makeid and orderdate belong to the OrderDetails table.
The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
I'm using SQL Server 2005.
A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).
The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).
If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.
If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.
So, this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
and this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC
But this does't:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
What should I be looking for here to understand why this is happening?
Thanks,

I hope it's considered appropriate to post a SQL query question here; it's not I'll gladly post this question elsewhere. That having been said, I've run into a simple but quite tricky SQL query and was wondering if the community might be able to help. Here's what's going on:
I have a "Documents" table. Let's call it DI have a "Benefits" table. Let's call it B.There is a many-to-many relationship between D and B so I have a third table to store the relationships. Let's call that table BD.
When I create a document it creates a row in D. Let's call that D1, D2...DN. When I create a benefit it creates a row in B. Let's call that B1, B2...BN
When I associate a document to a paritcular benefit, let's say that if D1 and B2 are associated, that I created row B2-D1 in my BD table. Now here's what my challenge is. Suppose I have these entries in my tables:
D: D1, D2, D3B: B1, B2, B3
Table BD:B1-D1B2-D1B2-D2
When the user goes to add documents to benefit B1, I want to show the user only documents that are not yet added to B1. In this case, I want to show the user D2 and D3 but not D1 since that one's already added. How do I write a SQL query to do this?
Here's what I've been using, but it shows too many results (e.g. included D1, D2, D3)
SELECT D.*, BD.*FROM Documents AS d LEFT JOIN rel_BenefitsDocuments AS bd ON d.doc_id = bd.doc_idWHERE (benefit_id <> @benefit_id OR benefit_id IS NULL)
Any thoughts?

This should be easy, I'm just having a brainfart at the moment, can't remember how to do this:
Say I have a bunch of records in a table, with an ID field as Key. I want to return the count of times each ID shows up, so for the following example data:
Code:
-----
| ID |
-----
| 1 |
| 2 |
| 1 |
| 4 |
| 1 |
| 4 |
------
Would return something like:
Code:
----------------
| ID | Count |
----------------
| 1 | 3 |
| 2 | 1 |
| 4 | 2 |
-----------------
This should be obvious but for some reason I can't see it.
When this is done I'm going to join in another table to get a name based on the ID with the highest count. I believe it's faster to do a TOP 1 here rather than after the join, but I want to verify that while I'm at it also.

I have two tables ... I am trying to get only the rows that are different.
Hi folks,
I am a complete newbie to SQL. I have a simple query to make in SQL, but I'm not being able to construct the statement properly. I've already tried googling this info, but with little luck. If someone could help me here, I'd be very thankful.
The problem:
I have a table with a list of questions. All questions have a serial number. The query has to return whether a particular question is the last one in the table or not (according to serial no.)
Logically, this is the query -
Code:
select islast = 0
if count(*) from question where serialno > $serial != 0
else
select islast = 1;
The '$serial' part will get replaced dynamically before query execution through another program.
Any idea how to code this in valid SQL? I would like to make it a simple statement and not a stored procedure. Thanks.
