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.
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.
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)
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
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
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:
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.
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
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.
I'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?
CREATE VIEW update_bd_view AS select D.BD_ID, D.BD_DESC, T.BT_TYPE_TID, T.BT_TYPE_FID, T.BT_JOB_FID FROM BILLING_DESC D JOIN BILLING_TIME T ON D.BD_ID=T.BT_ID GO
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.
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
Two tables:FruitfruitID, fruitNameBasketbuyerID, fruitID(ie. we can see which buyer has what fruit in their basket)I simply want to display all available fruit and whether or not it'sin a specific persons' basket.SELECT Fruit.fruitID, Fruit.fruitName, IsNull(buyerID, 0)FROM Fruit INNER JOIN Basket ON Fruit.fruitID = Basket.fruitIDWHERE Basket.buyerID = 12but this just gives me what's in buyer 12s' basket.What am I doing wrong? Am I a basket case...
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

Any help in explaining where I have gone wrong here would be greatly appreciated.
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?
SELECT task1_.Start as y0_, count(this_.FirstName) as y1_ FROM t_contact this_ inner join t_task task1_ on this_.TaskId=task1_.Id GROUP BY task1_.Start
I was writing a query using both left outer join and inner join. And the query was ....
SELECT Â Â Â Â Â Â Â S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Â Â Â Â Â Â Â Production.Suppliers AS S LEFT OUTER JOIN Â Â Â Â Â Â (Production.Products AS P Â Â Â Â Â Â Â Â INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT Â Â Â Â Â Â Â S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Â Â Â Â Â Â Â Production.Suppliers AS S LEFT OUTER JOIN (Production.Products AS P LEFT OUTER JOIN Production.Categories AS C ON C.categoryid = P.categoryid) ON S.supplierid = P.supplierid WHERE S.country = N'Japan';
The result i got was same,i.e
supplier   country   productid   productname   unitprice   categorynameSupplier QOVFD   Japan   9   Product AOZBW   97.00   Meat/PoultrySupplier QOVFD   Japan  10   Product YHXGE   31.00   SeafoodSupplier QOVFD   Japan  74   Product BKAZJ   10.00   ProduceSupplier QWUSF   Japan   13   Product POXFU   6.00   SeafoodSupplier QWUSF   Japan   14   Product PWCJB   23.25   ProduceSupplier QWUSF   Japan   15   Product KSZOI   15.50   CondimentsSupplier XYZ   Japan   NULL   NULL   NULL   NULLSupplier XYZ   Japan   NULL   NULL   NULL   NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.
OLEDB source 1 SELECT ... ,[MANUAL DCD ID] <-- this column set to sort order = 1 ... FROM [dbo].[XLSDCI] ORDER BY [MANUAL DCD ID] ASC
OLEDB source 2 SELECT ... ,[Bo Tkt Num] <-- this column set to sort order = 1 ... FROM ....[dbo].[FFFenics] ORDER BY [Bo Tkt Num] ASC
These two tasks are followed immediately by a MERGE JOIN
All columns in source1 are ticked, all column in source2 are ticked, join key is shown above. join type is left outer join (source 1 -> source 2)
result of source1 (..dcd column) ... 4-400-8000119 4-400-8000120 4-400-8000121 4-400-8000122 <--row not joining 4-400-8000123 4-400-8000124 ...
result of source2 (..tkt num column) ... 4-400-1000118 4-400-1000119 4-400-1000120 4-400-1000121 4-400-1000122 <--row not joining 4-400-1000123 4-400-1000124 4-400-1000125 ...
All other rows are joining as expected. Why is it failing for this one row?
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.
Why would I use a left join instead of a inner join when the columns entered within the SELECT command determine what is displayed from the query results?
I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?
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?
We are trying to migrate from sql 2005 to 2012. I am changing one of the implicit join to explicit join. As soon as I change the join, the number of rows returned are fewer than before.
INSERT #RIF_TEMP1 (rf1_row_no,rf1_rif, rf1_key_id_no, rf1_last_date, rf1_start_date) SELECT currow.rf0_row_no, currow.rf0_rif, currow.rf0_key_id_no, prevrow.rf0_start_date, currow.rf0_start_date FROM #RIF_TEMP0 currow LEFT JOIN #RIF_TEMP0 prevrow ON (currow.rf0_row_no = prevrow.rf0_row_no + 1)
[Code] ....
the count returned from both the queries is different.
I am not sure what am I doing wrong. The count of #RIF_TEMP0 is always 32, it never changes, but the variable @countTemp is different for both the queries.
Why does this right join return the same results as using a left (or even a full join)?There are 470 records in Account, and there are 1611 records in Contact. But any join returns 793 records.
select Contact.firstname, Contact.lastname, Account.[Account Name] from Contact right join Account on Contact.[Account Name] = Account.[Account Name] where Contact.[Account Name] = Account.[Account Name]
Is there a way to do a super-table join ie two table join with no matching criteria? I am pulling in a sheet from XL and joining to a table in SQLServer. The join should read something like €œfor every row in the sheet I need that row and a code from a table. 100 rows in the sheet merged with 10 codes from the table = 1000 result rows.
This is the simple sql (no join on the tables):
select 1.code, 2.rowdetail from tblcodes 1, tblelements 2
