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.
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?
I have 2 tables, I will add sample data to them to help me explain...Table1(Fields: A, B)=====1,One2,Two3,ThreeTable2(Fields: A,B)=====2,deux9,neufI want to create a query that will only return data so long as the key(Field A) is on both tables, if not, return nothing. How can I dothis? I am thnking about using a 'JOIN' but not sure how to implementit...i.e: 2 would return data- but 9 would not...any help would be appreciated.
I need to run a DELETE query based on 2 tables. I can't use JOIN with delete queries, so how do I do this?
What I initially tried to do was:
Code:
DELETE FROM tblProductState JOIN tblProduct ON tblProduct.id_Product = tblProductState.id_Product WHERE tblProductState.id_State = 54 AND tblProduct.id_ProductType = 1
Basically, I need to delete FROM tblProductState, WHERE tblProductState.id_State = 54 AND tblProduct.id_ProductType = 1
How can I do this without using JOIN. Use a sub-query? How?
SELECT ISNULL(count (agencyCandidate.JobID) ,0) as Total, MAX(RecJobAds.PostedDt) as PostedDt, MAX(RecJobAds.JobTitle) as JobTitle, RecJobAds.JobId, MAX (AgencyCandidate.AgencyId) as agentID, MAX(RecJobAds.AdStatus) as status, MAX(RecJobAds.CompanyId) as CompanyId, MAX(RecJobAds.RecId) as RecId FROM RecJobAds LEFT JOIN AgencyCandidate ON RecJobAds.JobId = AgencyCandidate.JobId GROUP BY RecJobAds.JobId ORDER BY Total ASC
i have the above query. but i would like to join in a third table, where my query is
Code:
select * from RecruiterMA where Activated = '1'.
anyidea in which place i can put the second query in the first query? thank you very much!
I have to queries I need to combine with a left join and I am having trouble figuring out the syntax. I need to join the first query with a query that contains Unions. The queries need to by joined on File_NBR which is contained in vw_SBC_Employee_Info, vw_ADPFile and SBC_Best_Scores.

Hello,There are 2 tables A(bot_id,bot_date,gomA,gomB) B(gom_id,hist_date, gom_name) table B holds the names for gomA and gomB in tableA.I wish to select A table and inner join to it gom_name for gomA and gomB IDs.The problem begins when in table B there is multiple values for gom_id, with difference names.So, to retrieve the correct B.gom_id, there is 2 conditions. first bot_date>B.hist_date and after this, if we still gets multiple records then the top record will be selected (order by date) Any ideas?
I really need some help. I'm going nuts. I been trying to get this to work all morning and i cant get it it work. the simple version is I am trying to join these two sql queries and make them one.
Code:
SELECT news. * , CONCAT( users.user_fname, " ", users.user_lname ) AS org_author FROM news LEFT JOIN users ON news.news_author = users.user_id WHERE news_id =41
SELECT CONCAT('users.user_fname', 'users.user_lname') *AS edit FROM users WHERE users.user_id=54
my previous attempts are
trouble with query.
I have a news table which has the ID of the original author and a column for the author who last edits the news article. both columns store the id of the author.
now when I'm editing the article I want to get the name of the author from the users table.
I have done a left join to get the first author (original author) but I'm having a real hard time trying to get the name of the author who last edited the record.
they both need to lookup the user_fname and user_lname fields from the users table.
my current sql is below
Code:
SELECT news.*, CONCAT(users.user_fname, " ",users.user_lname) AS org_author FROM news LEFT JOIN users ON news.news_author=users.user_id WHERE news_id=41
which gives me
Code:
news_id *news_subject *news_article *news_author *news_date *news_edited *edit_author *org_author * 41InterclubBunbury IC club has asked us all to attend a inter...771090247547109041836254Adam Green
Now how do i adapt it to get the name of the author to last edit the article? do I do a sub query another left join ??? every way I try doesn't work.
this is what I'm currently trying to get it with.
Code:
SELECT news. * , CONCAT( users.user_fname, " ", users.user_lname ) AS org_author FROM news LEFT JOIN users ON news.news_author = users.user_id LEFT JOIN (
SELECT CONCAT( users.user_fname, " ", users.user_lname ) AS edit_author FROM news WHERE news.edit_author = users.user_id ) WHERE news_id =41
Heres a different approach that I thought would work
Code:
SELECT news. * , CONCAT( users.user_fname, " ", users.user_lname ) AS org_author FROM news LEFT JOIN users ON news.news_author = users.user_id LEFT JOIN (
SELECT concat( users.user_fname, users.user_lname ) AS edit FROM users WHERE users.user_id =54 ) AS edit WHERE news_id =41
but no i get this error
Code:

I also tried

but got this error

can anyone help me with this query its been driving me up the wall all morning.
how do I add in a 3rd and 4 table to the mix and get their sums and group by ...The top select works fine the lower one is what I was thinking is this.....
Select Distinct P.CustID, P.Acct, P.Title, P.FirstName, P.LastName, A.Trips, A.MoneySpent, A.Bal FROM dbo.Cust P INNER JOIN (SELECT CustID, Sum(Days) as Trips, SUM(MoneySpent) as MoneySpent, Sum(Balance) as Bal FROM dbo.CAsh Where Accumulator='DP' GROUP BY CustID) A ON P.CustID = A.CustID
The 2 new tables are ViewDis (X) - Sum (Distance)and ViewACC (Y) Sum Fields required Hours, Min, (Group by) Building and Date.
Select Distinct P.CustID, P.Acct, P.Title, P.FirstName, P.LastName, A.Trips, A.MoneySpent, A.Bal, X.Distance, Y.Hours, Y.Min, Y.Building FROM dbo.Cust P INNER JOIN
i have two tables field1 is the primary key: table1 -------------------- field1|field2|field3 ---------------------
table2 --------------------- field1|field4|field5 --------------------- what we need is to get the results based on field1 matching datas, but is also a requirement that if there is no matching data in field1 of table2 w.r to table1 we just need to return table1 datas with null values for table2 fields.
is that possible, i used inner, right joins but all in vain.

Hi,I have a question regarding join query syntax:In my DB there are Users table, and Transactions table (which has'TransactionDate' and 'UserName' fields). I would like to display alist of all users (each user will appear only once), and for each user- his last transaction date.Please advice.Thanks,Yaron
Hello, There are 2 tables A(bot_id,bot_date,gomA,gomB) B(gom_id,hist_date, gom_name)
table B holds the names for gomA and gomB in tableA. I wish to select A table and inner join to it gom_name for gomA and gomB IDs.
The problem begins when in table B there is multiple values for gom_id, with difference names. So, to retrieve the correct B.gom_id, there is 2 conditions. first bot_date>B.hist_date and after this, if we still gets multiple records then the top record will be selected (order by date)
Here is an example for what I wish to get: A has following values (1,'2007-02-04', 1,2) B (1,'2007-02-02','Name1') ; (1,'2007-02-09','Name2');(1,'2007-01-01','Name3') ; (2,'2007-02-01','Name4') ; (2,'2007-02-03','Name5')
Let's say A.bit_id=1, then, the bot_date is 2007/02/04, gomA=1, gomB=2, then the query will return from B table one record that answers 2 condition: A.bot_date>B.hist_date ('Name1' and 'Name3' ) , then from this records 'Name1' will be selected because this is the maximum date.
That's all was for gomA and now we need the name for gomB=2; bot_date is 2007/02/04 and so rows 'Name4' and 'Name5 are qualified, from this two records the biggest date is 'Name5''
and so, Name1,Name5 will be return by the function.
I guess the TOP function and the INNER JOIN can help here but I just failed to create such query...
Now I have the following query to get the data from both tables.
select b.Security_ID, b.Source_Code, b.Best_Bid, a.Best_Ask, b.Import_Date from @tblBestBidsForToday b left join @tblBestAsksForToday a on b.Security_ID = a.Security_ID and b.Source_Code = a.Source_Code and b.Import_Date = a.Import_Date
I would like to get all the data from both tables. But it seems that this query does not fully work. Because there may be records in the first table and not in the second or vice versa.
There may be a source_Code with an import_Date in the first table, this source_code can be present in the second table but not with all the same Import_Dates.
CURRENT RESULT (which is not quite correct): Note, in @tblBestAsksForToday, this record does not appear in the RESULT 125 GFI01 113.1250 2007-11-28 07:29:00
PaymentMethod table contains the following fields:
PaymentMethodID PaymentMethod ClearanceCharge
ProductSale table contains the following fields:
ProductSaleID UnitCost CheckoutID
Assume the PaymentMethod table contains the following data:
PaymentMethodID PaymentMethod ClearanceCharge 1 Cash 0 2 Maestro Dom 0.565 3 Electron 0.35 4 Solo 0.345 5 Visa Delta 0.37 6 Mastercard 0.195 7 Visa 0.195 8 Amex 0.266
I want to calculate sum(ProductSale.UnitCost) where PaymentMethod is NOT equal to Cash or Amex. I have mocked this up and it seems to work:
Code SnippetSELECT Checkout.CheckoutDate, Sum(ProductSale.UnitCost) AS ValueOfSales, Count(*) AS NumberOfSales, Sum(Checkout.ClearanceCost) AS StreamlineCost FROM Operator INNER JOIN (Checkout INNER JOIN ProductSale ON Checkout.CheckoutID = ProductSale.CheckoutID) ON Operator.OperatorID = Checkout.OperatorID WHERE (((Checkout.PaymentMethodID)=2 Or (Checkout.PaymentMethodID)=3 Or (Checkout.PaymentMethodID)=4 Or (Checkout.PaymentMethodID)=5 Or (Checkout.PaymentMethodID)=6 Or (Checkout.PaymentMethodID)=7)) GROUP BY Checkout.CheckoutDate ORDER BY Checkout.CheckoutDate DESC;
I also want to calculate sum(ProductSale.UnitCost) where PaymentMethod=Amex. Again, I have mocked this up and it seems to work:
Code SnippetSELECT Checkout.CheckoutDate, Sum(ProductSale.UnitCost) AS ValueOfSales, Count(*) AS NumberOfSales, Sum(Checkout.ClearanceCost) AS AmexCost FROM Operator INNER JOIN (Checkout INNER JOIN ProductSale ON Checkout.CheckoutID = ProductSale.CheckoutID) ON Operator.OperatorID = Checkout.OperatorID WHERE (((Checkout.PaymentMethodID)=8)) GROUP BY Checkout.CheckoutDate ORDER BY Checkout.CheckoutDate DESC;
These queries only return results where the ValueOfSales and NumberOfSales is not zero... i would like them to return results for each day even if the result is zero...
Also, I want the results from both queries as one result set i.e. I want the results to look like:
