OBJECTIVE:THE QUERY SHOULD GIVE ME THE FIELDS I MENTIONED IN THE FIRST QUERY WITH THE CONDITIONS BELOW.
CONDITION 1: RateReview field should have yesterday's date
CONDITION 2: Email will be send to customer only once so Customer_GUID is UniqueIdentifier
CONDITION 3: Customer shouldnt' have opted to get out from receiving any email so Termination field should be NULL
ONe Customer can have many transwactions
Is there any way i write the code specifying that no email should be sent more than once evereven if customer buys 10 tickets.
Only one email sent so i need to specify that if this email has gone to particulare CUSTOMER_GUID then Ignore that record and
do not send any email. This would be done by some tool known as StrongMail.
SELECT
CAST(a.Transaction_GUID AS varchar(36)) as Transaction_GUID,
CAST(a.Customer_GUID AS varchar(36)) as Customer_GUID,
Film_id as MovieId,
First_nm as FirstName,
Last_nm as LastName,
Email_nm as EmailAddress
FROm
Table1 where RateReview_dm >= dateadd(day, datediff(day, 0, getdate()), -1) -- Greater or same as Yesterday day
and RateReview_dm < dateadd(day, datediff(day, 0, getdate()), 0) -- Less than today's date
and
and Terminate_dm is null
(I don;t know what condition to give that same customer good should not be send email again if send once)
i don't know whether i need to create a derive table or it can work without drive table
Hi, I wanna know is there any advantage of perf gain when using Derived Tables over Temp Tables, advice me which one is better to use. Can I create Indexes and Insert/Update records into Derived Tables.
Hi, I have built a database for a university project, but am having trouble with the SQL syntax for inserting derived data from a calculation into a table. At present my SQL is; INSERT INTO MemberPayment (TotalCharge) VALUES ( [Total] ) SELECT ((MileageHistory.MileageUrban * Vehicle.EmissionsPerGramUrban) * 0.05) + ((MileageHistory.MileageCountry * Vehicle.EmissionsPerGramUrban) * 0.05) AS 'Total' FROM [NeuCar].[dbo].[MileageHistory] JOIN [NeuCar].[dbo].[Vehicle] ON MileageHistory.Registration = Vehicle.Registration JOIN [NeuCar].[dbo].[Member] ON Vehicle.UserName = Member.UserName WHERE Member.UserName = 'wenger1' AND (MileageHistory.[Date] >= CURRENT_TIMESTAMP - 30); Would anybody be able to point out where I am going wrong? I would very much appreciate any advice, Kind regards, Chima
I got an error as follows: Derived table 'A' is not updatable because a column of the derived table is derived or constant. when I tried to run this query: update A set MonthsUnbilled =99999888 FROM (select MonthsUnbilled from dbo.vw_MasterView WHERE (RecordID =8377396)) A This is a simplified query in order to pinpoint the culprit. I know I don't need to use a derived table if the real query is this simple.
Below is my sql, i am getting error msg "Incorrect sytax near 'Votes'." Can anyone tell me what im doin wrong?

Hi all,I have a table in this formatcolname1 colname2 colname3col1data1 col2data1 col3data1col1data2 col2data2 col3data2col1data3 col2data3 col3data3col1data4 col2data4 col3data4I want to display it in this formatcolname1 col1data1 col1data2 col1data3 col1data4colname2 col2data1 col2data2 col2data3 col2data4colname3 col3data1 col3data2 col3data3 col3data4Basically rotate it through 90 degrees clockwise and flip it over :)I'm pretty sure this is done by using a crosstab query and or aderived table or temp table. The problem is I use a crosstab query toget the original data into the first format. I've been strugglingtrying to get the ouptput into the second format for over a day nowand just can't seem to get it to work. Can anyone give me any pointerson the general solution to this?I hope this makes sense. Thanks for the help.
I have an application that has two different database backends, one is SQL Server Compact Edition and the other is SQL Server. The reason is because the application may run at home on one of our sales agent's computers or here in the office.
I have a query that uses a derived table and works just fine in SQL Server, however when I run it in the compact edtion (having the exact same table structures) it will not run. My question is...does the Compact Edtion or the Mobile Edition allow derived tables. If not is there a way to work around this? I will happily give an example if it will help.
I have some questions on derived table. Below is my situation.
Table order, there are 40 columns and it has indexes for productID and addressID Table product, there are 15 columns and it has index for productID Table address, there are 20 columns and it has index for addressID
Query A ------- select C.address, C.area, B.productname, B.category, A.qty, A.price from order A join product B on A.productID = B.productID join address C on A.addressID = C.addressID
Query B ------- select C.address, C.area, B.productname, B.category, A.qty, A.price from (select qty, price, productID, addressID from order) A join (select productID, productname, category from product) B on A.productID = B.productID join (select addressID, address, area from address) C on A.addressID = C.addressID
Will I loss the indexing when using derived table? Why query B performance is much better than query A?
Hi,I got another question here:I want to use query like this:SELECT * FROM (sp_lock AS T) WHERE objectID = ...The purpose is that I want to query the result set returned by sp_lockusing derived table, but it doesn't work. Why?Thanks,Baihao--Posted via Mailgate.ORG Server - http://www.Mailgate.ORG
I am working for my client on SQL 2005 Enterprise & observed a strange behaviour. Consider a table(EMPTABLE) as below:
PK, INT
VARCHAR
EMPID
EMPNAME
1
A
2
B
3
C
4
D
5
E
6
F
7
G
8
H
9
I
10
J
Now, I wanted the 5th highest EMPID from 2 from the table. Now, we know that the SQL
SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >=2 should (from all other possibilities) return me the desired value as the last row of the output table. I tried to get this in a derived table & get the MAX value i.e.
SELECT MAX(EMPID) FROM ( SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >=2 ) der
But this returns me 10, when I would've thought 7 was the expected answer
I remodified my query as mentioned below to strangely get 7 as the result... SELECT MAX(EMPID) FROM ( SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >=2 ORDER BY EMPID ASC ) der
How did the ORDER BY hep it???
Also, if I use SELECT MAX(EMPID) FROM ( SELECT TOP 6 EMPID FROM EMPTABLE WHERE EMPID >2 ) der
I get the same result without having to specify the ORDER BY in my derived TABLE...
I tried looking for similar threads. But nothing could explain this to me...
If anyone knows what I am not able to understand, please let me know.
Relative SQL newbie here......this is probably easy, but....Lets say I have a table (MainTable) that stores a list of input table names,a primary key (PKey), and a field called "Configured" for each one. Each ofthese input tables also contain a field called "Configured", which is set totrue or false in another process based on an OrderNumber. (So an order'sinputs are stored in several input tables, and the MainTable is a summarytable that shows which input tables have been configured for any givenOrderNumber).What I need to do is open each input table, and look for a record containinga specific OrderNumber and where Configured=true. If a record is found, Ineed to update the Configured field for that table in the MainTable, andthen move on to the next sub-table.The way I'm doing it now is with simple SQL and loops. Here is the basiccode (ASP):*****************************************OrderNumber = "562613" ' the current order that is being processed' reset all configured flagssql = "UPDATE MainTable SET Configured = 0"conn.execute sql, , &H00000080' get list of all tablenamessql = "SELECT InputTableName, PKey FROM MainTable WHERE InputTableName <>'---'"set rsTableNames = conn.execute(sql)while not rsTableNames.eof' test each input table for configured flagsql = "SELECT Configured FROM " & rsTableNames("InputTableName")& _" WHERE Configured = 1 AND OrderNumber = '" & OrderNumber &"'"set rs = conn.execute(sql)If Not rs.EOF Then' update the main tablesql = "UPDATE MainTable SET Configured = 1 WHERE PKey='" &rsTableNames("PrimaryKey") & "'"conn.execute sql, , &H00000080end ifset rs = nothingrsTableNames.movenextwend*****************************************There has to be a faster way.. I think.... maybe something that could bewritten as a stored procedure? I use a similar technique in a couple ofother places and it's a bit of a performance hit, especially as the numberof input tables grows.TIA!Calan
I'm trying not to use a temp table, but i may have to do so.. I'm using sql2005 for this case.
i have a derived table that makes the following results:
ID Status Name
2 1 "A"
2 2 "B"
I want to get the following:
ID Name1 Name2
2 "A" "B"
but like I said before, I can't repeat the query that gets the first 2 rows, as it's pretty invovled. a temp table is the best route I see right now, but I just wanted to be sure I'm not missing something. If I've aliased it as 'results', is there a way to alias results again as something else? or maybe a trick with CTEs? I will try that! It seems promising.

In my TSQL code i use a derived table to extract the value of account 321 to compare if they are the same that the SUM of my line invoice cost multiply by quantity line : Sum(fi.ecusto*qtt)
This is my script:
SELECT ft.ndoc [Doctype],ft.fno [Docnr] , Sum(fi.ecusto*qtt) [totalcostof my Invoiceline], xctb.conta [accountancy account], sum(Case when ft.tipodoc = 1 then Xctb.ecre else Xctb.edeb end) as [Value of Cost of invoice in accountancy], [DIF] = Sum(fi.ecusto*qtt) - Sum(Case when ft.tipodoc = 1 then xctb.ecre else xctb.edeb end)
[Code] ....
My problem is if i have more than on line on my invoice, for example 2 lines, the value of column [Value of Cost of invoice in accountancy] are duplicated, for 3 line invoice the value are multiply by 3.
When my colleague makes any change to a query containing a derived table, the word 'WITH' followed by a lot of graphical characters appears after the alias, rendering the query unusable. We have tried this with various existing and new, simple queries, all to no avail. We are editing the queries in Visual Studio 2003, and he does not get this effect when using Visual Studio 2005. I can edit the query in 2003 on my laptop with no ill effects.
I have discovered what looks like a bug in the optimiser. I've posted it at https://connect.microsoft.com/SQLServer/feedback/ViewFeedback.aspx?FeedbackID=288243 but I wonder if any of you with SQL 2005 RTM, 2005 SP1 or 2008 CTP could confirm when this was introduced and whether it is still an issue?

how to declare multiple derived columns in SSIS Derived Column Task in one attempt.as i have around 150 columns coming from Flat file. I had created the required Expression in Excel and now i want add those in derived column task but its allowing only 1 expression at a time.
I am looking for the best way in SSIS to do the following. I have an SQL table that for each row in the table I want to take an element from the table do a lookup in a Teredata Table, return information from the teredata source. Use that returned data to do some calculations and create a derived column from my calculations and place the data into the same SQL table that I am parsing through.
I am trying to get data as it is available in the table but every time I run sql statement it shows in asending order. How can I avoid this asending order situation?
I am relatively new to this and trying to make my database as efficient as possible.
Here is the situation. In my database, there are multiple "stocks" that each have a "pricing history". When something happens that changes the price of the stock, an entry containing information about the time the change occured, who changed it, etc. is added.
I have many stocks. The information of these stocks is independant in the sense that I never really need to grab/compare information about two stocks at once. I only look at one stock at a time.
So, do I set up a "pricing history" table for every single stock (pricinghist1,pricinghist2,etc.)? Or do I set up one "pricing history" table it and index the table by stock number?
Are these equivilant? Is one more efficient than the other?
(1) I have 2 packages that run independently of eachother. (2) Both are scheduled in SQLServer Agent Jobs as separate jobs. (3) Job A is scheduled to run every 12 hours and Job B is scheduled to run every 10 minutes. (4) However, I want to prevent Job B from running if Job A happens to be running. (5) It is unknown exactly how long Job A will take to finish so I can't schedule Job B around it.
The way I wanted to approach this situation is as follows.
Within Job A's package, create a "marker" file when the package starts and delete it when the package finishes. So the existence of this marker file will tell Job B's package if it should run or not.
The concept is simple, but I'm not sure how to implement this.
For example, to create the marker file, I would use a File System Task, but I don't see an option in there to "create file". (However, I do see an option for "delete file".) Also, what task would I use in Job B's package to check if the marker file exists.
Lastly, If you have better approach, I would like to hear about it.
I'm creating a database for a new application and I'm currently facing a design problem, regarding a business requierment for the membership module.
The Membership Module of the application has several business requierments, specified by the client. One of them is the ability to add and remove details about their members. So far, I've created a schema, named Person, which will contain a number of tables responsible for everything related with the membership, as an individual.
To help you guys understand the design I'm trying to implement, I'll post the fields of two of the tables that belong to the Person schema, as follows:
So far so good. This design works great to preserve the data integrety. Nonetheless, this is where the problems start. Now, imagin you need to let someone from that company add an item to the user (through the application). Let's say we want to allow the company application manager to add an item to the person called "PreviousEmployer". Such item would then be used for statics, thus would probably need to be indexed.
In order to meet this business requierment I would create some addicional tables. Let's get started:
Person.CustomFields
Id (uniqueidentifier)
Name (nvarchar(50))
Description (nvarchar(3000)) [NULLABLE]
Status (bit)
Person.CustomField_Value
FieldId (uniqueidentifier)
Value (nvarchar(450))
This could work just fine if both are indexed (that's why the nvarchar size is set to 450). But I'm guessing this is far from the optimal solution for many reasons, one of them being the efficiency of the index if the company decides to go and use this for a flag (true or false [bit]). Another "solution" breaking scenario would be if the company wants to add the CV of the person, situation in which we were unlikely to be able to add a file in this datafield.
How would you guys approach this issue? The bottom line is that the client needs to be able to add pretty mcuh any type of custom field and perform searches againts it. So, besides being a dynamic solution it needs to be efficient.
Hi, I have the following tables: Categories {Category_ID, Column2, ...} Articles { Article_ID, Category_FK, Column3, ...} Discussions {Discussion_ID, Article_FK, Column3, ...} Now, all what I have is just category_ID value (Let us say 3), how can I do cascade delete to delete category's record that its ID = 3 and delete all articles and all discussions that found in that category?
I have a very urgent situation and to do with SQL Server 6.5, cannot start and the error message I got was: Initdata: Suballocation for buffer pages failed (838860 Bytes requested. Can anyone help me urgent matter.
I need help on reproducing a deadlock. The sample that I have so far is only creating blocking and it never deadlocks. It's because I'm not sure what order the system tables are being help when creating temp tables in a transaction, therefore, I can't tell which pages need to be requested from another transaction to cause the deadlock. Any help will be much appreciated.
We have 2 SQL tables being accessed through an Access form. The tables are an ORDER table and an ORDER-DETAIL table comprised of data regarding the Parts in any given Order. (Yes -- the classic Order-Entry situation.) The Access form is used to view/create new Orders, and shows ORDER data in fields, plus has a large field which presents a "spreadsheet"-like view of the related records from the ORDER-DETAIL table.
The users enter and modify data in the ORDER-DETAIL table directly through this "spreadsheet" in the Access form. However, because there is no PARTS table yet (that's part of what I'm working on), they have to enter part numbers and descriptions *manually* in each ORDER.
So... here's my question:
After I implement a PARTS table, I would like for users to be able to open an ORDER in the Access form, type in a Part # in a row of the ORDER-DETAIL "spreadsheet", and then have the rest of the row populate with the appropriate Part description and other data from the PARTS table. How do I go about making that a reality? Some kind of stored procedure triggered by a change in the Part # field? Ha ha – if so, I am clueless as to how to make that happen. ANY information would greatly appreciated!
