I have create a sales delivery printout with the following example information example below gives a delivery and the two sales orders that delievry is related to.
Two tables are T1 = delivery, T2 = orders
Delivery (T1)
linenum Item delievry Qty Ordernum orderlinenum DeliveryNumber 1 A 10 600 1 5001 2 B 5 600 2 5001 3 c 12 605 1 5001 4 P 1 5001
ORDER (T2) number 600
linemum Item OrderQty orderno 1 A 20 600 2 B 10 600 3 A 5 600 ORDER (T2) number 605 linemum Item OrderQty orderno 1 C 20 605 2 B 20 605 3 F 5 605
I want to print a delivery note with the all items on that delivery (delivered items) plus other items on orders which ware not delivered. so the result of the query should look like below
Result NO Item delievry Qty Ordernum orderlinenum ORDER QTY 1 A 10 600 1 20 2 B 5 600 2 10 3 c 12 605 1 20 4 P 1 5 A 600 3 5 6 B 605 2 20 7 F 605 3 5
You can ignore the first column of results which is just the row number.
other conditions
1. Some times the delivery is not based on any sales order 2. Delivery can base on 0,1,2,3 or any number of sales orders. 3. result should provide all rows from the delivery and all rows from sales orders except the rows in the delivery.
I have 3 tables: Â TABLE [dbo].[Tbl_Products]( [Product_ID] [int] IDENTITY(1,1) NOT NULL, [Product_Name] [nvarchar](50) NOT NULL, [Catagory_ID] [int] NOT NULL, [Entry_Date] [date] NOT NULL,

I am using this query to get ( Product name from tbl_products , Buy Price - Total Price- Total Quantity from Tbl_Details )
But am getting a multiple result if the order purchase has more than 1 item :
SELECT DISTINCT B.Product_Name,A.AllPieceBoxes, A.BuyPrice,A.TotalPrice,A.BuyPrice FROM Tbl_Products B INNER JOIN Tbl_PurchaseHeader C ON C.ProductId=B.Product_ID INNER JOIN Tbl_PurchaseDetails A ON A.PurchaseOrder=C.purchaseOrder WHERE A.PurchaseOrder=3
Hi all,Just after some help with a query (Stored Procedure) I've managed to get wrapped round my head.The DB is as such:
COMPANY Company_id Company_name COMPANY_GROUP Group_id Group_name USER User_id User_name Bridging tables
COMPANY_GROUP_BRIDGE company_id group_id
USER_COMPANY_BRIDGE user_id company_id Basically, the only parameter I have for the query is a User_id.I need to get the Group linked to the User and return all the companies within that group. I've tried reading up on all the join types again but have just got this completely wrapped round my neck. I keep thinking along the lines of SELECT all the companies linked to all the groups linked to all the companies linked to the User_id :s I must be able to do this without using two Company tables...? Any help much appreciated,Pete
I have Categories table with CategoryID, Title, CategoryParentID columns Questions table with QuestionID, Text columns CategoriesQuestions table with CategoryID, QuestionID columns Now I want to make the query which takes QuestionID and return all Categories of that provided QuestionID. I already have made that query in 2 different styles. First I make an Inner Join to retrieve the results Select Categories.* from Categories Inner Join CategoriesQuestiosn on Categories.CategoryID = CategoriesQuestions.CategoryID where CategoriesQuestions.QuestionID = 1 Second I make a sub query to retrive the results. Select * from Categories where CategoryID In (Select CategoryID From CategoriesQuestions where QuestionID = 1) Now I am asking what is the better one in respect to performance. And please provide any other query if you have.

For a given day, in this example 3/5 if I were to just select all the records I would get back around 550,000. If I put the filter on where I tell it to just show me one account its snappy. If I remove that filter and have it show me all the accounts it take forever. Here is the layout of my positions table where i am pulling the majority of the information:
CREATE TABLE [dbo].[positions]( [account_id] [int] NOT NULL, [security_id] [varchar](50) NOT NULL, [position_date] [smalldatetime] NOT NULL, [quantity] [decimal](18, 5) NOT NULL, [cost] [decimal](18, 5) NULL, [security_price] [decimal](18, 5) NULL, [acm_ctf_mtf_price] [decimal](18, 9) NULL, CONSTRAINT [PK_positions] PRIMARY KEY CLUSTERED ( [account_id] ASC, [position_date] ASC, [security_id] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]
GO SET ANSI_PADDING OFF
My questions is if you can identify any reason why the query might take more than 10 minutes (actually still running after 10 minutes) to complete when I have it bring me back all the records, not sure if its a lack of indexes or what, but was hoping for some suggestions on what I might be missing. I apologize if I havent included enough information, still learning how to troubleshoot the performance side of things.
Not sure if this is right place to ask but here is our problem. We are getting records from more than one table. Table1 and Table2 for example Both Tables haveid, value table11, 201, 30 Table 21, 501, 40 here is the queryselect table1.id, table1.value, table2.value from Table1inner join Table2on Table1.id = table2.idproblem is this returns 4 rows like this1, 20 , 501, 30 , 501, 20 , 401, 30 , 40 When we need it to return1, 20 , null1, 30, null1, null, 401, null , 50 any help on this would be appreciated.Thank You in advance.
Hi all.I want to use the following query in a sp to enable paging using ObjectDataSource.The problem (being EXTREMELEY slow) arises when I add these joins and where statements.

I wrote a SQL query that firstly do an outer-join for two table and after I add another table with outer-join as well. I'm getting the following message: Server: Msg 301, Level 16, State 1, Line 1 Query contains an outer-join request that is not permitted. May be someone knows what is it? If I remove the second join- it work....
Ok I have a complex query that works great, but now I need to join yet another table but the problem is, the value that links it to the rest of the query is a value that is returned from a case statement earlier in the query...
For Example...
SELECT var1, var2, var3, CASE T1.Number WHEN 0 THEN T2.Result ELSE T3.Result END as var4 FROM TABLE1 T1 LEFT OUTER JOIN TABLE2 T2 on T2.Value=T1.Value LEFT OUTER JOIN TABLE3 T3 on T3.Value=T1.Value2
Above is a generalized, much smaller example of my working Query. Now what I need to do is join TABLE4 but the value I need to connect it to the rest of the query is var4, which can come from 2 different places depending on the value of T1.Number
Basically the logic I need to make it work is to either have a case statement in my JOIN. Like, 'LEFT OUTER JOIN TABLE4 on T4.Value=(CASE T1.Number WHEN 0 THEN T2.Result ELSE T3.Result END)'
Is this even possible and if so, how? I need to keep the logic in the main query to preserve performance...

Hi,I have a view(A) and I am trying to do a join on another table (B) toinclude only rows where date values in view A is greater than in tableB. I also want the view to pick up rows in viewA based on date values.Here is what I have so far:SELECT *FROM viewA vwleft JOIN tableB tb ONvw.id = tb.id and(vw.date1 > tb.date1 orvw.date2 > tb.date2 orvw.date3 > tb.date3)WHERE vw.date4 > getdate()-1Not matter what kind of join I use I can get both the rows from theview where dateA > getdate()-1 AND where date1-3 are greate than intableB. Dates 1 - 4 seperate date fields. Could someone please tellme what I am doing wrong.Thanks.
HelloLet me explain the problem I am having:I have two tables, data_t and a_data_ta_data_t is the archive table of data_tThe two tables are exactly the same.In the table values are stored:Value (A numeric value)Code (A text code to identify a report with data)Line (The line number)Col (The Col Number)EDate (The date of entry)Grp (A number of a group the data belongs to)I want to get the value from data_t minus the value from a_data_t withthe same Code, Line and Col but with a different EDate (To view thevariance).Here is my statement:select d1.line, d1.col, (IsNull(d1.value,0) - IsNull(d2.value,0)) asvalue from data_t d1full outer join a_data_t d2 on d1.Code = d2.Code and d2.line = d2.lineand d1.col = d2.colwhered1.Code = 'XC001' and d1.line between 1 and 20 and d1.grp = 26and d1.EDate = '2006/06' and d2.grp = 26 and d2.EDate = '2006/05'order by d1.line, d1.colIt works fine EXCEPT when there is a value in either of the tables thatisn't in the other one, then a value is not given.Example:data_t doens't have a value for line=1 and col=2 and grp=26 and Code ='XC001' and EDate = '2006/06'a_data_t has the value of 50000 for the same details (Except Edate of'2006/5')Instead of returning -50000 it doesn't return anything.I hope I could explain it correctly.Any help will be greatly appreciated.Thanks.
Hello.... i have 4 tables in a databse(tab1,tab2,tab3,tab4). id is the attribute of TAB1 and id also foreign key of all the tables.....That mean id attribute exists on all the tables........so when i want to query to more than 1 table , i have to go for Joins...basically i am using innerjoin......... Can u tell me is there any other way to find the same output as the innerjoin......without using the keyword INNER JOIN for example ......SELECT * FROM TAB1 INNER JOIN (TAB2 INNERJOIN TAB3 ON TAB2.ID=TAB3.ID) ON TAB1.ID=TAB2.ID
another query........ SELECT *FROM TAB1,TAB2,TAB3 WHERE (TAB1.ID=TAB2.ID) AND (TAB2.ID=TAB3.ID) AND (TAB3.ID=TAB1.ID) above queries are same or not??????????

I have a single table named PROCESS which contain following three fields
ProcessID ParentID, info
* Every process have a unique ProcessID and ave single parent process which is identified by ParentID.
* If a process does not have a Parent then its ParentID value is -1.
*Only single level of Parent-child hierarchy is maintained.
