SQL Server 2012 :: Get XML Output For Multiple Tables With 1:M Joins?
Jan 22, 2014Assume i have 3 tables
Person(personname,age)
Children(childname,personname)
car(carname,personname)
A persone can have multiple cars
A person can have multiple children
Its not possible to display the results in SQL rows and columns.
If i try to it will give
PersonName Carname Childname
Sachin Audi C1
Sachin Maruti C1
Sachin Audi C2
Sachin Maruti C2
Instead of writing seperate queries the application wants to receive an xml output as follows

<car>bmw</car>
<cname>c1</cname>
<cname>c2</cname>
<person>

SQL Server 2012 :: How To Get Most Recent And Oldest From Joins To A Child Table
Jul 23, 2014I have the following tables in my DB
Employee table - This table has EmployeeID, Name, DOB.
EmployeeDesignation table - 1 Employee can have many designations with each having an effective date. There is no flag to indicate which among multiples is the current entry. You can only figure it out by the newest/oldest EffectiveDate. I want to get the most recent and the oldest for each employee.
EmployeeSalaryHistory table - Structure/Design is similar to EmployeeDesignation table. I want to get the starting salary and current salary for each employee.
I want my query to output me the following fields...
EmployeeID
EmployeeName
EmployeeDOB
EmployeeStartingDesignation
EmployeeCurrentDesignation
EmployeeStartingSalary
EmployeeCurrentSalary
Here is a piece of code to generate sample data sets
DECLARE @Employee TABLE (EmployeeID INT, EmployeeName VARCHAR (100), EmployeeDOB DATE)
INSERT @Employee VALUES (101, 'James Bond', '07/07/1945'), (102, 'Tanned Tarzan', '12/13/1955'), (103, 'Dracula Transylvanian', '10/22/1967')
DECLARE @EmployeeDesignation TABLE (EmployeeID INT, Designation VARCHAR (100), EffectiveDate DATE)
INSERT @EmployeeDesignation VALUES (101, 'Bond Intern', '01/01/1970'), (101, 'Bond Trainee', '01/01/1975'), (101, 'Bond...James Bond', '01/01/1985')
[Code] ....
Currently, I have a query to get this done which looks as below. Since I have more than 8K employees with each having multiple Designation and Salary entries, my query is taking forever.
selecte.EmployeeID, e.EmployeeName, e.EmployeeDOB,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate) EmployeeStartingDesignation,
(select top 1 Designation from @EmployeeDesignation ed where ed.EmployeeID = e.EmployeeID Order By EffectiveDate Desc) EmployeeCurrentDesignation,

SQL 2012 :: Is Table Compression Suitable To Reduce I/O
Feb 11, 2015I have huge table, often I need to query the table on the whole; ie., data may required at any part of the table. So I think of to compress the table with the aim of reducing I/O.
1. is that really suitable for this requirement? If So which compression is good (Row or page )?
2. Or is there any other alternate to reduce the I/O (Except Indexing)?
3. Pros and cons ?

View 6 Replies View RelatedSQL Server 2008 :: Left Joins And Query Plan Compile Times
Mar 8, 2015We have a view with many left joins. The original creators of this view might have been lazy or sloppy, I don't know. I have rewritten the query to proper inner joins where required and also nested left joins.
So rather then the following exemplary fragment
select <many items>
from A
left join B on B.id_A = A.id
left join C on C.id_B = B.idthis now looks like
select <many items>
from A
left join (B
join C on C.id_B = B.id
) on B.id_A = A.id
Compilation time of the original view was 18s, of the new rewritten view 4s. The performance of execution is also better (not counting the compile of course). The results of the query are identical. There are about 30 left joins in the original view.
I can imagine that the optimizer has difficulty with all these left joins. But 14s is quite a big difference. I haven't looked into detail in the execution plans yet. I noticed that in both cases the Reason for Early Termination of Statement Optimization was Time Out.
DB Engine :: Linked Server - Getting Error When Performing Cross Instance Query With Joins
Apr 26, 2015I've successfully created a Linked Server that connects a local DB Engine with another DB Engine through an ip over an extranet. I am able to run simple Select statement queries on the Local DB Engine and get results from the linked server. However when attempting to perform more complex queries that join tables from the linked server with tables from the local DB server, I get the following error message after several minutes of execution:
OLE DB provider "SQLNCLI11" for linked server "<ip of Linked Server>" returned message "Protocol error in TDS stream".
OLE DB provider "SQLNCLI11" for linked server "<ip of Linked Server>" returned message "Communication link failure".

TCP Provider: An existing connection was forcibly closed by the remote host.
How I can resolve it. I've read on Distributed Transactions but I understand that it only applies to manipulation statements?
Both are SQL servers. Linked Server is SQL2008R2 if not mistaken. Local DB Engine is SQL2014.

Joins Query Help
Jun 4, 2007Hi 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
Sub Query AND Inner Joins
Feb 25, 2008I 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.

Sql Query, Several Joins

end) as MV,p.position_date,p.quantity,p.cost,p.acm_ctf_mtf_price
from positions p

order by ad.account_number,p.security_id
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.

Complex Query, Many Joins...
May 1, 2008Ok 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...
Thank you in advance,
Casey

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.

Jun 22, 2006HelloLet 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.

I want to show records as per date from Daily_Time_Entry table and detail data to be displayed as follows
dl_id dt_id project_type project_id time_st exp1 exp2 exp3 owner_name

I write query for this is as follows
Select dl. dl_id,dl.dt_id,dl.project_type,dl. project_id,dl.time_st,ac.owner_rep_id as exp1,ab. owner_rep_id as exp2,op. owner_rep_id as exp3,ow. owner_name
From Daily_Time_Entry dl left outer join
AB_Corporate_Project ac on dl. project_id = ac. ab_crp_id and dl. project_type=€™ AB Corporate€™ left outer join AB_Plant_Project ab on dl. project_id =ab. ab_plant_id and
dl. project_type=€™ AB Plant€™ left outer join Other_Project op on dl. project_id = op. other_proj_id and dl. project_type=€™ Other Project€™ inner join Owner_Rep ow on
(ow. owner_rep_id = ac. owner_rep_id) or(ow. owner_rep_id = ab. owner_rep_id)or
(ow. owner_rep_id = op.owner_rep_id)
So how can I write query to show output as follows or any other way or how to create Sql cursors for to show output
Plz help to solve this query to show output as specified.

Writing Alternative Query For Inner Joins
Jun 19, 2007Hello....
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??????????
