Fan of Sub's and I feel more comfortable doing them, I've been told they aren't as efficient as JOIN's by another developer. Is this true?
Also, does one or the other perform better on SQL Server vs. Oracle? I'm more seasoned as an Oracle developer and have learned to avoid JOIN's when ever possible. So I guess my real question is have I been led astray?
:o
Thanks in advance, DBA's Rule!
SQL Server 2000Howdy All.Is it going to be faster to join several tables together and thenselect what I need from the set or is it more efficient to select onlythose columns I need in each of the tables and then join them together?The joins are all Integer primary keys and the tables are all about thesame.I need the fastest most efficient method to extract the data as thisquery is one of the most used in the system.Thanks,Craig
View 3 Replies View RelatedI recently learnt that there is a different approach to create "Joins" whilst developing an ASP .Net application. Usually i have databases that have relationships (JOINS) created etc so i never did this e.g. if i wanted to retrieve data from another table i would have done something like this:
JOIN - What I use to do....
SELECT Products.ProductID, Products.ProductName, Products.SupplierID, Products.QuantityPerUnit, Products.UnitPrice, Products.UnitsInStock,
Products.UnitsOnOrder, Products.ReorderLevel, Products.Discontinued, Categories.CategoryName, Suppliers.CompanyName,
Products.CategoryID
FROM Products INNER JOIN
Categories ON Products.CategoryID = Categories.CategoryID INNER JOIN
Suppliers ON Products.SupplierID = Suppliers.SupplierID
Today i learnt this:
Sub Query without JOINS
SELECT ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued,
(SELECT CategoryName
FROM Categories
WHERE (CategoryID = Products.CategoryID)) AS CategoryName,
(SELECT CompanyName
FROM Suppliers
WHERE (SupplierID = Products.SupplierID)) AS SupplierName
FROM Products
The second code (Sub query) seems to be easily readable but fairly difficult to create to a certain degree. So my question is which method should i use for development purposes? Is there any real difference or just ok to use whichever im comfortable with?
Thanks in advance
I have a query that works fine in SQL Server,
SELECT TC.[TestId]
,TS.[NameId]
,[regressionLevel]
,Mstr.[MethodId]
,users.[UserId]
FROM [db_db].[dbo].[TEST] TC
join
[NEW_DB].[dbo].[Users]users
on
users.FirstName=TC.Username
join
[New_DB]..[Method_Master] Mstr
on
Mstr.Description=TC.Method
join
[New_DB]..[TestSource] TS
on
TS.Name = TC.TestName
basically there is a join between three tables to repalce all the varchars to the corresponding ID.
Please guide me in how should I go about in designing my SSIS package to achieve this requirement.
thanks in Advance

Please help, I cannot figure out what is wrong
Hi, i have a vb.net here i have 2 timers. one look every night at 2 o'clock pm and make a backup of my sql server express database to drive c:
In the Program runs at this moment some other action and another timer that checks different things and write this to the sql database .
are the some things that i have to pay attention when i make the backup ?
Or is it equal when i make a backup and at the same time i write data ?
hello ppl.......

We find that a delete command on a table where the rows to be deleted involve an inner join between the table and a view formed with an outer join sometimes works, sometimes gives error 625.
If the delete is recoded to use the join key word instead of the = sign
then it alway gives error 4425.
625 21 0 Could not retrieve row from logical page %S_PGID by RID because the entry in the offset table (%d) for that RID (%d) is less than or equal to 0. 1033
4425 16 0 Cannot specify outer join operators in a query containing joined tables. View '%.*ls' contains outer join operators.
The delete with a correleted sub query instead of a join works.
Error 4425 text would imply that joins with view formed by outer joins should be avoided.
Any ideas on the principles involved here.
Hi,
Why is it that SQL joins (*=) run a little faster as opposed to ANSI joins(LEFT JOIN...)? Aren't they supposed to be almost identical?
The issue is this: we are promoting using ANSI syntax for the obvious reason (future versions of SQL Server may not support SQL Server syntax; portability, etc.)
However, the problem is the speed. What have others done about this? Do you use ANSI syntax or SQL syntax? HOw true is it that future SQL Server versions may discontinue support for the '*=" and "=*' join operators.

I have four tables which I want to return results for an advanced search function, the tables contain different data, but can be quite easily joined,
Table A Contains a Main Image, this image is displayed in the results
Table B Contains an Icon, this image is displayed in the results
Table C doesn't have an image in it but has a child table with a number of images associated to the table, in the UNION ALL statement I would Like to do a Join to get say the top Image from this child and print it for the row associated with table C.
Select title, description, image from tableA
UNION ALL
Select title, description, icon as image from tableB
UNION ALL
title, description, ( inner Join SELECT top(1)
from imageTableC where imagetableC.FK = tableC.PK)
as image from tableC
Could someone show me the syntax to do this, I have all the information printing to the screen, bar this table C image.
Hi All,
Im having a problem with a statement i cannot seem to get 2 left joins working at the same time 1 works fine but when i try the second join i get this error:-
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC Microsoft Access Driver] Syntax error (missing operator) in query expression 'children_tutorial.school_id=schools.idx LEFT JOIN regions ON children_tutorial.region_id=region.idx'.
My SQL statment is as follows :-
SELECT children_tutorial.*,schools.schoolname,regions.rname FROM children_tutorial LEFT JOIN schools ON children_tutorial.school_id=schools.idx LEFT JOIN regions ON children_tutorial.region_id=region.idx
I am using an Access database i have tried all sorts to get it working and its driving me mad!! any help would be really appreciated.
HelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)
View 1 Replies View RelatedWhen I add a constraint to the where part of the SQL statement below it will only show the nc_department.department where siteid equals it.

JOIN MUDDLE
Soory if this is a bit basic, but I'm chasing my tail:
I have two select statements:
SELECT MyRows from Table1 where X = 1
SELECT OtherRows From Table 2 Where y = 3
I want to produce a LEFT JOIN between the result of each query, and return the resultant rows
I know this is not correct syntax:
(SELECT MyRows from Table1 where X = 1)
LEFT JOIN
(SELECT OtherRows From Table 2 Where y = 3)
ON
Tabel1.Row1 = Table2.Row2
but I think it illustrates what I want to do
If I do the WHERE after the join I only get where there is a righthand table
I cant get the syntax right, an example with the correct grammar would be very much appreciated
I am trying to figure out which Option is the best/fastest and why?
I have simplified the query a lot. The actual query consists of lots of tables.
OPTION A (the search for the specific id is in the JOIN)
select * from table A left join table B on a.id = b.id and a.id in (1,2,3)
OR
OPTION B(the search for specific id is in the WHERE clause)
select * from table A left join table B on a.id = b.id
where a.id in (1,2,3)
Could somebody please tell me why we should never mix old-style and ANSI-style joins in the same query? What would be the consiquences?
Thank you
Instead of inserting into, how can I use a join of multiple
tables to update a table.
This is the join that inserts.
INSERT INTO [table] (MyID, material, dollars)
SELECT l.MyID, material, dollars

Tab_Special_tox r ON l.MyID = r.MyID
Thanks in advance
can somebody give a good explanation of uisng a self join with an example
that would really help

Microsoft SQL Server 2000:
I am not a SQL programmer, but I am trying to use data collected in our Job Costing system to feed data to a crystal report that summarizes the current department name and the last date each job was scanned into a department.
I used aliases of the Process table to extract the max date for each department.
This statement works fine, but sometimes it hangs and locks my process table. I am not sure what event causes the lock, but I think it has to do with the users aborting the report during the SQL extract or multiple users trying to report at the same time (8am when they first arrive at work).
I showed this to a consultant and he showed me that the MAX statement in the 3rd to last join was eating most of the execution time. Also he told me I am using too many joins and should look into Table Views. The statement completes in 15 to 45 seconds, depending on the workload.
What can I do to improve the performance of this code and to avoid the locks?

i have two tables each table having 2 column
table1 table2
eid ename eid ename
1 A 3 C
2 B 4 D
i shld use a select query to get the following output
eid1 eid2
1 3
2 4
there is no relation btw the 2 tables except that eid column of both tables r of same data type
the count of eid column in both table are also same
can a blind join be done
SQL Novice
What i want to happen is Table_A will hold a recid and an update field. within the if statement it needs to JOIN with Table_B ON recid and check the value of one/two possible fields to determine if that recid goes to Table_F or Table_G
I need to get this INNER JOIN embedded in a nested if along with more INNER JOINs
INSERT BACKFILE_AP
SELECT WORK_INTRO.RECID, WORK_INTRO.UPDATED
FROM WORK_INTRO INNER JOIN SIF_DT1
ON WORK_INTRO.RECID = SIF_DT1.RECID
WHERE SIF_DT1.ROUTE_CODE = 'BACKFILE'
DELETE WORK_INTRO
FROM WORK_INTRO INNER JOIN SIF_DT1
ON WORK_INTRO.RECID = SIF_DT1.RECID
WHERE SIF_DT1.ROUTE_CODE = 'BACKFILE'
Heya -
Very new here to SQL, but when I do this following query
SELECT ProjMgr, SUM(Fee) AS Fee
FROM dbo.PR
WHERE (ProjMgr = '00138')
GROUP BY ProjMgr
I return these results:
ProjMgrFee
001389145297
Simple enough, so I flex my newbie SQL muscles and put in the last name instead of the ProjectManager's employee number
SELECT dbo.EM.LastName, SUM(dbo.PR.Fee) AS Fee
FROM dbo.PR INNER JOIN
dbo.EM ON dbo.PR.ProjMgr = dbo.EM.Employee
WHERE (dbo.PR.ProjMgr = '00138')
GROUP BY dbo.EM.LastName
And get these results
LastNameFee

Okay, NOW I'm getting cocky. I try to bring in an amount indicating held labor from another table that will have multiple instances of the same number, called WBS1, and show a sum of values contained over months of history in a sum. Before I do that, I add the table, and then I'm stuck - look what happens to my fee column...any ideas?
SELECT dbo.EM.LastName, SUM(dbo.PR.Fee) AS Fee
FROM dbo.PR INNER JOIN
dbo.EM ON dbo.PR.ProjMgr = dbo.EM.Employee INNER JOIN
dbo.LD ON dbo.PR.WBS1 = dbo.LD.WBS1
WHERE (dbo.PR.ProjMgr = '00138')
GROUP BY dbo.EM.LastName
RESULT
LastNameFee

Hi All,
I had a query like
Select * from Fact1
UNION
Select * from Fact2
JOIN
(Select top(col1),... from Fact3
INNER JOIN Table1
group by Col2
) ON....
The above one was executing in 5 minutes
I changed the inner query to say
Select Quarter,top(col1),... from Fact3
INNER JOIN View1
group by Quarter,Col2
I have made sure that the inner query is returning the same set of rows before and after modification. But still the modified query runs for ever. I am refering 2 databases(both SQL Server 2000 databases, on the same server- including the current). Please also note that I had a inner join to a table which I have changed to a view in the inner query.
I suppose this is due to the change in the execution plan. What should I do to make this work?
Any ideas?

I am very new to SQL and I have a question about inner joins. By using a lookup table and a row function, I have the following question and code. I am not sure if it right or not. I would appreciate any assistance:
For every type of food in the l_foods table, list the following:
The full name of the supplier from the l_suppliers table. The description of food from the l_foods table The price from the l_foods table plus the price_increase from the l_foods table; rename it to total_price
When price increase is null, assume that the 10 cents will be added to the price. Sort this information ty the total price.
SELECT a.supplier_name,
b.description,
b.price_increase AS total_price
FROM l_suppliers AS a, l_foods AS b;
Orange- l_foods table
Blue - l_supplier table
Red - within both tables.
That is far as I got without error.
Select * from
table1
left join
table2
on table.id=table2.fid
where
table2.column3 >5
is there any significance in the left join
or inner join is enough
Hi all,
What is happening internally when a join is performed ?.
Why there are two outer joins as both of them performing the
same opertion?.Use left join key word and swap the tables , its will
perform a right join .Is that correct?
Thanks in advance

which web site can explain (entry level) difference between inner join and outer joins? I have looked many of them all the levels and their explanation is not easy to understand.
