Hi!
I have 4 tables inner joined. Two of tables have ~500,000 rows, while other 2 have ~60,000. There are 4-5 WHERE conditions for 3 tables.
Is it normal that a query lasts ~13-15 seconds? I tried indexing in all ways, subselects, temp tables etc, nothing helped.
I think it is unuseful to use indexes because WHERE conditions apply not to one, but to 3 tables.
Is there anyone who is expert in this topic?
Thanx

Hello,
I'm working on a query for a report. I've done this before and it works, but I think it's a little slow due to the joins and I'm wondering if I'm doing this the best way.
This is from a Microsoft CRM system. I'm only using the LEAD table. There is a field on the lead table called StateCode. When a user "Qualifies" a lead, the statecode changes. The report requires a column for total leads, a column for # of leads qualified, and a column for % of leads qualified. There are other columns, but those three will illustrate the problem.
Because total leads means all statecode values are included, and Qualified leads means only one statecode value is included, I can't get those two values from the same query (that I know of). So what I do is take two queries, one for total leads, and one for qualified leads, put them in parenthesis and name them, and then join them on the name of the leadsource, like below. I often end up with 10 or 15 of these "Query Tables" in my main query. Is this the best way?
Code Block
SELECT * FROM
(
SELECT
LeadSource
, COUNT(CreatedOn)
FROM
Leads
GROUP BY
LeadSource
) as A
LEFT OUTER JOIN
(
SELECT
LeadSource
, Count(CreatedOn)
, Count(CreatedOn) / (SELECT COUNT(CreatedOn) FROM leads) AS "% of Leads Qualified from this Lead Source"
FROM
Leads
WHERE
StateCode = 2
GROUP BY
LeadSource
) as B
ON
A.LeadSource = B.LeadSource
Thanks,
Andy
I have a query written that filters on joined table data. The SELECT looks like this:
SELECT *
FROM tbl_bol AS a LEFT OUTER JOIN
bol_status AS b ON b.bol_status_id = a.bol_status_id LEFT OUTER JOIN
tbl_carrier AS c ON c.carrier_id = a.carrier_id
WHERE (a.carrier_name LIKE 'five%') AND
(a.accrueamt = 0) AND
(a.imported = 1) AND
(b.description = 'tendered') AND
(a.ship_date BETWEEN '9/1/13' AND '9/30/13')
ORDER BY a.bol_number DESC
If I want to do an UPDATE query that uses those filters in the WHERE clause, how do I go about doing that? It doesn't look like you can used joined tables in the UPDATE line like this:
UPDATE tbl_bol AS a LEFT OUTER JOIN
bol_status AS b ON b.bol_status_id = a.bol_status_id LEFT OUTER JOIN
tbl_carrier AS c ON c.carrier_id = a.carrier_id
SET accrueamt='1348'
WHERE (a.carrier_name LIKE 'five%') AND
(a.accrueamt = 0) AND
(a.imported = 1) AND
(b.description = 'tendered') AND
(a.ship_date BETWEEN '9/1/13' AND '9/30/13')
when i use the query designer and add tables it takes 15-30 mins to load a table....so if i need 6 tables in my query thats like 6 times 30 minute load times...i'm using oracle as my data source
when i switch the source to oledb it adds tables within seconds the only thing is i need to use named parameters
any ideas?
Hello,
I hope someone can answer this, I'm not even sure where to start looking for documentation on this. The SQL query I'm referencing is included at the bottom of this post.
I have a query with 3 select statements joined together like tables. It works great, except for the fact that I need to declare a variable and make it a table within two of those 3. The example is below. You'll see that I have three select statements made into tables A, B, and C, and that table A has a variable @years, which is a table.
This works when I just run table A by itself, but when I execute the entire query, I get an error about the "declare" keyword, and then some other errors near the word "as" and the ")" character. These are some of those errors that I find pretty meaningless that just mean I've really thrown something off.
So, am I not allowed to declare a variable within these SELECT tables that I'm creating and joining?
Thanks in advance,
Andy

Hi all -
Heres the deal,
I have six tables that are loosly related,
four in one join, two in the other....
in the first join there is a column called commentID -
and is based on a join of the four tables, the results of the
query is based on a where clause
and this needs to be tied into the second set of joined
tables (they are joined on a commentID themselves)
I have both the queries and joins working -
The primary query (4 joined tables) needs to do a lookup on the second (2 joined tables) and add its selected value, into the final result set....
thanks a million for the help!!
take care
tony
I posted Wednesday thinking a SELECT Distinct would solve my problem but it didn't. I have a stored procedure that is used to grab data from 4 tables that I need to join.
The 1st table (Application) holds a job applicant's name and some other data
The 2nd table (Jobs) holds the Job name and test type
The 3rd table (Locations) holds the locations
Then there is a foreign key many to many table (Application_Locations) that holds the applicants UserID and a LocationID. This table may have multiple rows for the same applicant with different locations in each row.
When the procedure is ran I want all the data that I am requesting from the Application table, and all the data that I am requesting from the Jobs table but only the 1st returned result of the Join on the Locations and Application_Locations table. What do I need to do to correct this so that I only display 1 row for each UserID no matter how many locations thay may have applied to. (You will notice that there are some IF statements so only the 2nd and 4th queries in the sproc are the ones that apply )

I am using SQL Server 2005 to publish joined tables for SQL Mobile subscribers for merge replication and column level tracking.
Using Management Studio I am trying to join tables and specify row filters on the joined tables. I.E. table 1 is joined with table 2. I need to define row filters for table 1 and row filters specific to table 2.
An example would be: Table 1 is a customer table that I filter on a specific customer. Table 2 might be an orders table that I need to join to get the customers orders but I also want to filter for open orders only.
When I specify the row filter for table 2 the join appears to be ignored and I receive the complete table 2 with the row filter applied.
I have searched the online books and the web and I have not run accross an example of using both joins and row filters where the filters are specified for both joined tables.
Is this possible via the Management Studio?
Thanks,
Ron
Hello, i have this problem
Table1
tbl1
pcb varchar(30)serial varchar(30)result varchar(30)
tbl2:
pcb varchar(30)date_time varchar(30)result varchar(30) data1 varchar(30)data2 varchar(30),
what i need is query the tbl1 for a range of serials,get the pcb and for those pcb's query the tbl2 for data1,data2
The resultSet should be a join on the two tables, Columns {serial} from tbl1 and {pcb,date_time,data1,data2} from tbl2
Please follow my simple example:
Suppose tbl1 has these 2 records
tbl1 = pcb1,sn1,pass
pcb2,sn2,pass
pcb3,sn3,pass
tbl2= pcb1,date1,pass,dataX1,dataY1
pcb1,date2,pass,dataX2,dataY2
pcb2,date3,pass,dataX3,dataY3
pcb3,date4,pass,dataX4,dataY4
pcb1,date5,pass,dataX5,dataY5
pcb2,date6,pass,dataX6,dataY6
where date1 is the most recent date and date6 the least recent
Request:what i want is for serial>=sn1 and serial<=sn2,get the pcbs from tbl1(which are pcb1 and pcb2) and based on these, query the tbl2
for the other data but retrieve only most recent records.
The correct ResultSet should be
pcb1,sn1,date1,dataX1,dataY1
pcb2,sn2,date3,dataX3,dataY3
and not
pcb1,date1,pass,dataX1,dataY1
pcb1,date2,pass,dataX2,dataY2
pcb1,date5,pass,dataX5,dataY5
pcb2,date3,pass,dataX3,dataY3
pcb2,date6,pass,dataX6,dataY6
What i already did is this:
select max(CONVERT(DATETIME,tbl2.date_time,103)),tbl1.serial,tbl2.pcb
from tbl2
left JOIN tbl1
ON tbl2.Pcb=tbl1.pcb
where tbl1.serial>='1' and tbl1.serial<='53'
and tbl2."Result" like 'pass' and tbl1."result" like 'pass'
group by tbl2.pcb,tbl1.serial;
This works correctly for getting serial from tbl1, date_time and pcb from tbl2.But unfortunately i also need data1 and data2 columns from tbl2.
If i include them in the Select Clause i have to include them also in the group by ,and this gives me also duplicate records (by using this OR philosophy).I mean, it would give all records containing (pcb1,pcb2),much like my example
How can i resolve this issue?
Thank you very much
I'm managing an amature online university and I've been charged with creating a deans list. I have a table for exam results for each course.. currently totaling 5. I have an employeeID column and a total_points column in each table. Sooooo I need to join all the tables and get an average for total_points where the employeeID matches across tables. I have no idea how to write this select.. any help?
View 1 Replies View RelatedI have four tables (all inner joined) and currently they give me the results i need. However, my boss has now asked me to return all associated accounts as well.
I am currently pulling data from the four tables to make up my results table, and the returned results are based on the loan types in my loans tables having a loan type of '1A'
So if the loan type is 1A I get a result.
However, Mr Smith (for example) may have three loans but only one of them is type '1A'. The other two might be type '5H' and '2'.
What I need to be able to do is return all the associated accounts of any customer that has a type '1A' loan.
This is my code:
Select c.customernumber, l.accountsuffix, c.forename, c.surname, lt.code, l.balance, j.journeynumber from customers c
inner join loanagreements l on c.customerid = l.customerid
inner join loantypes lt on l.loantypeid = lt.loantypeid
inner join journeys j on c.journeyid = j.journeyid
Where j.journeynumber = 93
and lt.code = '1a'
and l.balance >0
I get a 90-120 second blocking when send 15 or so simultaneous queriesto SQL Server 2000 that query a view made up of two joined tables.After each query is blocking for the same amount of time they allreturn. Further identical queries of this type work in 3-4 seconds(caching?) until hours later where it happens again. If I query thetables directly (without the view) I still get the same blocking. If Iremove the join (it is a simple inner join on two columns) I do not getthe blocking.Any ideas?
View 3 Replies View RelatedThis seems like a very simple question but i have never been able tofind an easy answer to it.I have a user table and i do a join with another table, we'll call theother table a results table.The results table has numerous rows with the userid foreign key.I want to make a query that will give me the number of rows in theresults table for each user where the result is some valueThe query is simple to make but will only show the users who have arecord in the results table the meet the where criteria, however i wantto display each user and show a record count of 0 when there are noresults in the results table that match the criteria.for example i have 2 tables.tblUsers_______________userid | username--------------------------1 | user12 | user2tblAnswers________________userid | answer----------------------------1 | 11 | 01 | 42 | 12 | 0if i run the query:select max(username), count(answer) from tblUsersleft outer join tblanswers on tblAnswers.userid = tblUSers.idwhere tblAnswers.answer = 4group by tblUsers.idi just getuser1 | 1i want to getuser1 | 1user2 | 0the only way ive found to do this is with a temp table and a curser tocreate all the users records and go back through an insert the answercount for each user. This approach seems very expensive and requires aquery that is 3 times larger than is needed for the same resultswithout including 0 count records. I know there must be a better way todo this.Any help is appreciated.
View 2 Replies View RelatedI have created the following view:
Create view vwOrderItemTotal2
AS
SELECT ItemName, fkMenuItemID, Sum(Quantity) as [SumOfMenuITems] FROM OrderItems GROUP BY fkMenuItemId, ItemName
When I present my data in a GridView, it works fine. For example, several orders for milk are returned as a summary quantity of 26 gallons in a single row of the GridView like this:
26 Milk
Now I need to filter my data by OrderDate and Zipcode. I created this new view:
Create view vwOrderItemTotal5
AS
SELECT Orders.Zipcode, Orders.OrderDate, OrderItems.ItemName, OrderItems.fkMenuItemID, Sum(Quantity) as [SumOfMenuITems]
FROM Orders INNER JOIN OrderItems
ON Orders.OrderID = OrderItems.fkOrderID
GROUP BY fkMenuItemId, ItemName, Zipcode, OrderDate
When I present my data in a Gridview using the new view I get a GridView with multiple rows for milk where each order has its own row like this:
1 Milk
5 Milk
6 Milk
6 Milk
3 Milk
1 Milk
4 Milk
But I want the data presentation in one row for each ItemName (e.g. Milk) as with my first view. Can I adjust my new view to achieve this, or should I stick with my first view (vwOrderItemTotal2) and adjust the Select Command in my SqlDataSource (hasn’t worked yet).
I think that what I want is for the returned data to be grouped by fkMenuItemId only, but the sql server admin won’t let me create a view without including the other fields in the Group By clause. Thanks for any help provided in solving this.
I've read that if particular tables are frequently queried together through a join then these tables should be placed on different devices on different physical disks.
What does this mean exactly and how would you configure this?
Is this a common practice in high-performance real-world environments (or should it be)?
Each row of my datagrid comes from two tables, A and B, which are (left) joined: not every row from table A has a corresponding row in table B. I think this is quite a common scenario.If I want to edit a row in my datagrid which contains data from both Table A and Table B then presumably I can just use an UPDATE statement behind the scenes.But what happens if I want to edit a particular row in the datagrid which contains data from Table A but no corresponding data from table B? I can't use an UPDATE statement because the record in Table B doesn't yet exist. So what do I do?Does anyone know the answer to this, or could you point me to a good tutorial please?

But it should be count the latest result per process only, e.g. for goal "1" just "good" at 03.01.2014. I solved that with a subquery (date=SELECT MAX(...)..).
But now the result "best" disappears, because that column has no date.
Secondly I want to count results for a specific process, e.g. for process4. Every goal has max. one process, with different dates. But one process could have more than one goal.
I want to have this result for process4:
count | result

1 | good
1 | bad
0 | ok
0 | best
But I got only:
count | result

1 | good
1 | bad
I have tried a lot, but nothing works.
The whole result (best, good, ok, bad) are stored in an other table and I joined it.
I have a query which returns all parts and labour lines for a particular work order. It returns all parts lines seperately, but the labour lines are repeated for each row.

For this example what I'd like to see is 5 lines here - the labour description and charge under charges description, unit price, qty and est_parts_sale etc, and of course, there could be more than 1 labour line.

We have an archive table which keeps each instance of a sales order that was archived under a "Verion No" field. Each time the sales order is archived it is entered into the archive tables (Sales Header Archive, Sales Line Archive). What I am trying to do is write a query to return all sales orders but only the most recent archived version.
For example this table layout is similar to what I am working with. Version No, Order No and Customer No. are the keys between the Header and Line tables, Customer Name column in the output is from only the Sales Header Archive table
SALES LINE ARCHIVE TABLE
Version No - Order No. - Customer No -----> (other columns)
1 s-5 1000
2 s-5 1000
1 s-6 2000
1 s-7 3000
2 s-7 3000
3 s-7 3000
1 s-8 4000
1 s-9 2000
2 s-9 2000
Here is what I need to output to show:
RESULTS OF JOINED TABLES
Version No - Order No - Customer No - Customer Name ---> (other columns)
2 s-5 1000 Something, Inc.
1 s-6 2000 Acme
3 s-7 3000 Company, LLC
1 s-8 4000 Blah & Associates
2 s-9 2000 Acme
It should return the last Version No of each Sales order.
Does that make sense? It is something probably easy... But, I've spent two days using multiples and multiples of different ways, that just aren't working: I'm about to dropkick my server cabinet...

I cannot edit table A. I can select records from A and insert into B. And I can select only the records that are in both tables.
But I want to be able to select any records that are in table A but not in Table B.
ie. I want to select records from A where the combination of Product, Tool and Operaton does not appear in Table B, even if all 3 on their own do appear.
This code return all the records from A. I need to filter out the records found in Table B.

We are inserting into a table, which includes an identity primary key column. When the table gets really large (i.e. 1.5 million records), the performance of the inserts reduce.
I noticed that when we insert into the table an exclusive lock on the table is obtained. Do inserts into tables with identities always lock the table?
Given the table size is unavoidable, does anyone have a suggestion to improve the performance?
Thanks,
Matt
I am able to run a query which runs FAst in QA but slow in theapplication.It takes about 16 m in QA but 1000 ms on theApplication.What I wanted to know is why would the query take a longtime in the application when it runs fast on SQL server?How should we try debugging it?Ajay
View 2 Replies View RelatedAfter upgrading to SQL 7 (SP1), we have several SP's that have gone from taking 2-3 min to take 15-20. Each of these SP's creates at least one temp table, inserts into that table, then updates the records in that table. From our research, we can tell that the creation and inserts into the temp tables are fine. It is the updating of these tables that causes the problem. We can observe that the problem is happening by watching the processors go to and stay above 90%. If it were just a few SP's, we could easily fix it and go on, but because of 6.5's limit of 16 tables referenced in a SP, we had to use this method many times. Is there a fix out there for this or a configuration change I can make?
View 2 Replies View RelatedHi,
I currently have a large table (35 million rows, over 80GB). I have one varchar(max) column on the table that is used in the fulltext index.
To query the complete index is fast, for example:
SELECT 'ipod', COUNT(*)
FROM CONTAINSTABLE(MyDB.dbo.Contents, [Body], 'ipod') CT
This took 70 seconds (which I can live with). However, I seldom run queries like this, most are more like:
SELECT 'ipod', COUNT(*)
FROM CONTAINSTABLE(MyDB.dbo.Contents, [Body], 'ipod') CT
JOIN Pages ITP ON ITP.PageID = CT.[Key]
JOIN Feeds ITF ON ITP.IPID = ITF.IPID
JOIN Buyers ITB ON ITB.IBID = ITF.IBID
WHERE ITB.ID IN (1342,246)
These queries are much slower (this example took 17 minutes). I understand that FT searches the index and returns all rows that match the query to SQL. SQL then performs the joins and counts only the correct results. (Correct me if I'm wrong here).
One solution I've seen to this to put data or "tags" into the FT column - so my Body column would become something like:
'{ID:1342}' + [Body]
That sounds like a very good idea. I could then change the 2nd query above to be:
SELECT 'ipod', COUNT(*)
FROM CONTAINSTABLE(MyDB.dbo.Contents, [Body], '("ID:1342" OR "ID:246") AND "ipod"') CT
That all works well until I want to select 1000 different ID's because the FT query will become very long and complex. Also I'm only including one column (ID) in this example - but I have about 7 or 8 columns that I would need to include in these "tags". Quering multiple columns become very complex quickly and no doubt I will reach a query limit at somepoint.
If anyone has any other suggestions to the above I'd love to hear them. Another thought I'm having is to partition the table. I can find very little online about how FT behaves on partitioned tables - I fear it behaves exactly the same, what I'd like to think is that I could partition the table on an ID say 100 per partition or something, and then fulltext would only search the relevant partitions. If it behaves like this it may work. If no-one knows then I'll give it ago, but this will take me a while due to the table size - so I'm hoping one of you clever lot know!
Many thanks for any advice.

Hi,I have a table with about 70k rows. When I use open table --> returnall rows and then edit a field Enterprise Manager then says it has toreturn the entire result set for the update to take place.This can take a long time and makes editing data a slow process. Isthere any way to get Enterprise Manager just to update the one row??Thanks Tom
View 1 Replies View RelatedI try to convert a Procedure that join 8 tables with INNER AND OUTER JOIN, my understanding is that the Lookup task is the one to use and I should break these joins into smaller block, it takes a long time to load when I do this, since each of these tables had 10-40mill. rows and I have 8 tables to go thru, currently this Stored Procedure took 3-4min to run, by converting this to 8 Lookup tasks, it ran for 20min. has anyone run into this issue before and know a work around for this.
Thanks
I am using two almost idential laptops, one with XP and one with Vista, the only differences is that the XP laptop has 1G of RAM and running Office XP and the Vista has 2G RAM and is running Office 2007.
I have a MS Access database that has linked tables to a SQL Server 2000 database. The performance of the Access database on Vista is 5-10 times slower on the Vista machine. Just flipping through records or opening forms can take 5 - 15 seconds on the Vista machine while the XP machine takes 1 sec or less.
What gives? I looked at the CPU performance and the network performance while the Access database was busy flipping through records, the network traffic was < 2% and the CPU would spike to 40% on one of the CPUs (dual core) but would remain under 5% most of the time.
I also previously had Office XP installed on the Vista machine and it had the same performance issue so bought and install Office 2007 on the Vista machine and it did not solve the problem.
It seems that Vista is doing something that is slowing down Access with linked tables. Is this a issue between Vista and using an ODBC connection to SQL Server?
Thanks in advance for any help on this
I have an update query running which to just now has been running for 22 hours running on two tables 1 a lookuptable that has just been created within the batch the other a denormalised table for doing data analysis on
the query thats causing teh problem is
--//////////////////////////////////// this is the one thats running
Print 'Update Provider 04-05 EmAdmsCount12mths : ' + CAST(GETDATE() AS varchar)
GO
Update Provider_APC_2004_05
set EmAdmsCount12mths =
(Select COUNT(*)-1
from Combined_Admissions
where ((Combined_Admissions.NHSNumber = Provider_APC_2004_05.NHSNumber) or
(Combined_Admissions.PASNUMBER = Provider_APC_2004_05.PDDISTNO)) and
(Combined_Admissions.AdmDate BETWEEN DateAdd(yyyy,-1,Provider_APC_2004_05.AdmDate) AND Provider_APC_2004_05.AdmDate) AND
Combined_Admissions.AdmMethod like 'Emergency%')-- and
-- CA.NHSorPrivate = 'NHS'))
FROM Provider_APC_2004_05, Combined_Admissions
any help in improving speed would be most welcome as there are 3 more of these updates to run right after this one and the analysis tables are almost double the size of this one

Hi there
Running query analyzer against two different server.
the first only need 1-2 secs to return the query result,
the other return 7-8 secs for the query result.
plz advice what could cause this slow performance?
thx
