Update Query When Joined Tables Are Involved

Sep 30, 2013

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')

How To Update A Row Based On Left-joined Tables?

May 12, 2008

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?

T-SQL (SS2K8) :: Update A Field In 3rd Table From 2 Joined Tables

Jul 29, 2015

I have a script that is supposed to run thru 2 joined tables and update a field in the 3rd table. The script works but takes approx. 4 hours to run against 250k records.

UPDATE a
SET Con_Mailings = STUFF((SELECT '; ' + c.ListName
FROM [server].[xxxxx_MSCRM].[dbo].ListBase c with (nowait)
INNER JOIN [server].[xxxxxx_MSCRM].[dbo].[ListMemberBase] b with (nowait)
ON b.ListID = c.ListID
WHERE b.EntityID = a.TmpContactID
FOR XML PATH('')),1,1,'')
FROM [xx_Temp].[dbo].[Lyris_CombinedTest] a

I should end up with something like this in the con_mailings field:

'Mailing1, Mailing2, Mailing3'

Slow Query On Joined Tables

Sep 12, 2006

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
B

Better Method Than Joined Query Tables

Nov 27, 2007

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

SQL2000: Disable Trigger Not Allowed In Tables That Involved In Publication.

Apr 10, 2007

We have setup a replication in SQL2000:

We have DTS package automatically pouring data into the publishing database(source tables). During this process, we want to temporary disable certain triggers. However, the command

Alter table 'tbl' disable trigger 'abc' errored out. The error message said:

''Cannot alter the table 'tbl' because it is being published for replication."

I've digged more into this and found although it's not allowed to disable a triggers,

the SQLServer do allow delete the trigger and recreate them.

Is there any way to disable the trigger directly?

Thanks in advance,

Don



BTW:

I've used the following sql directly, however the trigger still fires.

UPDATE
sysobjects
SET
status = status|2048
WHERE
type = 'TR'
AND
parent_obj = OBJECT_ID (@table_name)



The only other way around now is to create stored procedures that dynamically create the trigger. Because our trigger is normmally larger than 8000 bytes. We have to create one stored procedure per trigger. This option is not acceptable because not only it takes quite a time, but also a maintainance nightmare.

Declaring A Table Variable Within A Select Table Joined To Other Select Tables In Query

Oct 15, 2007

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



Select * from

(

declare @years table (years int);

insert into @years

select

WHEN month(getdate()) in (1) THEN year(getdate())-1

Set-based Update - Table Joined On Itself

Dec 15, 2005

Guys - sorry for the long post - hope it's clear

DDL/DML below

I want to update the startdate column (for all rows) so that when period is 0 then the new value
is a hardcoded value (say '01-Dec-2000') but for all other rows it takes the value in the
enddate column for the row of the previous column (with the same freq)

ie the startdate column for period 1 takes the enddate value for period 0 and so on for a particular freq

create table #periods (period int , startdate datetime , [enddate] datetime , freq int)
insert #periods ( period , startdate , enddate , freq)
select 0 , '01-Jan-1900' , '31-Jan-2001' , 1
union all
select 1 , '01-Jan-1900' , '28-Feb-2001' , 1
union all
select 2 , '01-Jan-1900' , '31-Mar-2001' , 1
union all
select 3 , '01-Jan-1900' , '30-Apr-2001' , 1
union all
select 4 , '01-Jan-1900' , '31-May-2001' , 1
union all
select 0 , '01-Jan-1900' , '31-Jan-2002' , 3
union all
select 1 , '01-Jan-1900' , '28-Feb-2002' , 3

union all
select 4 , '01-Jan-1900' , '31-May-2002' , 3

I know I need a case statement to test for column 0 and to join the table on itself and have put something together

PA1.Startdate =

Joining Two Joined Tables

May 15, 2002

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

Problem With Joined Tables

Feb 1, 2008

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 )

Here is the SPROC that is currently in place but is displaying a row for each location.

How To Specify A Row Filter On Joined Tables

Dec 7, 2006

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

Get Most Recent Data From Joined Tables??

Apr 25, 2008

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

Four Tables Inner Joined - Select Associated Accounts

Feb 14, 2014

I 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

Help With Blocking On Querying Two Joined Tables

Dec 8, 2005

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?

Querying Joined Tables With 0 Results

Jan 18, 2006

This 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.

UPDATE Into JOINed Table - Access Vs. SQL Server Syntax

Sep 13, 2007

I am trying to get a SQL statement to work with both Access 2000 and SQL Server 2000.

The statement that works in SQL Server is:

---
UPDATE [myTable2]

SET
[myTable2].[FieldA] = 'Hello',
[myTable2].[FieldB] = 2,
[myTable2].[FieldC] = 'xxx',
[myTable2].[FieldD] = 0

FROM [myTable1] INNER JOIN
(myTable2 INNER JOIN [myTable3]
ON [myTable2].[FieldX]=[myTable2].[FieldY])
ON [myTable1].[FieldZ]=[myTable2].[FieldY]

WHERE ([myTable2].[FieldY]=1)
And ([myTable3].[FieldZ]='xxx');
---


(names have been changed to protect the innocent)


The statement that works in Access is:

---
UPDATE [myTable1] INNER JOIN
(myTable2 INNER JOIN [myTable3]
ON [myTable2].[FieldX]=[myTable2].[FieldY])
ON [myTable1].[FieldZ]=[myTable2].[FieldY]

SET
[myTable2].[FieldA] = 'Hello',
[myTable2].[FieldB] = 2,
[myTable2].[FieldC] = 'xxx',
[myTable2].[FieldD] = 0

WHERE ([myTable2].[FieldY]=1)
And ([myTable3].[FieldZ]='xxx');
---


It seems that neither will accept the other format. Can anyone suggest how I can rearrange the statement so that it works in both?

View With Aggregate Function And Joined Tables

Mar 2, 2007

I 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.

Placing Joined Tables On Separate Disks

Apr 7, 2008

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)?

Joined Tables - Count And Null Values

Jan 11, 2014

I joined different tables and got a result like this:

result | process | goal | date |
------- ---------- ------ -----------
ok | process4 | 1 | 12.10.2013
bad | process1 | 2 | 13.10.2013
ok | process1 | 4 | 12.12.2013
good | process4 | 1 | 03.01.2014
ok | process1 | 3 | 10.04.2013
bad | process3 | 6 | 09.01.2014
bad | process4 | 3 | 30.12.2013
best |NULL| NULL

Now I want to count the results by counting the processes and group them by the result.

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.

Select Rows Separately From Two Joined Tables

Nov 5, 2014

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. What I want to accomplish for a given work order, is a list of all the parts lines, followed underneath by a list of all labour lines.This is the code from the report:

select
h.worknumber,
--- Select parts lines and charges
wp.description as [charges desc],
case
when wp.charge_to_cust = 1 then wp.sale_price

[code]...

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.

IIF Statment To Compare Two Values In Joined Tables

May 3, 2007



Hi



I'm trying to compare two varchars to check if they are the same, if they are the same then the color must turn red, if not then they must remain black



SELECT *

from members m, client c

where C.ClientID = m.ClientID

AND c.ClientID in (87,86)

AND m.email in ('dassd@fdskjh.com','asdfas@sdfd.net', etc...)



my results will give me two of the same email addresses but with different ClientID's, now when it

finds the same email it needs to make them both "RED"



Please help, any advice would be helpful



Kind Regards

SQL 2012 :: Parallel Query Worker Thread Was Involved In A Deadlock

Oct 22, 2015

I have a deadlock trace running on a production server that is filling up with the following:

Lock: Deadlock Chain
Parallel query worker thread was involved in a deadlock SPID 8
105 - Resource Type Exchange

Spid 8 is a SQL process LOCK MONITOR

There are no graphs as seen with typical deadlock, so it is not two queries that are deadlocking, and I've never seen a deadlock for "LOCK MONITOR"
