hello gang, Is it possible to combine sql update statements? something like:
UPDATE table_name
SET column_name = new_value
WHERE column_name = some_value
AND
SET column_name = new_value
WHERE column_name = some_other_value
Hi guys! Is there a way to combine these update statements?
Dim update_phase As New SqlCommand("INSERT INTO TE_shounin_zangyou (syain_No,date_kyou,time_kyou) SELECT syain_No,date_kyou,time_kyou FROM TE_zangyou WHERE [syain_No] = @syain_No", cnn)
Dim update_phase2 As New SqlCommand(" UPDATE TE_shounin_zangyou SET " & " phase=2, phase_states2=06,syounin2_sysd=CONVERT(VARCHAR(10),GETDATE(),101) WHERE [syain_No] = @syain_No", cnn)
The same table is updated so I think it would be better to have just one update statement. But the problem is that, the first update statement retrieves values from another table, whereas the update values of the second statement is fixed. Is there a way to combine these two statements. I tried to do so but it does not update. Here's my code...
Dim update_phase As New SqlCommand("UPDATE TE_shounin_zangyou SET TE_shounin_zangyou.syain_No=TE_zangyou.syain_No, TE_shounin_zangyou.date_kyou=TE_zangyou.date_kyou, TE_shounin_zangyou.time_kyou=TE_zangyou.time_kyou FROM TE_zangyou WHERE TE_zangyou.syain_No = TE_shounin_zangyou.syain_No", cnn)
Please help me. Thanks.

How can i put these two statements into a single sql statement.
Thanks.
I have the following 3 SQL statements that need to be combined, ifpossible. The output of one feeds the input of the next. I need to viewall of the defined output fields (the output needs to be used in aCrystal Report).The SQL Follows:/* Input is ISBN (vendor_part_number) */QUERY_1 - returns 1 recordselect p.product_id, v.name, m.description, p.author, p.title,p.revision_number, p.copyright_edition, p.vendor_part_number,p.conforming_flag,m.code, mp.unit_price_product, mm.quota_pricefrom T_PRODUCT p, T_VENDOR v, T_PRODUCT_VENDOR pv,T_MULTILIST_PRODUCT mp, T_MULTILIST m,T_MULTILIST_MEMBERSHIP mm where/* p.vendor_part_number == input */p.vendor_part_number = '0153364475' and p.medium_type ='TEXTBOOK' andp.product_id = pv.product_id and pv.type = 'CONTRACT' andpv.vendor_id = v.id andp.product_id = mp.product_id andm.code = mp.multilist_code and m.proclamation_year =mp.proclamation_yearand m.proclamation_seq_id = mp.proclamation_seq_id andm.code = mm.multilist_code and m.proclamation_year =mm.proclamation_yearand m.proclamation_seq_id = mm.proclamation_seq_id/* The above should return a single record */QUERY_2 - returns 2 recordsselect p.product_id, p.consumable, p.title, p.copyright_edition,p.vendor_part_number, p.product_type,p.item_type, p.hardware_requiredfrom T_PRODUCT p, T_PRODUCT_RELATION pr where (pr.relationship_type ='AID'or pr.relationship_type = 'KIT') andp.product_id = pr.child_product_id and pr.parent_product_id =90321/* 90321 = result from above: pr.parent_product_id = p.product_id*/QUERY_3 - returns 18 recordsselect p.product_id, p.consumable, p.title, p.copyright_edition,p.vendor_part_number, p.product_type,p.item_type, p.hardware_requiredfrom T_PRODUCT p, T_PRODUCT_RELATION pr where (pr.relationship_type ='AID'or pr.relationship_type = 'KIT') andp.product_id = pr.child_product_id and pr.parent_product_id in(90322, 90323)/* 90322, 90323 = result from QUERY_2: pr.parent_product_id =p.product_id */Only 21 records are returned from these combined queries. I need accessto all of them even though there are 3 different resultsets, 2 of whichcontain the same fields. Is there a way to simplify this into a storedprocedure or a view that can take 1 input parameter? It needs to beused in a Crystal Report, which is limited in its handling of thesetypes of complex queries.
View 1 Replies View RelatedI am not sure if this is possible, but I was wondering if I can combine 2 SELECT statements so as to aquire a percentage..
I could be overthinking this....I am fairly new to SQL writing.
Here is an example of the 2 SELECT statements that I am using:
Code:
SELECT COUNT([Overall Rating]) FROM S526960.HDPIMaster WHERE Location = 'HBUS' AND [Overall Rating] = 'Good'
Code:
SELECT COUNT([Overall Rating]) FROM S526960.HDPIMaster WHERE Location = 'HBUS'
Within my output I am than taking the the data from the 1st query and dividing it by the 2nd query to get a percentage.
I was hoping that I could accomplish the same action within one SQL statement.
Thank you for your consideration!
I have two SQL queries that I would like to combine. Each query is dependent on the same table, and the same rows, but they each have their own WHERE statements. I've thought about using some JOIN statements (left outer join in particular) but then I run into the problem of not having two separate tables, and don't see where I can put in two separate WHERE statements into the final query. I've read into aliasing tables, but I'm not quite sure how that works (how to put it into code or a JOIN statement) , or if it would solve my question. Do you have any ideas or examples of how to solve this scenario?

I have a database that tracks billing and payment history records against a "relationship" record (the "relationship" maps a many-to-many relationship between employees and cell phone numbers).
I have two statements that look like this:
SELECT CellPhone.PhoneNumber, SUM(BillingHistory.AmountOwed) AS TotalOwed
FROM Relationship
INNER JOIN CellPhone ON CellPhone.PKCellPhone = Relationship.FKCellPhone
INNER JOIN BillingHistory ON Relationship.PKRelationship = BillingHistory.FKRelationship

CellPhone.PhoneNumber, SUM(BillingHistory.AmountOwed) AS TotalOwed, SUM(PaymentHistory.AmountPaid) AS TotalPaid

I have 2 SQL server 2000 machines, I need to take a table from each one and combine them together based on a date time stamp. The first machine has a database that records information based on an event it is given a timestamp the value of variable is stored and a few other fields are stored in Table A. The second machine Table B has test data entered in a lab scenario. This is a manufacturing facility so the Table A data is recorded by means of a third party software. Whenever a sample is taken in the plant the event for Table A is triggered and recorded in the table. The test data may be entered on that sample in Table B several hours later the lab technician records the time that the sample was taken in Table B but it is not exact to match with the timestamp in Table A. I need to combine each of these tables into a new SQL server 2005 database on a new machine. After combining the tables which I am assuming I can based on a query that looks at the timestamp on both Tables A & B and match the rows up based on the closest timestamp. I need to continuously update these tables with the new data as it comes in. I havent worked with SQL for a couple of years and have looked at several ways to complete this task but havent had much luck. I have researched linked servers, SSIS, etc Any help would be greatly appreciated.

View 1 Replies View RelatedHello,
I am creating my companys' database and I have a small problem that must be
solved.
I have a pictures table:
PicturesTable
-------------
ProductID int ForeignKey
Picture nvarchar(30)
...
(A product can have many pictures & the ProductID is unique for any product,
but not for the table of pictures).
What I want to do is to somehow do a procedure to:
1) Check if any images (for a productID) exists in the table
2) if they do not exist then add the appropriate images into the table
3) if the images exist, then update the images with the new one that I have.
What I thought was to just delete all the images from the table for the
specific product:
DELETE FROM PicturesTable
WHERE ProductID = '10-11'
and then add the appropriate images:
INSERT INTO PicturesTable (ProductID, Picture)
VALUES ('10-11', 'Dir1/Pic1.gif')
INSERT INTO PicturesTable (ProductID, Picture)
VALUES ('10-11', 'Dir1/Pic2.gif')
INSERT INTO PicturesTable (ProductID, Picture)
VALUES ('10-11', 'Dir1/Pic3.gif')
but I do not like a lot this idea because if a user tries to read the pictures
for that product (at the same time I was deleting them) s/he would get
nothing. Is any other way that I can do it please?
I would appreciate it if someone answers me.
Yours, sincerely

My manager is interested in knowing if there is a way to update our website's SQL database using a method with excel, similar to importing.
The person who was previously in my position had imported a few hundred new products into the database with an excel spreadsheet.
Now, we would like to make updates such as a price changes or similar adjustments to a number of the products in the database. We could use a web interface, but ours requires us to find each product individually and it takes too much time. I told him that it would probably be necessary to write an SQL statement to update the tables, but we're also interested in maintaining the integrity of the database and are worried about loosing data due to a typo. Is it possible to export the db contents to an excel file, make changes, and then merge those changes into the existing database? I have tried and failed, so I am wondering if any experienced users could help me out.
Also, is there some kind of phpmyadmin for MS SQL? A free, open source alternative would be best.

What is the single SQL statement to truncate the blank space on either side of data.
Ex.
Table1 has Name as column.
I have records filled with blank space on both side for Name field.
With one query I want to correct (truncate the leading and trailing space) the data.
How?

I am almost sure I can update variables columns in one select/case type
statement, but having problems working out the syntax.
I have a table with transactions - with tran types as the key.
in this example, types = A,B,C ,D.
in this first example I am updating the sum of QTY to value t_A based on
tran types =A.
can I perform sub query/case to update with the same where clause
but for types B,C and D?? I also have to insert for specific lot numbers each sum values.
Create table #t_reconcile(
t_lot_number int not null,
t_A float,
t_B float,
t_C float,
t_D float)
insert #t_reconcile
select t.lot_number, sum(t.qty)
from i , t
where i._id = t.event_id
i.transaction_type = 'A'
group by t.lot_number
order by t.lot_number
I'm working on a query which involves changing the case of a field from mixed case to all lower case. The field exists in multiple tables, so to do this I have multiple update statements. Is there a way to make this more efficient?
See below for example:

set BrokerID = lower(BrokerID)
update InvestFill
set BrokerID = lower(BrokerID)
update InvestBrokerAccount
set BrokerID = lower(BrokerID)
update InvestFIXBroker
set BrokerID = lower(BrokerID)
update InvestUploadBrokerFilter
set BrokerID = lower(BrokerID)
update InvestSettleInstructions
set BrokerID = lower(BrokerID)
I get the error:
(0 row(s) affected)
Msg 208, Level 16, State 1, Line 41
Invalid object name 'X_SET_PREOP'.
FOR THE FOLLOWING CODE SEGMENT.. I am trying to do 2 updates with just one WITH BLOCk.Create table #temp( MPOG_CASE_ID uniqueidentifier, lab_name varchar(100), lab_date datetime, lab_value decimal(19,2) );

View 3 Replies View RelatedOur existing DW's ETL was written in a very complex fashion by the previous team. They use DTS package lookups to read a row in the Source SQL Server database see if that row exists in the taget SQL Server database. If the row does not exist, they use ActiveX scripts to INSERT the row in the target SQL Server database. If it exists, they update the row on the target side. How would you do this in SSIS? Apologize if this sounds like a basic question, however, I would have done this via Stored Procedures or SQL Scripts especially since it involves SQL Servers alone. Appreciate any help.

I have been posting to the Data Presentation Controls forum for about a month regarding a problem I've been dealing with.
http://forums.asp.net/thread/1223055.aspx
What it boils down to is that on a button click event, I was updating
some records, then re-executing a SELECT statement to get the records
back out and rebind my DataGrids. This was happening too quickly
and the data was not being updated in time before the SELECT was
executed. So my grids would still display "old" data.
How do I get SQL Server to commit the UPDATE before my C# code continues?
Hi all,
Does an UPDATE statment lock the entire table or just the rows that will be affected by the UPDATE?
I ask because -
Can I run UPDATE statements in parallel on the same table on the same column. The need for doing this is because the table is a large fact table. I plan to execute the same UPDATE statements on different time sections of the data to expedite the processing.
If the UPDATE statment lock the entire table then I cannot run an UPDATE in parallel. If the UPDATE statement just locks the rows that will be affected then maybe I can because rows affected will be different for each UPDATE.
Let me know.
Thanks,
Vivek
When working from within VB, should i be using Insert or Update statements, or should i pass the values to a stored proc that does it for me.

I searched a bit but didn€™t get too far in actually solving a case of deadlock in a simple query I have running here. The queries in question are executed under 2 separate transactions (Serializable IsolationLevel) and are shown below. I guess I don€™t understand how those 2 can deadlock because they are operating on different rows of the table and Serializable should keep them isolated pretty well too. Is it because I€™m using the column value inside an update stmt? How should this query be split if that€™s the case?
This is what the SQL Profiler has to say:
Lock: Deadlock Chain Deadlock Chain SPID = 59
Lock: Deadlock Chain Deadlock Chain SPID = 57
Lock: Deadlock my_user_name
57: UPDATE CreditCard SET Balance = Balance - 200 WHERE (Account = 0 AND CardHolder = 'Foo' AND Balance - 200 >= 0)
59: UPDATE CreditCard SET Balance = Balance - 250 WHERE (Account = 3 AND CardHolder = 'Bar' AND Balance - 250 >= 0)
I also used DBCC TRACEON(1204, 3605, -1) but I don€™t understand what the SQL log is telling me. Can anyone shed some light on why the above 2 statements sometimes cause the following:
System.Data.SqlClient.SqlException: Transaction (Process ID 57) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.

Hi , I am trying to update a main table from its staging table based on certain criteria
like if the checksum doesnot match for the same Business/primary key update that row in the main table .
problem what i am facing is if there are two rows in the staging table with different checksum values the main table's corresponding row gets updated with only the first row from the staging table and ignores the second row in staging , i want the update to be capturing each row. is there a way to do this task repitively in ssis.
iam using execute sql task in ssis
first step to delete all matching checksum records in staging
next update non matching checksum into main table.
i want to repeat these two steps based until condition that count of rows in staging is equal to zero .
is there a way to acheive this please let me know.
for example
staging main table
name age checksum name age checksum
xyz 26 456 xyz 24 876
xyz 28 234
my result should have in main table
xyz 28 234
but instead i am getting xyz 26 456
i want the update statement row by row not set based . please help me with this
Hi, I just want you to know that I am very young in ASP.NET world so please bear with me.I have been looking for an answer to my problem, but unfortunately I couldn’t find one. So I created a user here on www.asp.net just for making this post.
Before I continue I just want to apologies if there is another post where this question is already answered.
Please watch this Print Screen I just took: � http://www.bewarmaronsi.com/Capture.JPG “
As you can see the “INSERT, UPDATE, and DELETE Statements� are disabled, and that’s exactly my problem. I tried with an MS access database and it works perfect, but when I use a MS SQL database this field gets disabled for some reason.
The MDF file is located in the App_data folder and is called ASPNETDB.
And when I try to add custom SQL statements, it gives me Syntax error near “=�. Something like that. I bought the Total Training Set1 package and it works perfect in their examples.
I just want to thank you for reading my post and I hope that you got some useful information for me.
By the way, I’, from Sweden so you have to excuse me if my English is rusty.
Thanks!

Auditors want us to track when Insert, Update and Delete failures occur. Is this possible in SQL 2000?
They also want us to track schema changes. Is this possible?

I have a main table called Stock for example.
One process ( a service ) inserts data into this table , as well as updates certain fields of the table periodically.
Another process ( SQL Job ) updates the table with certain defaults and rules that are unknown to the service - to deal with some calculations and removal of null values where we can estimate the values etc.
These 2 processes have started to deadlock each other horribly.
The SQL Job calls one stored procedure that has around 10 statements in it. This stored proc runs every minute. Most of them are of the form below - the idea being that once this has corrected the data - the update will not affect these rows again. I guess there are read locks on the selecting part of this query - but usually it updates 0 rows - so I am wondering if there are still locks taken ?
UPDATE s
SET equivQty = Qty * ISNULL(p.Factor,4.5) / 4.5
FROM Stock s
LEFT OUTER JOIN Pack p
on s.Product = p.ProductId
AND s.Pack = p.PackId
WHERE ISNULL(equivQty,0) <> Qty * ISNULL(p.Factor,4.5) / 4.5
The deadlocks are always between these statements from the stored procedure - and the service updating rows. I can't really see how the deadlocks occur but they do.
Another suggestion has been to try and use an exists before the update as below
IF EXISTS( SELECT based on above criteria )
( UPDATE as before )
Does this reduce the locking at all ? I don't know how to test the theory - i added this code to some of the statements, and it didn't seem to make much difference ?
Is there a way to make a process ( in my case the stored procedure ) - give up if it can't aquire the locks rather than being deadlocked - which leads to job failures and emails etc ?
We are currently trying to filter down the data that is updated to be only the last few months - to reduce the amount of rows even analyzed - as the deadlocking does seem to be impacted by the number of rows in the tables.
