Transact SQL :: Undo Update And Bring Back Records To Their Previous Values
Aug 7, 2015
I have a table with 1 million records. I want to update only 400 records. The update statement is provided by a 3rd party vendor. Once i run the update statement it will update all the 400 records. Once the table is updated the users will validate the table
if the update is successful or not. What i'm looking for is:
1) Is there a way to identify what records were updated.
2) If the update done is not what the users wanted i need to undo and bring back the 400 records to their previous values.
12.) Now you have two different tables - each with two columns.Table #1Single Column2 rows with a value equal to 1 and 2Table #2Single column2 rows with a value equal to 2 and 4Construct a statement returning in a single column all the valuescontained, but not the common values.This is another question that I got in an interview, I missedit.......Thanks,Tim
I have a scenario to compare previous records based on each ID columns. For each ID, there would be few records, I have a column called "compare", We have to compare all Compare 1 records with Compare 0 Records. If Dt is lesser or equal to comparing DT, then show 0. Else 1
We always only one Compare 0 records in my table, so all compare 1 columns will compare with only one row per ID
My tables look like
Declare @tab1 table (ID Varchar(3), Dt Date, Compare Int) Insert Into @tab1 values ('101','2015-07-01',0) Insert Into @tab1 values ('101','2015-07-02',1) Insert Into @tab1 values ('101','2015-07-03',1) Insert Into @tab1 values ('101','2015-07-01',1) Insert Into @tab1 values ('101','2015-06-30',1)
Insert Into @tab1 values ('102','2015-07-01',0) Insert Into @tab1 values ('102','2015-07-02',1) Insert Into @tab1 values ('102','2015-07-01',1)
select * from @tab1
1.) In the above scenario for ID = '101', we have 5 records, first record has Compare value 0, which mean all other 4 records need to compare with this record only
2.) If Compare 1 record's Dt is less or equal to Compare 0's DT, then show 0 in next columnÂ
3.)Â If Compare 1 record's Dt is greater than Compare 0's DT, then show 1 in next columnÂ
I am looking to pull all records for current & previous calendar year in one query. I know how to pull the current calendar year, but how would I pull current & previous?
I'm trying to insert records into "holding" table and write back identity column value (Entry_Key) to the original table. So my setup is I have two tables; tblEWPBulk and tbleFormsUploadEWP. Users will enter records into tblEWPBulk and use BatchID to group records, once batch entry has been completed (usually less than 30 records) user will click on UploadAll button and insert records (not all fields) into tbleFormsUploadEWP. One record in tblEWPBulk can be sent multiple times to the holding table but tblEWPBulk will need to have latest Entry_Key captured. Records are sent from holding table to DB2 z/VSE using SQL stored procedure and based on certain logic records are marked uploaded or certain error capture... that part works fine.
So for example I want to sendÂ
BatchID, AccountNumber, Period, ReceiveDate, AccountType, ReturnType, NetProfitOrLoss, TaxCredit FROM tblEWPBulk to the holding table and write back Entry_Key (identity column) back to the record in tblEWPBulk (field called UploadEntryKey). As I said one record could be sent to the holding table multiple times until uploaded or deleted and UploadEntryKey always needs to be updated so that when results are processed response from the DB2 can be inserted into table and presented to the user.
No foreign key relationship exists since records in the holding table get sent to the archive table and table is truncated and entry_key starting value reset back to 2000... just some DB2 restrictions.Â
Hi all,I have been wrestling with this problem all morning with no success sofar where I have a need to bring back an excluded field.Basically I have a list of order numbers. Each order number can havemany order types attached one of which is a ‘P’ type. Most order typeshave an account number attached in its own field however when a ‘P’ typeis selected the account number is not brought back.Is there someway I can get this brought back for each P type or do Ihave to do some fancy insert in a data warehouse to get this done (i.e.insert account numbers into all P types)?Many thanksSam*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
I am trying to do a calculation with the below query and it works long as d.closegoal has values and d1.opengoal has values but the problem is when there is no count for either, I need to bring back a value of zero if there are no matches. Since I am using it in an outer select statement for a calculation it not bringing anything back because of no matches. This is my code:
select d.lwia,
cast((d.closegoal + d1.opengoal) as float)denominator
from
(
select yg.lwia,
cast(count(yg.appid)as float) closegoal
from dbo.wiayouthgoals yg
where yg.lwia = @RWB
-- Attained a goal in the timeframe timely or untimely
and ((convert(smalldatetime, convert(varchar(10),yg.youthattaindate, 101)) >= @BeginDte -- Parm date for beginning of time frame needed
and convert(smalldatetime, convert(varchar(10),yg.youthattaindate, 101)) <= @EndDte) -- Parm date for end of time frame needed
-- Goal due but not attained
or (convert(smalldatetime, convert(varchar(10),yg.youthgoalanniversary, 101)) >= @BeginDte -- Parm date for beginning of time frame needed
and convert(smalldatetime, convert(varchar(10),yg.youthgoalanniversary, 101)) <= @EndDte -- Parm date for end of time frame needed
and yg.youthattaingoal <> 1))
group by yg.lwia
)d,
(
-- Closure with open goal
select cast(count(yg.appid)as float) opengoal
from dbo.tbl_caseclosure cc,
dbo.wiayouthgoals yg
where yg.appid = cc.col_idnum
and convert(smalldatetime, convert(varchar(10),cc.col_closuredate, 101)) >= @BeginDte -- Parm date for beginning of time frame needed
and convert(smalldatetime, convert(varchar(10),cc.col_closuredate, 101)) <= @EndDte -- Parm date for end of time frame needed
I'm trying to recreate a sql database on another server and I installed sql server 6.5 on a server and then restored the master db using the Sql Setup program. It worked without any errors, but it did not create the loginthat will use the database that I have not restored yet. Aren't the Logins storied in the master database?
I have a column that has 75 values, 50 are unique/25 are duplicates. Ineed to be able to bring back a list of the duplicates, listing allrows even if more than two have the same value. I need to be able todo this using t-sql.Thanks,Tim
I'm wondering if somebody could provide insight into a problem I'm having with SQL Server 2005. Although the problem is happening wthin an SSIS ETL, I don't think this problem is SSIS related.
In the ETL I need to rename a database, so I first put the database into single-user mode by issuing the command:
ALTER DATABASE foobar SET SINGLE_USER WITH ROLLBACK 30
The database then goes into single-user mode, and after the renaming occurs, I attempt to put the same database back into multi-user mode:
ALTER DATABASE foobar SET MULTI_USER WITH ROLLBACK IMMEDIATE
However, whenever I have a query pane opened against the same database in SQL Server Management Studio, the ETL fails and I get this error message:
"Error: Changes to the state or options of database 'foobar' cannot be made at this time. The database is in single-user mode, and a user is currently connected to it."
I'm wondering why the ALTER DATABASE command does not kill off the active connections? This is on my development box, and I'm the only one connected to the database. I've tried with ROLLBACK 30 as well, same thing. If I cut and paste the same command into Mangement Studio, the command succeeds so I don't think its a permission issue (using Windows Authentication both Management Studio and the ETL are executed by the same login). If I close the query pane the ETL succeeds at restoring multi-user mode. Is there something I am missing? Thanks in advance!
I have the membership stuff up and running. I've added a field to the membership table called custnmbr. Once a user logs in, I want store his custnbmr in the session and use that to lookup data in another db. ie: Joe logs in and his custnumbr is 001, he goes to the login success page and sees his list of service calls which is: select top 10 * from svc00200 where custnmbr = 001 (the membership.custnmbr for the logged in user) I know how to do this in old ASP using session variables....but I have no idea where to even start with .Net. Many thanks
I have update a table field and I like to know how do you "undo" the update? I set the field_length from 6 to 7 and like to undo this.Here is my command:
table = template_fileds column= field_length. filed name= field_name. update template_fields set field_length='7' where field_name='assesscode9'
I am trying to update a row, which is being pulled from another table.
i.e., I have two tables T1 and T2
I am getting a row from T2 and inserting it in T1 then I am updating that row in T1
What i want is if in case these is an error while updating this row I want to remove the row from T1 T1 and T2 are same.
declare @err1 int
--BEGIN TRANSACTION
INSERT INTO dbo.T1 SELECT * FROM dbo.T2 WHERE UpdateFlag = 'Y' AND ID = '12345'
BEGIN TRY
UPDATE dbo.T1 set ReportDate= '9910-12-2006'
SET @Err1 = @@error
END TRY
BEGIN CATCH
insert into errorlog values (error_message())
END CATCH
--if @err1<>0
--begin
--Rollback transaction
--end
This work fine but I am not able to roll back the transaction
When I activate the codes fro roll back, it not performing the Logging operation in CATCH also terminating
REQUIREMENT
1) Get the record in T1 from T2 2) Update the record in T1 3) IF step:3 good commit it, else remove the only the row which was pulled from T2. It must do this also log in dbo.ErrorLog the errored system message error_message()
I have following query which is created dynamically as -
UPDATE Â BUILDTABLE Â SET BUILD_ID = Â '984137' Â WHERE SET_NUMBER = '1889147436' AND SEND_DATE = '1941-03-04';Â UPDATE Â BUILDTABLE Â SET BUILD_ID = Â '984137' Â WHERE SET_NUMBER = '1115509374' AND SEND_DATE = '1991-09-01';Â UPDATE Â BUILDTABLE Â SET BUILD_ID = Â '984137' Â WHERE SET_NUMBER = '1515579671' AND SEND_DATE = '1941-05-24';Â UPDATE Â BUILDTABLE Â SET BUILD_ID = Â '984137' Â WHERE SET_NUMBER = '1795509670' AND SEND_DATE = '1958-01-14'; UPDATE Â BUILDTABLE Â SET BUILD_ID = Â '984137' Â WHERE SET_NUMBER = '1915508672' AND SEND_DATE = '1961-09-07';
Here till " UPDATE BUILDTABLE SET BUILD_ID = Â '984137'" is the same clause for all queries, but "where" condition is different for all queries. I have to update more than 500 UPDATE statements(like above) in one call. Currently I am concatenating all the queries in string Builder which is time consuming.I want to increase performance of application.Any other class like BulkCopy ?
Hi, I am trying to use a formView with an update button to update individual records in an sql database. (when i click update it doesnt perform the update and just refreshes the page. ) One of the fields in my records is a NULL - this is also one of the fields that i need to update. When i manually go into the database and enter some data, and then go back to my form, it updates fine, but as soon as i delete the data from the field, it returns to NULL and im back to square one. Any Ideas on how to get around this problem?THanks
updating the # of Payer from below query to match with the # of rows for each payer record. See the Current and desired results below. The query is currently counting the # of rows for all payers together and updating 3 as # of payers. I need it to count # of rows for each payer like shown inDesired result below. It should be showing 1 for first payer and 2 for 2nd & 3rd based on # of times each payer is repeated..
SELECT b.FILING_IND, b.PYR_CD, b. PAYER_ID, b. PAYER_NAME,a.CLAIM_ICN, (Select Count(*) From MMITCGTD.MMIT_CLAIM a, MMITCGTD.MMIT_TPL b , MMITCGTD.MMIT_ATTACHMENT_LINK c where a.CLAIM_ICN_NU = c.CLAIM_ICN and b.TPL_TS = c.TPL_TS and a.CLAIM_TYPE_CD = 'X'Â
I want to update the STATUS column based on min date in my table.
For example – If minimum BOOKING_DATE of any RecieptID is below to 2015-10-01, then Status of that RecieptID should be 0 for all records pertaining to dedicated RecieptID So I need an output in this way.
I have this update statement that works for one record. How do I write it to include multiple records at once. Please see sample below.
update mklopt set  FRMDAT = '12/31/2014' where  JOBCOD = 'PH14789'Â
I also want to include the following instead of running it one at a time
PH17523Â Â Â Â PH17524Â Â Â Â PH17525Â Â Â Â PH17553Â Â Â Â PH17555Â Â Â Â PH17556Â Â Â Â PH17557Â Â Â Â PH17558Â Â Â Â PH17571Â Â Â Â PH17573Â Â Â Â PH17574Â Â Â Â PH17575Â Â Â Â PH17576Â Â Â Â PH17577Â Â Â Â PH1757
I have a column with XML data stored in it. I need to update that column several times with new values for different nodes. I've written a CLR function to update the XML quickly but the update is always based on the initial value of the xmlData column. I was hoping that the subsequent updates would be based on the new data from the prior update (each xmlTable has several newData rows). Do I have to make this a table valued function and use cross apply?
UPDATE xmlTable SET xmlTable.xmlData = Underwriting.UpdateByDynamicValue(xmlTable.xmlData,newData.NodeID,newData.NewValue) FROM xmlTable JOIN newData ON xmlTable.ID = newData.fkXmlTableID
We have our Production server having database on which Few DTS packages execute every night. Most of them have Bulk Insert stored procedures running.
SO we have to set Recovery Model of the database to simple for that period of time, otherwise it will blow up our logs.
Is there any way we can set up log shipping between our production and standby server, but pause it for some time, set recovery model of primary db to simple, execute DTS Bulk Insert Jobs, Bring it Back to Full recovery Model AND finally bring back Log SHipping.
It it possible, if yes how can we achieve this.
If not what could be another DR solution in this scenario.
Let me explain. When retrieving a row, an extra column should be added.It's value should be the sum of previous rows whose type is the same with the encountered one. I made it with a function but it's performance was terible with large tables. I have tables larger then fifty housands rows.
I have got a table with GUID (PK), COMPANY, CONTACT. There are going to be instances where the company name is the same on multiple records.
What i am trying to do is work out what is the next and previous record
The data is going to be sorted, by COMPANY then GUID.
I am think a stored procedure would be the best to combact this, but very usure how to go about writing it, so i passed the present company and GUID values to it.
Any help would be appreciated, and thanks in advance.
Hi,In oracle I have a LAG function using which I could get the previousvalue of a field.Do we have anything similar to that in SQL Server or access?ThanksDevi
