How To Update One Column To Be The Same For All Records In Database Table?
May 6, 2007Hi,
I have a set of records in database table and I want to update one column to be the same for all of them.
Can you suggest code solution?
Hi,
I have a set of records in database table and I want to update one column to be the same for all of them.

My question is concerned with the three columns below (customerID, RepairDate, CompletedRepair (Yes or No). The column name "CompletedRepair " is blank initially. I need to update the CompletedRepair column with this logic below:
- A customer comes to our store to fix their car, if we fix their problem on the first time and they don’t return later for this same issue, then the
•CompletedRepair column = Y
- If a customer needs to come back to our store to re-fix the same issue within 7 days windows based on the RepairDate on the previous transaction then
•On the last return transaction: CompletedRepair = Y (example: RepairDate =6/12/2006)
•On all previous transactions: CompletedRepair = N (example: RepairDate =6/8/2006, 6/9/2006, 6/10/2006)
- If a customer needs to come back to our store to re-fix the same issue but out of the 7 days windows based on the RepairDate then
•On the last return transaction: CompletedRepair = Y (RepairDate =6/12/2006)
•On the previous transaction: CompletedRepair = Y (RepairDate =6/1/2006)
Every time customer comes to for car repair shop for a new issue or an old issue, we create a new repair transaction in our SQL db. The update on the "CompletedRepair " column will be run every day. Today's records will be run against with last 7 days records (based on Repair Date) to check when customer has been really fixed: the last fix counted Y, the previous fix counted as N but comparison in only 7 days. In other words, a repair today is considered as a completed repair when comparing with last 7 day repairs but it might become not a completed repair if this same customer would come back within next 7 days for the same issue.
The CompletedRepair column is dynamic column and is updated daily by using the logic above.
Below is the expected outcome after we update the Completed Repair column:
CustomerID Repair DateCompleted Repair
ab1 06/12/06 Y
ab1 05/28/06 Y
ab1 05/18/06 Y
ab105/15/06 N
ab1 05/12/06 N
Initially 5/12/06 had Y, when 5/15/06 transaction came, it took the Y and made the 5/12/06 become N. The 5/18/06 transaction did the same to 5/15/06 transaction, made itself Y and converted 5/15/06 into N. The 5/28/06 is Y because comparing with 5/18/06, it is out of 7 days window. The 6/12/2006 is Y because comparing with 5/28/06, it is out of 7 days window.
ab2 06/02/06 Y
ab2 05/28/06 N
ab2 04/19/06 Y
ab2 04/14/06 N
The 4/14/06 transaction initially was Y, it became N when new transaction on 4/19/06 came. Same thing with transactions on 5/28/06 and 6/2/06
ab3 05/11/06 Y
ab3 03/29/06 Y
ab3 03/23/06 N
ab3 03/12/06 Y
The 3/23/06 was Y, when new transaction on 3/29/06 came, it became N and the new transaction is Y. The 5/11/06 is Y because comparing back to 3/29/06, they are out of 7 days window.
ab4 05/11/06 Y
This ab4 customer came to fix her car only one time and don't come back. We supposed the fix was sucessfully and so we mark the CompletedRepair as Y.
I think that I would need to use SQL cursor or case statement for this but I really don't know how to start. Please advice and help me out. Any ideas and suggestion are really appreciated! If you need more information, please let me know!
Thank you!

I am trying to exclude records from a table where the ID column is the same but the Mail code Column is multi-valued.For Example: (the table looks like....)
ID Mail_code
111111 XNT
111111 N11
111111 XNC
222222 XNC
222222 XNL
333333 XNC
So, if there is any ID that has a value of XNC, I want to exclude the ID all together from my output regardless of the other values.

View 3 Replies View RelatedI have a scenario where I have to Update a table with date when there are new records in another table
For example:
I load ODS table with the data from a file in SSIS. the file has CustomerID and other columns.
Now, when there is new record for any customerID in Ods, then Update the dbo table with the most recent record for every CustomerID(i.e. update the date column in dbo for that customerID). Also Include an Identifier that relates back to the ODS table. How do I do this?
I am trying to update one table when records are inserted in another table.
I have added the following trigger to the table “ProdTr” and every time a record is added I want to update the field “Qty3” in the table “ActInf” with a value from the inserted record.
My problem appears to be that I am unable to fill the variables with values, and I cannot understand why it isn’t working, my code is:
ALTER trigger [dbo].[antall_liter] on [dbo].[ProdTr]
for insert

declare @liter as decimal(28,6)

How to use db-lib to update/insert database records without using SQLlanguage. I want to change the value of the data individually withoutplugging in the new values in the SQL language then execute it. Theperfect situation for me is loop through the retrieved records thenedit the values individually until EOF.Thanks,Carlo

Every day the timestamp is changed on all rows in one of the table(table has 1 mio records).
What is the best way to find out which query is doing this?
Could be also query which updates only one record(or couple of them) but is executed for each record once.
I have been looking sys.dm_exec_query_stats and sys.dm_exec_sql_text for past but couldn't find.
I can't use event notifications since there is service broker disabled.
Hello,
I have been serching for weeks to resolve this problem. I am new to ASP.NET and trying to make the migration from ASP which I have programmed in for years. I am using Microsoft Visual Web Developer 2005 Express Edition and SQL Express Edtion. I have been working through the Microsoft Video Training at http://msdn.microsoft.com/vstudio/express/beginner/learningpath/ and created a web site using Tier 3 Lesson 8 as the model. My new web site which is a simple phone book applicaiton lets me read the table and select the record without any problem. But the update form lets me edit but when I attempt to Apply the update I get the following error.
Server Error in '/Phonebook' Application.
ObjectDataSource 'ObjectDataSource1' could not find a non-generic method 'Update' that has parameters: FirstName, LastName, PhoneNumber, BossGroup, Department, BossPickup, ShowInPhonebook, Type, Original_FirstName, Original_LastName, Original_PhoneNumber, Original_BossGroup, Original_Department, Original_BossPickup, Original_ShowInPhoneBook, Original_Type, Original_ItemID.
Description: An unhundled expception occured during the execution of the current web request. Please review the stack trace for more information about the error and where it originiated in the code.
The Stack Trace basiclly showes the same error as above.
Also, when I attempt to delete the record I do not get an error but the record does not delete.
What is interesting is that I can add a record so I do not believe that it is a security permissions issue. I have the ISS Authinication Method Enable Anonymous Access set on with full control.
If anyone has any insight as to why this is occuring please let me know.

What I want to do is update the table so that it populates the PERCENTAGE column on an empref/hrscode/date basis based on the sum of the WRK hours per day and empref.
EG for 2014-09-01 for empref 001 the result would be
Code:

IE Sum WRK = 486 so 180 is 37.037 percentage. Each HRSCODE hours total should total 100% (37.037 + 61.728)
I can write a query to do this individually but how can I so this as a query for the full table.
Code:
declare @@total as float
set @@total=(select SUM(hours) from tmsuser.tmswrhrs where hrscode='worked' and empref='001' and '2014-09-01 00:00:00.000'=procdate)

I need to update more than one record at once. I have ~ 100 records that I have to update and don't want to execute query 100 times.
My query looks like this:
Update Table1
Set Table1.field1 = ( select Table2.field1 from Table2 where Table2.field2 IN ('a', 'b', 'c')
where Table1.field2 IN ( 'a', 'b', 'c')
It obviously failed because subquery returned more than one value and error message stated that I can't use '=' operator in this case.
My question: how could I update the same column from many records in one execution?
I am trying to update a parent table with a summation of its child records. The child records are being deleted because the transaction has become invalid because payment was made with a bad check or there was a posting error. So a rollback of sorts is required.
Here are is the DDL for the tables and DML for the data:
Code:
DECLARE @t1 TABLE
(
[Year] int NOT NULL,
[Parcel] varchar(13) NOT NULL,
[InterestDateTime] datetime NULL,
[Principal] decimal(12, 2) NULL,
[Penalty] decimal(12, 2) NULL,
[Code] ....
I tried to use a Merge statement with an ON MATCH for each TransType, but it complained that I could not have multiple update statements. OK. So I tried a MERGE with single update statement with a case and it complained that I was updating the same parent multiple times, which I was and want to! So, I tried the following update statement and it still does not work, though no error message.
Code:
update t1 set
t1.Principal = t1.Principal + (case when t2.TransType = 'R' then t2.Payment else 0 end),
t1.Penalty = t1.Penalty + (case when t2.TransType = 'P' then t2.Payment else 0 end),
t1.Interest = t1.Interest + (case when t2.TransType = 'I' then t2.Payment else 0 end)
from @t1 t1
inner join @t2 t2 on t2.YEAR = t1.YEAR and t2.Parcel = t1.Parcel
I am expecting the following after the update:
Code:
Select * from @t1

All I am getting are the original values.
I want to update records in 1 table with the result of a select statement.
The table is called 'MPR_Portfolio_Transactions' and contains the following fields:
[PTR_SEQUENCE]
,[PTR_DATE]
,[PTR_SYMBOL]
,[PTR_QUANTITY]
,[PTR_ACUM]
And the select statement is like this:
SELECT SUM(PTR_QUANTITY) OVER (PARTITION BY PTR_SYMBOL ORDER BY PTR_DATE, PTR_SEQUENCE) AS 'ACUMULADO'
FROM MPR_portfolio_transactions
ORDER BY PTR_SYMBOL, PTR_DATE, PTR_SEQUENCE
This select statement generates one line per existing record. And what I would like to do next is to UPDATE the field 'PTR_ACUM' with the result of the 'ACUMULADO'
the key is PTR_SEQUENCE
I have a table called acc1152 with the field accno. depending on what the value of this field is, i need to replace it with a new value. These are the values i need to update
old value new value

how do I write one query that will accomplish this?
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.
How to Update Column Value in the whole data base (based on Column Value)?

I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.
This is my statement:
UPDATE [dbo].[sessions_teams] stc
SET stc.[Talks] = fmt.found_talks_type
FROM @Find_Missing_Talks fmt
WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks)
AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)

We are facing a weird scenario in which the snapshot is getting corrupted after insertupdate few million records in to a table .
SQL Server 2012
windows server 2008 R2
service pack 1
64-bit OS
Our system runs a SQL Server 2012 DB, it has a table (table_a) which has over 10M records. Our system have to receive data file from previous system daily which contains approximate 3M updated or new records for table_a. My job is to update table_a with the new data.
The initial solution is:
1 Create a table (table_b) which structur is as the same as table_a
2 Use BCP to import updated records into table_b
3 Remove outdated data in table_a:
delete from table_a inner join table_b on table_a.key_fileds = table_b.key_fields
4 Append updated or new data into table_a:
insert into table_a select * from table_b
As the test result, this solution is very inefficient. Step 3 costs several hours, e.g. How can I improve it?
Godwin writes "Hello,
Heres my question..
I have 2 tables.2 paticular columns exist in both the tables.
I want to be able to select those 2 columns on the 1st table and insert them on to the same 2 columns on the 2nd table.
Now,this 2nd table has another 3 columns that exist in another table.I would like to take those 3 column values from that 3rd table and insert it into the 2nd table by modifying those existing records in the 2nd table.In the 3rd table,there will be around 5 records...I want to copy the existing records 5 times in the 2nd table and insert the 3rd tables rows inside the 2nd table in that respective column for 5 rows.
I hope you understand what I mean...Im sorry for really confusing..
Please help me
Thanks

I am currently working with C and SQL Server 2012. My requirement is to Bulk fetch the records and Insert/Update the same in the other table with some business logic? How do i do this?
View 14 Replies View RelatedNeed to update one table with value of a column in another table plus a constant:
UPDATE TABLE_A
SET TABLE_A.COLA=TABLE_B.COLB+'10'
FROM TABLE_A
INNER JOIN TABLE_B
ON TABLE_A.COLA=TABLE_B.COLA
WHERE TABLE_A.COLA=TABLE_B.COLA
The above statement works except the concatenated string has space between TABLE_B.COLB text and '10'. How to remove the space (4 characters) so that the string shows as one word 'TABLE_B.COLB10'?
