Seperate Date And Time Merge; Done At SQL Update Or C# .NET Then Update
Feb 18, 2006
I do realize that his could be posted in a few spots but I think the answer is in the SQL.
I have a ASP.NET page, with a SqlDataSource, Text Box and Calendar Controls. I have the textbox and calendar controls eval'ed to the same sql data source DateTime Field. The text box is formatted eval to small time and the calendars eval has no formatting.
I want to merge the two controls; one has the date the other has the time when I update the pages data to the SqlDataSource field EVENT_START. I've tried a couple of methods, but I would like some other opinions. As Sql server only supports date and time together I am storing the two together.
I could merge the two together in the code behind on the update button's event handler or merge the two during the update query using parameters.
Not that I could get an illegal date for the calendar control, but I could get garbage from the textfield time. So I still would have to do validation on the text field before the SQL server could do the update.
There's a few ways to go about this, so I was wondering if anyone else has figured out an elegant way to handle it.
hi! i'm new to sql and working on my first database, I use microsoft sql server 2000 - in my table i want a row in which date and time is saved whenever the dataset is changed. I use getdate() as default value and it saves the time when I create a new entry, but not yet when I update an old one. I know that it must be a formula with something like update tbl set = getdate() but I don't know exactly how it works. any help on this?
How can I set a column in a table to auto update the date and time everytime something in that row is updated or when the row is first added? Thanks ahead for the help,Jason
I know 2008 MS SQL Server has a timestamp data type that adds date and time when the rows are inserted. Is there a way to automatically update the date and time when the rows are updated?
need help please on update only if . i need to update only the field "val_holiday " (in table B from table A) and olso to check on table B the "ID" + "new_date" only if exist and update the field "val_holiday " (in table B)
and at the end of update change the field "field_check_update_if _ok" from 0 to 1 only the row that update in table B
Code Snippet select from table A update table B WHERE ..........................HOW ?
----------------------------------------------------------------- table A ID fname new_date val_holiday field_check_update_if _ok ---------------------------------------------------------------------------------------------------
----------------------------------------------------------------- table B ID fname new_date val_holiday ----------------------------------------------------
I hope to update a DateTime column value with a Time input parameter.  Poor attempt below but it looks like the @ApptTime param is coming in as 10:45:00.0000000 and I might have an existing @SendOnDate as: 2015-10-05 07:00:00.000...I hope to end up with 2015-10-05 10:45:00.000
ALTER PROCEDURE [dbo].[SendEditUPDATE] @QuePoolID int=null ,@ApptTime time(7) ,@SendOnDate datetime
Hi, I feel like this should be fairly simple but I just can't seem to get it! I basically want to update multiple records using a sub-query.
I have two tables: objects and temp1. Both have identical column names: Un_ID and SerialNum (one has serial numbers while the other has mostly Null values for the serial numbers). I want to update the SerialNum column in "objects" with the SerialNum column from temp1. The two tables can be linked by un_id's.
Here is my update statement: UPDATE Objects SET SerialNumber = (SELECT SerialNumber FROM temp1) WHERE (objects.Un_ID = temp1.un_id) The error I receive says "column prefix "temp1" does not match a table name or alias name used in the query".
I think the step I am missing is actually liking the two tables in the update statement. Can anyone help?
How to Insert,Update and delete through script without using merge.I have simple requirement of Deleting,Inserting and Update from one table to other table...Here is the Sample Data
CREATE TABLE #Table1 (ID INT ,Name VARCHAR(30),DATEKEY INT) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (1,'Mohan',20131231) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (2,'Raj',20131231) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (3,'Majja',20131231) INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (4,'Majjaa',20131231)
[code]...
So now i need to update 1st record and add another new record..So i need to update as well as delete the existing data in Target table.
INSERT INTO #Table1 (ID,Name,DATEKEY)VALUES (5,'Macha',20131231)
My output should come like this one :
IDNameDATEKEY 1Mohan20131231 5Macha 20131231
with out using merge how can i handle Update,insert and Delete through TSQL
Hi, I'am using several SQL 2000 servers with different working merge-replications. Actually I wrote a .NET assembly which makes updates to key values in one of the replicated tables:
Ex: update ReplTable set key = -key where key between (1 and 100)
Loop ...... update ReplTable set key = NewKey where key = .... end of loop
Intention is to resort the datarows. So I made two updates to every keyvalue in a very short time. At the ConflictViewer I got messages like:
"The row was inserted at 'ServerX' but could not be inserted at 'ServerY'. Violation of PRIMARY KEY constraint 'PK_xxxx. Cannot insert duplicate key in object 'ReplTable'. "
The replication did only deliver one (the last) update - this makes the violation. Is there a possibility to make the mergeagent known that I wanted to deliver every transaction? Is there a parameter in the agents profile?
I have to load 2 flat file of 2 Gb each in a table. I found 2 ways to do that: - Either I read my 2 file in parallels and I use a merge join transformation to merge my data. Then I load theses datas in my destination table - Or I insert all my first file in the destination table then I read the second file and update my table with the new information.
Based on your experience, what is the best ? I'm running the first way for more than 30 minutes and SSIS is still sorting my datas.... (sort before the merge join)
In the following t-sql 2012 merge statement, the insert statement works but the update statement does not work. I know that is true since I looked at the results of the update statement:
Merge TST.dbo.LockCombination AS LKC1 USING (select LKC.comboID,LKC.lockID,LKC.seq,A.lockCombo2,A.schoolnumber,LKR.lockerId from [LockerPopulation] A JOIN TST.dbo.School SCH ON A.schoolnumber = SCH.type
[Code] ...
Thus can you show me some t-sql 2012 that I can use to make update statement work in the merge function?
I am trying to create Replication Topology (Merge Replication) like below.
Subscriber1 --> Publisher <-- Subscriber2.
I have created both subscribers with Subscription Type as Server with Priority as 75. I am updating the Column A of Row_10 in Subscriber1 on time say 11 am. After i am running the Starting synchronizing agent from Subscriber1. The value propagated to Publisher now publisher contains the latest value in Column A. Uptonow the Subscriber2 is not synchronized with Publisher.
Now in Subscriber2 also Column A of Row_10 is updated say at 11.10 am. Actually now Publisher contains the value from Subscriber1 for that Column and in Subscriber2 we have the same column updated.
Now i am running the Synchronization in Subscriber2, i am getting the result which is not expected. Here Publisher's value is propagated to Subscriber2. But as per real scenario Subscriber2 has the Latest value which is updated on 11.10 AM.
I don't know what am i missing here. Actually merge replication should see the time stamp and it has to decide winner. But here it always considers publisher as a winner and puts the data to Subscriber.
I have got a business logic update conflict handler working, but I have had to work round what appears to be a bug.
Please can someone confirm if this is indeed a bug €“ and if it is a known bug?
My conflict handler needs to take some columns from the publisher row and some from the subscriber row in the event of conflict.
I can quite happily generate a custom dataset which contains the winning row that I want €“ I can see that because I can step through the conflict handler with debug when a conflict occurs.
However, just returning ActionOnUpdateConflict.AcceptCustomConflictData from the UpdateConflictsHandler method does not set the publisher and subscriber columns correctly. I end up with different values on the two databases.
I have found that the only way to get the correct rows on both publisher and subscriber is to create a new ADO connection to the publisher and actually perform an update €“ updating all the modified columns. This now works reliably in my testing.
Fortunately, due to business rules the frequency of update conflicts are likely to be very infrequent, but I would very much like to avoid having to do the €˜unnecessary€™ update.
Notes:
I am using column level tracking €“ but I have seen the problem with row level tracking too I have mainly been using SP1 but have repeated the test on a configuration using the SP2 CTP €“ and the problem occurs there too The problem is not due to complex logic in my code. If the method just sets customDataSet = publisherDataSet.Copy and then returns ActionOnUpdateConflict.AcceptCustomConflictData, the changed and winning publisher values are not sent to the subscriber
I want to compare two columns in the same table called start date and end date for one clientId.if clientId is having continuous refenceid and sartdate and enddate of reference that I don't need any caseopendate but if clientID has new reference id and it's start date is not continuous to its previous reference id then I need to set that start date as caseopendate.
Hi,I have a problem with updating a datetime column,When I try to change the Column from VB I get "Incorrect syntax near'942'" returned from [Microsoft][ODBC SQL Server Driver][SQL Server]'942' is the unique key column valueHowever if I update any other column the syntax is fineThe same blanket update query makes the changes no matter what isupdatedThe problem only happens when I set a unique key on the date field inquestionKey is a composite of an ID, and 2 date fieldsIf I allow duplicates in the index it all works perfectlyI am trying to trap 'Duplicate value in index' (which is working onother non-date columns in other tables)This is driving me nutsAny help would be appreciated
I have created a Dynamic Merge statement SCD2 Store procedure , which insert the records if no matches and if bbxkey matches from source table to destination table thne it updates old record as lateteverion 0 and insert new record with latest version 1.
I am getting below error when I ahve more than 1 bbxkey in my source table. How can I ignore this.
BBXkey is nothing but I am deriving by combining 2 columns.
Msg 8672, Level 16, State 1, Line 6
The MERGE statement attempted to UPDATE or DELETE the same row more than once. This happens when a target row matches more than one source row. A MERGE statement cannot UPDATE/DELETE the same row of the target table multiple times. Refine the ON clause to ensure a target row matches at most one source row, or use the GROUP BY clause to group the source rows.
2 Users in 2 locations issue updates to the same table. 1 updating 1 column and the other updating another column. Now in reality the actual Stored Procedure issuing the update statement is passed in all the possible columns that could change and builds an update statement that updates all columns even the ones that havent changed.
Will this break Merge Replications conflict tracking? Or does SQL Server 2005 Merge Replication pickup that in reality the 2 updates only in reality changed the values in 2 columns.
We have a big problem here with merge replication, specifically whenever a schema change occurs. We are replicating schema changes, and triggers/stored procedures. The example is that we changed about 150 stored procedures and about 30 triggers. This is then replicated to the subscriber database (which is also a merge publisher for further remote systems that were offline at the time) over a 10Mb link - hardly low bandwidth. However, the replication process takes about an hour and a half - considering the SQL on the primary server took less than a minute to run this is a big suprise.
We've run a trace to see if we can identitfy what is going on. There seems to be a great number of calls to sp_MSunmarkschemaobject - we are still waiting for a trace to complete to fully analyse this however it looks like it calls this repeatedly for every stored procedure in the database. We are currently re-testing to one of the remote servers with the merge agent set to the slow profile (not much hope that this will alter the poor performance).
This task looks to be excessive - and certainly does not seem to function in a sensible manner. Has anyone else had similar issues or have any suggestions. This is very infuriating as it means that the servers are effectively offline for a minimum of and hour and a half (in fact the remoter servers take over 4 hours !).
I have a reference table that currently has no web front-end. It's a small table(<10 rows) that's not going to change very often (maybe once every few months).
We manually update rows on the table via the GUI table interface in Enterprise Mgr., not in T-SQL.
What I'd like to do is have SQL Server automatically update the "Last_Modified" column with the current timestamp. I can do it on an Insert using the GetDate() function, but if I update a row, this doesn't work.
Is there a function I can use that can auto-populate for both insert and updates?
I am using ASP to insert/delete/update rows into a very simple SQLServer database (2000).When a certain amount of text (as little as 1000 chars) is inserted tothe table (the insert works fine) ANY update call to that row will timeout.I can set the time out for 5 minutes and it still times out udatingeach field to to null.Woudl this have anything to do with row locking?Has any one ran into this problem and solved it?Thank for your help,MB

I would like to limit the number of pages a user can view on my website each day. The users logs in and I can count the number of pages viewd in a field but i want to know how i can set the page count field to reset to 0 at the end of the day (ie midnight). Is it possible to do this? and if so how? Thanks.
Hi, I'm trying to use the Update command to change a field value. I only know the field name at run-time, how do you write this command. This is what I have done which just sets the variable @cFieldName to the value and not the field within the table.
UPDATE [Atable] SET @cFieldName = @aValue WHERE ([Id] = @Id_1)
