UPDATE Table From A Remote DB OR INSERT If Doesnt Excists.
Sep 2, 2004
I have been looking for a solution for this for some time and have came up empty handed.
I have 2 servers development box and a live box. Time has passed and my live box has a lot of new data in the database and now I need to update the dev box so I can properly test with real data. Problem here is I want to keep the records that are in the dev box, update them if they exsist on the live box, because live server may or may not contain that record and isert all records that are not on the dev box database.
I hope I am making some sense here, I think I am just making it more difficult then it has to be.
I have an application that uses a MS SQL 2005 database. When data is changed in certain tables, that data needs to be pushed to a MySQL box. I've added the MySQL server as a linked server in SQL 2k5 and I can delete and insert data with no problem, however when I try to update I get the following error (query included):
Code Snippet
with RemoteTable(r_AccountID, r_Name) as (select AccountID, Name from openquery(RACS_TEST, 'select AccountID, Name from accounts')) update RemoteTable set r_Name = ex_Name from Export_RACS_Accounts join remotetable on r_AccountID = ex_AccountID
OLE DB provider "MSDASQL" for linked server "RACS_TEST" returned message "Row cannot be located for updating. Some values may have been changed since it was last read.". Msg 7343, Level 16, State 4, Line 33 The OLE DB provider "MSDASQL" for linked server "RACS_TEST" could not UPDATE table "[MSDASQL]". The rowset was using optimistic concurrency and the value of a column has been changed after the containing row was last fetched or resynchronized.
Greetings -I'm using an Access front end to a SQL Server (2000) databas*e. Viaseveral steps, I create a temp table and manipulate the data* in it.Iwant to update the backend with this new data but my UPDATE *queryfailsas my temp table is local and the SQL database doesn't know *about it.There are no linked tables in the FE database.I have the following (DAO):Set Db = CurrentDbSet Qdf = Db.CreateQueryDef(TMP_QUERY_NAME)Qdf.connect = ConnectString()sqlString = "UPDATE tblRemote " & _"SET " & _"tblRemote.Some_Foo = tblLocal.Foo, " & _"FROM tblRemote INNER JOIN tblLocal " & _"ON tblRemote.Some_ID = tblLocal.Some_ID;"Qdf.sql = sqlStringQdf.ReturnsRecords = FalseQdf.Execute dbFailOnErrorIs there any way of doing this without adding a linked table*?Thanks, chris
table2 is intially populated (basically this will serve as historical table for view); temptable and table2 will are similar except that table2 has two extra columns which are insertdt and updatedt
process: 1. get data from an existing view and insert in temptable 2. truncate/delete contents of table1 3. insert data in table1 by comparing temptable vs table2 (values that exists in temptable but not in table2 will be inserted) 4. insert data in table2 which are not yet present (comparing ID in t2 and temptable) 5. UPDATE table2 whose field/column VALUE is not equal with temptable. (meaning UNMATCHED VALUE)
* for #5 if a value from table2 (historical table) has changed compared to temptable (new result of view) this must be updated as well as the updateddt field value.
Two tables t1 and t2 have the same schema but exist on two different servers. Which is the better technique for updating t2 and why?

-- Technique 1:
set identity_insert t2 on
insert into t2 (k,a,b,c,x,y,amt) select k,a,b,c,x,y,amt from t1 where not exists (select k from t2 where t1.k = t2.k)
set identity_insert t2 off
update t2 set a = t1.a, b = t1.b, c = t1.c, x = t1.x, y = t1.y, amt = t1.amt from t1 where t1.k = t2.k
-- Technique 2: set identity_insert t2 on
declare t1_cur cursor for select k,a,b,c,x,y,amt from t1 for read only
open t1_cur
declare @k int declare @a char(10) declare @b char(10) declare @c char(10) declare @x int declare @y int declare @amt money
fetch next from t1_cur into @k,@a,@b,@c,@x,@y,@amt while(@@FETCH_STATUS = 0) begin if exists(select k from t2 where k = @k) begin update t2 set a = @a, b = @b, c = @c, x = @x, y = @y, amt = @amt where (k = @k) end else begin insert into t2 (k,a,b,c,x,y,amt) values(@k,@a,@b,@c,@x,@y,@amt) end

Hi all,We have an application through which we are bulk inserting rows into aview. The definition of the view is such that it selects columns froma table on a remote server. I have added the servers usingsp_addlinkedserver on both database servers.When I call the Commit API of oledb I get the following error:Error state: 1, Severity: 19, Server: TST-PROC22, Line#: 1, msg:SqlDumpExceptionHandler: Process 66 generated fatal exception c0000005EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.I would like to know if we can bulk insert rows into a view thataccesses a table on the remote server using the "bulk insert" or bcpcommand. I tried a small test through SQL Query Analyser to use "bulkinsert" on a such a view.The test that I performed was the following:On database server 1 :create table iqbal (var1 int, var2 int)On database server 2 (remote server):create view iqbal as select var1,var2 from[DBServer1].[SomeDB].[dbo].[iqbal]set xact_abort onbulk insert iqbal from '\MachineIqbaliqbaldata.txt'The bulk insert operation failed with the following error message:[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionCheckForData(CheckforData()).Server: Msg 11, Level 16, State 1, Line 0General network error. Check your network documentation.Connection BrokenThe file iqbaldata.txt contents were :112233If the table that the view references is on the same server then weare able to bulk insert successfully.Is there a way by which I should be able to bulk insert rows into aview that selects from a table on a remote server. If not then couldanyone suggest a workaround. I would actually like to know someworkaround to get the code working using OLEDB. Due to unavoidablereasons I cannot output the records to the file and then use bcp tobulk insert the records in the remote table. I need to have some wayof doing it using OLEDB.Thanks in advanceIqbal
We need to Insert/Update a Fact Table from staging Table. currently we are using a SP which update Fact Table for Each region. this process is schedule, every 5 min job is run and Update fact table.but time of Insert and Update too long from staging to Fact, currently we are using merge statement for Insert and update.in my sp we are looping number how many region we need to update and at a time single Region we are updating using while loop in current SP.
I want to make a query, stored procedure, or whatever which will only display the primary key where there does no exist a foreign key in linked table.For example. If I had two tables with a one to many relationship.A [Computer] has one or more [Hard Drives]. I want to select only those computers which do not have a Hard Drive(s) associated with them. That is, show all computers where the Computer_ID field in the [Hard Drives] table does not exist. This seems simple but I'm drawing a blank here.
I have two different SQL 2008 servers, I don't have permission to create a linked server in any of them. i created a trigger on server1.table1 to insert the same record to the remote server server2.table1 using OPENROWSET
i created a stored procedure to insert this record, and i have no issue when i execute the stored procedure. it insert the recored into the remote server.
The problem is when i call the stored procedure from trigger, i get an error message.
Stored Procedure: USE [DB1] GO SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON
[Code] ....
When i try to insert a new description value in the table i got the following error message:
No row was updated the data in row 1 was not committed Error source .Net SqlClient Data provider. Error Message: the operation could not be performed because OLE DB provider "SQLNCLI10" for linked server "(null)" returned message "The partner transaction manager has disabled its support for remote/network transaction.".
correct the errors entry or press ESC to cancel the change(s).
I'm importing XML file into DataTable and need to Insert Data into SQL Table. I'm not sure if its posible to take a DataTable with Data and insert into DataAdapter. From there i wanted to update SQL using TableAdapter? Any Tips? Thanks,
This should be easy for someone, but I just can't seem to find a sample to do this.....I have created a table...CREATE TABLE dbo.test ( oId int NOT NULL UNIQUE, test1 varchar(50) NOT NULL PRIMARY KEY )Now, I need to go back and simply add another column to the table such as test2 varchar(50)Not sure if the insert is the way to go and been playing around with various statements but with no luck.Suggestions?Thanks all,Zath
I am new to triggers and need help on the following:
I have a hourly table that inserts new rows every hour but I need to either Insert or Update the daily table with the sum of the reading from the hourly table. If a row exist in the daily table with the date of the hourly table, then I need to update this row but if it doesn't exist, I need to insert this row.
I currently have 2 tables as follows:CREATE TABLE [CRPDTA].[F55MRKT119](mhan8 int,mhac02 varchar(5),mhmot varchar(5),mhupmj int)GOCREATE TABLE [CRPDTA].[F55MRKT11](mdan8 int,mdac02 varchar(5),mdmot varchar(5),mdmail int,mdmag int,mdupmj int)What I would like to do is place a trigger on F55MRKT119 which willinsert records to the F55MRKT11 if they do not exist in that tablebased on the [mdan8] field. If the record does exist I would likeUpdate the corresponding record and increment either the [MDMAIL] orthe [MDMAG] based on the inserted [MHMOT]. What I have so far is asfollows:TRIGGER #1:CREATE TRIGGER trgIns_Summary ON [CRPDTA].[F55MRKT119]FOR INSERTASBEGININSERT INTO CRPDTA.F55MRKT11select INS.MHAN8, INS.MHAC02, INS.MHMOT,case when INS.MHMOT='MAG' then 0 ELSE 1 end,case when INS.MHMOT='MAG' then 1 ELSE 0 end,'0' from INSERTED INSWHERE ins.mhan8 not in(select mdan8 from crpdta.f55MRKT11)ENDTRIGGER #2:CREATE TRIGGER trgUpd_Summary ON [CRPDTA].[F55MRKT119]FOR UpdateASBEGINUPDATE CRPDTA.F55MRKT11SET MDMAIL= case when INS.MHMOT='MAG' then 0+MDMAILwhen INS.MHMOT<>'MAG' then 1+MDMAIL end,MDMAG= case when INS.MHMOT='MAG' then 1+MDMAGwhen INS.MHMOT<>'MAG' then 0+MDMAG endfrom INSERTED INS JOIN CRPDTA.F55MRKT11on(ins.mhan8=mdan8)ENDFor instance if I do the following insert:INSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','AL4','0')thenINSERT INTO CRPDTA.F55MRKT119VALUES('212131','VK4','MAG','0')This is what I expect in both tables:[CRPDTA.F55MRKT119] (2 Records)MHAN8 MHAC02 MHMOT MHUPMJ------ ------ ----- ------212131 VK4 AL4 0212131 VK4 MAG 0[CRPDTA.F55MRKT11] (1 Record)MDAN8 MDAC02 MDMOT MDMAIL MDMAG MDUPMJ----- ------ ----- ------ ----- ------212131 VK4 AL4 1 1 0The insert part works fine in that it iserts in both tables with thecorrect values. However it seems as if the Update protion is failingfor some reason. WHat I have tried so far is setting the trigger orderfor the update to run first and vice-versa, but still no luck. Anyhelp would be appreciated.
Hi,Does anyone know of a simple way to do this? I want to create aninsert trigger for a table and if the record already exists based onsome criteria, I want to update the table with the values that arepassed in via the insert trigger without having to use all the 'set'statements for each field (so if we add fields in the future I won'thave to update the trigger). In other words, I want the trigger codeto look something like this:if exists (select * from TableA where Fld1 = inserted.Fld1) then//don't do insert, do an update instead (would i want to rollback here?and will I have access to the 'inserted' table still?)Update TableASet TableA.<all the fields> = Inserted.<all the fields>where Fld1 = inserted.Fld1end ifAny help or ideas would be appreciated.Thanks,Teresa
I have a scenario where two tables are in a One-to-Many relationshipand I need to move the data from the Many table to the One table sothat it becomes a One-to-One relationship.I need to salvage the records from the many table and without goinginto detail, one of the reasons I can't do the opposite asthere are records in the ONE table that I need to keep even if theydon't have any child records in the MANY table.Below I created the code to create the sample tables:1- tblProducts is the ONE side table2- tblProductDetails is the MANY side table3- tblProductsResult is the RESULT I expect to get after runningsome T-SQL code4- tblProductComponents is another MANY side table to tblProducts5- tblProductComponentsResult is the RESULT I expect to get...Some of the points to consider:6- Normally all UniqueID columns are to be IDENTITY. Forthis sample i am entering the UniqueID values myself.7- I don't want to create new tables like tblProductsResultand tblProductComponentsResult. I want to update the real tables.I have created the tblxxxResult tables only for this post.8- The goal is to update the name of the Product by giving it thename of the first matching Name from tblProductDetails.9- If there are more than one entry in tblProductDetails for eachProduct, then I need to create new Products inheriting the originalProduct's information including its child records from tblProductComponents.If you run the code and open the tables it will be much clearerto visually see what I want to achieve.CREATE DATABASE MyTestDBGOUSE MyTestDBGOCREATE TABLE [dbo].[tblProducts] ([UniqueID] [int] NOT NULL PRIMARY KEY ,[Name] [varchar] (80) NULL,[TagNo] [int] NULL) ON [PRIMARY]GOINSERT INTO tblProducts VALUES (1, 'ABC', 55)INSERT INTO tblProducts VALUES (2, 'DEF', 66)INSERT INTO tblProducts VALUES (3, 'GHI', 77)INSERT INTO tblProducts VALUES (4, 'JKL', 88)CREATE TABLE [dbo].[tblProductDetails] ([UniqueID] [int] NOT NULL PRIMARY KEY ,[Name] [varchar] (80) NULL,[ProductID] int) ON [PRIMARY]GOINSERT INTO tblProductDetails VALUES (1, 'ABC1', 1)INSERT INTO tblProductDetails VALUES (2, 'DEF', 2)INSERT INTO tblProductDetails VALUES (3, 'GHI', 3)INSERT INTO tblProductDetails VALUES (4, 'GHI2', 3)INSERT INTO tblProductDetails VALUES (5, 'GHI3', 3)INSERT INTO tblProductDetails VALUES (6, 'JKL2', 4)INSERT INTO tblProductDetails VALUES (7, 'JKL', 4)INSERT INTO tblProductDetails VALUES (8, 'JKL3', 4)INSERT INTO tblProductDetails VALUES (9, 'JKL4', 4)CREATE TABLE [dbo].[tblProductComponents] ([UniqueID] [int] NOT NULL PRIMARY KEY ,[ProductID] int,[Component] [varchar] (80) NULL) ON [PRIMARY]GOINSERT INTO tblProductComponents VALUES (1, 1, 'ABCa')INSERT INTO tblProductComponents VALUES (2, 1, 'ABCb')INSERT INTO tblProductComponents VALUES (3, 1, 'ABCc')INSERT INTO tblProductComponents VALUES (4, 2, 'DEFa')INSERT INTO tblProductComponents VALUES (5, 2, 'DEFb')INSERT INTO tblProductComponents VALUES (6, 2, 'DEFc')INSERT INTO tblProductComponents VALUES (7, 2, 'DEFd')INSERT INTO tblProductComponents VALUES (8, 3, 'GHIa')INSERT INTO tblProductComponents VALUES (9, 4, 'JKLa')INSERT INTO tblProductComponents VALUES (10, 4, 'JKLb')CREATE TABLE [dbo].[tblProductComponentsResult] ([UniqueID] [int] NOT NULL PRIMARY KEY ,[ProductID] int,[Component] [varchar] (80) NULL) ON [PRIMARY]GOINSERT INTO tblProductComponentsResult VALUES (1, 1, 'ABCa')INSERT INTO tblProductComponentsResult VALUES (2, 1, 'ABCb')INSERT INTO tblProductComponentsResult VALUES (3, 1, 'ABCc')INSERT INTO tblProductComponentsResult VALUES (4, 2, 'DEFa')INSERT INTO tblProductComponentsResult VALUES (5, 2, 'DEFb')INSERT INTO tblProductComponentsResult VALUES (6, 2, 'DEFc')INSERT INTO tblProductComponentsResult VALUES (7, 2, 'DEFd')INSERT INTO tblProductComponentsResult VALUES (8, 3, 'GHIa')INSERT INTO tblProductComponentsResult VALUES (9, 4, 'JKLa')INSERT INTO tblProductComponentsResult VALUES (10, 4, 'JKLb')INSERT INTO tblProductComponentsResult VALUES (11, 5, 'GHIa')INSERT INTO tblProductComponentsResult VALUES (12, 6, 'GHIa')INSERT INTO tblProductComponentsResult VALUES (13, 7, 'JKLa')INSERT INTO tblProductComponentsResult VALUES (14, 7, 'JKLb')INSERT INTO tblProductComponentsResult VALUES (15, 8, 'JKLa')INSERT INTO tblProductComponentsResult VALUES (16, 8, 'JKLb')INSERT INTO tblProductComponentsResult VALUES (17, 9, 'JKLa')INSERT INTO tblProductComponentsResult VALUES (18, 9, 'JKLb')CREATE TABLE [dbo].[tblProductsResult] ([UniqueID] [int] NOT NULL PRIMARY KEY ,[Name] [varchar] (80) NULL,[TagNo] [int] NULL) ON [PRIMARY]GOINSERT INTO tblProductsResult VALUES (1, 'ABC1', 55)INSERT INTO tblProductsResult VALUES (2, 'DEF', 66)INSERT INTO tblProductsResult VALUES (3, 'GHI', 77)INSERT INTO tblProductsResult VALUES (4, 'JKL', 88)INSERT INTO tblProductsResult VALUES (5, 'GHI2', 77)INSERT INTO tblProductsResult VALUES (6, 'GHI3', 77)INSERT INTO tblProductsResult VALUES (7, 'JKL2', 88)INSERT INTO tblProductsResult VALUES (8, 'JKL3', 88)INSERT INTO tblProductsResult VALUES (9, 'JKL4', 88)I appreciate your assistance on this.Thank you very much
Just wondering if anyone is aware of a SQL server shareware utility that places a front end on a table to manage insert, update, and delete of rows on a lookup table.
We can certainly write this but before reinventing the wheel I figure I'd ask and see.
A problem has come up in designing a Web page to maintain a small reference table in SQL Server 2000 (9 columns, about 25 records).
I tried to design the Web page to allow INSERT and UPDATE operations using a single page that posts back to itself. The page contains a set of empty form fields for a new record, followed by a set of filled-in form field for each row in the table. The form fields for existing records are given a unique name based on the field name concatenated with the primary key value for that row.
If I set up the page to INSERT only, it works properly. But when I add the fields for existing records, the INSERT operation malfunctions. Specifically, anytime a set of existing fields for a particular column is added to the page, the INSERT will no longer work properly for that column. This is true for all fields except the primary key field. It always INSERTs correctly. I tried adding only some columns to the set of existing form fields. In that case, the INSERT operation added the correct values for the fields that were not listed in the existing records section, but failed for the others.
I am using the INSERT INTO syntax for that operation and the recordset .Update syntax for the edits. I tried using the recordset .AddNew/.Update syntax for the insert, but it exhibited the same problems. The column data types contain smallint, bit, nvarchar, and ntext types.
I know that the correct values are being put into the INSERT statement. I also tried renaming the INSERT form fields to be totally different than the names of the existing record fields. But the problem comes back no matter what.
If necessary, I can split the logic so that inserts and updates are handled by different pages. But I would like to make this work if possible. If a reader knows why SQL Server is causing this problem, any help would be greatly appreciated.

Given a simple spreadsheet:
StoreNumber StoreName
1 UPDStoreName_1
2 UPDStoreName_2
3 UPDStoreName_3
4 NEWStoreName_4
I want to have an SSIS package that will update a table: mystores (storenumber int, storename nvarchar(255))
StoreNumber StoreName
1 StoreName_1
2 StoreName_2
3 StoreName_3
5 StoreName_5
.. what I need to do is insert the new, update the existing and leave the remaining unchanged. i.e. :
StoreNumber StoreName
1 UPDStoreName_1
2 UPDStoreName_2
3 UPDStoreName_3
4 NEWStoreName_4
5 StoreName_5
(the UPD and NEW are added to simplify the example).
Now the default action of an excel source into an ole db destination is an insert into the table - so PK constraints causes failures.
Now, given that the table is referred to by other table, and is in a 24x7 website, how do I change the SSIS package such that, on a row-by-row basis, anUpSert (update or insert) is performed?
The only idea I have so far is:
create temp table
insert excel data into temp table
iterate through the table, using if exists ... update else insert logic <-- this to be done in a SP

I want to be able to duplicate every single record that is inserted or updated in a particular table to another table, but not the delete. Is the best way to set-up a trigger? If so can anyone provide me with an example of how to do this? Also could you just duplicate certain columns in the row I would you have to do all columns?
I'm trying to update (increment) Company.SumtotalLogons from CompanyUsers.NumberOfLogons where CompanyUsers.CompanyID = Company.CompanyID
I'd like to either write a formula (if it is even possible to fire a formula from one table update/insert to increment a field in another table), or a stored procedure that triggers an auto update/append into Company.SumTotalLogons
I know this is possible in access, so i'm wondering how to go about it in ms-sql?
Is it possible to allow a user to insert and update data in a table but prevent them from performing deletes against that same table? For auditing purposes I need to prevent the end users from being able to delete data.
We have a database on a 2005 box, which we need to keep in sync with one on a 2014 box (until we can turn off the one on 2005). The 2005 database is still being updated with changes that must be applied to the 2014 database, given the nature of the data (medical documents) we need to ensure updates are applied to the 2014 database in very near real time (these changes are - for example - statuses, not the documents themselves).
Cunning plan #1, ulgy - not at all a fan of triggers - but use an after update trigger to run a sp on the remote box via a linked server in this format, with a SQL Server login for the linked server with permissions to EXEC the remote proc.
CREATE TRIGGER [dbo].[SourceUpdate] ON [dbo].[SourceTable] AFTER UPDATE AS SET XACT_ABORT ON; SET NOCOUNT ON; IF UPDATE(ColumnName)
[Code] ....
However, while the sp can be run against the linked server as a standalone query OK, when running it in a trigger it's throwing
OLE DB provider "SQLNCLI" for linked server "WIBBLE" returned message "The transaction manager has disabled its support for remote/network transactions.".
Msg 7391, Level 16, State 2, Procedure TheAfterUpdateTrigger, Line 19
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "WIBBLE" was unable to begin a distributed transaction.
Whether it actually possible to call a proc on a remote box via a trigger and if so what additional hoops need to be jumped through (like I said, it'll run OK called via SSMS)?
