We are using push subscription using transactional replication. Is there a recommended value for retention period on distributionDb? We are using default value of 72 hrs and recently we saw an issue where data was not replicated with an error that subscription was inactive. When I searched, I fid that it is related to the retention period setting on distribution DB.
I have a scenario where I need to add a blank column to a table that is a publisher. This table contains over 100 million records. What is the best way to add the column? In the past where I had to make an update, it breaks replication because the update would take forever as jobs are continuously updating the table so replication can't catch up.
If I alter a table and add a column, would this column automatically get picked up in replication?
Is there a script to find which non-clustered indices are replicated? I know i can do this easily through GUI , having a script will make my life much easier ....
In our environment (SQL 2005) we have a database that uses Transactional Replication to sync data between two SQL 2005 servers. There is a web app that reads/writes data to the publisher server and the other server (that gets the replicated data) is used by some other internal applications.
At times, there is a need to delete some data from the publisher server...but this can ONLY happen once the data has been successfully replicated to the second server. Is there any way to determine if a row has been replicated successfully?
I have an application that uses web-based merge replication. My publisher is SQL 2005 and my subscriber is SQL 2005 Express. I control the replication with RMO code. If I make changes to the data in both databases using SQL Server Management Studio Express, my RMO code correctly syncs the two databases. However if I make changes to the data at the subscription through my application, these changes are not picked up by the replication process, even though the changes are present if you check the tables through Management Studio. What would cause these changes to not be recognized? Any ideas would be appreciated.
Dear All, i've one database replicated from production server. now i need to change one perticular table column datatype. what steps i need to follow to do this?
thankyou very much

Hello AllI was wondering if there's a way to monitor/measure data-transferbeing taking place between 2 serves in a replicated environment.I cannot see any counters, etc. to monitor this..??thanksSunit
Is there somewhere that I can tell when the last time either the publication or better yet a subscrition replicated data (in a system table or view maybe)??
I want to set up monitoring to make sure I am aware if something for some reason does not replicate
How would I best go about changing a published table's column from smallint to int? I could not find anything about it in BOL or MS.com. I do not think EM/Replication Properties allows the change. I suspect I have to run "Alter Table/Column" on the Publisher and each Subscriber the old-fashioned way. Is that true?
We have a master database (SQL 2014 Std) from which data are imported from XML files (send by en ERP system) using SSIS. There is about 12 other servers (SQL 2014 Express) located in remote warehouses. People will uses PocketPC to scan barcode of products in the warehouses and all operations must be forwarded to the master DB to be exported in a XML file for the ERP system.Now, each warehouses are independant. How can I setup the replication so only data belonging to a specific warehouse is replicated to its corresponding DB? I thought about creating views, one for each warehouses, and setup a replication for each warehouse, so there would be 12 merge replications configured. Is it fine?
I need to create a function that replaces the data in a column with an 'X' based on the LEN of the data in the column. I created one that does a replacement, but it fills the column based on the max data length, and not the current length of the string or integer. An example of what I'm trying to accomplish.
Original data in a varchar(30) column: thisisavalue thisisanothervalue thisisanothervalueagain shortval
replaced with xxxxxxxxxx xxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx xxxxxxx
My current function is replacing the data like this: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
1) Are there any "hooks" available to insert processing when a subscriber is about to copy data from a replicating site?
2) Is it possible for a subscriber to change only his local copy of the data - without replicating the changes back to the publisher?
I realise that once the data changes in one place it isn't really replicated anymore, and I realise that my limited knowledge of the subject might well mean I'm not even asking the right questions. Therefore, I shall try to describe as best I can my scenario.
I wish to use many servers for transactional input (to distribute the workload) and use replication to publish the inputted data to a subscribing central site. One of the tables I wish to replicate has an identity column as primary key, but the records should otherwise be unique - i.e. no two records should differ only in the value of the key. Another table, which should also be replicated, uses this id value as a foreign key.
I can use the identity increment and seed to guarantee no key violations will occur when copying data to the central server. However, there is another issue: Several servers can create the same record but with different id values.
I need to "merge" such records by deleting duplicate entries in the table with the identifier as primary key, and update the foreign keys correspondingly. To clarify (I hope!), here's an example of what data I might have on the central site after copying data from two input sites:
TRANSACTION table
amount = 200, metadata_id = 1001 // Replicated from server INPUT_1
amount = -117, metadata_id = 2001 // Replicated from server INPUT_2
METADATA table:
id=1001 Actitiy=Sales, Country=USA
id=2001 Activity=Sales, Country=USA
What I would like is basically for the central site to identify that metadata 2001 is really the same as metadata 1001, update the foreign key in the TRANSACTION record accordingly and not import (or delete, if this "merging" is done in a post-treatment) the duplicate metadata record.
If anyone can offer any advice on how to achieve this I would appreciate your input.
1) I can't get the 'copy database' function to work from SQL Server 2008 to SQL Server 2005. I connect ok. Everything goes to the last step and then it fails.2) I cant get a SQL server 2008 backup to restore on SQL SEerver 2005 either. The only way I know that works is to script the creation of all tables then export and import. This does work. How can I get the 'entire' database, structure and data, from 2008 to 2005? ThanksSQL newbie.
Production and development servers are on different domains and they do not trust each other. How do I import data from the table t1 from a database db1 in production and load it into table t1 inside database db1 in development?
I have the linked server connection created and works perfectly well. I mean I am able to see the tables while I am on my database.
how do I write a SQL statement to reference the linked server ?
I tried the following:
Select top 100 * from casmpogdbspr1.MPOG_Collations.dbo.AsaClass_Cleaned
Then I get the error message....
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "SQLNCLI10" for linked server "casmpogdbspr1" does not contain the table ""MPOG_Collations"."dbo"."AsaClass_Cleaned"". The table either does not exist or the current user does not have permissions on that table.
I am task with identifying the source database name, id, and server name for each staging table that I create. I need to add this to a derived column on all staging tables created from merging same tables on different servers together.
When doing a Merge Join, there is no way to identify the source of data so I would like to see if data came from one database more than the other servers or if their are duplicates across servers.
The thing that bugs me about SSIS Data Flow task is there is no way to do an easy Execute SQL Task after I select my ADO.NET Source to get this information because my connection string is dynamic and there is no way of know which data source is being picked up at runtime.
For Example I have Products table on Server 1 and 2:
Server 2 has more Products and would like to join the two together to create a staging table.
I have a report that summarizes hospital readmissions. Some months may only have a female or male patient that is readmitted but, I want to show both months either way.
And I always know the root ID from the first record on "table" dummy (generated with a common table expression), in this case it's ID 1, but from here, how to process this for any level of depth ?
We have this query that pulls number of days worked from the current Quarter to Date.
(SELECT COUNT(DISTINCT daysworked) AS 'Days Worked' FROM (SELECT CAST(DATEPART(MM, DATEADD(HOUR, -8, ActualEnd)) AS VARCHAR) + '/' + CAST(DATEPART(DD, DATEADD(HOUR, -8, ActualEnd)) AS VARCHAR) + '/' + CAST(DATEPART(YYYY, DATEADD(HOUR, -8,ActualEnd)) AS VARCHAR) AS daysworked, ActivityId AS totalcalls FROM PhoneCall AS p WHERE (DATEPART(QUARTER, DATEADD(HOUR, - 8, ActualEnd)) = DATEPART(QUARTER, DATEADD(QUARTER, -1, GETDATE()))) AND (DATEPART(YEAR, DATEADD(HOUR, - 8, ActualEnd)) = DATEPART(YEAR, DATEADD(QUARTER, -1, GETDATE()))) AND (OwnerId = x.SystemUserId)) AS tb) AS [Days Worked],
I need changing it to bring up LAST Quarter's data.
It might be an old question but wanted to see, if we have any latest techniques (other than bcp).
SELECT Field1, Field2 FROM MyTable
If I want to export the output of the above query to a csv on a network folder? I would like to avoid usage of SSIS package or BCP (as user needs to get additional rights to execute bcp).
There are some more columns with more 'nvarchar' (max) and other INT data types. Anyway, I know a page is 8K size. How do I find out how much space does A ROW takes with above datatypes? If users add 5000 Rows per day, how do I figure out how much size the table will increase?
I'm looking for a process to archive data through replication. I have nightly job that purge records in few source tables(publisher) retaining only 3 yrs data. I have archive database (subscriber) that contains prior 3 yrs data and current 3 yrs data.
Before nightly job DELETES records in Source table i want to STOP replication so that the delete is not replicated in archive database. After the job completes i would like to TURN ON replication so that any new inserts and updates in Source will ONLY be replicated in archive database.
My DBA tested this but after last step of turning replication back ON archive database is sync'd with source table.
There are around 70 tables where 30 of them are transactional tables that needs record purge. Developing ETL process is possible but tedious.
Using below statement to export a table from sql server 2008 to EXCEL 2010
Insert into Openrowset ('Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C:ExportXLS.xlsx;' , 'SELECT * FROM [employees$]') SELECT name,id,group,agency FROM dbo.employees
getting below ERROR
OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries because the provider is configured to run in single-threaded apartment mode.
below changes also done. sp_configure 'show advanced options', 1; GO RECONFIGURE; GO sp_configure 'Ad Hoc Distributed Queries', 1; GO RECONFIGURE; GO
parent | NAme | Checked | contactmethod|Check2 | Other 974198 | Employment | true | Face to Face | true | null 974224 | Other | true | Face to Face | true | skills 974224 | Other | true | Contact | true | skills
I'd like to pivot on "parent"
In a perfect world I'd like to see output like
974198 | Employment | true | Face to Face | true | null
974224 | Other | true | Face to Face, Collateral Contact | true | skills
If there are more than one name or contactmethod for the same parent then they would be strung along with commas
I need to update the Denominator column in one row with the value from the Numerator column in a different row. For example the last row in the table is
c010A92NULL
I need to update the Denominator, which is currently NULL, with the value from the Numerator where the MeasureID=c001 and GroupID=A.
I am using MS SQL 2008, and I am trying to extract data from a MySQL database. I am having trouble extracting the data I need.
In SQL Server management studio, I can see the linked server...I can browse the different databases on the server. I can see user and system tables in all of the databases.
When I try and query a linked table (select * from server.db.table) I get Invalid object name 'servername.databasename.tablename'.
When I try script the table.. right_click on the linked table, Script table as, Select to, New Query Editor window, I get an error '[servername].[databasename]..[tablename] contains no columns that can be selected or the current user does not have permissions on that object.'
This leads me to believe that it is a permissions problem, but if I have access to the MySQL database using MySQL and the same login/password) and can retrieve the data there, then I think my login credentials should be enough using MS SQL. I guess I think its odd that I could have enough credentials to get in and see table names, but not do a select against it.
I am writing a query to return some production data. Basically i need to insert either 1 or 2 rows into a Table variable based on a decision as to does the production part make 1 or 2 items ( The Raw data does not allow for this it comes from a look up in my database)
I can retrieve all the source data i need easily but when i come to insert it into the table variable i need to insert 1 record if its a single part or 2 records if its a twin part. I know could use a cursor but im sure there has to be an easier way !
Below is the code i have at the moment
declare @startdate as datetime declare @enddate as datetime declare @Line as Integer DECLARE @count INT
set @startdate = '2015-01-01' set @enddate = '2015-01-31'
