1. Sql Server Update Table From Another Database

Hi We have employee expenses data entry application in our company. Developed in Dot net with SQL server. Every employee will enter the entry once it is saved, the same data we should write into another SQL database table.

And some instance, based on user choice we need to allow user to modify the data - I have to modify my table - after saving in my table i have do the same update on the other SQL database table. Can you please suggest what is best way to -access other SQL database.

One such i got is: DTS package- to insert to new record. Schedule it for every half hour.

You can also acheive this using MERGE( available in sql 2008 and above). Also, you are referring to DTS. DTS is legacy solution now.are you using sql 2000, you can use ssis, if you want and it available in sql 2005. As said, there are multiple ways you can do this. It find the below one a easy solution, since your are talking about only one table. Try this example. I have not done this in production, but I have done it in my test environment to access tables in different SQL Server.

Sep 07, 2009 How to insert data from one table to another table by using SQL Server There are various ways to insert data from. - The database table to copy.

• I have 2 table in my database. Update table using values from another table in SQL. How can I read data from table #2 and update address and.
• You cannot do UPDATE table1 t SET field1=val, you have to write UPDATE table1 SET field=val (Or UPDATE table1 SET field=val FROM table1 t). So change your query to UPDATE [spdbprod.test.com spprod].[aspnetdb].[dbo].[Communities_Groups] SET Show = t2.show FROM [spdbprod.test.com spprod].[aspnetdb].[dbo].[Communities_Groups] t1 INNER JOIN [spdbQA.test.com spQA].[aspnetdb].[dbo].

Add a linked servers to a remote SQL Server. This example just happens to use a two part table name. Just remove the ' SQL2005' if yours in a one part name. (I think the correct terminology is that the instance name is the same as the server name) USE master GO EXEC spaddlinkedserver 'FIDEV02MP SQL2005', N'SQL Server' GO - verify linked server was added Select. from sys.servers - now try querying a db and table select.

from FIDEV02MP SQL2005.DBNAME.dbo.TABLENAME. You can also acheive this using MERGE( available in sql 2008 and above). Also, you are referring to DTS.

Sql Server Update Table From Another Database

I need to update a table from another one, and I need to update all columns. Besides listing every column in the SET clause, is there a way to update them all at once? Like this: update tableA set. = tableB. from tableB where tableA.id = tableB.id I tried in psql, it doesn't work.

I have to list every column like this: update tableA set c1 = tableB.c1, c2 = tableB.c2. From tableB where tableA.id = tableB.id tableB is created use create.

So they are basically identical. And the reason I'm doing it is that I need to load.csv data to a temp table tableB and then update tableA based on the new data in tableB. TableA needs to be locked as little as possible and tableA needs to keep integrity. I'm not sure 'delete then insert' would be a good option? There is no syntax variant that lets you update the whole row at once. However, there is a shorter form than what you have so far. Also, you do not actually want to update all columns.

The WHERE condition on id pins down at least one column ( id) to remain unchanged. But that's just nitpicking. UPDATE tablea a SET ( c1, c2.) = (b.c1, b.c2.) FROM tableb b WHERE a.id = b.id; More details in this related answer: DELETE / INSERT Internally, due to the, every UPDATE effectively inserts a new row anyway and marks the old one as obsolete. So, behind the curtains there is not much difference between UPDATE and DELETE plus INSERT. There are some details in favor of the UPDATE route:. TOAST tables: If you have large columns, the content may be stored.' Out-of-line' in TOAST tables and the new row version can link to the same row in the TOAST table if toasted columns remain unchanged.

Index maintenance may be cheaper for updates. Otherwise, locking should be about the same. You need an exclusive lock on affected rows either way.

Just make it quick. If you are dealing with a huge number of rows and you don't need a consistent state (all rows or none), you can split the operation into multiple batches. (Separate transactions!) Increases the total cost, but keeps the lock time per row shorter.
