Question

I want to copy data from one column to another column of other table. How can I do that?

I tried the following:

Update tblindiantime Set CountryName =(Select contacts.BusinessCountry From contacts) 

but it did not work.

I want to copy “BusinessCountry” column of contact table to “CountryName” column of tblindiantime table.

In SQL Server 2008 you can use a multi-table update as follows:

UPDATE tblindiantime 
SET tblindiantime.CountryName = contacts.BusinessCountry
FROM tblindiantime 
JOIN contacts
ON -- join condition here

You need a join condition to specify which row should be updated.

If the target table is currently empty then you should use an INSERT instead:

INSERT INTO tblindiantime (CountryName)
SELECT BusinessCountry FROM contacts
