MS SQL Get Table Row With Data

Question

I have two seperate database with the same table structure but with different data. My database "a" got a table named articles with the columns of id, heading, detail and date. Database "b" also got the identical table.

For example:

a database has 10 rows.

b database has 12 rows.

Is there anyway to get the 3 selected row from a and transfer it to the b with the data that rows hold.

Answer 1

One reasonable interpretation of the question is that you want to move rows from a.dbo.articles to b.dbo.articles that are not already there:

insert into b.dbo.articles(id, heading, detail, date)
    select id, heading, detail, date
    from a.dbo.articles a
    where not exists (select 1 from  b.dbo.articles b where b.id = a.id);

Notes:

• This assumes that the two databases are on the same server. Otherwise, you need a database link.
• This assumes that the id is sufficient for the comparison. If not, just add the right logic to the where clause.
