For a free comparison tool, you could look at this one:

If you don't mind paying or using a trial version, the Red Gate SQLCompare tool is excellent and well worth the money:

Solution 2

Run a query on each that returns the table structure:

SQL

SELECT column_name, data_type, is_nullable, character_maximum_length FROM information_schema.COLUMNS WHERE table_name='myTable'

If the two queries return the same data, the tables are effectively the same.

This will work for a simple column compare but it won't get things like indexes, triggers, keys, or other items that are attached to the table.

Solution 5

Following query will selects only matching columns in two different tables.

SQL

select distinct column_name ,data_type,is_nullable, character_maximum_length
FROM information_schema.COLUMNS
WHERE table_name='TableName1' OR  table_name = 'TableName2'
GROUP BY column_name,data_type,is_nullable, character_maximum_length  HAVING COUNT(*)>1

Reason for downvote...question is over a year old, already answered and your solution does not solve the OPs problem

Ok, No problem. I was looking for to find identical column in two different database tables.
I just got hint from this Discussion. I just posted my questions solution here.
Thanks
