Talk about sparse details. It would be helpful if in the future you could provide more details. At the very least declare the variables.

Once I declared the variables so I could start looking it was pretty obvious.

declare @OrgName varchar(max), @OrgID int, @dbname varchar(50)

Then just start removing stuff from your code to isolate the issue.

The culprit is here.

CONVERT(varchar(20),+ 'pol_id)'

That will get rid of the syntax error but...

Actually this script is a part of my program that uses cursors concept

Cursors are horribly slow and should be used in certain situations. I can't tell from your snippet but I doubt that what you doing here is one of those situations. If you want to really improve your code, take a look at the first link in my signature about best practices, post ddl and sample data along with desired output and we can help you get rid of that nasty cursor.
