Are you looking at the on-line docs on our web site or the local docs within the product help?
If you are looking on-line then they will be the docs for the 2.3 product. If you look under Welcome-->New features you will see that the Cobsql integration was added to the SQL properties age starting with V2.3.
If you are using 2.2 you will not have this feature and will have to upgrade to 2.3.
Thanks
