Set all databases to the Full recovery model:

/*--------------------------------------------------------------------------------

Sometimes it is necessary to change properties of all your databases in one shot

In this script, we use a system table to get all the database names on our server.

Then we use a cursor to loop through all the records and then change the recovery
model using Alter Database command.

@dbnm sysname,
@sql varchar(100)


-- Declare begin cursor to get the database names and get info from sys.databases catalog

declare cursor_db cursor
