User would like to copy the data from one table into another table.
You can use Generate Data Script. Right click on database node and select Generate Data Script. In Generate Data Script select desired object and press Build script. Script with data will be generated. Modify the script as needed.
An enhancement request has been submitted to the development team to be able to right click on the table instead of the database and access the Generate Data Script. This will be in concideration in a future release of Toad for SQL Server.
