Tabli - How to create a table from the definition of another table

About

This Howto will show you how to copy the data definition of a SQL table from another SQL table by using the Tabli table create command.

This command does not copy the data. It just create the structure (ie it performs a SQL CREATE statement). If you want to copy the data, use the tabli data transfer command instead.
