It is important to use the type varChar for the name @tab_name since its content is concatenated with some SQL command to truncate tables.

In order to divide two integer type fields in SQL Server you will have to apply a type cast before applying the mathematical operation.

Else you will receive zero (0) as a result whenever one of the numbers is not null, which is obviously not what we want.
