When a variable is created in SQL with the declare statement it is created with no data and stored in the variable table (vtable) inside SQLs memory space. The vtable contains the name and memory address of the variable. However, when the variable is created no memory address is allocated to the variable and thus the variable is not defined in terms of memory.

Hi,

Out of confusion aroused with the above two statements (highlighted )contradicting. Can any one explain them.
