Answer Posted / priya.
Procedures v/s functions.
1.A function MUST return a value. A procedure can also
return value, but it is NOT MANDATORY for Procedure to
return a value.
2.A function can return only ONE value. A procedure can
return MULTIPLE values.
3.A function can be used with SELECT statements as like as
other in-build functions. But, a procedure cannot be used
with SELECT statements.
4.A function cannot be executed directly from SQL prompt
using EXEC command, but it is possible to execute directly
from SQL prompt using EXEC command.
