Answer / rajesh venati

1. Procedures are used to perform a particular task.
2. Procedures may or may not return a value, if u want
return a value though the OUT parameter it is possible. It
doesn't contain any RETURN key word.
3. Procedures are not valid in SELECT statement.

1. Functions are used for computation purpose.
2. Function must and should be return a value.
3. We can execute function in a SELECT statement.
-- If u use OUT or IN OUT parameters or perform any DML
operations on functions it is not valid in SELECT statement.
