DB2 has three main security mechanisms to help DBAs implement database security plans:
Authentication, authorization, and privilege ).
Five different permission levels: sysadm, sysctrl, sysmaint, dbadm, and load
A new concept in DB2 9 is tag-based access control (lbac) that allows control of who has the right to access individual rows and/or columns.

The timestamp (), date (), and time () functions support more formats. The above formats are just examples. I will use them as an exercise so that readers can discover other formats themselves.
Sometimes, you need to know the time difference between two timestamps. Therefore, DB2 provides a built-in func

appropriately. Conversely, when the input parameter is numeric, the function assumes that the value of this parameter is equal to the number of days from the first day of the current year (0001-01-01. In the above example, our input is, which is interpreted as (2001-9)-22, equal to 1970 days. Therefore, this function is interpreted as DATE (1970 ). Sometimes, you need to know the time difference between two timestamps. Therefore, DB2 provides a built
