Using LIMIT
For nested tables, that have no maximum size, the LIMIT returns NULL. For varrays, the LIMIT returns the maximum number of elements that a varray can have (that you must specify in its type definition). For illustration, when the maximum size of varray projects is 25 elements, then the IF condition below is true:
IF projects.LIMIT = 25 THEN...
You can use LIMIT where an integer expression is allowed. In the illustration below, you use LIMIT to determine if you can add 20 more elements to the varray projects:
IF (projects.COUNT + 20) < projects.LIMIT THEN...
