In PL/SQL, an error condition is called anexception. Exceptions can be internally defined (by the runtime system) or user defined. Examples of internally defined exceptions includedivision by zeroandout of memory. Some common internal exceptions have predefined names, such asZERO_DIVIDEandSTORAGE_...

possible. Aggregate expressions that appear in WHEN arguments to aCASEexpression are evaluated first, then provided to theCASEexpression. For example, the following query produces a divide by zero error when producing the value of the MAX aggregate. This occurs prior to evaluating theCASEexpression....
