PL/SQL Block The above statement is true. The declaration and exception blocks are optional in PL/SQL block. The basic program unit in PL/SQL is the block. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords partition the block into a declarative part, an executable part, and an exception-handling part. Only the executable part is required. You can nest a block within another block wherever you can place an executable statement. Prajakta Pandit 02-15-2017 01:53 AM
