The tawny owl or brown owl (Strix aluco) is a stocky, medium-sized owl commonly found in woodlands across much of Eurasia. Its underparts are pale with dark streaks, and the upperparts are either brown or grey. Several of the eleven recognised subspecies have both variants.
At the most basic level, a function definition (i.e., the code that defines the function) requires the function keyword, the function's name, and a script block, as the following syntax shows: The script block, which needs to be enclosed in braces, contains the statements that run when you call the function.
CREATE FUNCTION Statement. The CREATE FUNCTION statement creates or replaces a standalone stored function or a call specification. A standalone stored function is a function (a subprogram that returns a single value) that is stored in the database. A call specification declares a Java method or a third-generation language (3GL) routine so that it can be called from PL/SQL. You can also use the SQL CALL statement to call such a method or routine.
