Here 2 examples of recursive anonymous functions based on previous example. Firstly, simple infinite loop: InfiniteLoop = fun R() -> R() end. Secondly, anonymous function doing loop over list: LoopOverList = fun R([]) -> ok; R([H|T]) -> R(T) end. These two func...

You can execute anonymous block. This example shows also how to return value from dynamic SQL: declare query_text varchar2(1000) := 'begin :P_OUT := cos(:P_IN); end;'; in_value number := 0; out_value number; begin execute immediate query_text using out out_value, in in_value; dbms_o...
