Convert the given numbers into words in Pl/SQL
Prerequisite – PL/SQL introduction
In PL/SQL code groups of commands are arranged within a block. A block group related declarations or statements. In declare part, we declare variables and between begin and end part, we perform the operations.
Given a number and task is to convert each digit of the number into words.
Examples:
Input: 47856 Output: Four Seven Eight Five Six Input: 123456 Output: one two three four five six
Approach is to select the corresponding word of a particular number using decode function.
Below is the required implementation:
DECLARE -- declare variable are num, num_to_word, str, len, c -- and in above declare variable num, len, c are integer datatype -- and num_to_word and str are varchar datatype num INTEGER; num_to_word VARCHAR2(100); str VARCHAR2(100); len INTEGER; c INTEGER; BEGIN num := 123456; len := Length(num); dbms_output.Put_line('Entered Number is: ' ||num); FOR i IN 1..len LOOP c := Substr(num, i, 1); SELECT Decode(c, 0, 'Zero ', 1, 'One ', 2, 'Two ', 3, 'Three ', 4, 'Four ', 5, 'Five ', 6, 'Six ', 7, 'Seven ', 8, 'Eight ', 9, 'Nine ') INTO str FROM dual; num_to_word := num_to_word ||str; END LOOP; dbms_output.Put_line('Number to words: ' ||num_to_word); END; -- Program End |
Output :
Entered Number is: 123456 Number to words: One Two Three Four Five Six
