No. of vowels and consonants in a given string in PL/SQL

  • Last Updated : 05 Jul, 2018

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 string and the task is to find the number of vowels and consonants present in the string.
Examples:

Input: str = 'Ramesh'
Output: Vowels = 2, Consonants = 4

Input: str = 'Ramesh is a Geek'
Output: Vowels = 6, Consonants = 7

Approach is to consider a character one by one and maintain a separate count for both vowels and consonants.

Below is the required implementation:




DECLARE 
    -- Here variable V is varchar datatype  
    -- and  flag variable is number datatype   
    -- variable c is char datatype .  
    v              VARCHAR2(400) := 'Ramesh is a Geek'
    noofvowels     NUMBER := 0; 
    noofconsonants NUMBER := 0; 
    C              CHAR
BEGIN 
    FOR i IN 1..Length(v) LOOP 
        c := Substr(v, i, 1); 
  
        -- Check if the current character is vowel 
        IF c IN ( 'A', 'E', 'I', 'O', 'U'
            OR c IN ( 'a', 'e', 'i', 'o', 'u' ) THEN 
          noofvowels := noofvowels + 1; 
  
        -- Else current character is a consonant except space 
        ELSE 
          IF c NOT IN ( ' ' ) THEN 
            noofconsonants := noofconsonants + 1; 
          END IF; 
        END IF; 
    END LOOP; 
  
    dbms_output.Put_line('No. of Vowels: ' 
                         || noofvowels); 
  
    dbms_output.Put_line('No. of Consonants: ' 
                         || noofconsonants); 
END
-- Program End  

Output :

No. of Vowels: 6
No. of Consonants: 7
