    In this session , when we use Instr for emp table like … let’s consider
    Query:- Select INSTR(‘ANDREAS’ , ‘a’,1,1) from dual ;
    It return 0 Because that ‘a’ is case sensitive that’s why not counting if we give ‘A’ then it will take count and return 1.
    In Mayank name a is small letter that’s why taking 1st occurrence is at 2nd position that’s why return 2
    Correct me if I am wrong

    • @etlqalabs5048
      @etlqalabs5048  3 ปีที่แล้ว +2

      That's right . It’s case sensitive and when it doesn’t find the match it returns the 0

    Simply do =>
    Select SUBSTR(‘Mayank’,2,1) || SUBSTR(‘Mayank’,4,1) from Dual ;
    Result :- aa
    U can also try on actual table
    Select SUBSTR (ename,2,1) || SUBSTR (ename,4,1) from employees;
    Result for Mayank is => aa

      Yes this is static solution and generally not a practical requirement . You generally need a solution that works for a variety of data within that column hence I have used instr function to locate the occurrence of 2 occurrence and extracted . So query may like this - find all the values in ename who are having 2 or more a’s . Just an example . Hope this clarifies
