    I suggest you check your language settings. It could be influenced if your $LANG variable isn't set correctly. That's a guess, but it might be worth checking. 
  • Hi Curtis,

    now it is working ....

    Sorry problem is -  

    left(<column>, 3)    <column> values are in upper case letters.

    now it is working --- left(lower(<column>),3) in ('abc','xyz')

    I have same tables and values in MySQL and vertica ... but I couldn't checked properly in vertica, the column values are in UPPER case characters. 

    Thank you ...



  • Hello Uday,

    Vertica is a case sensitive search  database.
    It searches data in a case sensitive manner.

    If you want Vertica to be case insensitive while searching then you need to change the locale of the session / database.

    However the above workaround is always suggested while comparing predicates in vertica to values.

    Two Workaround:
    1. User UPPER / LOWER Function on both sides of your predicates

    2. Use locale LEN_S1 for session or database.( This works in some cases only)

    Hope this helps

  • In addtion to navin replay ,#3 is "Ilike" operator which can be in some cases fast then #1 & #2.
