String Manipulation

String Manipulation

  • CONCAT <variable_1> AND <variable_2> TO <new_variable>: Merge two strings.
  • REPLACE <old_string> WITH <new_string> IN <variable>: Replace specific portions of a string.

Example - String Manipulation

  1. Concatenating Strings: Let's say you have two variables, var1 with the value "Hello" and var2 with the value "World". You want to concatenate them with a space in between.

    CONCAT var1 AND " " AND var2 TO greeting
    
    After executing the above, the greeting variable will have the value "Hello World".

  2. Replacing Strings: Consider a variable message with the value "I love apples". You want to replace "apples" with "oranges".

    REPLACE "apples" WITH "oranges" IN message
    
    After this operation, the message variable will have the value "I love oranges".

  3. Extracting Strings: (Note: Assuming Flux supports an EXTRACT command for the sake of this example) If you have a variable sentence with the value "The quick brown fox", and you want to extract the word "quick".

    EXTRACT "quick" FROM sentence TO extractedWord
    
    The extractedWord variable will now hold the value "quick".
