Dear Sir/Madam,
Suppose I have an input string "abc,efg,hijk", I want to count how many commas are included in the string (in this example, I want to return 2 since there are 2 commas). I searched around but found nothing. There is a similar post with no solution: https://developer.salesforce.com/forums/?id=906F0000000D8qKIAS

Thank you for the help.
