FAST version of PARSECOUNT function working on scalar string variable only!
Return the count of delimited (sub) fields in a string expression.
n = PARSECOUNTF(StringVariable, [ANY] StringSelimiter)
IMPORTANT: a scalar string variable.
The string to be parsed.
If StringVariable is empty or contains no delimiter character(s), the string is considered to contain exactly one field. In this case, PARSECOUNT returns 1.
Contains delimiter character(s). A delimiter is a character, list of characters, or string, that is used to mark the end of a field in MainString.
If the ANY is used, StringVariable contains a set of characters, any of which may act as a delimiter character. If the ANY keyword is omitted, the entire StringVariable string acts as a single delimiter. Delimiters are case-sensitive.
If StringVariable is an empty string, special rules apply. The delimiter is assumed to be a comma. Fields may optionally be enclosed in quotes. Such quotes are considered as special field delimiters and are not returned as part of the result string. Any characters that appear between a quote mark and the next comma delimiter character are discarded. If no leading quote is found, any leading or trailing spaces are trimmed before the result string is returned.
