MySQL Wildcards * and %

What is the difference between % and * wildcards in MySQL?

In a query like so : "SELECT * FROM $table WHERE MATCH (message) AGAINST('$string*' IN BOOLEAN MODE)"

"An asterisk is the truncation operator. Unlike the other operators, it is appended to the word, or fragment, not prepended."

This only applies to MATCH() ... AGAINST() statements.

The % is a LIKE wildcard and has nothing to do with the MATCH() ... AGAINST().

I hope that helps.

* can only be used as a wildcard (or truncation) in a full text search while % (match 0 or more characters) and _ (match exactly one character) are only applicable in LIKE-queries.
