/**
* Resolves the ambiguity when dealing with the "*" operator.
*
* In SQL statements, the "*" operator can be an arithmetic operator (like in 2*3) or an SQL wildcard (like in
* SELECT a.* FROM ...). To solve this ambiguity, the solution is to find the next token, excluding whitespaces and
* comments, right after the "*" position. The "*" is for sure an SQL wildcard if the next token found is any of:
* - "FROM" (the FROM keyword like in "SELECT * FROM...");
* - "USING" (the USING keyword like in "DELETE table_name.* USING...");
* - "," (a comma separator like in "SELECT *, field FROM...");
* - ")" (a closing parenthesis like in "COUNT(*)").
* This methods will change the flag of the "*" tokens when any of those condition above is true. Otherwise, the
* default flag (arithmetic) will be kept.
*
* @return void
