SQL::Tokenizer - A simple SQL tokenizer.

       •   Evan Harris, for implementing Shell comment style and SQL operators.

       •   Charlie Hills, for spotting a lot of important issues I haven't thought.

       •   Jonas Kramer, for fixing MySQL quoted strings and treating dot as punctuation character correctly.

       •   Emanuele Zeppieri, for asking to fix SQL::Tokenizer to support dollars as well.

       •   Nigel Metheringham, for extending the dollar signal support.

       •   Devin Withers, for making it not choke on CR+LF in comments.

       •   Luc Lanthier, for simplifying the regex and make it not choke on backslashes.

       tokenize_sql
            use SQL::Tokenizer qw(tokenize_sql);

            my @tokens= tokenize_sql($query);
            my $tokens= tokenize_sql($query);

            $tokens= tokenize_sql( $query, $remove_white_tokens );

           "tokenize_sql"  can be imported to current namespace on request. It receives a SQL query, and returns
           an array of tokens if called in list context, or an arrayref if called in scalar context.

       tokenize
            my @tokens= SQL::Tokenizer->tokenize($query);
            my $tokens= SQL::Tokenizer->tokenize($query);

            $tokens= SQL::Tokenizer->tokenize( $query, $remove_white_tokens );

           This is the only available class method. It receives a SQL query, and returns an array of  tokens  if
           called in list context, or an arrayref if called in scalar context.

           If $remove_white_tokens is true, white spaces only tokens will be removed from result.

       SQL::Tokenizer is a simple tokenizer for SQL queries. It does not claim to be a parser or query verifier.
       It just creates sane tokens from a valid SQL query.

       It supports SQL with comments like:

        -- This query is used to insert a message into
        -- logs table
        INSERT INTO log (application, message) VALUES (?, ?)

       Also supports '', "" and "\'" escaping methods, so tokenizing queries like the one below should not be a
       problem:

        INSERT INTO log (application, message)
        VALUES ('myapp', 'Hey, this is a ''single quoted string''!')

       SQL::Tokenizer - A simple SQL tokenizer.

        use SQL::Tokenizer qw(tokenize_sql);

        my $query= q{SELECT 1 + 1};
        my @tokens= SQL::Tokenizer->tokenize($query);

        # @tokens now contains ('SELECT', ' ', '1', ' ', '+', ' ', '1')

        @tokens= tokenize_sql($query); # procedural interface
