     # File lib/sequel/sql.rb, line 175
175:       def cast(sql_type)
176:         Cast.new(self, sql_type)
177:       end

Cast the reciever to the given SQL type (or the database‘s default integer type if none given), and return the result as a NumericExpression.

     # File lib/sequel/sql.rb, line 181
181:       def cast_numeric(sql_type = nil)
182:         cast(sql_type || Integer).sql_number
183:       end

Cast the reciever to the given SQL type (or the database‘s default string type if none given), and return the result as a StringExpression, so you can use + directly on the result for SQL string concatenation.

189:         cast(sql_type || String).sql_string
