 etc will not be parsed.  Consequently you may have portability issues
 if you write a query like this:
 
-```go // works on MySQL and Sqlite3, but not with Postgresql err :=
-dbmap.SelectOne(&val, "select * from foo where id = ?", 30) ```

 In `Select` and `SelectOne` you can use named parameters to work
 around this.  The following is portable:
 
-```go err := dbmap.SelectOne(&val, "select * from foo where id = :id",
-map[string]interface{} { "id": 30}) ```
+```go
