import "strconv"
// A handy little helper function for building queries. Appends 'value'
// to the 'args' slice and returns a string '$N' referring to the index
// of the value in args. For example:
//
// var args []interface{}
// query = "select * from foo where id=" + nextBindVar(&args, 100)
// db.Query(query, args...)
func nextBindVar(args *[]interface{}, value interface{}) string {
*args = append(*args, value)
return "$" + strconv.Itoa(len(*args))
}
