Transform MySQL Queries

This package provides functions for transforming MySQL queries. Most important is query.Fingerprint:

package main

import (
    "fmt"
    "github.com/go-mysql/query"
)

func main() {
    f := query.Fingerprint(
        "SELECT c FROM t WHERE id IN (1,2,3) AND ts < '2017-01-01 00:00:00'",
    )
    fmt.Println(f)
}

Output: select c from t where id in(?+) and ts < ?

That fingerprint can be transformed into a unique ID:

id := query.Id(f) // return "EA2376FD2AFF00BA"

Fingerprints and IDs are used to parse and aggregate queries from the MySQL slow log.
