Overview

Package qblogz provides a sqlmw driver interceptor that logs to a qblog Logger (see http://github.com/ngrok/sqlmw).

Example

// Log goes to os.Stderr, not os.Stdout. It has time info, i.e. we don't
// want it in 'Output:'. Otherwise one would see something like:
//
//   Oct 03 16:55:31.990 INFO  [example] `conn:1` `exec…:CREATE TABLE example (id integer PRIMARY KEY, name text NOT NULL)` with `args:[]`
//   Oct 03 16:55:31.990 INFO  [example] `conn:1` `…exec:91.529µs` with `err:<nil>`
log := qblog.New("example")
sql.Register("log/sqlite3", sqlmw.Driver(
	&sqlite3.SQLiteDriver{},
	Logger{Log: log, Level: c4hgol.Info},
))
db, _ := sql.Open("log/sqlite3", ":memory:")
defer db.Close()
_, err := db.Exec(`CREATE TABLE example (id integer PRIMARY KEY, name text NOT NULL)`)
fmt.Println(err)

Output:

<nil>
