To trace SQL calls to PostgreSQL or MySQL, replacing sql.Open calls to
xray.SQLContext, as shown in the following example. Use URLs instead of configuration
strings if possible.
Example main.go
func main() {
db, err := xray.SQLContext("postgres", "postgres://user:password@host:port/db")
row, err := db.QueryRowContext(ctx, "SELECT 1") // Use as normal
}
