## Ejemplo
|
|
|
|
```go
|
|
db, err := ClickHouseOpen("localhost", 9000, "default", "", "analytics")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
defer DBClose(db)
|
|
|
|
rows, err := DBQuery(db, "SELECT event, count() FROM events GROUP BY event")
|
|
```
|
|
|
|
## Notas
|
|
|
|
Usa el driver `github.com/ClickHouse/clickhouse-go/v2` registrado como "clickhouse". Puerto por defecto de ClickHouse es 9000 (nativo) o 8123 (HTTP). Hace ping al abrir para verificar conectividad.
