## Ejemplo
|
|
|
|
```go
|
|
rows, err := DBQuery(db, "SELECT id, name, score FROM players WHERE active = ?", true)
|
|
if err != nil {
|
|
return err
|
|
}
|
|
for _, row := range rows {
|
|
fmt.Println(row["name"], row["score"])
|
|
}
|
|
```

## Notas
|
|
|
|
Agnóstica al driver — funciona con cualquier `*sql.DB` (sqlite, duckdb, postgres, clickhouse). Usa `sql.RawBytes` + `ColumnTypes()` para conversion dinamica. Convierte INTEGER→int64, FLOAT/REAL/DOUBLE→float64, BOOLEAN→bool, BLOB→[]byte, NULL→nil, resto→string. Para queries con muchos resultados considerar paginar con LIMIT/OFFSET.
