Yes, I can show you my code:
```
func (svc *DpeService) ExecuteParameterizedQuery(query string, args []any) {
config := flightsql.DriverConfig{
Address: fmt.Sprintf("%s:%s", svc.Host, svc.Port),
Token: "",
Timeout: 10 * time.Second,
Params: make(map[string]string),
}
db, err := sql.Open("flightsql", config.DSN())
if err != nil {
log.Fatalf("open failed: %v", err)
}
defer db.Close()
stmt, err := db.Prepare(query)
if err != nil {
log.Fatalf("query failed: %s", err)
}
rows, err := stmt.Query(args...)
if err != nil {
log.Fatalf("query failed: %s", err)
}
defer rows.Close()
columns, err := rows.Columns()
if err != nil {
log.Fatalf("getting columns failed: %s", err)
}
log.Println("columns:", columns)
// Prepare the list of data-points according to the received row
columnData := make([]interface{}, len(columns))
columnDataPtr := make([]interface{}, len(columns))
for i := range columnData {
columnDataPtr[i] = &columnData[i]
}
idx := 0
for rows.Next() {
idx++
if err := rows.Scan(columnDataPtr...); err != nil {
log.Fatalf("scanning row %d failed: %s", idx, err)
}
for j := range columns {
fmt.Printf("%.22v ", columnData[j])
}
fmt.Println()
}
if err := rows.Err(); err != nil {
log.Fatalf("iterating rows failed: %s", err)
}
}
```
Trying to run the query:
```
func (svc *assetService) GetSensorsByAssetId(assetId string) {
query := `SELECT * FROM $1 WHERE ASSET_ID = $2 LIMIT 1`
args := []any{
svc.assetType,
id.String(),
}
svc.dpeSvc.ExecuteParameterizedQuery(query, args)
}
```
With this code I get the error:
`SQL error: ParserError(\"Expected identifier, found: $1\")`
