Use InfluxDB client libraries to query data
Use the InfluxDB v3 client libraries with SQL or InfluxQL to query data stored in InfluxDB. InfluxDB v3 client libraries are language-specific packages that integrate with your application. Execute queries and retrieve data and metadata over the Flight+gRPC protocol, and then process data using tools in the language of your choice.
Use Go
Use the influxdb3-go Go package and SQL or InfluxQL to query data stored in InfluxDB. Execute queries and retrieve data over the Flight+gRPC protocol, and then process data using common Go tools.
import (
"context"
"github.com/InfluxCommunity/influxdb3-go/v2/influxdb3"
)
func Query() error {
client, err := influxdb3.New(influxdb3.ClientConfig{
Host: "https://cloud2.influxdata.com",
Token: "DATABASE_TOKEN",
Database: "DATABASE_NAME",
})
defer func(client *influxdb3.Client) {
err := client.Close()
if err != nil {
panic(err)
}
}(client)
query := `SELECT *
FROM home
WHERE time >= '2022-01-02T08:00:00Z'
AND time <= '2022-01-02T20:00:00Z'`
iterator, err := client.Query(context.Background(), query)
...
}
Use Python
Use the influxdb_client_3 Python module and SQL or InfluxQL to query data stored in InfluxDB. Execute queries and retrieve data over the Flight+gRPC protocol, and then process data using common Python tools.
from influxdb_client_3 import InfluxDBClient3
# Instantiate an InfluxDB client
client = InfluxDBClient3(
host='cloud2.influxdata.com',
token='DATABASE_TOKEN',
database='DATABASE_NAME'
)
# Execute the query and return an Arrow table
table = client.query(
query="SELECT * FROM home",
language="sql"
)
# Return query results as a markdown table
print(table.to_pandas().to_markdown())
