influxdb3 create table
The influxdb3 create table command creates a new table in a specified database. Tables must include at least one tag column and can optionally include field columns with defined data types.
InfluxDB automatically creates tables when you write line protocol data. Use this command only if you need to define a custom schema or apply a custom partition template before writing data.
Usage
# Syntax
influxdb3 create table [OPTIONS] \
--tags [<TAGS>...] \
--database <DATABASE_NAME> \
--token <AUTH_TOKEN> \
<TABLE_NAME>Arguments
- TABLE_NAME: The name of the table to create.
Options
| Option | Description | |
|---|---|---|
-H | --host | Host URL of the running InfluxDB 3 Core server (default is http://127.0.0.1:8181) |
-d | --database | (Required) Name of the database to operate on |
--token | (Required) Authentication token | |
--tags | (Required) Comma-separated list of tag columns to include in the table | |

Tag and field naming requirements
Tag and field keys are alphanumeric and must start with a letter or number.
They can contain dashes (-) and underscores (_).
Option environment variables
You can use the following environment variables to set options instead of passing them via CLI flags:
| Environment Variable | Option |
|---|---|
INFLUXDB3_HOST_URL | --host |
INFLUXDB3_DATABASE_NAME | --database |
INFLUXDB3_AUTH_TOKEN | --token |
INFLUXDB3_TLS_NO_VERIFY | --tls-no-verify |
Examples
In the examples below, replace the following:
DATABASE_NAME: The database nameAUTH_TOKEN: The authentication tokenTABLE_NAME: A name for the new table
Create an empty table
influxdb3 create table \
--tags tag1,tag2,tag3 \
--database DATABASE_NAME \
--token AUTH_TOKEN \
TABLE_NAMECreate a table with tag and field columns
influxdb3 create table \
--tags room,sensor_id \
--fields temp:float64,hum:float64,co:int64 \
--database DATABASE_NAME \
--token AUTH_TOKEN \
TABLE_NAMEVerification
Use the SHOW TABLES query to verify that the table was created successfully:
influxdb3 query \
--database my_test_db \
--token AUTH_TOKEN \
"SHOW TABLES"
Example output:
+---------------+--------------------+----------------------------+------------+
| table_catalog | table_schema | table_name | table_type |
+---------------+--------------------+----------------------------+------------+
| public | iox | my_sensor_table | BASE TABLE |
| public | system | distinct_caches | BASE TABLE |
| public | system | last_caches | BASE TABLE |
| public | system | parquet_files | BASE TABLE |
+---------------+--------------------+----------------------------+------------+SHOW TABLES is an SQL query. It isn’t supported in InfluxQL.
