To query SQLite with Flux:
sql.from()and provide the following parameters:
- driverName: sqlite3
- dataSourceName: See data source name
- query: SQL query to execute
import "sql" sql.from( driverName: "sqlite3", dataSourceName: "file:/path/to/example.db?cache=shared&mode=ro", query: "SELECT * FROM example_table", )
Requires file system access
To query SQLite, Flux must have access to the filesystem. If Flux does not have access to the file system, the query will return an error similar to one of the following:
Error: unable to open database file
failed to read file: filesystem service is uninitialized
An internal error has occurred
If using InfluxDB Cloud or InfluxDB OSS, the Flux process does not have access to the filesystem.
SQLite data source name
sqlite3 driver uses the following DSN syntax (also known as a connection string):
SQLite to Flux data type conversion
sql.from() converts SQLite data types to Flux data types.
|SQLite data type||Flux data type|
|INT, INTEGER, BIGINT, SMALLINT, TINYINT||int|
|DATETIME, TIMESTAMP, DATE||time|
