Write to SQLite
To write data to SQLite with Flux:
Import the
sql
package.Pipe-forward data into
sql.to()
and provide the following parameters:- driverName: sqlite3
- dataSourceName: See data source name
- table: Table to write to
- batchSize: Number of parameters or columns that can be queued within
each call to
Exec
(set to999
or less)
import "sql"
data
|> sql.to(
driverName: "sqlite3",
dataSourceName: "file:/path/to/example.db?cache=shared&mode=ro",
table: "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
The sqlite3
driver uses the following DSN syntax (also known as a connection string):
file:/path/to/example.db?param=value
Flux to SQLite data type conversion
sql.to()
converts Flux data types to SQLite data types.
Flux data type | SQLite data type |
---|---|
float | FLOAT |
int | INT |
uint | INT |
string | TEXT |
time | DATETIME |
