# Query SQLite

To query [SQLite](https://www.sqlite.org/index.html) with Flux:

1. Import the [`sql` package](/flux/v0/stdlib/sql/).
    
2. Use [`sql.from()`](/flux/v0/stdlib/sql/from/) and provide the following parameters:
    
    -   **driverName**: sqlite3
    -   **dataSourceName**: *See [data source name](#sqlite-data-source-name)*
    -   **query**: SQL query to execute

```js
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

The `sqlite3` driver uses the following DSN syntax (also known as a **connection string**):

```
file:/path/to/example.db?param=value
```

## 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 |
| FLOAT, DOUBLE | float |
| DATETIME, TIMESTAMP, DATE | time |
| BOOL | int |
| TEXT | string |

All other SQLite data types are converted to strings.
