Use: `sq QUERY`,

|
Short: "sq",
|
|
Long: `sq is a swiss-army knife for wrangling data.
|
|
|
|
Use sq to query Postgres, SQLite, SQLServer, MySQL, CSV, TSV
|
|
and Excel, and output in text, JSON, CSV, Excel, HTML, etc., or
|
|
output to a database table.
|
|
|
|
You can query using sq's own jq-like syntax, or in native SQL.
|
|
|
|
Execute "sq completion --help" for instructions to install shell completion.
