Use: `sq QUERY`,
|
|
Short: "sq",
|
|
Long: `sq is a swiss-army knife for wrangling data.
|
|
|
|
$ sq '@sakila_pg | .actor | .first_name, .last_name | .[0:10]' --json
|
|
|
|
Use sq to query Postgres, SQLite, SQLServer, MySQL, CSV, Excel, etc,
|
|
and output in text, JSON, CSV, Excel and so on, or write output to a
|
|
database table.
|
|
|
|
You can query using sq's own jq-like syntax, or in native SQL.
|
|
|
|
Use "sq inspect" to view schema metadata. Use the "sq tbl" commands
|
|
to copy, truncate and drop tables. Use "sq diff" to compare source metadata
|
|
and row data.
|
|
|
|
See docs and more: https://sq.io`,

|
Example: `# Add Postgres source identified by handle @sakila_pg
|
|
$ sq add --handle=@sakila_pg 'postgres://user:pass@localhost:5432/sakila'
|
|
|
|
# List available data sources.
|
|
$ sq ls
|
|
|
|
# Set active data source.
|
|
$ sq src @sakila_pg
|
|
|
|
# Get specified cols from table address in active data source.
|
|
$ sq '.actor | .actor_id, .first_name, .last_name'
|
|
|
|
# Ping a data source.
|
|
$ sq ping @sakila_pg
|
|
|
|
# View metadata (schema, stats etc) for data source.
|
|
$ sq inspect @sakila_pg
|
|
|
|
# View metadata for a table.
|
|
$ sq inspect @sakila_pg.actor
|
|
|
|
# Output all rows from 'actor' table in JSON.
|
|
$ sq -j .actor
|
|
|
|
# Alternative way to specify format.
|
|
$ sq --format json .actor
|
|
|
|
# Output in text format (with header).
|
|
$ sq -th .actor
|
|
|
|
# Output in text format (no header).
|
|
$ sq -tH .actor
|
|
|
|
# Output to a HTML file.
|
|
$ sq --html '@sakila_pg.actor' -o actor.html
|
|
|
|
# Join across data sources.
|
|
$ sq '@my1.person, @pg1.address | join(.uid) | .username, .email, .city'
|
|
|
|
# Insert query results into a table in another data source.
|
|
$ sq --insert=@pg1.person '@my1.person | .username, .email'
|
|
|
|
# Execute a database-native SQL query, specifying the source.
|
|
$ sq sql --src=@pg1 'SELECT uid, username, email FROM person LIMIT 2'
|
|
|

# Copy a table (in the same source).
