FireQL can be used as a Go library or interactive command-line tool.

Go Library

An example of querying collections using SQL syntax:

import (
    "github.com/pgollangi/fireql"
)

func main() {
    fql, err := fireql.New("<GCP_PROJECT_ID>")
    //OR
    fql, err = fireql.New("<GCP_PROJECT_ID>", fireql.OptionServiceAccount("<SERVICE_ACCOUNT_JSON>"))
    if err != nil {
        panic(err)
    }

    // Now, execute SELECT query
    result, err := fql.Execute("SELECT * `users` order by id desc limit 10")
    if err != nil {
        panic(err)
    }
    _ = result
}

Command-Line

fireql [flags]

Example:

$ fireql --project $PROJECT_ID

Examples

Some cool SELECT queries that are possible with FireQL:

select * from users
select *, id as user_id from users
select id, email as email_address, `address.city` AS city from `users`
select * from users order by 'address.city' desc limit 10
select * from `users` where id > 50
select id, LENGTH(contacts) as total_contacts from `users`

See Wiki for more examples.

Limitations

All of firestore query limitations are applicable when running queries using FireQL.

In addition to that:

• Only SELECT queries for now. Support for INSERT, UPDATE, and DELETE might come in the future.

• Only AND conditions supported in WHERE clause.

• No support for JOINs.

• LIMIT doesn't accept an OFFSET, only a single number.

• No support of GROUP BY and aggregate function COUNT.

Future scope

• Expand support for all logical conditions in WHERE clause by internally issuing multiple query requests to Firestore and merging results locally before returning.

• GROUP BY support

• Support other DML queries: INSERT, UPDATE, and DELETE
