IPSQL is a decentralized database that can run in IPFS. It implements the SQL schema, data model, and query language.

This project is pre-alpha and under heavy active development. Do not use in production, breaking changes will land without notice.

The primary way to interact with IPSQL right now is via the command line. You can install it with npm or use npx to run it without installing locally.

$ ipsql help
ipsql [command]

Commands:
  bin.js query <uri> <sql>  Run IPSQL query
  bin.js repl <uri>         Run local REPL
  bin.js import             Import CSV files

Options:
  --help     Show help                                                 [boolean]
  --version  Show version number                                       [boolean]

The JS API is currently considered internal until the churn in the code base dies down.

• Importing CSV files

• CREATE
  • DATABASE (it isn't clear how we would want to implement and support this yet)
  • TABLE
    • INTEGER
    • VARCHAR(size)
    • FLOAT
    • DATE
    • TIME
    • DATETIME
    • BLOB (should use the FBL, values smaller than 32b will be inline binary, below 1MB should be a single raw block link, anything else is a full tree FBL as a stream)
    • TEXT (may never support, according to spec this is upt 2GB of string data so it's hard to figure out what the inline vs linking rules would be. Instead, using VARCHAR as the inlined string and BLOB the probably linked type)
    • BOOLEAN (this isn't actually supported in the SQL parser we use, must be quite rare)
• ALTER TABLE
• INSERT
  • ROWS INSERT INTO table_name VALUES ( 'test' )
  • COLUMNS INSERT INTO table_name ( column_name ) VALUES ( 'test' )
• UPDATE
  • UPDATE SET w/o WHERE
  • UPDATE SET WHERE
• DELETE
  • DELETE w/o WHERE (deletes table)
  • DELETE WHERE
• SELECT
  • * SELECT * FROM table_name
  • COLUMNS SELECT column1, column2 FROM table_name
  • ROWID meta column
  • TOP
  • MIN
  • MAX
  • COUNT
  • AVG
  • SUM
  • LIKE pattern
  • WHERE
    • AND
    • OR
    • ASC, DESC
    • basic comparison (=, >, <, >=, <=)
    • <>
    • GROUP BY

    • LIKE
    • IN
    • NOT
