SQLSeal allows to transform your CSV files located in your vault into fully-fledged SQL database. You can use SQL statements to query this data however you like.
Once the library is published in Obsidian Official Community Repository: just head to Community Tab in your Obisidian Settings page and search for "SQLSeal".
Note: Please note that this plugin is in early phase. Basic functionality should work just fine but I do not take any responsibility for potential data loss and damage to your Vault.
On the first try plugin will download better_sqlite3.node binary to run database locally. This is due to the Obsidian restrictions to bundle everything in the main.js. The whole process of generating it is public and you can check it in the GitHub workflows.
The plugin creates database file in configuration folder .obsidian named sqlseal.db.
To manually install the package, open Releases and download .zip of the last one. Unzip it in your vault under .obsidian/Plugins/sqlseal.
Once you install the plugin, you can use it by creating sqlseal codeblocks in your notes. To create table base on the existing CSV file in your vault simply address it using the following command:
TABLE transactions = file(transactions.csv)
SELECT * FROM transactions LIMIT 10The code above will create table called transactions based on the transactions.csv file from your vault. Further you can refer to it using regular SELECT statements.
You can define multiple tables in a single snippet. You can also point to the tables defined in different snippets within the same note (for now tables stay local to the file).
