        "content": "Here\u2019s a review of your query plus suggestions and corrections, based on the current Beancount / bean-query syntax as of early 2026. I'll walk through what works, what doesn\u2019t, and how to get exactly the data you need (all income for a given year). I\u2019ll assume you want the year 2025.\n\n---\n\n## What your query is doing\n\nYou wrote:\n\n```\nyear=2025 \nnext_year=2026 \nfrom=from open on $year-01-01 close on $next_year-01-01 \nbean-query -f csv main.bean \\\n  select account, sum(position) as total $from \\\n  where account ~ 'Income' \\\n  group by account \\\n  order by account \\\n```\n\nLet\u2019s unpack that:\n\n- You define `$year = 2025` and `$next_year = 2026`.\n- In the `FROM`\u2010clause you use `open on 2025-01-01 close on 2026-01-01`.\n- The `SELECT` gives `account, sum(position) as total`.\n- The `WHERE` filters accounts matching `'Income'`.\n- Then you `GROUP BY account` and order by account.\n\nThis is close to the documented correct pattern. Beancount\u2019s query language supports `FROM OPEN ON <date> CLOSE ON <date>` to limit your dataset to transactions that occur between those directives, which is what you want for a year-based income summary. ([beancount.github.io](https://beancount.github.io/docs/beancount_query_language.html?utm_source=openai))\n\nThe sample given in the documentation for an income statement for year 2013 is:\n\n```\nSELECT account, sum(position)\nFROM OPEN ON 2013-01-01 CLOSE ON 2014-01-01\nWHERE account ~ \"Income|Expenses\"\nGROUP BY 1\nORDER BY 1;\n```\n\nSo your structure matches what's documented. ([beancount.github.io](https://beancount.github.io/docs/beancount_query_language.html?utm_source=openai))\n\n---\n\n## Some issues / refinements\n\nHere are some possible problems and improvements:\n\n1. **Regex in `WHERE account ~ 'Income'`**  \n   Writing `account ~ 'Income'` will match any account name containing the substring `Income`. That\u2019s okay if all income accounts are under an `Income:` prefix. But better is to use a more precise regex such as `^Income:` so you don\u2019t accidentally include accounts like `Equity:PreviousIncome` or similar. Or if your plan is to include multiple account types, you could use `~ '^Income:'`.\n\n2. **Filtering only `Income`accounts**  \n   If you use `WHERE account ~ \"Income\"` then all `Income:\u2026` accounts usually have *negative* postings (depending on your ledger bookkeeping). If you want *all income earned* as a positive number, you may need to *invert* the sign (e.g. use `-sum(position)`), depending how your postings have been entered. The documentation says income balances are \u201cnegative\u201d in many reports. ([beancount.github.io](https://beancount.github.io/docs/the_double_entry_counting_method.html?utm_source=openai))\n\n3. **From clause syntax spelling / casing / quoting**  \n   Be sure to use the correct capitalization, spacing and quoting. The documentation example uses **`FROM OPEN ON 2013-01-01 CLOSE ON 2014-01-01`** (all caps keywords). Also make sure there\u2019s a space between `OPEN` and `ON`, etc. Incorrect spelling or quoting might result in a parse error.  \n\n4. **Grouping / ordering by index or literal**  \n   In the example documentation they do `GROUP BY 1` (meaning first non-aggregate column, i.e. account). Using `GROUP BY account` is equivalent. But consistency might help. Similarly, ordering by column index (`ORDER BY 1`) is fine. Also be careful to avoid mixing literal and positional groupings in complex queries. ([beancount.github.io](https://beancount.github.io/docs/beancount_query_language.html?utm_source=openai))\n\n5. **Date bounds inclusive/exclusive**  \n   The `CLOSE ON 2026-01-01` means up to but not including 2026-01-01? Typically that means \u201ctransactions with date < 2026-01-01 and \u2265 2025-01-01\u201d. That exactly corresponds to year 2025. It looks right in your case.\n\n6. **Use of variable expansion**  \n   If you are using shell variables like `$year` and `$next_year`, ensure your shell interpolation is doing what you expect (e.g. quoting doesn\u2019t mess up). Sometimes better to write the dates literally or generate them once and verify.\n\n7. **Output format**  \n   The `-f csv` option is fine; it causes bean-query to output CSV. Just make sure the header and decimal/currency columns are handled as you expect.\n\n---\n\n## Suggested corrected version\n\nPutting together all the above, here\u2019s a cleaned-up version that should reliably give *all income earned in 2025*:\n\n```\nbean-query -f csv main.bean \\\n  \"SELECT account, -SUM(position) AS total_income\n   FROM OPEN ON 2025-01-01 CLOSE ON 2026-01-01\n   WHERE account ~ '^Income:'\n   GROUP BY account\n   ORDER BY account;\"\n```\n\nThings to note:\n\n- I prefixed the regex with `^Income:` to match only top-level income accounts.\n- I put a minus sign on `SUM(position)` to convert negative income postings to positive (if your income postings are recorded as negative amounts\u2014which is standard in Beancount). If your postings for income are *positive* in your file, omit the minus.\n- Wrapped the query in quotes so shell variables aren\u2019t mis-interpreted if you want to replace `2025` with a variable.\n- Ensured the `FROM OPEN ON \u2026 CLOSE ON \u2026` appears before `WHERE`.\n\n---\n\n## Verify it works\n\nHere are some steps you can take to be sure:\n\n- Run a variant without summing, just list all postings to `Income:` in 2025:\n\n  ```\n  bean-query main.bean \\\n    \"SELECT date, account, position\n     FROM OPEN ON 2025-01-01 CLOSE ON 2026-01-01\n     WHERE account ~ '^Income:';\"\n  ```\n\n  This lets you inspect whether some postings are missing or the positions are negative/positive.\n\n- Run the aggregate query and compare sum of those positions to what you expect from your records (e.g. total revenue or income for 2025 from your accounting).\n\n- If you have sub-accounts under `Income:`, you will get rows per subaccount; if you want a single line total, omit `GROUP BY account` and instead do:\n\n  ```\n  SELECT -SUM(position) AS total_income\n  FROM OPEN ON 2025-01-01 CLOSE ON 2026-01-01\n  WHERE account ~ '^Income:';\n  ```\n\n---\n\n## Summary\n\n- Your overall pattern *is correct* and closely matches the official examples.  \n- Improve precision by using `^Income:` regex.  \n- Possibly add a `-` to `sum(position)` if needed, to report income as positive.  \n- Ensure proper ordering of `FROM ... CLOSE ON` before `WHERE`.  \n\nIf you like, I can also help you craft a reusable template so you can query any year by passing a parameter (in shell, or via bean-inquiry plugin). Do you want help with that?"

        "content": "Yes \u2014 you\u2019re understanding it correctly. It\u2019s better style and more efficient to use the `FROM OPEN ON \u2026 CLOSE ON \u2026` clause to specify the date\u2010range (i.e. the year), *instead* of filtering by year in the `WHERE` clause using something like `year(date) = $year`. The Beancount query engine offers both, but each has different semantics and performance implications.\n\nHere\u2019s a breakdown based on the Beancount docs:\n\n---\n\n## What Beancount supports\n\nFrom the official Beancount Query Language docs:\n\n- There *is* a built-in `year` property for each transaction/posting. You can write `WHERE year = 2025` (or `year >= 2025 AND year < 2026`). ([beancount.github.io](https://beancount.github.io/docs/beancount_query_language.html?utm_source=openai))  \n- There are also built-in simple functions like `YEAR(date)`, `MONTH(date)` etc. ([beancount.github.io](https://beancount.github.io/docs/beancount_query_language.html?utm_source=openai))  \n- But there are important performance and logical reasons to prefer the `FROM ... OPEN ON ... CLOSE ON ...` clause when you want to bound your report to a period. In fact, documentation suggests filtering by date *earlier* (in the `FROM` part) is more efficient, because it reduces how many entries/postings must be loaded into the query context. ([beancount.io](https://beancount.io/es/docs/Basics/beancount-query-language?utm_source=openai))  \n\n---\n\n## Why prefer `FROM OPEN ON \u2026 CLOSE ON \u2026` for date/range bounding\n\nHere are the benefits:\n\n1. **Efficiency**: The `FROM \u2026 CLOSE ON \u2026` specification limits the dataset *before* applying `WHERE` and aggregation, reducing memory/work early. If you only `WHERE year = \u2026`, then all postings are loaded, filtered later, which is less efficient for large ledgers. ([beancount.io](https://beancount.io/es/docs/Basics/beancount-query-language?utm_source=openai))\n\n2. **Correctness relative to accounting semantics**: The `CLOSE ON` option ensures that you include transactions up to but not including the closing date (with the usual convention that the closing date is one day beyond your last intended date). That helps avoid off-by-one issues around boundary dates. ([beancount.github.io](https://beancount.github.io/docs/beancount_query_language.html?utm_source=openai))\n\n3. **Simplicity and clarity**: Using `FROM OPEN ON 2025-01-01 CLOSE ON 2026-01-01` clearly shows the period you\u2019re interested in. It separates \u201cwhat time period\u201d from other filters like accounts. That tends to make queries easier to maintain.\n\n---\n\n## When `WHERE year = $year` or `YEAR(date) = $year` might be OK / useful\n\nThere are some cases where using those filters is appropriate:\n\n- If you want to group by year (or have a multi-year query), for example:\n\n  ```\n  SELECT account, YEAR(date) AS yr, sum(position)\n  WHERE account ~ '^Income:'\n  GROUP BY account, yr\n  ORDER BY yr\n  ```\n\n  Here the `YEAR()` function in `SELECT` and grouping by it makes sense. ([beancount.github.io](https://beancount.github.io/docs/beancount_query_language.html?utm_source=openai))\n\n- If bounding dates via `FROM ... CLOSE ON ...` isn't expressive enough (e.g. dealing with 'month' boundaries that don\u2019t align with calendar dates or needing multiple separate date criteria) then you might combine them.\n\n- For quick one-off filtering where performance isn\u2019t a concern and you're more interested in flexibility than speed.\n\n---\n\n## What you *should* do for your use case\n\nSince you want *all income for a single calendar year* (e.g. 2025), the cleanest, most correct way is:\n\n- Use `FROM OPEN ON 2025-01-01 CLOSE ON 2026-01-01` to bound exactly the year 2025.  \n- Use `WHERE account ~ '^Income:'` (to filter for income accounts).  \n- If your income postings are negative (as is the default semantic for income vs expense in Beancount), use a negated `SUM(position)` to report income as a positive number.\n\nE.g.:\n\n```\nbean-query -f csv main.bean \\\n\"SELECT account, -SUM(position) AS total_income\n FROM OPEN ON 2025-01-01 CLOSE ON 2026-01-01\n WHERE account ~ '^Income:'\n GROUP BY account\n ORDER BY account;\"\n```\n\nYou generally *won\u2019t* need `WHERE YEAR(date) = 2025` when you\u2019ve got the `FROM OPEN ON \u2026 CLOSE ON \u2026`, though adding it *won\u2019t necessarily break*\u2014but it could be redundant, slower, or introduce confusion with boundary cases.\n\n---\n\nIf you like, I can show you example queries with both methods side by side (one using `FROM \u2026 CLOSE ON`, one using `WHERE YEAR(...)`, and compare their outputs so you can see the difference. Want me to do that?"
