Columns and types

These columns come from the same versioned logical catalog used by the query validator and engine. They describe the fields you can query. Some historical rows have missing values; fields absent from older shards can return typed NULL.

Current logical schema for lake.reports

Coverage and timing

Model-generated analyst ratings. Present in both engines and referenced by the screener, but absent from the catalog — so any lake query touching it was rejected as an unknown table.

The one table here that HAS `fiscalYear` and `fiscalPeriod` (`Q1`–`Q4`, `FY`); the SEC statement tables do not. `rating` is a DOUBLE on a 0–5 scale — read "fundamentally strong" as `rating >= 3.5`.

Run a limited query

Use a registered API key with lake scope. Select needed columns, bind user-supplied values and restrict dates when the table has a time dimension. Query results are durable parts with a schema and manifest rather than an unbounded in-memory array.

This reference documents the schema and its meaning. Run queries in your signed-in workspace; this page does not execute SQL or show private results and datasets.
