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.stock_splits

Coverage and timing

Split events per ticker: execution date and the from/to ratio.

Do NOT re-apply these onto `sec_daily_ohlc.closingPrice` — that series is already split-adjusted, so applying the ratio again double-counts. Use this table to reason about split events themselves, or alongside `unadjustedClose`.

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.
