Current logical schema for lake.international_stock

Coverage and timing

Non-US listing metadata: country, shares outstanding, company name. No prices.

Inspect source dates and nullable fields before interpreting a result. A completed query is not proof that the source is current, complete for every security, or public at an event’s occurrence time.

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.
