# Function Results

> Block-versioned on-chain view function outputs — token metadata, oracle values. Time-travel queries over any contract state.

## Overview

* **Dataset ID:** `0122`
* **Table:** `blockdb_evm.b0122_function_results_v1`
* **Description:** On-chain function call return values versioned by block. Uses `contract_id` (26 bytes) to support metamorphic contracts; primary key is `(contract_id, block_number, call_data)`.
* **Primary key:** `(contract_id, block_number, call_data)`
* **API:** [POST /evm/raw/function-results](/api-reference/evm/primitives/function-results)
* **CSV Sample:** [Download](https://huggingface.co/datasets/BlockDB/Raw-Function-Results-Ethereum-And-EVM-Cryptocurrency-Data/resolve/main/data/blockdb_evm.b0122_function_results_v1.csv?download=true)

| `result`         | `BYTEA`       | Raw return data from the function call (null if reverted).                                                                                |
| `timestamp_utc`  | `TIMESTAMPTZ` | UTC timestamp when the function call result was recorded.                                                                                 |
