[User] I want to find the total number of ERC1155 "approval-for-all" events per contract. Show contract_address and the approval_count.

[Assistant]
SELECT contract_address, COUNT(*) AS approval_count
FROM erc1155_approval_for_all
GROUP BY contract_address;

[User] Also show the number of unique wallet holders currently holding any token from those contracts by joining to nft_holders.

[Assistant]
SELECT a.contract_address,
       a.approval_count,
       COALESCE(b.holder_count, 0) AS holder_count
FROM (
  SELECT contract_address, COUNT(*) AS approval_count
  FROM erc1155_approval_for_all
  GROUP BY contract_address
) a
LEFT JOIN (
  SELECT contract_address, COUNT(DISTINCT wallet_address) AS holder_count
  FROM nft_holders
  GROUP BY contract_address
) b
  ON a.contract_address = b.contract_address;

[User] Filter to only include contracts where holder_count is greater than 50.

[Assistant]
SELECT a.contract_address,
       a.approval_count,
       b.holder_count

  FROM nft_holders
  GROUP BY contract_address
  HAVING COUNT(DISTINCT wallet_address) > 50
) b
  ON a.contract_address = b.contract_address;

[User] Sort results by approval_count descending and limit to the top 10.

[Assistant]
SELECT a.contract_address,
       a.approval_count,
       b.holder_count

[Assistant] SELECT name, symbol, floor_price, token_count FROM nft_collections WHERE blockchain = 'Ethereum' ORDER BY CAST(floor_price AS FLOAT) DESC;

[User] Can you also show the owner of each collection in the result?

[Assistant] SELECT name, symbol, floor_price, token_count, owner FROM nft_collections WHERE blockchain = 'Ethereum' ORDER BY CAST(floor_price AS FLOAT) DESC;

[User] Now only include collections whose floor price is greater than 1 ETH.

[Assistant] SELECT name, symbol, floor_price, token_count, owner FROM nft_collections WHERE blockchain = 'Ethereum' AND CAST(floor_price AS FLOAT) > 1 AND floor_price_symbol = 'ETH' ORDER BY CAST(floor_price AS FLOAT) DESC;
