Step 1: Create the database
Run the following SQL statements to create a new database called trades
which has two tables: trade
and company
. The trades
table is a columnstore table meant to contain analytical data about specific trades on a given company and the company
table is a small rowstore table that provides metadata about that company.
CREATE DATABASE IF NOT EXISTS trades; USE trades; DROP TABLE IF EXISTS trade; CREATE TABLE trade( id BIGINT NOT NULL, stock_symbol CHAR(5) NOT NULL, shares DECIMAL(18,4) NOT NULL, share_price DECIMAL(18,4) NOT NULL, trade_time DATETIME(6) NOT NULL, SORT KEY(stock_symbol), SHARD KEY(stock_symbol) ); DROP TABLE IF EXISTS company; CREATE ROWSTORE TABLE company( symbol CHAR(5) NOT NULL, name VARCHAR(50), last_sale VARCHAR(10), market_cap VARCHAR(15), IPO_year INT, sector VARCHAR(80), industry VARCHAR(80), summary_quote VARCHAR(50), extra VARCHAR(50) );
