Perform SQL

const sql_create_table = `
    CREATE TABLE \`user\` (
      \`id\` int(11) NOT NULL AUTO_INCREMENT,
      \`name\` varchar(64) NOT NULL,
      \`created_time\` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
      \`modified_time\` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
      \`deleted\` boolean DEFAULT false,
      PRIMARY KEY (\`id\`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
`;

const step0 = await mysql_dbc_table.dbSqlAsync(dbc, sql_create_table);

Use data model with DbTable

const DbTable = mysql_dbc_table.DbTable;
class User extends DbTable {
    static fields() {
        return {
            id: {fmt: parseInt},
            name: {fmt: String, default: ''},
            created_time: {fmt: (...args) => new Date(...args)},
            modified_time: {fmt: (...args) => new Date(...args)},
            deleted: {fmt: Boolean, default: false},
        }
    }
}

const db_user = new User('user', dbc);
const existed = await db_user.existAsync();

const users = await db_user.findAsync();
const user = await db_user.findOneAsync();
