        await this.depositMoney("Chansu", 100);
    }

    @Transactional(Propagation.MANDATORY)
    private async depositMoney(userId: string, amount: number) {
        console.log("Execute Query", userId, amount);
        await ctx().execute("UPDATE user SET balance = balance + ? WHERE id = ?", [amount, userId]);
    }

    @Transactional(Propagation.MANDATORY)
    private async withdrawMoney(userId: string, amount: number) {
        console.log("Execute Query", userId, amount);
        await ctx().execute("UPDATE user SET balance = balance - ? WHERE id = ?", [amount, userId]);
    }
}

Start Transaction (id: ae8wml5i78rt) # Transaction started at transfer()
