What is the best way to locate the entity with the earliest date using typeORM?

I am currently working on querying an entity with a date column in order to find the entity with the earliest created date. Can someone guide me on how I can achieve this using TypeORM?

Here is what I have tried so far:

const earliest_result = await getRepository(Verification).findOne({ where: {
    created_date: // Need to find the earliest date
}});

This is how my model is structured:

export class Verification { 

    @Column({ nullable: false })
    success!: boolean

    @CreateDateColumn()
    created_date!: Date
};

Answer №1

In order to achieve the desired outcome, one could follow a simple yet not fully optimized approach by sorting in descending order and selecting the first result. It is essential to ensure that there is an index on the date column if the table contains a large number of records.

export class Verification { 

    @Column({ nullable: false })
    success!: boolean

    @Index()
    @CreateDateColumn()
    created_date!: Date
};

const latest_entry = await getRepository(Verification).find({
   skip:0,
   take:1,
   order: { created_date: "DESC" }
});
