For previous examples typescript error occurs in createQueryBuilder that says “Argument of type 'string' is not assignable to parameter of type 'QueryRunner'.ts(2345)”. If you check the type of createQueryBuilder, the string cannot come as the first argument. The types of createQueryBuilder are as follows. myDataSource.createQueryBuilder<ObjectLiteral>(entityClass: EntityTarget<ObjectLiteral>, alias: string, queryRunner?: QueryRunner | undefined):
1.1 KiB
1.1 KiB
Delete using Query Builder
Delete
You can create DELETE queries using QueryBuilder.
Examples:
await myDataSource
.createQueryBuilder()
.delete()
.from(User)
.where("id = :id", { id: 1 })
.execute()
This is the most efficient way in terms of performance to delete entities from your database.
Soft-Delete
Applying Soft Delete to QueryBuilder
await dataSource.getRepository(Entity).createQueryBuilder().softDelete()
Examples:
await myDataSource
.createQueryBuilder('users')
.softDelete()
.where("id = :id", { id: 1 })
.execute();
Restore-Soft-Delete
Alternatively, You can recover the soft deleted rows by using the restore() method:
await dataSource.getRepository(Entity).createQueryBuilder().restore()
Examples:
await myDataSource
.createQueryBuilder('users')
.restore()
.where("id = :id", { id: 1 })
.execute();
