我在 nestjs 最新版本中使用 MySQL 和 Typeorm,并且我有以下实体:
shop.entity.ts:
@Entity() export class Shop { @PrimaryGeneratedColumn("uuid") id: string; @Column({ unique: true, nullable: false }) name: string; @Column({ nullable: true }) description: string; @Column({ default: "" }) image_url: string; @Column({ default: true }) is_active: boolean; @Column({ default: false }) is_special: boolean; @Column({ nullable: false, default: () => "CURRENT_TIMESTAMP" }) created_at: Date; }
offer.entity.ts
@Entity() export class Offer { @PrimaryGeneratedColumn("uuid") id: string; @Column({ nullable: false }) name: string; @Column({ nullable: false }) fabric: string; @Column({ nullable: false }) code: string; @Column({ nullable: false }) start_date: Date; @Column({ nullable: false }) end_date: Date; @Column({ default: "" }) description: string; @Column({ nullable: false, default: () => "CURRENT_TIMESTAMP" }) created_at: Date; }
shop.service.ts 过滤查询
async filter(filter: FilterShopDto) { const queryBuilder = this.shopRepository .createQueryBuilder("shop") .where( `shop.description LIKE :description`, { description: filter.description ? `%${filter.description}%` : "%", }, ) .orderBy("shop.created_at", "DESC") .skip(filter.skip) .take(filter.take) }
offer.service.ts 报价过滤器
async filter(filter: FilterOfferDto) { const queryBuilder = this.offerRepository .createQueryBuilder("offer") .where( " offer.description LIKE :description", { description: filter.description ? `%${filter.description}%` : "%", }, ) .orderBy( "offer.created_at", "DESC", ) .skip(filter.skip) .take(filter.take) }
每个查询都工作得很好,但我想做的是将这两个查询合并为一个查询,这样我可以从商店和报价中获得搜索结果,并对记录进行排序,然后应用跳过并接受它们。 有什么办法可以做到吗?
TypeORM 使您能够随心所欲地使用任何查询。使用 entityManager.query() 这是文档。 p>
