nestjs pgsql where 条件与 OR 和 AND Nodejs typeorm

Question

在下面的查询中，我想搜索名称和协议编号，但在 OR 模式下，如果名称或协议编号匹配，则查找，但它不能像这样工作

async findAll(filter: DataFilterDto): Promise<ApiResponseDto> {
    const take = filter.count || 10;
    const pageNo = filter.pageNo > 0 ? filter.pageNo - 1 : 0;
    const skip = pageNo * take;

    let where: FindOptionsWhere<AgreementEntity> = {};
    if (HelperService.isValueValid(filter.id)) {
      where["id"] = filter.id;
    }

    if (HelperService.isValueValid(filter.enquiryId)) {
      where["enquiryId"] = filter.enquiryId;
    }

    if (HelperService.isValueValid(filter.applicantId)) {
      where["applicantId"] = filter.applicantId;
    }

    if (HelperService.isValueValid(filter.searchText)) {
      const iLike = ILike(`%${filter.searchText}%`);
      // where["name"] = iLike;
      // where["agreementNumber"] = iLike;

      // Create an OR condition for name and agreementNumber fields
      where['_OR'] = [
        { 'name': iLike },
        { 'agreementNumber': iLike }
      ];
    }

    const query = {
      where: where,
      relations: ["enquiryInfo", "enquiryInfo.applicantInfo"],
      order: { id: SortOrder.Desc },
      take,
      skip,
    };

    let [result, total] = await this.agreementsRepo.findAndCount(query);
    return { data: result, count: total };
  }

尝试修改创建 OR 条件的部分，如下所示：

// ...

if (HelperService.isValueValid(filter.searchText)) {
  const iLike = ILike(`%${filter.searchText}%`);

  // Create an OR condition for name and agreementNumber fields
  where['OR'] = [
    { 'name': iLike },
    { 'agreementNumber': iLike }
  ];
}

// ...

确保将“_OR”替换为“OR”。在 TypeORM 中定义 OR 条件的正确键是“OR”。
