Typrom 返回带有 IsNull 和 IsNotNull 条件的 SQL 查询

Question

I am trying to get list of items where deletedAt Column isNotNull but typeorm is returning where condition for deletedAt Column

Typeorm

    const query = Results.createQueryBuilder('results');
    query.where('results.deletedAt IS NOT NULL');
    query.skip(page * limit);
    query.take(limit);
    console.log(query.getQuery());
    return query.getManyAndCount();

it returns SQL Query as below

SELECT "results"."id" AS "results_id", "results"."date" AS "results_date", "results"."shift" AS "results_shift", "results"."result" AS "results_result", "results"."createdAt" AS "results_createdAt", "results"."updatedAt" AS "results_updatedAt", "results"."deletedAt" AS "results_deletedAt" FROM "results" "results" WHERE ( "results"."deletedAt" IS NOT NULL ) AND ( "results"."deletedAt" IS NULL ) LIMIT 10

Packages

    "typeorm": "^0.3.7"
    "@nestjs/typeorm": "^8.1.4",
    "@nestjs/common": "^8.0.0",

I guess results entity has a @DeleteDateColumn in it? If yes, the IS NULL part will be automatically applied, plus the one you've entered manually.
