Using "in" operator with uuid types causes "invalid input syntax" error

Issue type:

• bug report

Database system/driver:

• postgres v11

TypeORM version:

• latest 0.2.26

With postgres, “in” operator is valid on UUID types:

SELECT x.* FROM my_table x WHERE x."_id" IN ('77dec6ee-8d39-4b73-825a-6190628d2953','7900b8c6-c239-45e1-9ca8-2d1a244eb881')

However, the following code throws an error:

repository.find({
    where: {
      _id: In(['77dec6ee-8d39-4b73-825a-6190628d2953', '7900b8c6-c239-45e1-9ca8-2d1a244eb881']),
    }
});

QueryFailedError invalid input syntax for type uuid: "{"_type":"in","_value":["77dec6ee-8d39-4b73-825a-6190628d2953", "7900b8c6-c239-45e1-9ca8-2d1a244eb881"],"_useParameter":true,"_multipleParameters":true}"

I believe the answer to this question is in this other issue: https://github.com/typeorm/typeorm/issues/1985

All you have to do is use the new ‘…’ operator to spread the array inside the In clause of your query, like so:

export const queryBatchFunction = <T extends { id: string }>(repository: Repository<T>) => async (
  keys: string[],
): Promise<(T | null)[]> => {
  const docs = await repository
    .createQueryBuilder("TableName")
    .where(`TableName.id IN (:...keys)`, { keys })
    .getMany();

  return keys.map(k => docs.find(d => d.id === k) || null);
};

Note the :...key thing, but I don’t see this’s being mentioned anywhere in the changelog… Am I missing anything?

Similar effect for inside query builder…

qb.andWhere("v.customer IN (:customers)", { customers: ["548b47a3-61b9-48f4-b1f2-eb83011a20d5"]});

throwing this error:

Interestingly, the search will work if I add the parameter value inside the query, but only if I use single quotes like here:

qb.andWhere("v.customer IN ('548b47a3-61b9-48f4-b1f2-eb83011a20d5')");
