pg-promise

Question

我正在尝试运行查询：

let query =
    `
        DELETE FROM
            ${table_name}
        WHERE
            _id IN (::bigint[])
            AND
            account_id = 
    `
let fields =
    [
        _ids,
        account_id,
    ]

但它给我错误：

operator does not exist: bigint = bigint[]

_ids是一个数组。

注意

实施答案后我遇到的错误是：

GraphQLError: Int cannot represent non-integer value: []

这只是一个 GraphQL 错误，与 postgres 无关。

Answer 1

IN 运算符需要 set of rows with exactly one column, or a parenthesized list of scalar expressions。它不接受数组。

One answer 建议 :list，它告诉 pg-promise 做正确的事：

WHERE _id IN (:list)

Another answer suggests = any, where ANY is a Postgres operator 确实接受数组：

WHERE _id = ANY (::int[])

pg-promise - 错误运算符不存在：bigint = bigint[]

pg-promise - Error operator does not exist: bigint = bigint[]
