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

Question

我正在尝试运行查询：

let query =
    `
        DELETE FROM
            ${table_name}
        WHERE
            _id IN ($1::bigint[])
            AND
            account_id = $2
    `
let fields =
    [
        _ids,
        account_id,
    ]

但这给了我错误：

operator does not exist: bigint = bigint[]

_ids是一个数组。

注意

实施答案后出现的错误是：

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

这只是GraphQL错误，与postgres无关。

Answer 1

IN运算符期望set of rows with exactly one column或parenthesized list of scalar expressions。它不接受数组。

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

WHERE _id IN ($1:list)

Another answer建议使用= any，其中ANY是一个接受数组的Postgres operator：

WHERE _id = ANY ($1::int[])
