小编pra*_*gil的帖子

我的查询如下

SELECT w.payload,
       Count('payload') OVER () AS ROWCOUNT
FROM wholesale_confirmation.wholesale_order_confirmation w
WHERE w.delivery_date = COALESCE(NULL, w.delivery_date)
  AND w.ship_to_location_id = COALESCE(NULL, w.ship_to_location_id)
  AND w.order_raised_date = COALESCE(NULL, w.order_raised_date)
  AND w.ship_from_location_id = COALESCE(NULL, w.ship_from_location_id)
LIMIT 10
OFFSET 0;

这给了我这样的结果：

我想要{"payload:"[payload1,payload2,payload3],"rowcount":n}。

Postgres 10.3版，payload数据类型为jsonb

@Bean
public DynamoDbClient amazonDynamoDB() {
    final AssumeRoleRequest assumeRoleRequest = AssumeRoleRequest.builder().roleSessionName(UUID.randomUUID().toString()).roleArn("roleArn").build();
    final StsAssumeRoleCredentialsProvider  stsAssumeRoleCredentialsProvider = StsAssumeRoleCredentialsProvider.builder().refreshRequest(assumeRoleRequest).build();
    return DynamoDbClient.builder().credentialsProvider(stsAssumeRoleCredentialsProvider).region(Region.EU_WEST_1)
            .build();
}

出现错误
