在 Azure Data Studio 和 SSMS 或 SSRS 中执行 SQL 查询时的不同行为

问题描述

我有一个查询，它的行为取决于执行它的客户端。 我使用 Azure Data Studio 获得了即时结果（163 行）。 sql Management Studio、报表生成器、SSRS 网络门户超过 7 分钟。

更好的是，如果我从 select 中删除两列或添加 2 个空列，我在 SSMS 中实现了相同的性能。

SELECT
  mycols,(...),null,null
FROM
(...)

解释方案是一样的，我什么都看不懂。调整顾问没有建议。

我认为这与为什么客户端选项有关，唯一不同的是 ARITHMETIC_ABORT_ENABLED 为 FALSE。在SSMS中设置为true后仍然没有效果。

我使用 sql Server 2019。

这是查询：

DECLARE @UserID as VARCHAR(30) = CURRENT_USER 
DECLARE @ProductionCenterSwipCode as VARCHAR(30) = 'AIX'
DECLARE @ResourceName as VARCHAR(30) = NULL
DECLARE @ActivityCode as VARCHAR(30) = '{ALL}'
DECLARE @subactivityCode as VARCHAR(30) = '{ALL}'
DECLARE @WorkNatureCode as VARCHAR(30) = '{ALL}'
DECLARE @ClientId as INT = -9999
DECLARE @ContractId as INT = -9999
DECLARE @StartDate as DATE= CAST( '2021-04-01' AS DATE)
DECLARE @EndDate as DATE = CAST( '2021-05-30' AS DATE)

解决方法

这是一个 SQL Server 错误。 Microsoft 支持人员的回答：

问题：您遇到了特定查询的性能问题。在 SSMS 和 SSRS，需要更长的时间才能完成。在 Azure Data Studio 上 和 SQL CMD，它运行得更快

修复了在 SQL Server 2019 中使用 UTF8 的数据库在半连接后查询输出 NULL 值时的性能问题。

要解决此问题，您必须在 SQL 上应用最新的 CU，即 CU11

一开始微软很难搞清楚，因为当时他们不知道行为会根据 SQL 客户端而改变。 现在他们知道了^^
