sql - ExactTarget -SFMC SQL 查询以添加天数

Question

运行查询以向电子邮件订阅者发送 +X 天电子邮件。FIRST_PROMO_SUBSCRIBE_DATE 来自 Oracle，他们说这不是 Salesforce SQL 的兼容格式，所以我有；

select * from PROMO_SUBSCRIBERS
where 
(ORDER_ENGAGEMENT_LAST_DT > dateadd(day,-335,CAST(FLOOR(CAST(GETDATE() AS FLOAT)) AS DATETIME)) 
or ORDER_ENGAGEMENT_LAST_DT is null)
and 
(ORDER_LAST_DT > dateadd(day,-1,CAST(FLOOR(CAST(GETDATE() AS FLOAT)) AS DATETIME)) 
or order_last_dt is null)

括号是否正确？

Answer 1

您应该能够将 Oracle 日期转换为date. 转换为date也会从datetimeT-SQL 中的字段中去除时间部分。

MS SQL Server 2008 架构设置：

CREATE TABLE promo_subscribers 
    (
     emailaddress varchar(255)
     , ORDER_ENGAGEMENT_LAST_DT  varchar(15)
     , ORDER_LAST_DT  varchar(15)

    );

INSERT INTO promo_subscribers
(emailaddress, ORDER_ENGAGEMENT_LAST_DT, ORDER_LAST_DT)
VALUES
('test@example.com', '01-APR-98', '01-APR-16'),
('test@example.com', '01-MAY-98', '06-APR-16')

查询 1：

select 
emailaddress
, order_engagement_last_dt
, cast(order_engagement_last_dt as date) datecast1
, order_last_dt
, cast(order_last_dt as date) datecast2
, dateadd(day,-335, cast(getDate() as date)) datecast3
, dateadd(day,-1, cast(getDate() as date)) datecast4
from PROMO_SUBSCRIBERS

结果：

|     emailaddress | order_engagement_last_dt |  datecast1 | order_last_dt |  datecast2 |  datecast3 |  datecast4 |
|------------------|--------------------------|------------|---------------|------------|------------|------------|
| test@example.com |                01-APR-98 | 1998-04-01 |     01-APR-16 | 2016-04-01 | 2015-05-08 | 2016-04-06 |
| test@example.com |                01-MAY-98 | 1998-05-01 |     06-APR-16 | 2016-04-06 | 2015-05-08 | 2016-04-06 |
