Question

我遇到了这个错误：

“由于这种类型的相关子查询模式不受支持内部错误“

在Matillion（Redshift的ETL工具）上执行以下查询时。

SELECT DISTINCT
  "sap"."tracking_no" AS "tracking_no",
  (select case when len("sap"."order_create_time")=6 and
                 regexp_instr("sap"."order_create_date",'[a-zA-Z]')=0 and 
                 regexp_instr("sap"."order_create_time",'[a-zA-Z]')=0
            then CAST(CONCAT(CONCAT(cast(isnull("sap"."order_create_date",'1900-01-01') as VARCHAR(10)), ' '),
                   CONCAT(CONCAT(CONCAT(CONCAT(SUBSTRING(isnull("sap"."order_create_time",'000000'), 1,2), ':'),
                   SUBSTRING(isnull("sap"."order_create_time",'000000'), 3,2)),':'),

     ON "fedex"."TRACKING_NUMBER" = "sap"."tracking_no"
WHERE sap.order_create_date is not null and
      fedex.DELIVERY_DATE is not null

我尝试搜索分辨率，但在互联网上找不到任何解决方案。

是否与红移群集有关，因为它表示内部错误？

任何帮助都将不胜感激。

我特此发布现在有效的更新查询。删除select前面的case语句，它可以正常工作。

由于内部错误，不支持相关子查询模式的类型
