# YEAR, MONTH, DAY strul

## #1 — Erik Juhlin, 2002-09-17T08:19Z

Vad är problemet med den här SQL:en?

```
SELECT YEAR(a1.ActivityStartDate) AS ActivityStartYear
, MONTH(a1.ActivityStartDate) AS ActivityStartMonth, DAY(a1.ActivityStartDate) AS ActivityStartDay
[blue], (SELECT COUNT(*) FROM tblM_Activity a2 WHERE YEAR(a2.ActivityStartDate) = YEAR(a1.ActivityStartDate)
 AND MONTH(a2.ActivityStartDate) = MONTH(a1.ActivityStartDate) AND DAY(a2.ActivityStartDate) = DAY(a1.ActivityStartDate)) -- raden med felet[/blue]
 FROM tblM_Activity a1
 WHERE YEAR(a1.ActivityStartDate) = 2002 AND MONTH(a1.ActivityStartDate) = 09
 GROUP BY YEAR(a1.ActivityStartDate), MONTH(a1.ActivityStartDate), DAY(a1.ActivityStartDate)
 ORDER BY YEAR(a1.ActivityStartDate), MONTH(a1.ActivityStartDate), DAY(a1.ActivityStartDate)
```

Jag får felet:

> Server: Msg 8630, Level 17, State 38, Line 1
> Internal Query Processor Error: The query processor encountered an unexpected error during execution.

Vad händer om du inte använder en skalär subselect

```
SELECT YEAR(a1.ActivityStartDate) AS ActivityStartYear,
   MONTH(a1.ActivityStartDate) AS ActivityStartMonth, 
   DAY(a1.ActivityStartDate) AS ActivityStartDay,
   COUNT(*)  
from tblM_Activity a1
 WHERE YEAR(a1.ActivityStartDate) = 2002 
AND MONTH(a1.ActivityStartDate) = 09
 GROUP BY 
  YEAR(a1.ActivityStartDate), 
   MONTH(a1.ActivityStartDate), 
  DAY(a1.ActivityStartDate)
 ORDER BY 
   YEAR(a1.ActivityStartDate), 
   MONTH(a1.ActivityStartDate), 
   DAY(a1.ActivityStartDate)
```

Av felmeddelandet att döma så har du stött på något fel i databashanteraren.
