SQL Server 2014中的ROWS BETWEEN函数

Question

Not sure why I'm getting this error.

Query:

SELECT
    TURBINE, YR, MO, D,
    AVG(Z_SCORE) OVER (PARTITION BY TURBINE ORDER BY ROWNO ROWS BETWEEN 13 PRECEDING AND CURRENT ROW) AS ROLLINGAVG
FROM 
    #ORDERED

Sample Data

Rowno    Turbine     Yr     Mo  D    Z_Score
--------------------------------------------------------
5153    KV#G04_25   2016    5   27  0.530932540472319 
5154    KV#I11_47   2016    5   27  -0.0887050712447865 
5155    KV#B04_08   2016    5   27  0.983732236771842 
5156    KV#B05_09   2016    5   27  0.0127747723017027

ERROR:

Msg 102, Level 15, State 1, Line 75
Incorrect syntax near 'ROWS'

Most errors regarding this error are about using an older version of SQL Server but I'm using 2014. ROWS should work fine.

I've also tried this without the partition by and used a group by instead. That also didn't work. Any time there's "OVER" and "ROWS" I get an error.

Answer 1

The code looks good to me, are you working on a database in a Pre 2012 compatibility level? not all functionality is avilable in older versions of SQL Server

Answer 2

The query worked for me in SQL Server 2016 with the sample data provided.

SELECT  TURBINE
,       YR
,       MO
,       D
,       AVG(Z_SCORE) OVER ( PARTITION BY TURBINE ORDER BY ROWNO ROWS BETWEEN 13 PRECEDING AND CURRENT ROW ) AS ROLLINGAVG
FROM    #ORDERED;
