Question

我正在开发以下SQL来创建固定资产重新合并报告。理想情况下，我尝试使用以下字段为每个分支最终添加1行：

(1) Branch
(2) Department
(3) Fixed Asset Account
(4) Fixed Asset Amount 
(5) PS Fixed Asset Amount
(6) Difference between Cols 4 and 5
(7) Accum Depreciation Account
(8) Accum Depreciation Amount
(9) PS Accum Depreciation Amount
(10) Difference between cols 8 and 9

SQL返回我需要的数据，但许多分支有2行，如下所示：

0101  10001010   1501  (blank)   (blank)  (blank)   1601  100.00   101.00   1.00
0101  10001010   1501   250.00   255.00    5.00     1601  blank  blank     blank

我希望看到的是：

0101   1001010   1501   250.00   255.00   5.00   1601   100.00    101.00   1.00

这是我目前的sql：

SELECT 
ir.ERAC_BRANCH_LGCY_CD AS Branch,
pdr.Department,

pdr.ACCOUNT_FA AS FA_ACCT,
SUM(pdr.COST) AS FA_AMT,
CASE WHEN pdr.account_fa = pgal.acct_nbr THEN pgal.pstd_ttl_amt END AS PS_FA_AMT,
fa_amt - ps_fa_amt AS FA_DIFF,

pdr.account_ad AS AD_ACCT,
SUM(pdr.depr_ltd) AS AD_AMT,
CASE WHEN pdr.account_ad = pgal.acct_nbr THEN pgal.pstd_ttl_amt  END AS PS_AD_AMT,
ad_amt - ps_ad_amt AS AD_DIFF

FROM PSFS.PS_DEPR_RPT pdr 

INNER JOIN PSFS.PS_GL_ACCT_LDGR PGAL 
    ON pdr.deptid =grp_br_ps_org_id
    AND (pdr.account_fa = pgal.acct_nbr or pdr.account_ad = pgal.acct_nbr)
    AND fiscal_yr_mth_nbr = 201508

INNER JOIN INTGRT_RPT.DIM_LOCATION IR 
      ON pdr.deptid = ir.erac_branch_ps_org_cd AND ir.curr_lrd_row_flg = 1

WHERE pdr.BUSINESS_UNIT = 'A0465'
AND pdr.BOOK = 'PERFORM'
AND pdr.FISCAL_YEAR = 2015
AND pdr.ACCOUNTING_PERIOD = 8
AND pdr.GROUP_ASSET_FLAG <> 'M'

GROUP BY 1,2,3,5, 7,9

ORDER BY 3,1, 2

简单解决此问题，对于您怀疑可能为null或空白的每个列/字段使用聚合函数Max()。聚合函数忽略大多数SQL引擎中的NULL。

示例示例

select * from tablename

id         col1               col2      col3
---------- ---------- ----------
1         Joey               250.00     255.00
1        (blank)            (blank)    (blank)

使用Max（）

Select id, max(col1),max(col2), max(col3)
FROM tablename
Group by.....

     id         col1               col2      col3
    ---------- ---------- ----------
    1         Joey             250.00        250.00
