Question

我的数据如下所示（通常超过2条记录）

OBLIGOR  OBN_NUM     XPTYPE NET_UNUSED BANK_ASSET 
-------------------------------------------------
 1       000100000   0101    100         0
 1       000100001   5151    100         0
 1       000100002   5151     50         0

当我使用以下SQL时，我只能求和为100。但我想得到250。

SELECT  
    SUM(NET_UNUSED) + SUM(BANK_ASSET) AS BANK_ASSET,  
    OBLIGOR AS OBLIGOR, 
    SUBSTRING (OBN_NUM,1,4) AS OBN_NUM
FROM 
    RB_CRM_DEV.[IN].STG_SF_I_DC
WHERE 
    SUBSTRING (OBN_NUM,1,4) = SUBSTRING (OBN_NUM,1,4)
    AND SUBSTRING( XPTYPE,1,1) IN (0,1)
GROUP BY  
    OBLIGOR, SUBSTRING (OBN_NUM, 1, 4)
ORDER BY
    OBLIGOR, SUBSTRING(OBN_NUM, 1, 4)

如何确保我的记录集至少应包含xptype as 0,1条记录才能在此查询中检查（因为SUBSTRING(XPTYPE,1,1) IN (0,1)条件会删除其他两条记录）。

Answer 1

好吧，如果我正确理解了您的要求，那么您所追求的就是xptype以0或1开头的Obligor的任何记录的存在，例如，您可以使用EXISTS检查一下：

SELECT  SUM(NET_UNUSED)+SUM(BANK_ASSET) AS BANK_ASSET,  OBLIGOR AS OBLIGOR, 
  SUBSTRING (OBN_NUM,1,4) AS OBN_NUM
FROM RB_CRM_DEV.[IN].STG_SF_I_DC A
WHERE EXISTS (
  SELECT 1 FROM RB_CRM_DEV.[IN].STG_SF_I_DC B
  WHERE SUBSTRING (A.OBN_NUM,1,4) = SUBSTRING (B.OBN_NUM,1,4)
    AND A.OBLIGOR = B.OBLIGOR
    AND SUBSTRING( B.XPTYPE,1,1) IN (0,1)
  )
GROUP BY  OBLIGOR, SUBSTRING (OBN_NUM,1,4)
ORDER by OBLIGOR,SUBSTRING(OBN_NUM,1,4)

应该工作。如果这不是您想要的，请用更多示例数据编辑您的问题，以准确显示您想要的内容。

使用连接的另一种方法-

SELECT Sum(t1.net_unused) + Sum(t1.bank_asset) AS BANK_ASSET, 
       t1.obligor                              AS OBLIGOR, 
       Substring (t1.obn_num, 1, 4)            AS OBN_NUM 
FROM   rb_crm_dev.[IN].stg_sf_i_dc t1 
       INNER JOIN (SELECT obligor, 
                          obn_num 
                   FROM   rb_crm_dev.[IN].stg_sf_i_dc 
                   WHERE  Substring(xptype, 1, 1) IN ( 0, 1 )) t2 
               ON t1.obligor = t2.obligor 
                  AND Substring (t1.obn_num, 1, 4) = 
                      Substring (t2.obn_num, 1, 4) 
GROUP  BY t1.obligor, 
          t1.Substring (obn_num, 1, 4) 
ORDER  BY t1.obligor, 
          t1.Substring(obn_num, 1, 4)

我需要编写SQL Server查询的帮助
