Question

我正在尝试将UNION COUNT查询的结果添加到一起，以便轻松获得“总计”。我的SQL查询是一个简单的UNION，任何人都可以建议我如何添加生成的结果给我一个总数？

SELECT 'BOXES' AS DATASET,  
       COUNT(RECORD_TABLE) AS RECORDS_IN_ARCHIVE
FROM dbo.VIEW_GLOBAL_SEARCH 
WHERE RECORD_TABLE = 'TB_BOXES'
GROUP BY RECORD_TABLE 
UNION 
SELECT 'MAPS' AS DATASET,  
       COUNT(RECORD_TABLE) AS RECORDS_IN_ARCHIVE
FROM dbo.VIEW_GLOBAL_SEARCH 
WHERE RECORD_TABLE = 'MAPS'
GROUP BY RECORD_TABLE

我的结果如下所示，我想添加一个包含记录总数的“TOTAL”列。

DATASET      RECORDS_IN_ARCHIVE
TB_BOXES     3149
TB_MAPS      856

Answer 1

为UNION使用公用表表达式应该诀窍：

WITH rawdata AS (
  SELECT 'BOXES' AS DATASET,  
       COUNT(RECORD_TABLE) AS RECORDS_IN_ARCHIVE
  FROM dbo.VIEW_GLOBAL_SEARCH 
    WHERE RECORD_TABLE = 'TB_BOXES'
  GROUP BY RECORD_TABLE 
UNION 
  SELECT 'MAPS' AS DATASET,  
       COUNT(RECORD_TABLE) AS RECORDS_IN_ARCHIVE
  FROM dbo.VIEW_GLOBAL_SEARCH 
    WHERE RECORD_TABLE = 'MAPS'
  GROUP BY RECORD_TABLE
) SELECT SUM(RECORDS_IN_ARCHIVE) FROM rawdata;

Answer 2

WITH CTE AS (
SELECT Record_Table, COUNT(Record_Table) Records_In_Archive
FROM dbo.VIEW_GLOBAL_Search
WHERE Record_Table IN ('Maps','TB_Boxes')
GROUP BY Record_Table
ORDER BY Record_Table
)
SELECT ISNULL(Case Record_Table WHEN 'TB_Boxes' THEN 'Boxes' ELSE Record_Table 
END,'Total') Record_Table,
SUM(Records_In_Archive) Records_In_Archive
FROM CTE
GROUP BY Case Record_Table WHEN 'TB_Boxes' THEN 'Boxes' ELSE Record_Table END 
WITH ROLLUP
ORDER BY Record_Table

虽然，如果您正在寻找单独的结果：

SELECT 'Total', COUNT(Record_Table)
FROM dbo.VIEW_Global_Search
WHERE Record_Table IN ('TB_Boxes','Maps')

为什么要考虑这个？

Answer 3

你的意思是添加新行总数？

SELECT RECORD_TABLE AS DATASET,  
       COUNT(RECORD_TABLE) AS RECORDS_IN_ARCHIVE 
FROM dbo.VIEW_GLOBAL_SEARCH 
WHERE RECORD_TABLE IN ('TB_BOXES', 'MAPS')
GROUP BY RECORD_TABLE 
UNION ALL
SELECT 'TOTAL' AS DATASET,  
       COUNT(RECORD_TABLE) AS RECORDS_IN_ARCHIVE 
FROM dbo.VIEW_GLOBAL_SEARCH 
WHERE RECORD_TABLE IN ('TB_BOXES', 'MAPS');
