SELECT 使用 Union 查询并订购新的临时文件 table 无效

Question

我编写了一个 T-SQL 查询来从许多表中收集一些数据，并使用 select 联合查询将行分成三行。执行查询时出现错误。我附上了问题，请指导我纠正错误。

SELECT * 
INTO #tmpFerdeen 
FROM 
    (SELECT
         (CASE WHEN sc <> '0000' THEN sln END) AS t, 
         (CASE WHEN sc <> '0000' THEN crid END) AS crrid, 
         CASE Header 
            WHEN 'H' THEN 1  
            WHEN 'S' THEN 2 
            WHEN 'T' THEN 3 
            ELSE 0 
         END O,
         CASE 
            WHEN sc <> '0000' THEN Header 
         END, 
         CASE 
            WHEN sc <> '0000' THEN Header+'|'+st + '|'+convert(varchar,pid) + '|' + convert(varchar, cid) + '|' +convert(varchar,cenddate ) 
         END AS RestOfData
     FROM
         #tempsddd

     UNION ALL

     SELECT 
         sln t, crid crrid, 
         CASE Details 
            WHEN 'H' THEN 1  
            WHEN 'S' THEN 2 
            WHEN 'T' THEN 3 
            ELSE 0 
         END,
         Details, 
         Details + '|' + ISNULL(CONVERT(varchar, sln), '') + '|' + '|' + '|' + '|'
                 + ISNULL(CONVERT(varchar, ah), '') + '|'
                 + ISNULL(sfne, '') + '|' 
                 + ISNULL(smne, '') + '|' 
                 + ISNULL(slne, '')
   FROM
       #tempsddd

    UNION ALL

    SELECT
        (CASE WHEN sc <> '0000' THEN sln END) AS t, 
        (CASE WHEN sc <> '0000' THEN crid END) AS crrid, 
        CASE Footer 
           WHEN 'H' THEN 1  
           WHEN 'S' THEN 2 
           WHEN 'T' THEN 3 
           ELSE 0 
        END, 
        CASE WHEN sc <> '0000' THEN Footer END, 
        CASE WHEN sc <> '0000' THEN Footer + '|' + sc END
    FROM
        #tempsddd
    ORDER BY
        crrid, 
         CASE Header 
            WHEN 'H' THEN 1  
            WHEN 'S' THEN 2 
            WHEN 'T' THEN 3 
            ELSE 0 
         END)

请指导我这样做。

我认为这是不正确的语法，因为“Order by”语句，你应该把 order by 放在括号外，你也用 order by 之后的 case 所以请检查 case 语句是否正确

SELECT 使用 Union 查询并订购新的临时文件 table 无效

SELECT Queries with Union and order into a new temp table is not working

sql-server

union

temp
