我想在sql 2000中将行2行转换为2列而不使用pivot

Question

我想在sql 2000中将行2行转换为2列 不使用枢轴

例如：

A    B    C
---- ---- -------
78   68   3

我希望输出为

Projects  Count
--------- ------- 
A         78
B         68  
C         3

Answer 1

SELECT
  pivot.field,
  CASE pivot.field
    WHEN 'A' THEN A
    WHEN 'B' THEN B
    WHEN 'C' THEN C
  END as value
FROM
  my_table
CROSS JOIN
  (SELECT 'A' AS field UNION ALL SELECT 'B' UNION ALL SELECT 'C') AS pivot

Answer 2

如果我理解正确，您确实需要透视查询：

select 'A' as Projects, A as my_count from mytab
union all
select 'B' as Projects, B as my_count from mytab
union all
select 'C' as Projects, C as my_count from mytab

（我用my_count替换了count，因为COUNT是SQL中的保留字。）
