Question

我们有一个MS SQL Server 2012，我需要帮助找出使用SQL查询的某些模式输出。下面结果的第一个字段需要是硬编码字母。 D代表人口统计，R代表收入，P代表设计。这是架构的sqlfiddle示例： here

预期结果：

D   ID101   James   
R   ID101   $10     
P   ID101   1001    
D   ID102   Rock    
R   ID102   $50     
P   ID102   1002    
D   ID103   Paul    
R   ID103   $30     
P   ID103   1003

  union
  select 'P', * from Design
)

from t
