生產從多個表中的SQL Server

Question

XML是否有可能產生使用下面的XML「FOR XML」在SQL Server

<Person> 
    <HomeID>1</HomeID> 
     <DayID>1</DayID> 
      <String>I get up at 07:00</String> 
      <String>I have breakfast at 07:30</String> 
      <String>I go to office at 08:00</String> 
      <String>I have lunch at 13:00</String> 
      <String>I come back from office at 17:00</String> 
      <String>I have dinner at 19:00</String> 
      <String>I sleep at 21:30</String> 
     <DayID>2</DayID> 
      <String>I get up at 08:00</String> 
      <String>I have breakfast at 08:30</String> 
      <String>I have lunch at 13:00</String> 
      <String>I have dinner at 20:00</String> 
      <String>I sleep at 23:00</String> 
    </Person> 
    <Person> 
    <HomeID>2</HomeID> 
     <DayID>1</DayID> 
      <String>I get up at 07:00</String> 
      <String>I have breakfast at 07:30</String> 
      <String>I go to office at 08:00</String> 
      <String>I have lunch at 13:00</String> 
      <String>I come back from office at 17:00</String> 
      <String>I have dinner at 19:00</String> 
      <String>I sleep at 21:30</String> 
     <DayID>2</DayID>   
      <String>I get up at 08:00</String> 
      <String>I have breakfast at 08:30</String> 
      <String>I have lunch at 13:00</String> 
      <String>I have dinner at 20:00</String> 
      <String>I sleep at 23:00</String> 
    <Person> 

我最初的嘗試是非常糟糕的。

Select HomeID, 
    (
    Select DayID, 
    (
    SELECT TB2.RndString+' '+CAST(TB1.timevalue AS varchar(5)) 
    FROM TB1,TB2 
    where TB1.DayID=TB2.DayType and TB1.TimeCode=TB2.StringCode 
    FOR XML PATH ('String'), TYPE 
    ) 
    from TB1 
    for XML AUTO, TYPE 
    ) 
    from TB1 
    for XML AUTO, ELEMENTS

我有兩個表，TB1和TB2。在TB1

字段是HomeID，大衛·，時間碼，TIMEVALUE。

HomeID DayID TimeCode timevalue 
    1  1  1   07:00:00 
    1  1  2   07:30:00 
    1  1  3   08:00:00 
    1  1  4   13:00:00 
    1  1  5   17:00:00 
    1  1  6   19:00:00 
    1  1  7   21:30:00 
    1  2  1   08:00:00 
    1  2  2   08:30:00 
    1  2  3   13:00:00 
    1  2  4   20:00:00 
    1  2  5   23:00:00 
    2  1  1   08:00:00 
    2  1  2   08:30:00 
    2  1  3   09:00:00 
    2  1  4   13:00:00 
    2  1  5   18:00:00 
    2  1  6   20:00:00 
    2  1  7   22:00:00 
    2  2  1   09:00:00 
    2  2  2   10:00:00 
    2  2  3   13:00:00 
    2  2  4   19:00:00 
    2  2  5   22:30:00 

TB2中的字段是DayType，StringCode，RndString。

DayType  StringCode RndString 
    1  1   I get up at 
    1  2   I have breakfast at 
    1  3   I go to office at 
    1  4   I have lunch at 
    1  5   I come back from office at 
    1  6   I have dinner at 
    1  7   I sleep at 
    2  1   I get up at 
    2  2   I have breakfast at 
    2  3   I have lunch at 
    2  4   I have dinner at 
    2  5   I sleep at 

注： TB1.DayID = TB2.DayType和TB1.TimeCode = TB2.StringCode

我不認爲你需要的XML是最適合你，所以我會建議其他結構爲你。

select T1_1.HomeID as [@HomeID], 
     (
     select T1_2.DayID as [@ID], 
       (
       select T2.RndString+' '+left(T1_3.TimeValue, 5) as '*' 
       from TB1 as T1_3 
       inner join TB2 as T2 
        on T1_3.DayID = T2.DayType and 
        T1_3.TimeCode = T2.StringCode 
       where T1_2.HomeID = T1_3.HomeID and 
        T1_2.DayID = T1_3.DayID 
       order by T2.StringCode 
       for xml path('String'), type 
      ) 
     from TB1 as T1_2 
     where T1_2.HomeID = T1_1.HomeID 
     group by T1_2.DayID, 
       T1_2.HomeID 
     order by T1_2.DayID 
     for xml path('Day'), type 
     ) 
from TB1 as T1_1 
group by T1_1.HomeID 
order by T1_1.HomeID 
for xml path('Person') 

結果：

<Person HomeID="1"> 
    <Day ID="1"> 
    <String>I get up at 07:00</String> 
    <String>I have breakfast at 07:30</String> 
    <String>I go to office at 08:00</String> 
    <String>I have lunch at 13:00</String> 
    <String>I come back from office at 17:00</String> 
    <String>I have dinner at 19:00</String> 
    <String>I sleep at 21:30</String> 
    </Day> 
    <Day ID="2"> 
    <String>I get up at 08:00</String> 
    <String>I have breakfast at 08:30</String> 
    <String>I have lunch at 13:00</String> 
    <String>I have dinner at 20:00</String> 
    <String>I sleep at 23:00</String> 
    </Day> 
</Person> 
<Person HomeID="2"> 
    <Day ID="1"> 
    <String>I get up at 08:00</String> 
    <String>I have breakfast at 08:30</String> 
    <String>I go to office at 09:00</String> 
    <String>I have lunch at 13:00</String> 
    <String>I come back from office at 18:00</String> 
    <String>I have dinner at 20:00</String> 
    <String>I sleep at 22:00</String> 
    </Day> 
    <Day ID="2"> 
    <String>I get up at 09:00</String> 
    <String>I have breakfast at 10:00</String> 
    <String>I have lunch at 13:00</String> 
    <String>I have dinner at 19:00</String> 
    <String>I sleep at 22:30</String> 
    </Day> 
</Person>
