从Sql Server Express 2005检索结构化Xml

Question

I would like to have xml output from Full Text Search indexed tables like below. but my code generates incorrect syntax near union my code

SELECT
Table1.Name 'Table1/Name',
Table1.Email 'Table1/Email',
(    SELECT
     Table2.Address 'Address',
     Table2.Phone 'Phone',
     FROM Details Table2
     INNER JOIN Regd Table3 ON Table3.Code = Table2.Code
     AND (Table3.SubCode = xml.SubCode) AND (Table1.Id = Table3.Id)
     FOR XML PATH ('Details'),Type) as 'Table1',
FROM Users Table1
INNER JOIN CONTAINSTABLE(Users,[Name], @SearchKeys) AS KEY_TBL ON Id = KEY_TBL.[KEY]
INNER JOIN Regd Table3 ON Table3.Id = Table1.Id,
OPENXML (@idoc,'/Request/List',2)
WITH (SubCode NVARCHAR(20)) as xml
WHERE  (xml.SubCode = '' or Table3.SubCode = xml.SubCode) AND (Table3.Id = Table1.Id)
FOR XML PATH ('List')
UNION
SELECT
SELECT
Table1.Name 'Table1/Name',
Table1.Email 'Table1/Email',
(    SELECT
     Table2.Address 'Address',
     Table2.Phone 'Phone',
     FROM Details Table2
     INNER JOIN Regd Table3 ON Table3.Code = Table2.Code
     AND (Table3.SubCode = xml.SubCode) AND (Table1.Id = Table3.Id)
     FOR XML PATH ('Details'),Type) as 'Table1',
FROM Users Table1
INNER JOIN CONTAINSTABLE(Users,[Email], @SearchKeys) AS KEY_TBL ON Id = KEY_TBL.[KEY]
INNER JOIN Regd Table3 ON Table3.Id = Table1.Id,
OPENXML (@idoc,'/Request/List',2)
WITH (SubCode NVARCHAR(20)) as xml
WHERE  (xml.SubCode = '' or Table3.SubCode = xml.SubCode) AND (Table3.Id = Table1.Id)
FOR XML PATH ('List')

here is out put i expected to have

<List>
<Table1>
<Name></Name>
<Email></Email>
<Details>
<Address></Address>
<Phone></Phone>
</Details>
</Table1>
</List>

i think request xml parameter would not be of any use here as it is just a syntax error

Answer 1

You have a lot of syntax errors in your code but I assume they are there because you have removed a lot of stuff that you thought was not necessary.

The error you say you get is Incorrect syntax near the keyword 'union' .

This will give you that error,

select *
from YourTable
for xml path('list')
union
select *
from YourTable
for xml path('list')

You have to embed the queries in a select statement like this.

select
(select *
 from YourTable
 for xml path('list'))
union
select
(select *
 from YourTable
 for xml path('list'))

If you want the columns to be of XML type you need to add type and use union all because The xml data type cannot be selected as DISTINCT because it is not comparable.

select
(select *
 from YourTable
 for xml path('list'), type)
union all
select
(select *
 from YourTable
 for xml path('list'), type)

I have no idea if this eventually will give you the output you want but this is the reason for Incorrect syntax near the keyword 'union' and what you can do about it.
