Question

我在格式良好的XML中返回以下查询时遇到问题。我能想到的最好的是使用AUTO，Elements但不返回任何根。任何帮助表示赞赏。我在SQL 2005或更高版本中没有任何问题，只是麻烦SQL 2000（将很快升级:)）

SELECT 
 dbid AS DatabaseID
,NAME AS DatabaseName
,CASE 
    WHEN NAME IN ('master','mb','model','tempdb','distribution') THEN 'S'
    ELSE 'U'
 END AS SysUserType 
,cmptlevel AS CompatibilityLevel
,databasepropertyex(NAME, 'Collation') AS CollationName
,CASE databasepropertyex(NAME, 'Status') 
    WHEN 'ONLINE'              THEN 0
    WHEN 'RESTORING'           THEN 1
    WHEN 'RECOVERING'          THEN 2
    WHEN 'RECOVERY_PENDING'    THEN 3
    WHEN 'SUSPECT'             THEN 4
    WHEN 'EMERGENCY'           THEN 5
    WHEN 'OFFLINE'             THEN 6
    WHEN 'COPYING'             THEN 7
 END AS State
,databasepropertyex(NAME, 'Status') AS StateDesc
,CASE databasepropertyex(NAME, 'Recovery')
    WHEN 'FULL'                THEN 1
    WHEN 'BULK_LOGGED'         THEN 2
    WHEN 'SIMPLE'              THEN 3
 END AS RecoveryModel
,databasepropertyex(NAME, 'Recovery') AS RecoveryModelDesc
,crdate AS DatabaseCreationDate
,(SELECT MAX(bs.backup_finish_date) FROM msdb.dbo.backupset AS bs WHERE bs.database_name=name) AS LastBackupDate  
,(SELECT (SUM(saf.size) * 8 / 1024) FROM sysaltfiles AS saf WHERE saf.dbid=dbid) AS  SizeMB
,(SELECT COUNT(sp.dbid) FROM sysprocesses AS sp WHERE dbid > 0 AND spid >= 51 AND sp.dbid=dbid) AS ActiveDBConnections 
,SERVERPROPERTY('Machinename') AS SQLServerName
,CASE 
    WHEN SERVERPROPERTY('Instancename') IS NULL
        THEN 'Default'
    ELSE SERVERPROPERTY('Instancename')
    END AS SQLServerInstanceName
,SERVERPROPERTY('ProductVersion') AS SQLServerVersion
,SERVERPROPERTY('Edition') AS SQLServerEdition
FROM sysdatabases  
ORDER BY DatabaseID
FOR XML AUTO, ELEMENTS

Answer 1

由于SQL-Server 2000不知道真正的XML数据类型并且只返回一个字符串，因此您可以轻松实现：

SELECT N'<root>' + (Your FOR XML AUTO,ELEMENTS query here) + N'</root>';

但我没有2000服务器进行测试......

祝你好运！

SQL 2000很难回收良好的XML
