=======确定全文索引是否可用：

SELECT
dtb.is_fulltext_enabled AS [IsFullTextEnabled]
FROM
master.sys.databases AS dtb
WHERE
(dtb.name=N'DLib')

=======表中全文索引的几本信息：

SELECT
CAST(fti.is_enabled AS bit) AS [IsEnabled],
OBJECTPROPERTY(fti.object_id,'TableFullTextPopulateStatus') AS [PopulationStatus],
(case change_tracking_state when 'M' then 1 when 'A' then 2 else 0 end) AS [ChangeTracking]
FROM
sys.tables AS tbl
INNER JOIN sys.fulltext_indexes AS fti ON fti.object_id=tbl.object_id
WHERE
(tbl.name=N'AreaInfo' and SCHEMA_NAME(tbl.schema_id)=N'dbo')

=======获得全文索引列：

SELECT
col.name AS [Name]
FROM
sys.tables AS tbl
INNER JOIN sys.fulltext_indexes AS fti ON fti.object_id=tbl.object_id
INNER JOIN sys.fulltext_index_columns AS icol ON icol.object_id=fti.object_id
INNER JOIN sys.columns AS col ON col.object_id = icol.object_id and col.column_id = icol.column_id
WHERE
(tbl.name=N'AreaInfo' and SCHEMA_NAME(tbl.schema_id)=N'dbo')

=======获得获得服务器名：

select SERVERPROPERTY(N'servername')

=======排序规则信息：

SELECT
dtb.collation_name AS [Collation],
dtb.name AS [DatabaseName2]
FROM master.sys.databases AS dtb
WHERE (dtb.name=N'master')

SELECT
CAST(COLLATIONPROPERTY(name, 'LCID') AS int) AS [LocaleID]
FROM sys.fn_helpcollations() cl
WHERE (cl.name=N'Chinese_PRC_CI_AS')

=======获取兼容级别：

SELECT
dtb.compatibility_level AS [CompatibilityLevel],
dtb.name AS [DatabaseName2]
FROM master.sys.databases AS dtb
WHERE (dtb.name=N'DLib')

=======表名和架构名：
SELECT
SCHEMA_NAME(tbl.schema_id) AS [Schema],
tbl.name AS [Name]
FROM sys.tables AS tbl
WHERE (tbl.name=N'AreaInfo' and SCHEMA_NAME(tbl.schema_id)=N'dbo')

=======Version：

SELECT
(@@microsoftversion / 0x1000000) & 0xff AS [VersionMajor]

=======创建时间、所属文件组等信息：

SELECT
tbl.name AS [Name],
tbl.object_id AS [ID],
tbl.create_date AS [CreateDate],
tbl.modify_date AS [DateLastModified],
SCHEMA_NAME(tbl.schema_id) AS [Schema],
