今天在SQLite中創建視圖時，遇著點小麻煩，先把已經做好的SQL2005的創建視圖語句直接用于SQLite的視圖創建，

--SQL2005中的視圖創建語句

CREATE?VIEW [dbo].[VIEW_SYS_REGION]
AS
SELECT
Province.Code AS province_CODE, province.name AS Province,
City.Code AS City_Code, city.name AS City,
Area.Code AS Area_Code, area.name AS Area, area.ZipCode AS ZipCode
FROM
?(select * from .dbo.sys_region where level=1) as province
left join
?(select * from .dbo.sys_region where level=2) as city
??on city.parent_code=province.code
left join
?(select * from .dbo.sys_region where level=3) as area
??on area.parent_code=city.code

?

在SQLite中執行結果報錯： SQL Error: near ".": syntax error

然后改為

--SQLite中創建視圖

CREATE VIEW [VIEW_SYS_REGION]
AS
SELECT
Province.[Code] AS province_CODE, province.[name] AS Province,
City.[Code] AS City_Code, city.[name] AS City,
Area.[Code] AS Area_Code, area.[name] AS Area, area.[ZipCode] AS ZipCode
FROM
?(select * from sys_region where level=1) as province
left join
?(select * from sys_region where level=2) as city
??on city.[parent_code]=province.[code]
left join
?(select * from sys_region where level=3) as area
??on area.[parent_code]=city.[code]

?

執行成功，錯誤點：表別名.字段名? 改為 表別名.[字段名]，即將字段名放入方括號中。就這一點點問題，郁悶。
