如果我们的语句为：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
|
IF
NOT
EXISTS(
SELECT
1
FROM
sys.views
WHERE
name
=
'Report_IndividualTicket'
)
BEGIN
create
view
Report_IndividualTicket
as
SELECT
Ticket.TicketNumber, Ticket.TicketID,
GisProcess.StageName,
Content.DtReceived, Content.ContentText
FROM
(GisProcess
INNER
JOIN
Ticket
ON
GisProcess.TicketID=Ticket.TicketID)
INNER
JOIN
Content
ON
Ticket.ContentID=Content.ContentID
END
|
会提示以下错误：
Msg 156, Level 15, State 1, Line 4
Incorrect syntax near the keyword 'view'.
出现这个错误的原因是：create view 这一句必须是批处理中的第一句。
所以可以将该语句修改为：
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14

IF EXISTS(
SELECT
1
FROM
sys.views
WHERE
name
=
'Report_IndividualTicket'
)
DROP
VIEW
Report_IndividualTicket
GO
create
view
Report_IndividualTicket
as
SELECT
Ticket.TicketNumber, Ticket.TicketID,
GisProcess.StageName,
Content.DtReceived, Content.ContentText
FROM
(GisProcess
INNER
JOIN
Ticket
ON
GisProcess.TicketID=Ticket.TicketID)
INNER
JOIN
Content
ON
Ticket.ContentID=Content.ContentID
