Question

我正在使用sql server 2005。我正在编写一个T sql脚本，需要在数据库中添加一个表，但我想添加检查表是否已创建表。但我的脚本给了我这个错误信息：

Msg 102, Level 15, State 1, Line 7
Incorrect syntax near 'ON'.
Msg 2714, Level 16, State 6, Line 1
There is already an object named 'DeliveryChargeRegion' in the database.
Msg 102, Level 15, State 1, Line 2
Incorrect syntax near 'END'.

Answer 1

IF not  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[TABLENAME]') AND type in (N'U'))

begin

-- Create table.

end

GO

Answer 2

此代码类似于SSMS生成的代码：

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[TABLE_NAME_HERE]') AND type in (N'U'))
BEGIN
    -- CREATE TABLE HERE
END

Answer 3

另一种方法

if object_id('tablename') is NULL
BEGIN
    CREATE TABLE tableName

END

sys.objects方法没什么问题，我发现上面的内容更容易编写和阅读......
