SQL Server查询以添加具有默认值的列

Question

I'm trying to change my SQL server database by adding another column to a table with 0 as a default value.

I thought this script worked in the past (for another table), but now I have an error when I try to execute the script

The script

ALTER TABLE Whatever
ADD WhateverColumn tinyint NOT NULL 
DEFAULT(0)

The errors

• On hovering mouse over "NOT": Incorrect syntax near 'NOT'. Expecting 'TO'
• On hovering mouse over "0": Incorrect syntax near 0. Expecting '(', or SELECT

Anyone knows what's wrong with this?

Answer 1

Try this:

ALTER TABLE Whatever
ADD WhateverColumn tinyint NOT NULL DEFAULT 0

Answer 2

也许你使用的“Whatever”作为表名有未闭合的引号，甚至是“WhateverColumn”（你把它放在这里作为代币，我得到它）我有这个问题，甚至是“WhateverColumn”的实名是一个保留字？

Answer 3

@SammuelMiranda has just asked the same just now. It matters if you are using reserved keyword as table or column name also.

Answer 4

As I expected, updating my SQL Server Management Studio to version 17.8.1 solved my issue.
After updating, I was able to run this command without any problem.
