Can we have a number as column header in a table?

Question

Create table A1
(
    seq_no int, 
    1100 varchar(20)
)

With this query, I am getting an error

Incorrect syntax near 1100

How to overcome this in SQL Server?

Answer 1

您需要将以数字开头（或名称中带有空格）的列名称放在方括号中，如下所示：

Create table A1
(
    seq_no int, 
    [1100] varchar(20)
)

或者只是简单地避免使用这样的列名-那些列名将在整个编码过程中继续引起头痛和悲伤- 尽可能避免这种情况！
