您可以使用 not carat ^ 和 NOT LIKE 表达式执行此操作.
You can do this with the not carat ^, and a NOT LIKE expression.
所以你说,哪里不像非字母数字;) 这适用于标准数字 &字符:
So you say, where not like not non-alphanumeric ;) This works for standard numbers & characters:
declare @var as VARCHAR (150)
select @var = '123ABC'
if (@var NOT LIKE '%[^a-zA-Z0-9]%')
print 'OK'
else
print 'Not OK'
感谢 Martin 的整理提示,如果您希望将 ý 等字符视为非字母数字,请添加到 COLLATE 中,如下所示
Thanks Martin for the collation hint, if you want the characters like ý treated as non-alphanumeric add in the COLLATE as below
declare @var as VARCHAR (150)
select @var = '123ABCý'
if (@var NOT LIKE '%[^a-zA-Z0-9]%' COLLATE Latin1_General_BIN )
print 'OK'
else
print 'Not OK'
