如何获取以字段中带有数字的字母开头的数字 OR (SQL SSMS 2016)

Question

Using SSMS 2016使用 SSMS 2016

I have this field:我有这个领域：

+--------+
|   ID   |
+--------+
| ASDFG  |
| S1234  |
| S4321  |
| 123456 |
| 654321 |
| GFDSA  |
+--------+

I want to keep those which are numeric OR starting with S with numbers我想保留那些数字或以 S 开头的数字

Desired output:期望的输出：

+--------+
|   ID   |
+--------+
| S1234  |
| S4321  |
| 123456 |
| 654321 |
+--------+

I tried something like this but didn't work我试过这样的事情，但没有奏效

where Isnumeric(ID) = 1 and ID Like 'S[0-9]%'

I'm hoping it's something small I'm missing so any assistance most welcome我希望这是我遗漏的小东西，所以欢迎任何帮助

EDIT: Just realised that I should've put down OR in the clause.编辑：刚刚意识到我应该在条款中放下 OR。 D'oh!哦！

where (Isnumeric(ID) = 1 OR ID Like 'S[0-9]%')

Answer 1

NB: IsNumeric will lie to you .注意： IsNumeric会骗你。 It would probably be better to combine two Like statements:结合两个Like语句可能会更好：

WHERE ID Like 'S[0-9]%' 
Or ID Not Like '%[^0-9]%'
