如何仅在第一个数字是从0到9的数字的位置选择行？

Question

As far as I know I can do something like:

"SELECT * 
 FROM my_table 
 WHERE my_field LIKE '0%' 
 OR my_field LIKE '1%' 
 OR my_field LIKE '2%' ";

Is there a way to achieve this with a regular expression or something like this:

"SELECT * 
 FROM my_table 
 WHERE my_field LIKE [only first char is 0-9]"??

EDIT: The field is not numeric and it can be something like "1 People", "211 Pies" and so on.

Answer 1

Try this

SELECT * 
FROM BadlyDesignedTable 
WHERE AnswerColumn RLIKE '^[0-9]+'

I was wondering if it was even possible to regex in where, found it on google in 30 seconds.
