如何选择0作为前缀的值，例如00-09

Question

My column called 'abstract' varchar(2) utf8_general_ci has the following mixed values:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ... 98, 99,
00, 01, 02, 03, 04, 05, 06, 07, 08, 09,
A, B, C, D, E, F, G, ... X, Y, Z

How can I exclude the values 0-99 and AZ in an select query without explicit nomination. I do only need the values 00-09 . I tried the following query:

select * from table where abstract REGEXP '[^0-99]' and abstract REGEXP '[^AZ]';

But the REGEXP '[^0-99]' removes also the 00-09 from result.

Answer 1

这应该做：

  select * from table where abstract like "0%" and abstract != "0";

Answer 2

尝试这个：

select * from table where abstract like %'00-0'%;
