You could split it up into 3 separate regex to test for each case. 

<code>[a-z]</code>, <code>[A-Z]</code>, and <code>[0-9]</code>

and the results of those matches together, and you can achieve the result you're looking for. 

EDIT:

if you're only looking to match alphanumerics, you should do <code>^[a-zA-Z0-9]+$</code> as suggested by Ed Head in the comments

blocks|key|3133320|text|我的解决办法是找出一个长的表达式，因为我将在所有6种可能性中进行变换--找到的大写字母、小写字母和所需的数字可以排列在字符串中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3133321|%5E(.*[a-z].*[A-Z].*[0-9].*%7C
++.*[a-z].*[0-9].*[A-Z].*%7C

++.*[A-Z].*[0-9].*[a-z].*%7C
++.*[0-9].*[a-z].*[A-Z].*%7C
++.*[0-9].*[A-Z].*[a-z].*)$|code-block|syntax|javascript|3133322|编辑:在结束和开始的时候忘记了.*。|offset|length|style|CODE|3133323|entityMap^0|0|0|F|2|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

My solution is leads to a long expression becuase i will permutate over all 6 possibilities the found capital letter, small letter and the needed number can be arranged in the string:

<pre><code>^(.*[a-z].*[A-Z].*[0-9].*|
 .*[a-z].*[0-9].*[A-Z].*|
 .*[A-Z].*[a-z].*[0-9].*|
 .*[A-Z].*[0-9].*[a-z].*|
 .*[0-9].*[a-z].*[A-Z].*|
 .*[0-9].*[A-Z].*[a-z].*)$
</code></pre>

Edit: Forgot the <code>.*</code> at the end and at the beginning.

blocks|key|3155924|text|有了前瞻性断言，您可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3155925|/%5E(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).*$/|code-block|syntax|javascript|3155926|update似乎mysql不支持查看周围的断言。|offset|length|style|BOLD|3155927|entityMap^0|0|0|0|6|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

With look-ahead assertion you could do like this:

<pre><code>/^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9]).*$/
</code></pre>

update: It seems mysql doesn't support look around assertions.

blocks|key|4016384|text|不幸的是，MySQL不支持查找周围断言，因此您必须为regex引擎拼写它(假设只有这些字符是合法的)：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4016385|%5E(

Unfortunately, MySQL does not support lookaround assertions, therefore you'll have to spell it out for the regex engine (assuming that only those characters are legal):

<pre><code>^(

[A-Za-z0-9]*[0-9][A-Za-z0-9]*[A-Z][A-Za-z0-9]*[a-z][A-Za-z0-9]*
)$
</code></pre>

or, in MySQL:

<pre><code>SELECT * FROM mytable WHERE mycolumn REGEXP BINARY "^([A-Za-z0-9]*[a-z][A-Za-z0-9]*[A-Z][A-Za-z0-9]*[0-9][A-Za-z0-9]*|[A-Za-z0-9]*[a-z][A-Za-z0-9]*[0-9][A-Za-z0-9]*[A-Z][A-Za-z0-9]*|[A-Za-z0-9]*[A-Z][A-Za-z0-9]*[a-z][A-Za-z0-9]*[0-9][A-Za-z0-9]*|[A-Za-z0-9]*[A-Z][A-Za-z0-9]*[0-9][A-Za-z0-9]*[a-z][A-Za-z0-9]*|[A-Za-z0-9]*[0-9][A-Za-z0-9]*[a-z][A-Za-z0-9]*[A-Z][A-Za-z0-9]*|[A-Za-z0-9]*[0-9][A-Za-z0-9]*[A-Z][A-Za-z0-9]*[a-z][A-Za-z0-9]*)$";

<pre><code>SELECT * FROM mytable WHERE mycolumn REGEXP BINARY '[a-z]'

Add additional

I'm using a stored procedure to validate the input parameter. The input parameter must contain a-z and A-Z and 0-9. 
for Example: 
<code>aS78fhE0</code> -> Correct 
<code>76AfbRZt</code> -> Correct 
<code>76afbrzt</code> -> Incorrect(doesn't contain Upper Case A-Z) 
<code>asAfbRZt</code> -> Incorrect(doesn't contain Numeric 0-9) 
<code>4QA53RZJ</code> -> Incorrect(doesn't contain Lower Case a-z) 
 
what Regular Expression that can validate the input parameter like above example,.? 
Many Thanks, Praditha
 
UPDATE Others character except Alphanumeric are not allowed I'm Using MySQL version 5

Regex : string must contain a-z and A-Z and 0-9
