MySQL Alphanumeric to integer

Hi folks,

typeset -i A12

But, I need your advice to change the values like 1A2 or 12A into integer.

Thanks in advance.

Depends on whether you want 1A2 to return 1, 2 or 12

If the latter,
sed 's/[^0-9]+//g'

If the former,
 perl '@ints=$ARGV[0]=~/[0-9]+/g;print(join ", ", @ints),"\n";'

Thanks for your reply.

I dont not want to split the value.I want it as whole 1A2 into integer.

I want to use this value in array index as belue

Array[1A2] - now i am getting error like "bad number"

So i need to change 1A2 into integer.

Please advice.

Is it hexadecimal?

Depending on your shell and system, you may be able to turn it into decimal like


If it's not hexadecimal, you'll need to explain how you want the numbers interpreted, since arbitrary string to integer isn't straightforward.
