How to find the position of first numerical value?

Wed, 18 Feb 2015 09:34:09 GMT

Hi All,

I have a below requirement to be accomplished,

In a string I need to find the position of first numerical value from left.

Examples:

'asdf1234',

'asdf 1234',

'computer 23technology'

From the above strings I need to get the output of 5,6,10 respectively, which are positions for the first numeric from left.

The above are the example strings and it could vary in any manner.

Could anyone please help me out on this?

Thanks & Regards,

Karthikeyan A R.

Load *, index(Example,left(keepchar(Example,0123456789),1)) as tmp1 inline [
Example

Hi,

from the internal help I gather that you can pass several characters to look for to the INDEX() function? Then you could write like

>>> INDEX([field], '0123456789') <<<

and that should return the position of the first occurence of any of these, no?

Give it a try.

Thank you for your reply.

But the strings with numeric will be dynamic. We cannot exactly say whether the number is 1 or 2 or 3.

So first we need to find the first number in string from left and then its position.

Hi,

I have tried the above but it is not working as I expected.

The below function works,

Index('text01234567890','0123456789')

But not with this: Index('text0123','0123456789')

Thanks
