Question

I have a column of data that contains a percentage range as a string that I’d like to convert to a number so I can do easy comparisons.

Possible values in the string:

'<5%' '5-10%' '10-15%' ... '95-100%' 

I’d like to convert this in my select where clause to just the first number, 5, 10, 15, etc. so that I can compare that value to a passed in ‘at least this’ value.

I’ve tried a bunch of variations on substring, charindex, convert, and replace, but I still can’t seem to get something that works in all combinations.

Any ideas?

Answer 1

Try this,

SELECT substring(replace(interest , '<',''), patindex('%[0-9]%',replace(interest , '<','')), patindex('%[^0-9]%',replace(interest, '<',''))-1) FROM table1  

Tested at my end and it works, it’s only my first try so you might be able to optimise it.
