take the phone number, convert out any puncutation (-, (, )), divide by 9100000000. If the dividend is >1, you have a 10 digit number> 9100000000. If you need a fixed range (such as all 91 - 94 numbers), define the maximum dividend by dividing 9499999999 by 9100000000. If you then divide the phone nmber and get a result less than 1 and greater than the ratio defined above, the number is out of range.

  1. SELECT t.phoneno FROM target t, source s WHERE substring(t.phoneno,0,4)=+91

  2. AND +91||s.phoneno=T.phoneno

First Thing: If phone_num is type numeric, + is not allowed.
Second Thing: If phone_num is varchar, and the length of the phone_num is 8 in source, if you want +91 to be appended in the beginning the length will become 11 in target. Not 10.
Considering length in target is 11 below query returns all the phone numbers having +91 in the beginning and having length 11.
