SQL Conversion Error on Inner Join Statement - Not Converting Anything - sql

Question

I've used this site for research for years but can't figure this one out from my research. Getting the following error:
Conversion failed when converting the varchar value '38221.0' to data type int.
This '38221.0' correlates to the 'CP.DNCP_PATIENTID' from the below code:
SELECT PAT.V51_PRSNPERSONNUMBER AS PSNNMBR,

As I'm not converting anything, I'm unsure why I'm getting this error. I've used a variation of this coding on many projects and never received the error. I appreciate any help. Thanks!

Answer 1

Sorry, I got it. I was thinking it was in my INNER JOIN but it was in one of the other joins. I was joining a PERSONNUMBER to a PERSONID. I fixed it and everything works smoothly now. A case of staring at it too long and not seeing what's right in front of you. Thank you for your time.

Answer 2

Try CONV(N,from_base,to_base),it converts numbers between different number bases. It returns a string representation of the number N, converted
from base from_base to to_base
