How to build Link_Only when multiple different column names

[eryabko]

Hello,
I need some help with the following use case. I have 2 data frames that I am trying to link;
ACB ['ACB_CR_ID', 'ACB_RID', 'ACB_R_DATE', 'FIRST_NAME', 'LAST_NAME', 'DATE_OF_BIRTH', 'Program']
&
PRG ['PRG', 'PRG_ID', 'PRG_FIRST_NAME', 'PRG_LAST_NAME', 'PRG__DATE_OF_BIRTH']

I want to write a link_only version, where I fuzzy match on ACB.'FIRST_NAME' =PRG.'PRG_FIRST_NAME' and ACB.'LAST_NAME' = PRG.'PRG_LAST_NAME' and ACB.'DATE_OF_BIRTH' = PRG.'PRG__DATE_OF_BIRTH'. I tried to read the documentation but I can't seem to wrap my head around how to structure this. The biggest issue is that the two dataframes' column names don't match.
Thank you
