Easy match and return help
Hi there.
I have a simple task but just can't figure it out.
This is table1
| countryCode | countryName |
| HK | Hong Kong |
| MY | Malaysia |
| SG | Singapore |
| CN | China |
This is table2
| Country/Region Name |
| HK |
| Malaysia |
| SG |
| CN |
I want to add a column (final_country) in table2 that looks something like this
| Country/Region Name | final_country |
| HK | Hong Kong |
| Malaysia | Malaysia |
| SG | Singapore |
| CN | China |
so basically, the "final_country" column value will depend on "Country/Region Name". If its like HK, SG and CN it should refer to table1 and give me the countryName else give me the original value like "Malaysia"
if the rows of table 1 is unique, then try this code:
NewStep=Table.AddColumn(Table2,"Final_Country",each Table1{[CountryCode=[#"Counrty/Region Name"]]}?[CountryName]? ??[#"Counrty/Region Name"])

Yes table 1 is unique
= Table.AddColumn(#"NoRegisterYesAttend","Final_Country",each #"Country Look Up Table"{[CountryCode=[#"Country/Region Name"]]}?[CountryName]? ??[#"Country/Region Name"])
"NoRegisterYesAttend" is my 2nd table name
"Country Look Up Table" is my 1st table name
but it gives me the error - Expression.Error: A cyclic reference was encountered during evaluation.
wdx223_Daniel it's working now! so sorry , some typo of the column names.
1 question : what does the "?" do in your solution?
use ? to get a null when the result of former statement is a error.
use ?? to get the latter statement result if the former gives a null.
