Conditional column selecting column from other table
Anonymous
Got it! So you can merge the tables with a LEFT JOIN. Then you can create a new conditional column with the format:
IF [new column] = null THEN output=Column1, ELSE [new column]
]

I also want to change the null that I will have in the merged table by the Customer name (entity name) from Table A.

So do you have some customers in Table B that are not in Table A? If so, since you are using a left join, those customers would not appear in your merged table.

But I need to have a complete table by short name or entity name.

I think I am confused as to what your two tables contain. Does Table A overlap with Table B? I know that there are entries in Table A that are not in Table B but are there also entries in Table B that are not in Table A?

I think now will be easier to understand.
