Question

Im in a position where I cannot alter the table structure of my database and I have Ambiguous Column Names in [table1] and [table2]. I do not need to use any fields from [table2] but its existence is necessary to relate to another table. Is there a way that I handle this?

Answer 1

Every time you refer to one of the ambiguous column names you should specify the table name or alias.

SELECT ...
FROM [table1]
JOIN [table2]
ON [table1].ambiguous_column = [table2].ambiguous_column
AND ...
