that error message is produced when a column name exists in more than one table and is not properly qualified by its table name

all of your coluumns appear to be properly qualified by their table names

are you sure this is the query that produced the error message?

3

Yes, I put this query in the Oracle SQL Developer and it produce this error when I run it.

4

did it give any indication as to which column is the ambiguous one?

5

It was my careless mistake, one of the column name is wrongly spelled.
Thanks for explaining.
