Is it possible to exclude white space from creating records using UNPIVOT

Question

SELECT
        FROM
            Table1
            UNPIVOT EXCLUDE NULLS
                NEW_COLUMN
                FOR COLUMN_NAME IN
                   FIELD1, field2, --------------FIELD20
            )I don't want to create row for whitespace (empty value) in any of field1-field20 columns. Row should create for each of value present in any of FIELD1-FIELD20. Is it possible to exclude white space from creating records using UNPIVOT? I am just looking for syntax if there any. thanks

Hi,
Sorry, it's very unclear what you want.
Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).
See the forum FAQ {message:id=9360002}
Have you tried the the UNPIVOT EXCLUDE NULLS option? See the SQL Language manual for details.
It that doesn't do what you want, then you may need to UNPIVOT in a sub-query, generating more rows than you want, and use a WHERE clause in the main query to remove the unwanted rows.
