M Query remove blank rows across all columns

I have a table with four columns, some of the rows are entirely blank but I want to remove only those rows where every column is null. How do I do this?

To remove only the rows where every column is null, you can use the following SQL query:
DELETE FROM your_table
WHERE column1 IS NULL
AND column2 IS NULL
AND column3 IS NULL
AND column4 IS NULL

This query will delete all rows where every column is null. If a row has at least one non-null value in any of the columns, it will not be deleted.

Alternatively, if you want to keep the original table intact and just display the rows with non-null values, you can use the following SQL query:

SELECT * FROM your_table
WHERE NOT (column1 IS NULL
AND column2 IS NULL
AND column3 IS NULL
AND column4 IS NULL)

This query will select all rows where at least one column has a non-null value. The NOT operator negates the condition that every column is null, so only rows that satisfy this condition will be displayed.
