Deleting information in a query

I have a table that is setup like this
ranking Company Total Revenue
1 ABC 123,456
What I want to do is have a delete query(or something) that just deletes the
contents of the Company and the Total Revenue columns and keep the column
ranking with its information.
The SQL coding is below but that deletes all the rows hence deleting the
ranking information.
DELETE CompanyOneYr.Company, CompanyOneYr.[Total Revenue]
FROM CompanyOneYr;

The ranking column is a permanent set of numbers from 1 to 50
Can someone please advise

What you want to do is update the columns:

update CompanyOneYr
set Company = ''.[Total Revenue] = Null

The DELETE command deletes the whole row. What you want is the UPDATE
command. Ex:

UPDATE CompanyOneYr
SET Company = NULL,
[Total Revenue] = NULL

This will set the values for columns "Company" and "Total Revenue" to
NULL values (blanks) for the entire table. If you just want to clear
certain rows add the WHERE clause to the command:


UPDATE CompanyOneYr
SET Company = NULL,
[Total Revenue] = NULL
WHERE ranking IN (1,5,7)

This will NULL the columns for rankings 1, 5, and 7.
