define [SQL*Plus] define sets a user variable or displays its value. The following command sets the variable varname to foo. define varname=foo.

The following command displays the value of varname. define varname.
The column already exists and currently will not allow null values. This is a distributed application (everyone has their own different MDB file) so I need to be able to modify the column through T-SQL. My statement to try and do this is: ALTER TABLE clients ALTER COLUMN state VARCHAR(255) NULL. However, when I view the table after running that SQL statement the table is still not allowing null values. Please don't tell me I need to drop the column before allowing null values.
