    Good day!
    I am trying to data from a table with a column that has a column called remarks. This column contains varchar2 character type and is very large. most of the records have comments in ‘remarks’ column more than 2000 characters. So when I query them, they create multiple records to accomodate the remarks section.
    Can you please direct me on how best to prevent this comment section from creating multiple records?

    Thank You,
