a. File size is small:
Read each line from the file and store all the columns as a row in a
pl/sql table.
Once you are done reading the file, take the first element and compare
with the first column of all the remaining rows.
b. File size is big:
Do the above, but instead of storing in a pl/sql table, create a temp
table.
