Number data type showing up as # instead of the numbers in SQL Plus.
Please refer to the H_RATE for the issue prevously it was showing up correctly and I have searched the internet and stackoverflow for a simliar issue or answer but none have the same.
Could you help in fixing it so it shows the number instead of #?
回答1:
# is displayed if the value can't fit in the column; from the SQL*Plus documentation:
If a value cannot fit in the column, SQL*Plus displays pound signs (#) instead of the number.
If it was displaying OK and now isn't, I think you've probably set a column format that is too small for the values you're display, something like column h_rate format 9999999999. If you have a 10-digit number that isn't enough, as it needs a character to display a +/- sign.
You can check if that is the case by clearing all column definitions, with clear columns.

Your H_RATE format may be of smaller digits that of the data:
select to_char(123,'99') from dual; --returns ###
but do proper formatting some thing greater than the data:
select to_char(12345,'99,999') from dual; -- returns 12,345
There are various formatting by oracle given here
