But, Oracle designed the COUNT function to help us count records in a table. What's wrong with it?

hi,

analyze your table and then query the user_tables <num_rows> column.

Do a SELECT * and then read the line that says "x rows selected"

In select clause add rownum dummy column and then last rownum is the number of your rows

If you want just a single line of output (hey, displaying all those records can be tedious) do a delete <your_table> and read the line x rows deleted as joy_division suggested
