What is the PLSQL command that will count the unique entries in a
column?

So if the table has this column ACCOUNT
ACCOUNT
1
1
2
3

The answer would be 3.
I tried "Select count unique ACCOUNT from table" and that didn't work
"Select unique ACCOUNT from TABLE" works to list all the unique ones,
but I just want the count of unique ones.

Thanks.

Hi bbsch1245-ga,

You were close with your try of "Select count unique ACCOUNT from
table"

The proper format is "Select count(distinct ACCOUNT) from table"

Research technique:
sql select count
sql select count(*)

A great sql tutorial can be found at http://www.w3schools.com/sql .  
I reference it all the time.  In addition, an example of select count
can be found at http://forums.devshed.com/t58759/s.html

If you need a clarification, don't hesitate to ask,

Thanks!  I especially appreciate the pointer to the sql tutorial.  If
there's a tutorial specifically for Oracle PL Sql do let me know. 
Thanks,
