To get the result of a SQL count() or other query that
returns a single row, you can use db_1row instead of db_foreach. It
looks like this (and does not have a loop body in { } ):
db_1row s_row "select sid, sname from chuck.s where sid=99"
|
|
To allow for optional input fields, specify a 0 for the
automatic error checking argument to set_the_usual_form_variables like
this:
set_the_usual_form_variables 0

An 'insufficient privilege' error message means you have
not issued a Grant to AD. The SQLplus command is 'grant all on
tablename to ad;' and you have to do a grant for each table. |
|
Be sure to issue a 'commit' command in SQLplus to save
your changes and allow access to your revised data. |
|
UltraEdit is available from www.ultraedit.com. |
|
| 3/01 the Cassandracle monitor is at: http://usf-acs.rho.net/admin/monitoring/cassandracle/users/user-owned-objects |
| 2/24 Team accounts are set up.
|
Avoid '&' in your data when using SQLPlus, the
ampersand causes SQLplus to prompt for the value. |

| 2/16 Want to enter dates and times in your table? The Date
format handles both in one column. In your Insert statements write the
values like this:
to_date('2001-02-21 13:10','YYYY-MM-DD HH24:MI') |
|
