I need to whip out a PL/SQL procedure real quick today and have a quick
question for fellow-listers ( since today is Friday, hopefully I don't get
RTFMed on this one :) )
The purpose of my procedure is to collect stats from v$session_wait
periodically ( every second
How would you take the same string /dir1/dir2/test/file.out, and return
file.out. Assume you do not know where the last '/' is or how many there
are. What I need is a reverse instr function. Find the last occurrance of
'/', not the first.
Can it be done in sqlplus???

Hi,
I have imported a text-file into a table in the database. Now I find that there are
many bad things in some fields, for instance there is a ? instead of the value 0.
Can anyone give me a good example on a procedure that loops through a table and if
found a ? in some fields, replace it
update table
set dodgy_field = replace( dodgy_field, '?', '0' )
/

Thanks Raj and others. That definitely leads me to the right direction.

The syntax is:

Hello all,
Can someone tell me whether or not there is a way
do this in SQL?
I want to select some data given a certain date
range,i.e where some_date between start_date and
end_date.
Is there a way to group the output by week?
In other words, something like:
SELECT column_a, column_b,
You can do something like
select to_char(date_column,'YYWW'), count(*), sum(other_column)
from table
where date_column between date1 and date 2
group by to_char(date_column,'YYWW')
where WW returns the week of the year ( 1 to 53)
keeping in mind, of course, that you must include in the group by
some_date_column BETWEEN :start_date and
:end_date
group by to_char(some_date_column, 'YYWW')

Hello all,

Another option is to create a table with a large varchar2 column and insert
the data row by row.
You can then spool a SELECT from that table to a file.
e.g.
create table hold_output
(mytext varchar2(4000)
tablespace ts_small;

Hi ...
you can go for UTL FILE feature of Oracle PL/SQL, it is very handy while handling
large amount of data that DBMS_OUTPUT can't handle due to the buffer size constraints.
Cheers,
Bagchi.

Hi,
This is my first attempt at writing a PL/SQL procedure. Everything works
fine, except I have a firly large table I am running against. I am trying to
display my output with DBMS_OUTPUT.PUT_LINE. I have set the buffer size to
100, apparently the maximum value, but it still isn't
Use the UTL_FILE package and write the results to a temporary file.

Bill,
Try pushing the output directly to a file using calls to the
Utl_File supplied package. That would allow you unlimited
spooling capacity.
If you really want to use DBMS_Output, you might try (but I
don't know if it would work) to call DBMS_Output.Disable
then DBMS_Output.Enable(100)
