I have tried several different things with none providing the correct results. Any help is appreciated.

I have the following:
Table A Table B
Pallet_No Pallet_No
Qty Qty

I need to return:
- All of the Pallet_No's from Table A that are not in Table B
- All of the Pallet_No's from Table B that are not in Table A
- All the Pallet_No's where there is a difference in Qty b/w Table A and Table B.

Thanks for your help.

Oracle table design help

johnbach — Wed, 28 Oct 2009 05:47:22 GMT

I have around 2 million vouchers of some fixed denomination (say 10 and 20)

create table vouchers(pin varchar2(20) primary key ,amount number,status char(1),extra_value number);

create index IDX_AMOUNT_STATUS on vouchers(amount,status);

Typical values

amount,status ,count(status)

10     N       1000000       

10     U        700000       

20     N        300000

For each payment transaction,I fetch one voucher wrt.transaction amount and mark it as used
(So it will not be used for any other transaction)

UPDATE vouchers SET status='U' 

 WHERE amount=:txn_amount AND staus='N' AND rownum=1

 RETURNING pin,extra_value INTO :pin,:extra;

I have 10 parallel threads processing incoming transaction. I am expecting 30 transactions per second.
Initially the update takes 0.002 millisecond but after few hours it reaches 2 seconds.

I even tried with partitioning table also(status N one partition and defalut another partition).

Platform details
Linux RHEL 5
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production

Suggestions please.

outputting too many

christiangirl — Sun, 18 Oct 2009 22:06:01 GMT

I am just starting to learn sql and have to questions from my homework assignment.
The first is this:
Write a query which will project the average rental price and number of such videos for videos of Classic movies --- BUT! You must write this without explicitly using the category code for Classic movies; you must use the name 'Classic' in your query instead. Rename the columns to be "Avg Cost - Classic" and "# Videos - Classic", respectively, using precisely these spaces and case.

The code I wrote is:

select avg(vid_rental_price) "Avg Cost - Classic", count(*) "#         

Videos Classic"

from movie_category, video

where movie_category.category_code =

        (

          select category_code

          from movie_category

          where category_name = 'Classic'

        )

      and vid_rental_price <

      (

        select avg(vid_rental_price)

        from video

      );

But count is outputting a larger number then it is supposed to. I think it is counting all of the rentals, not just the ones labeled classic. But I am not sure how to fix this.

The second question is:
Using a join, (and NOT using ANY nesting or sub-selects), project the last names, first names, and date the video was due for clients who have ever rented the video with ID '130012'.

and my code is:

prompt 2-5

select distinct client_lname, client_fname, date_due, vid_id

from client, rental

where rental.vid_id = '130012';

It is outputting more rows then it should, and outputs that all vid_id's are 130012. I think this has to do with the join, but am not sure how to do this without a join.

Thanks!

INSERT sql statement for DateTime

dotNetDummi — Fri, 16 Oct 2009 01:59:00 GMT

Hi all,

Is it possible to insert a SQL statement where I specify the time, and not the date. I do need the date, but I want it to be the current date when I run the insert statement. The time got to be fixed.

For example,
Insert into xxx
Values(current_date + '12:00:00');

Anyone have any idea if SQL allows this?

I look forward to your reply.
Thanks in advance.

Trouble with querying in Oracle using SQL

I am stumped. I have tried numerous versions of this code, but this one in particular makes the most sense to me. Please help me if what is wrong here seems to jump out at you!!

Thank you....

Beginner Oracle Help

Kramer.Cosmo33 — Mon, 05 Oct 2009 18:49:27 GMT

Hi, I just started learning how to use oracle I am suppose to create a table for a school that includes class, instructor, enrolls and teaches.
I've basically understand everything, but my only problem is I keep getting a with my schedule_num in my class table. It is suppose to be a primary key and in the instructions it does say that schedule_number of a class is a unique number. I've tried making it a primary key and it just gives me errors for my enrolls and teaches because they each use schedule_num. Making it a unique number gives me a
unique constraint violated error. If anyone has any idea how to correct this error I would greatly appreciate it.

removing first blank line in csv file

axeeffect2002 — Mon, 21 Sep 2009 16:43:20 GMT

Hi,
I have written a sql script which takes the rows from a table and writes it to
a .csv file.

The script is as follows:-

 set feedback off;

 spool output.csv;

 set heading off;

 SELECT username||','||profession from users;

 spool off;

This works fine but output.csv contains a blank line at the top.
How can I get rid of that blank line?

Thanks in advance

DISTINCT on One Column Only

Hello,
I've been trying to find a way, using Oracle Express, to return more than one column but have only one column be distinct. The following will make all three columns distinct. I want only the Job_ID column to be distinct. Can this be done in Oracle?

SELECT DISTINCT Job_ID, Employee_ID, Last_Name

Help with SQL query

Jammie — Thu, 10 Sep 2009 03:39:22 GMT

Hi there,

I'm trying to write a SQL query based on the following tables.

create table purch (

integer user_id, *

integer product_id, *

integer item_count,

date purch_date *

);



create table product_categ (

integer product_id, *

integer category_id

)

Could someone tell me how to find the lag between category switches. By this I mean if user 1 regularly purchased from category 1, but then after 3 days of inactivity returned to purchase from category 2, then the time lag in that category switch is 3 days.

I'm trying to do the SQL that creates a result set which contains user_id, prev_category, next_category, days_lag

I'll have to use window function and a self join on this inline view "Y", but I'm not able to figure out how to do that part. Could someone give me some pointers? I did see a lot of examples on window functions but most of them are simple and I'm not able to relate to this one.

I'm still working on this but if you could give me a starting point, that will be great.

(SELECT p.user_id, p.product_id, c.category_id, p.purch_date

FROM purch p INNER JOIN product_categ c

ON p.product_id = c.product_id) Y

Thanks

ERROR at line 1: ORA-01722: invalid number

Roybut — Tue, 25 Aug 2009 16:23:16 GMT

Hi,

I have this view:

DROP VIEW digits;



CREATE VIEW digits

AS

(

    SELECT 

        TO_NUMBER(SUBSTR(rounded_cost, 1, INSTR(rounded_cost, '.' -1))) left_digits,

        TO_NUMBER(SUBSTR(rounded_cost, INSTR(rounded_cost, '.' + 1, LENGTH(rounded_cost)))) right_digits

    FROM roundcost

);

It allows me to create it but the values stored are apparently not valid numbers. When I try select * from digits I get
"ERROR at line 1: ORA-01722: invalid number ".

The roundcost table has numbers like 6.71, 3.54, etc.

Any ideas?

Thanks,

Roy

UPDATE Problem

Roybut — Thu, 20 Aug 2009 17:36:59 GMT

Hi,

I have a table which I want to update thus:

If d_date is has a value and b_date is 30 or more then set d_date as the min value already in d_date. I know that the WHERE EXISTS clause is wrong but I don't know how to make this work.

UPDATE table

SET d_date =

(

        SELECT min(d_date)

        FROM table

)

WHERE EXISTS

        (

                SELECT floor( MONTHS_BETWEEN (SYSDATE, b_date) / 12 )

                FROM agents

                WHERE floor( MONTHS_BETWEEN (SYSDATE, b_date) / 12 ) >=30

      ) 

AND d_date IS NOT NULL
