SQL & PL/SQL :: Unable To Retrieve Rows From A Table

Mar 7, 2012

I have created a table called ct_temp and it's structure is:

create table ct_temp(id char(2),srs number(3),amt number);

Result : Table Created

I now insert the following rows into the table:

id srs amt

1 62 30000
2 65 50000
3 65 70000
4 65 80000
5 62 16000
6 65 10000
7 65 100000
8 65 10

Commit

Then I issue the following query to retrieve data based on a specific criteria (Actually I have condensed the table and data because in Production, I have large number of rows; so for simplicity I am using 8 rows with one table)

criteria : I then want to retrieve the following:

for srs = 62, all values that is greater than 10,000

Answer: select decode(srs,62,ab.amt)temp1 ,decode(srs,65,ab.amt)temp2 from ct_temp ab

where decode(srs,62,ab.amt)>10000

Works like a charm and retrives the results.

Now comes the big issue

I want to retrieve the values for srs = 62 which is greater than 10,000 and at the same time I also want to retrieve the values for srs = 65 which is less than srs = 62.

Typically I wrote the query as:

select decode(srs,62,ab.amt)temp1 ,decode(srs,65,ab.amt)temp2 from ct_temp ab
where decode(srs,62,ab.amt)>10000
and decode(srs,65,ab.amt)<decode(srs,62,ab.amt)

I should atleast get one row for srs = 65 which is id # 8 but it displays blank rows or "no rows returned".

I am actually preparing a ad-hoc report for the business analyst and stuck at this step due to which I am unable to proceed any further. I have used DECODE function because of the requirement specified by Business Analyst.

I have tried the following in the office:

using EXISTS operator = no luck
using INLINE VIEW = no luck

Is there any way around?

SQL & PL/SQL :: Unable To Retrieve Multiple Values / Possibility From A Table?

Jun 1, 2010

I have a table called table1 and its structure is as follows:

rtrn_id number,
entp_abn number,
litm_line_item_nbr number
country_code varchar 2(10)

I am trying to find retrieve value/row where for a particular rtrn_id , the possibility of having a country code of "CA"(for Canada) and "US" or "HK" (US or Hong Kong respectively) exists.

I framed my query the following way and it does not retrieve any result in Production and I believe there are a few values/rows in the "table1".

The query framed is:

Query 1:

SELECT rtrn_id,entp_abn,litm_line_item_nbr,country_code
FROM table1
where schd_version_yr = 2010 and prog_program_cd = '01'
and sched_nbr = '000' and (litm_line_item_nbr = '023' and country_code 'CA')
and (litm_line_item_nbr = '016' and country_code = 'CA')

The above query does not retrieve any rows

Where as if I run a query individually it retrieves tons of rows

(Individual query :

SELECT rtrn_id,entp_abn,litm_line_item_nbr,country_code
FROM table1
where schd_version_yr = 2010
and prog_program_cd = '01'
and sched_nbr = '000'
and (litm_line_item_nbr = '016' and country_code = 'CA')

-----Retrieves tons of rows as the country code = Canada for line item # 16

SELECT rtrn_id,entp_abn,litm_line_item_nbr,country_code
FROM table1
where schd_version_yr = 2010
and prog_program_cd = '01'
and sched_nbr = '000'
and (litm_line_item_nbr = '016' and country_code 'CA')

-----Retrieves tons of rows as the country code IS NOT Canada for line item # 23.

There is a possibility that there are rows that have country Code as Canada and not Canada for a particular ID whose line item numbers could be 16, 23.. is there any better way to frame my Query1 to retrieve values/rows?

PL/SQL :: How To Compare Two Rows And Retrieve The Values

Aug 15, 2012

I have two tables which have identical schemas, one table (tbl_store) is used to hold the latest version, and the other table (tbl_store_audit) holds previous versions. When the latest record is updated, it is inserted into the tbl_store_audit table as a revision, and the updated details are used as the latest record.

For example: The latest version is held in tbl_store, however the tbl_store_audit may hold 5 records which are the past records used before changes were made - these are seen as revisions.

I want to be able to compare what has changed between each revision in the tbl_store_audit table. For example: Out of the 10 columns, the change between revision 1 and revision 2 was the size from XL to XXL. The change between revision 3 and revision 4 was the size XS to M and price 4.99 to 10.99, and so on.

Eventually i will create an APEX report that will show the user the revision number and what was changed from and to.

I seen in a previous post i need to note my oracle version: Oracle version 10.2.0.4.0

How To Format Date To Retrieve Rows Result

Jun 6, 2008

I am trying to retrieve all rows with the date of May 23rd, 2008. Our data is stored with the date and time.

How do I format the where clause so that the time is taken off? I am still a newbie with oracle and what I have is this:

Select Distinct Table1.*, Table2.*
from Table1, Table2
where Table1.file_name = Table2.file_name
and Table1.downloaded_date = Table2.date_loaded
and downloaded_date = '23/May/2008'

Of course, it's the last line not working because I don't know how to format it and no rows are retrieved when there are definately May 23rd rows stored in there.

Retrieve Data From A Table For Certain IDs

Apr 7, 2013

I am writing a SQL inside an application to retrieve data from a table for certain IDs or for All employees based on the user's input. I create a variable :SELECTION for the where clause. When I run the SQL, I receive the error of missing right parenthesis. There is no error if I hard code the IDs.

If the input is 'All' -> the variable :SELECTION is blank so if the SQL :

select name, address, ID from employee :SELECTION

will be

select name, address, ID from employee

If the input of users ID as '1234','9999' - > the :SELECTION = ' where ID in (:VARIABLEID)'
:VARIABLEID = '1234','9999'

so the SQL:
select name, address, ID from employee :SELECTION

should be

select name, address, ID from employee where ID in ('1234','9999')

However, I got the missing right parenthesis error. I suspect it is something with the single quote, so I tried different ways, but it is still not working.

SQL & PL/SQL :: How To Retrieve Data That Does Not Exists In A Table

Dec 13, 2011

I have the following table with the some sample data:

|| Filename || receiving_site || originating_site ||
| fileA | siteA | HQ |
| fileA | siteA | siteA |
| fileB | siteA | HQ |
| fileA | siteB | HQ |
| fileA | siteB | siteB |
| fileB | siteB | HQ |
| fileB | siteB | siteB |

The table works in such way:

1. For each of the Filename, if originating_site is not the same as receiving_site, it means that the file has been sent to receiving_site but has not been acknowledged received yet.

2. For each of the Filename, if originating_site is the same as receiving_site, it means the file has been sent and received by the receiving_site.

My task is to list out all the Filename per receiving_site that has been sent, but not received yet by the receiving_site. For example from the sample data above, I am expecting to see that siteA, fileB has not been received yet.

How can I do that? I had tried MINUS and NOT EXISTS command, but I am just not able to get the result that I want.

Table Locking When Many Users Retrieve Data

Sep 2, 2009

I have a "select ... into" in my PL/SQL and it doesn't retreive any data(I suppose just certain columns because if it doesn't retreive a row then the PL/SQL should throw an error) when there are many users accessing this table. It shouldn't be some table locking right? Because if it is, it should wait until the table is available then it will retreive data. Currently it just proceeds with the PL/SQL and selecting nothing in that query. what details should I look at to trace the cause of this problem.
