Retrieve Data From A Table For Certain IDs
Apr 7, 2013I 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 :: Retrieve Hierarchical Data From Same Table
Nov 10, 2011Look into the below table:
TABLE :- EMPLOYEE
________________________
| ID | SUPERVISOR |
|_______________________|
| A101 | B102 |
|________|______________|
| | |
| B102 | C104 |
|________|______________|
| | |
| C104 | D108 |
|________|______________|
| | |
| D108 | E104 |
|________|______________|
Here B102 is supervisor of A101 and C104 is supervisor of B102 and so on. I want to get this data into new table in below format
TABLE :- Hierarchy
________________________________________________________________
| ID |SUPERVISOR_1 |SUPERVISOR_2 |SUPERVISOR_3 |SUPERVISOR_4|
|______________________|_____________|_____________|____________|
| A101 | B102 | C104 | D108 | E104 |
|________|_____________|_____________|_____________|____________|
| | | | | |
| B102 | C104 | D108 | E104 | NULL |

| D108 | E104 | NULL | NULL | NULL |
|________|_____________|_____________|_____________|____________|
| | |
| E104 | NULL | NULL NULL NULL
|________|_____________|_____________|_____________|____________|
I want to insert 1st two rows into Hierarchy table, then I would like to update Supervisor_2 to Supervisor_4. Here I don't want to use 'CONNECT BY PRIOR', as it take more time to execute (there are millions of records).SQL code for same.
SQL & PL/SQL :: How To Retrieve Data That Does Not Exists In A Table
Dec 13, 2011I 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, 2009I 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.

I've plan to so this by create a trigger in main_table. my problem is my main table have a lot of fields and I can't write a code to control it 1 by 1 like :
if old.A <> new.a
insert into history("A",old.A,new.a)
if old.B <> new.B
insert into history("B",old.b,new.b)

I decided to select column name from the data dictonary using this SQL:
SELECT column_name FROM user_tab_columns WHERE table_name = '<<Table Name>>';
and then do a loop over the resultset and use the column name I've got , like this (its just an idea, may be not a write syntax):
BEGIN

FOR i IN 1..:result.COUNT LOOP
if ld.colname[i] <> :new.colname[i]
INSERT INTO history

but I can't write a "old.colname". I try with " old.'colname' ", " ld.'colname' " but it won't work.how to create a history file like I've describe.

Jan 9, 2013I have a table with around 650,000,000 rows and we need to delete about 60,000,000 rows at the end every month and same amount of rows accumulate throughout the month. The deletion usually takes overnight to delete. We are using 10r2 in IBM AIX. The procedure we are using to delete is:

begin

Performance Tuning :: Oracle Server - Analyze Table In Main Database
Jul 13, 2010I have a procedure which mainly run queries on a Table which has nearly 9.5 million recodes. This procedures takes nearly 15 min to complete execution on our main database. I exported and imported the schema to our backup database and the same procedure just took 3 seconds to complete.
I tried to analyze the table in our main database and tried to execute the procedure again but did not show any improvements. ANALYZE TABLE DN_ACTIONS COMPUTE STATISTICS;
I am not sure computing the statistics for all the tables in the schema will work. I also checked there is enough disk space where oracle data files are stored. I am also turning on the sql trace to see what sql statements in the procedure is taking longer time.
Data Archive Script Is Taking Too Long To Delete A Large Table
Aug 8, 2013We have data archive scripts, these scripts move data for a date range to a different table. so the script has two parts first copy data from original table to archive table; and second delete copied rows from the original table. The first part is executing very fast but the deletion is taking too long i.e. around 2-3 hours. The customer analysed the delete query and are saying the script is not using index and is going into full table scan. but the predicate itself is the primary key,More info below
