PL/SQL :: Native Dynamic Sql
Jan 8, 2013find the below scripts .
drop table test_arp;
create table test_arp
(
first_name varchar2(1000),
last_name varchar2(1000)
);
[Code]....
when i select the above table ,i will be getting the result as shown
first_name , last_name
CONTROL PANEL
ORACLE SEA
WILLIAMS
RAHUL KUMAR
I need to make a table which will be having the following data and structure
col1 col2 col3
CONTROL ORACLE RAHUL
.i.e , depending on the number of not null values in the first column (first_name), i will be creating a table dynamically ,which is going to have as many columns as the number of values and the naming convention is col1,col2,col...........
I designed the below procedure to CREATE OR REPLACE PROCEDURE ARP
AS
C NUMBER:=1;
BEGIN
FOR I IN (SELECT FIRST_NAME FROM TEST_ARP WHERE FIRST_NAME IS NOT NULL)
LOOP
IF C=1 THEN
[Code]...
But when i execute this code , i get the below error
ORA-00984: column not allowed here
ORA-06512: at "ARP", line 17
ORA-06512: at line 1
SQL & PL/SQL :: Querying Through Dynamic Database Links Using DBMS_SQL
Nov 14, 2011I am using SQL Developer.I am self-teaching myself PL/SQL. What I am trying accomplish is to run a select query across many database links at runtime and to insert that query onto a local table. So far, I have only gotten as far as querying the database link names. I am stuck at where my variable calls the database link name. It does not recognize the database link name, and I can't quite grasp the reason why. Below is the first part of my script which does retrieves the column values no problem:
001 SET SERVEROUTPUT ON
002 DECLARE
003 db_link_varVARCHAR2(30);
004 source_cursorINTEGER;
005 destination_cursorINTEGER;
006 src_csrINTEGER;
007 dst_csrINTEGER;
008 rundate_varDATE;
009 instance_name_var VARCHAR2(30);
[code]....
If I break the script down to the bare select query, it will query absolutely fine.If I run the script in its entirety, it will not pick up the variable dbl as a dynamic database link. 02019. 00000 - "connection description for remote database not found"
If I comment out line 031 and prevent the looping of querying of database links (which will only fetch the first value of db_link from dba_db_links), the script will complete and I will have a row inserted into my local table.
I am suspecting it's the looping that is incorrect but I understand it is not going to do anything beyond line 059.

View 14 Replies View RelatedSQL & PL/SQL :: Using Dbms_sql.execute To Build / Execute Dynamic Sql?
Oct 23, 2013I'm working with old code that uses dbms_sql.execute to build/execute dynamic sql. In our case, the user can select varying columns(I think up to 20) with different where conditions as needed.
After building the sql, here's an example
WITH ph AS
(SELECT ph.* FROM po_header ph WHERE 1 = 2),
pf AS
(SELECT DISTINCT pf.order_id, pf.fund
FROM po_fau pf, ph
WHERE 1 = 1
AND ph.order_id = pf.order_id
[code]....
Where table records for
po_header = ~567746
po_fau = ~2153570
and PK "order_id" is a NUMBER(10) not null and a snippet of the code looks like
nDDL_Cursor := dbms_sql.open_cursor;
dbms_sql.parse(nDDL_Cursor, sSQLStr, 2);
FOR x IN 1 .. nCols LOOP
sCols(x) := '';
dbms_sql.define_column(nDDL_Cursor, x, sCols(x), 100);
END LOOP;
nError := dbms_sql.execute(nDDL_cursor);
why when the "execute" statement is fired off the elapsed time takes ~4.5 seconds but If I change "1 = 1" above to "1 = 2" it takes ~.2 seconds. If I run the above query interactively it takes ~.2 seconds. Shouldn't the above query when joining
ph.order_id = pf.order_id
return zero rows back instantly or does the "dbms_sql_execute" do some other type of parsing internally that takes cpu time.

Feb 3, 2008 I want to wrap the source code in oracle, i am able to do it using wrapping utility (through DOS prompt command i.e wrap iname= inputfilename.sql oname=outputfilename.plb).

This above will replaces the original function source code with wrapped code, but here they are concatinating the code manually.

Server Administration :: Setting Up ASM Using ASMLib On Native Linux Multipath Mapper?
Nov 8, 2010I've been trying to setup ASM disks for two node cluster using ASMLib. It's a multipath environment
Quote:multipath -ll

\_ round-robin 0 [prio=0][enabled]
\_ 1:0:1:1 sdl 8:176 [active][ghost]
[code]....
I've been following Metalink note 602952.1, 309815.1 and 605828.1
metalink note 602952.1 states Quote:Note: Keep in mind for ASMLIB disks you will need to use the /dev/dm-* disks instead of the /dev/mapper/mpath* devices since they are present in the partition table ==)> /proc/partitions and ASMLIB will look at that file during the disk discovering phase. If you do not use the disks located at /dev/dm-* then ASM will not be able to discover them. and to create ASM disks with Quote:/etc/init.d/oracleasm createdisk DISK1 /dev/dm-<disk><partition> Also further stating Quote:NOTE: When scanning, only the device names known by the kernel are scanned. With device-mapper, the kernel sees the devices as /dev/dm-XX. The /dev/mapper/XXX names are created by udev for human readability. Any configuration of ORACLEASM_SCANORDER or ORACLEASM_SCANEXCLUDE must use the dm prefix.My environment is RHEL5 and towards the end of the note it says Quote:Note: On release RH 5 the /dev/dm-N devices are not persistent, starting, these devices are no longer created by udev. So release RedHat 5 you can create the ASMLIB disks on the /dev/mpath/<partition> or /dev/mapper/<partition>
Example:
# /etc/init.d/oracleasm createdisk VOL1 /dev/mpath/sata01p1
Or
# /etc/init.d/oracleasm createdisk VOL1 /dev/mapper/mpath2p1
Therefore I created a ASM disk using /dev/mapper path and it is only visible on the node it was created. Even after scandisks on other node it is still not visible when listdisks/oracleasm-discover
I've also tried creating the asm disks with dm-12 option and the same, disk get created but not visible on the other node.
Moreover if I restart the oracleasm restart the disk disappears from the node that it was visible Quote:
[root@db2 ~]# /etc/init.d/oracleasm createdisk vol1 /dev/mapper/mpath6p1
Marking disk "vol1" as an ASM disk: [ OK ]
[root@db2 ~]# ls -l /dev/oracleasm/disks/*
brw-rw---- 1 oracle dba 253, 12 Nov 8 10:22 /dev/oracleasm/disks/VOL1
[root@db2 ~]# /etc/init.d/oracleasm scandisks
Scanning the system for Oracle ASMLib disks: [ OK ]
[code]....
But disk lable is there and could be seen from both nodes on the same partition Quote:
head /dev/mapper/mpath6p1
VOL1ORCLDISKVOL1
My suspicion is on multipath configuration. I've tried both (not at the same time) combinations given below.
Quote:ORACLEASM_SCANORDER="dm"
ORACLEASM_SCANEXCLUDE="mpath mapper sd sda sdb"
and
Quote:ORACLEASM_SCANORDER="mapper"
ORACLEASM_SCANEXCLUDE="mpath dm sd sda sdb"
But still the problem is there, (disks disappears when asm is restarted and never visible on the "other" node).
Impdp Speed Differ From Location To Location
Oct 4, 2013We have taken export expdp backup from prod database (primary database- Data Guard).
1.) Import impdp is very slow 10GB/Hrs on staging database (Data Guard MAXIMUM AVAILBILITY)Since Server configuration, database version and configuration, operating system everything are same as production. No blocking, locking or waiting sessions
2.)import impdp is fast 90GB/Hrs on Test standalone database and this test database is running in NOARCHIVE LOG mode with oracle standard version after that no more difference.
CPU,Memory,network and disk I/O are look normal while importing on both databases.why that much difference on import.
Reports & Discoverer :: Bar Code Reader Will Readout Code
Feb 12, 2009I have no knowledge about Barcode. The problem is an issue of Loyalty Cards of a Hotel and Restaurant to various customers and then these cards will be presented by the customers time to time in the Hotel as well as Restaurant. The Owner of the Hotel and Restaurant wants to generate separate barcode for each card and when this card will be presented then the bar code reader will readout the code and the system will calculate the amount of discount/rebate. Because if the data entry operator enter the code of the card through key board the it will be a chance of leakage or misuse of that card.
View 8 Replies View RelatedSQL & PL/SQL :: Compare SVN Source Code With Production Code In Database
May 30, 2012I have to compare my SVN source code (packages, views etc) with the production code in the database like views etc (actually we are not sure that what we have in the svn is the final version of production code, we have objects created in the production database, but we don't have latest scripts for that. we have to deploy the svn code in the UNIX box).
So here the comparison is between the OS files and the database objects.
I thought I would get scripts of all the packages, views etc from the production database by using DBMS_METADATA or some utility and save the code in OS files then compare one svn file with OS file manually by using some comparison tools e.g toad provide one comparison tool.

How To Catch Null Value With C# Code
Jan 5, 2010how to catch a null value with C# code?
My Asp.Net/C# application is connected to an Oracle database where it retrieves database values and also values calculated/returned from Oracle functions. My problem is that sometimes an Oracle function I calling returns a null value because of not correct input parameters which will cause Oracle function to (I think) return an null value. My problem and question is how to catch/obtain if he Oracle function returns a null value? Oracle function should return a decimal value if correct input parameters. Below is my row of code that crashes when Oracle function returns a null value in case of incorrect input parameters.
decGrossFreightRevenue = (decimal)(OracleNumber)cmdCalculateRevenueCall.ExecuteOracleScalar();
how to change my code to catch a null value and avoid a crash. I have tried several checks (if statements) without success.
SQL & PL/SQL :: Code For RESULT Column?
Aug 4, 2011I have the following data (columns IDx, STARTx and DURATION) and want to create the column RESULT. Example:
create table zTEST
( IDx number,
STARTx number,
DURATION number,
RESULT number );
insert into zTEST (IDx, STARTx, DURATION, RESULT) values ( 1 , null , null , null );
[code]...
The logic behind the table is like this: when there is a Start-ID and a Duration, the field Result shall show the Start-ID for the next records (Duration period). Even if there is a new Start-ID in row 9, it is ignored since threre is already a current signal from row 6 which is still running.
What is the sql code for the RESULT-column?

203 26/06/2012 1000
this is the table i have in which repeated itemids for different dates,for example itemid 205 and 203 comes 2 times because that item was consumed again and again in a different date. like this the table data has more than a 20 thousand records;
In which i need to select the last updated dates itemid from this table, because same item id could be consumed 'n' number of times so i need to select it as per the last date or latest dates itemid from this table for each and every item, so how can i select it?
