Removing Illegal Characters
Dec 27, 2006
I am working with Oracle 10G, and have been working on setting up little pl/sql checks to make sure that the data that is imported is in the correct format.
The wall I have hit is removing illegal characters from the data I import. I have started to set something up where the string for a certain column must be be made of only there characters:
"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-" (note that there is a - besides just letters) and I may want to add some other characters later. So basically the script will drop or replace any character not found in my definitions with "", thus removing the illegal character and joining the previous and next characters.
I thought for sure there would be a script posted somewhere online that did this but I can't find it and my syntax skills are lacking.

How can I issue this error, I need use also dblink with long type.

I know that you can solve this problem with a stored procedure or anonymous block.

We also face the same in oracle 9i version. we tried to re-org some tables for performance issue.But our tables have long and long raw datatype. then we approached the traditional way i.e 1. Export tables.2.Truncate tables.3.import tables.(use ignore=y).4.check the index validation.5.gather stats. Above was successfully done in our production environment.but some application downtime is required.

I've got a dblink between two Oracle databases. There are one view that I specify a join between four remote tables.
One of the tables does have a column defined as a long raw. I do not need that column; the query doesn´t make reference to it.However, when I specify the query, I get this error: ORA-00997; illegal use of LONG datatype.
"how can I accomplish this query, over a dblink, given that one table has a long raw that is not part of my query ?

I am working on a database application which works as a data access layer. The application uses OCI interface to connect and query to the Oracle Database. This application is certified on Oracle 9i and 10g client and works fine without any issue, but when I am certifying the application on Oracle 11g client, I am getting connection failed problem and following Oracle Error is displayed.
ORA-12533 illegal ADDRESS Parameter.
There is no change in the environment setting between Oracle 10g and Oracle 11g.
Following are the details of the environment
Version of Oracle 11g client is 11.1.0.6.0
Version of Oracle Database is 11.1.0.6.0.
Platform - Solaris 5.9 on sparc v9
On enabling client trace with support level also does not work. It shows TNS error TNS-12533 illegal ADDRESS Parameter.
what could be the possible reasons that the connection is failing with Oracle 11g client, while the same is working with Oracle 10g client. As I said there is no environmental difference when performing this test. The only change is ORACLE_HOME setting for the corresponding Oracle client version.

I tried to create a DB link that connects to SQL server.Right now I could connect the SQL server and able to test the connection by tnsping. When I tried to create a dblink, it failed and the message shows
CREATE PUBLIC DATABASE LINK "ODBC" CONNECT TO "user" IDENTIFIED BY "" using 'hsodbc'
ORA-01741: illegal zero-length identifier
The problem is that our sql server does not have any password while identified by is a required field.

I have configured a physical standby database.
I have set the physical standby database to open read mode for a short while.
according to [URL] in order to set db in for from open read-only to applying redo data
Quote:
To change the standby database from being open for read-only access to performing Redo Apply:
Terminate all active user sessions on the standby database. Restart Redo Apply. To start Redo Apply, issue the following statement:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> DISCONNECT FROM SESSION;
To enable real-time apply, include the USING CURRENT LOGFILE clause:
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE
2> USING CURRENT LOGFILE;
this is what happen
SYS@ngdr> alter database recover managed standby database disconnect session;
alter database recover managed standby database disconnect session

ERROR at line 1:
ORA-00274: illegal recovery option SESSION

okay since I encountered the illegal recovery options session, I decided to use alter database recover managed standby database using current logfile; now the session seems to be hanging forever.

Trying to delete duplicate rows from a table. The problem is, they aren't exactly duplicate rows. Let me explain.
I am migrating data from a Oracle 8.1.7 db to a 10.2.1 db. In the older db, this certain table does not have a PK/Unique Index, but in the new db there is a unique index. The fields that the index is unique on are:
SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE.
In the old db, when I run this query I get 1229 rows. With a count of 2 each.
select SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE, count(*)
from customer_id_equip_map
group by SUBSCR_NO, SUBSCR_NO_RESETS, EXTERNAL_ID, EXTERNAL_ID_TYPE, ACTIVE_DATE
having count(*)>1;
They are duplicates on those fields, but they are not totally duplicate rows because there is a field called is_current that has 0 in one row and has 1 in the other. What I need to do, is delete the 1229 rows with is_current=0.

To remove fragmentation which is the best method.
First one :
-----------------
1)Created a backup table from the Fragmented table (This table is a partitioned one).
2)Analyzed this table.
3)DROP the Fragmented table
4)Inserted the backuped up data from backup table to the Re-created table.
5)Analyze this table.
Second method
-------------------
1) Create a backup table newly, with PCTFREE =0
2) Inserted the data from Fragmented table ( This is a partitioned table) to backup table
3) Analyzed this table.
4) Truncate Fragmented table
4) Did Exchange partition of Fragmented table with Backup table.
The second method is not found to be removing the Fragmentation. Before the fragmentation was 28% after Second method the fragmentation is still the same. While the first method the fragmentation reduced to 16%.
Query used to find Fragmentation.
select table_name,
round((blocks*8),2) "table size kb",
round((num_rows*avg_row_len/1024),2) "actual data in table kb",
round((blocks*8),2)- round((num_rows*avg_row_len/1024),2) "wasted space kb",

TYPE CashRecord IS RECORD(client_id VARCHAR2(100),
account_letter VARCHAR2(100),
cash_amount VARCHAR2(100),
cash_amount_ccy VARCHAR2(100) );
TYPE CashRecordTable IS TABLE OF CashRecord INDEX BY VARCHAR2(100); -- Indexed by client_id~account_letter~ccy
So if I did something like this;
l_cash_records CashRecordTable;
-- say for example that l_cash_rec/l_cash_rec2 has been defined..
l_cash_records('some index') := l_cash_rec;
l_cash_records('some index 2') := l_cash_rec2;
l_cash_records.COUNT would give me 2
How can I somehow remove 'some index 2' so that l_cash_records.COUNT is 1 ?

This is a simple question, but I cannot seem to find a solution. Here's the basic query:
select distinct accountno, parcelno, streetno||' '|| predirection ||' '|| streetname||' '|| streettype||' '|| postdirection||' '|| unitname||', '|| propertycity
from tblacctpropertyaddress ....
What I want to do is add is this logic: If Predirection is null, then no space between streetno & streetname. Same for postdirection and unitname. (for example, if both postdirection and unitname are null, there are no spaces between streettype and the comma before propertycity)
Also, when unitname is not null, I want to add the string "Unit " prior to the returned value in unitname.

I have requirement to suppress the duplicate nodes on same level in hierarchy query.
Below given is the script for it.
CREATE TABLE NODE_LVL (PARENT_NODE VARCHAR2(100), CHILD_NODE VARCHAR2(100));
INSERT INTO NODE_LVL VALUES('TBL_APL','TBL_AFL');
INSERT INTO NODE_LVL VALUES('TBL_APP','TBL_ACS');
INSERT INTO NODE_LVL VALUES('TBL_ADD','TBL_ADW');
INSERT INTO NODE_LVL VALUES('TBL_ADP','TBL_ADV');
INSERT INTO NODE_LVL VALUES('TBL_AOP','TBL_AOV');
[code]......
Table 'TBL_APP' is having 2 parent nodes i.e 'TBL_AOV' and 'TBL_ADV'
SELECT * FROM node_lvl WHERE child_node = 'TBL_APP';
At level 5 there is duplicate nodes i.e 'TBL_APP' and 'TBL_ACS' as parent_node and child_node respectively.
SELECT PARENT_NODE, CHILD_NODE, LEVEL FROM NODE_LVL START WITH PARENT_NODE = 'TBL_ACF' CONNECT BY PRIOR CHILD_NODE = PARENT_NODE;
I want to suppress such duplicates. So I added DISTINCT
SELECT DISTINCT PARENT_NODE, CHILD_NODE, LEVEL FROM NODE_LVL START WITH PARENT_NODE = 'TBL_ACF' CONNECT BY PRIOR CHILD_NODE = PARENT_NODE;
BUT requirement is to maintain the same order (of hierarchy) as it was before adding DISTINCT.

I've a table in data warehouse production with data which is partitioned by RANGE, sub-partitioned by HASH.Later we realized that subpartitioned are not needed as volume is less.
I tried below approah in DEV DB:
1. create table ABC_BAK as select * from ABC;
2. dbms_metadata.get_ddl('TABLE','ABC')
3. Removed the subpartitions details from the output of step 2 and prepared the script of create table without subpartitions
4. Drop table ABC
5. Create table ABC from script step 3.
6. Insert into ABC select * from ABC_BAK
7. Drop table ABC_BAK

The other day, we had a query run amok in our 2-node production cluster. The 3 temp files for the temp tablespace were all still set to autoextend unlimited, something I forgot to change after a recent upgrade. I created 3 new temp files and tried to delete the huge temp files. I did this from sqlplus with this commad:
ALTER TABLESPACE PSTEMP DROP TEMPFILE '+DATA/isis/tempfile/pstemp.291.641298061';
The huge files are still in ASM storage. dba_temp_files reports that the status of them is AVAILABLE but they have no RELATIVE_FNO. Grid Control reports their status as OFFLINE and their size as 0. They are actually close to 20 GB each.
I tested the above alter statement in two test instances, also RACed with ASM storage and the temp files were successfully deleted, but they were much smaller in size. At this point, how do I delete the three 20GB files from ASM in our production instance? Why didn't they delete the first time?

I am trying to select a row on the screen and delete a individual row from the screen after hitting the delete button. Whenever i select the row it gets highlighted and also the alert box comes up asking if the record needs to be deleted. When I say yes I notice that the row does not get deleted. The code behind the delete button is as follows
(P.S the block is based of a table and commit_form works and changes are saved to db but not delete_record)
begin
--
Set_Item_Property('my_block.emp_no_copy',current_record_attribute,'va_delete_record');
