View 1 Replies View RelatedI have a requirement when I need to append and show the contents of a CLOB (rich text) column into the Open office report.
The use case is as below.
User(s) can enter the details into a CLOB column.
This data entered by each user need to be concatenated onto another CLOB column which will hold all the history of changes. Mainly i wanted to perform a concatenation of these two columns.
|
| User Entered | Stored |
| Data Stored in Clob Column 1| Data Stored in Clob Column 2 |
| v_clob_1 | v_clob_target |
-------------------------------------------------------------------------------
|"Text 1" and a image |"Text 1" and a image |
-------------------------------------------------------------------------------
Any method to achieve this case. I had tried the following method to achieve this. But no success.
v_merge clob;
v_clob_target clob;
v_clob_1 clob;
1)
DBMS_LOB.APPEND(v_merge, v_clob_target);
DBMS_LOB.APPEND(v_merge, v_clob_1);
2)
DBMS_LOB.APPEND(v_clob_target, v_clob_1);
3)
v_merge:= v_clob_target || ''|| v_clob_1;
v_clob_target := v_merge;
I have a query which returns nearly 20k rows, as per the requiremnet we need to append all these rows in specific format and insert into single clob column.in the below procedure test_clob.textt is clob field.

v_gov_total NUMBER (20, 2);
v_emp_total NUMBER (20, 2);
v_text_exp CLOB;
v_pageaccess VARCHAR2 (15);

I have one table with clob field. The data in this field will contain string having transaction record data. Now I want to read data from this clob filed and insert different record in other oracle table.
example ->
Data in clob field will be->

We have oracle 10 g and a table contains a clob field . The table size is getting increased day by day . We have decided to zip all the clob data inside the table except last 1 month records.
Table : GENERIC_MESSAGE
Column:
message_id(number)
received_date(date)
message_xml(clob)
How we can do that keeping in mind this is huge data is present in table and huge transaction happened (10k transaction/hr)?
I am more of a C/C++ guy and relatively amateur in oracle. I have to update a table field from "Long" to "CLOB". I have planned to do a simple alter table, and as far as I know there won't be any issues.
Queries:
1. Although I have triple checked, is there any scenario under which there can be any data loss during the data type change? The data is very critical and no data loss can be entertained.
2. Is there any easy way to update all the related views without having to do so manually?
3. Any particular precautions I should take before introducing the change?
I want to extract the data from the Clob field. I have the following table,create table test123(col1 char(24), col2 clob); And following data,
Insert into test123 (col1,col2) values ('ABCDE','<?xml version="1.0" encoding="UTF-8"?>
<Attributes>
<Attribute DataType="Text-40" DisplayName="DropDirectory"
IsNotDeletable="Y" Modifiable="Y" Name="DropDirectory" Value="${Dir1}"/>
<Attribute DataType="Text-40" DisplayName="PrinterAlias"
IsNotDeletable="Y" Modifiable="Y" Name="PrinterAlias" Value="\Printer3Printer4"/>

<Attribute DataType="Count" DisplayName="PrintServerPort"
IsNotDeletable="Y" Modifiable="Y" Name="PrintServerPort" Value="2723"/>
</Attributes>');

The data will be available like this only, The same XML tag is used everywhere.

Is theree any way to generate the insert script (with the data) for an existing table.
In Toad, we can generate the DDL for a particular table. Just curious if it can be done using any Tool.

Perhaps this is a common request : I have 2 tables:
Table A
-------
ID Value
1 a
2 b
3 c
Table B
-------
ID AnotherValue
1 x
2 y
I am hoping to append a column from Table B to Table A based on a simple sql join (e.g:
Table A
ID Value AnotherValue
1 a x
2 b y
3 c (null)
)
I would rather stay away from the standard update statement since it takes far to long and I'd prefer not to use create table as I don't want to duplicate any data...is this possible to do ? (e.g: just insert the columns into this table ?) - or if it's possible the performance overhead just wouldn't make it worth it ?

Is there a way to apply changes to a data field on oracle forms for specific users?
For example, I have an oracle form that applies the below masking code for a certain field called CUSTOMER_ID
IF :SYSTEM.BLOCK_STATUS = 'QUERY' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
ELSE
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_FALSE);
END IF;
But I only want this masking to be applicable to CERTAIN users. For example, the psuedo code would be like
IF :SYSTEM.BLOCK_STATUS = 'QUERY' and USERS_LIST = 'SUPERVISORS' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
Note that this users_list is a group of oracle database users, so I am a member of this group. Also note that this form is applied via the web via the application server.
Recently i created a form which contains emp_name,deptno,supervisor_name.For emp_name if i type the emp name (eg:allen) it will show me a list of employees named allen as a select list.For that i used a jquery script on page header
<link rel="stylesheet" href="URL.....
<script type="text/javascript" src="URL....
<script type="text/javascript">
[code]....
and i have created a dynamic action for emp name to fetch the deptno,supervisor_name if select the employee name it is working fine is if i type a emp_name which doesn't exist in the employee table it will show me a alert message employee does not exist and it will clears all the fields.
I have uploaded some tables from MS Access to Oracle and in the process, some Number fields have been converted to Text. This means that any Queries where there are calculations with those fields (which have been converted to text) don't work properly anymore.
I would like to change the field type from text to number (with cmd and sqlplus) as that's the only way I can access the oracle backend.
I am not sure what commands to use to change this.
Also, if I change the data type from text to number, is it likely I will lose some data?
And how do I backup the table before I do this?
I have few tables in Oracle 9i/10g , and they already have data in them. I am trying to migrate the data coming from various source systems into these Oracle tables. There is a chance that after loading I might get some unwanted data into these tables.
How do I remove just that data which I have loaded recently, and do not disturb the original data it already has.
Need to backup those tables and reload the data back if there is any problem, but I am looking at a different approach. I just don't want to change the existing system, as lot of users use the system.
I have the following four tables with the following structures Table A
ColA1 ColA2 ColA3 ColA4 ColA5 AA 100 CC DD EE
Table B
ColB1 ColB2 ColB3 ColB4 ColB5 AA 100 40452 A9 CDE
when these two tables were joined like the following:
Select colA1,ColA2, ColA3, ColA4, ColB3,ColB4, ColB5 from table A Left outer join (select ColB3, ColB4, ColB5 from table B where colB3 = (select max(colB3) from table B ) on (colA1 = colB1 and ColA2 = col B2)
Now i have to join the next table C with table B
Table C structure is
ColD1 ColD2 ColD3 Desc1 A9 Executive Desc1 A7 Engineer
I have the common column such as ColD2 and colB4 to get the Col D3
how do i join the existing query + join between table b and table c?
I need to search a pattern backwards in a CLOB field.Function DBMS_LOB.instr does not work with '-1' offset (where to start the search) as instr does.
Parameters: instr(text_to_be_searched, pattern, offset, nth)
Example: I want to search 'Hello world' for the first instance of the letter 'o' starting from the end, backwards.As you can see, result for DBMS_LOB.instr is null when entered -1 for offset.
select
DBMS_LOB.instr('Hello world','o',-1,1) lob_i,
instr('Hello world','o',-1,1) std_i

I have a table in schema with a BLOB field. I store employee's picture in this field. Fields in this table are emp_id (number) emp_name (varchar2) and emp_photo (BLOB). I want to ask if there is a way in pl / sql that i could empty this BLOB field to null or reset this field so that user can change the saved photo graph and save another one.
what i am looking for is something like
alter table employee set emp_photo = empty_blob() or alter table employee set emp_photo = null
