I've got situation where one of the procedure causing insert into table rows but some of them are not needed Temporary I need to disable this and exclude some type of data being inserted by changing procedure.
I wouldn't want to change the procedure is there a way to write a trigger that would not allow to insert a row into a table if condition is met? Something of a logic:
CREATE OR REPLACE TRIGGER avoid_insert BEFORE (AFTER?) INSERT if entity_id = 123 DO NOT DO THE INSERT (DO NOT DO ANYTHING)
CREATE TABLE A(EMP_ID NUMBER, EMP_NAME VARCHAR2(100)) CREATE TABLE B(EMP_ID NUMBER, EMP_ATT1 VARCHAR2(10), EMP_ATT2 VARCHAR2(10)) INSERT INTO A VALUES(1, 'ONE'); INSERT INTO A VALUES(2, 'TWO'); INSERT INTO A VALUES(3, 'THREE');
[Code]....
This query returns all the matching row of A and B
SELECT A.EMP_ID, A.EMP_NAME, B.EMP_ATT1, B.EMP_ATT2 FROM A INNER JOIN B ON A.EMP_ID=B.EMP_ID
The output for this shows:
EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2 1 ONE 1ATT1 1ATT2 2 TWO 2ATT1 2ATT2 2 TWO 2ATT1.1 2ATT2.1 3 THREE 3ATT1 3ATT2
The requirement is to avoid duplicate rows even if matched:
EMP_ID EMP_NAME EMP_ATT1 EMP_ATT2 1 ONE 1ATT1 1ATT2 2 TWO 2ATT1 2ATT2 3 THREE 3ATT1 3ATT2
CODE AMOUNT DESCRIPTION AAA 5 five dollars for pizza AAA 2 two dollars for tips AAA 1 one dollar for dogsitting BBB 6 six dollars for babysitting BBB 1 one dollar for tips
My goal is to list all records, "grouping" by code, with sum(amount), but the final display has to show all descriptions, one for row, avoiding to repeat the "CODE" column and "sum(AMOUNT)" column.The result should be like this:
CODE SUM(AMOUNT) DESCRIPTION AAA 8 five dollars for pizza two dollars for tips one dollar for dogsitting BBB 7 six dollars for babysitting one dollar for tips
That is, the "CODE" is displayed only the first row, with its sum of "amount".I think I have to use the analytics functions, but I was a little stuck.
Given two tables in a 1:N relationship, I want to retrieve, for each parent row, any child row which either satisfies some condition cond1 or, if no child rows matching cond1 exist, which satisfies another condition cond2.
I can easily write such a query using NOT EXISTS, but I am forced to repeat the condition cond1. This is inconvenient, as the repeated condition is quite long (involving other tables as well), and I would like to write it only once.
For example (using the HR schema included in Oracle 10g XE): I want to retrieve, for each department, all the "new" employees (hired after a certain date) or, if no "new" employees exist, the department manager.
We are on oracle 10.2.0.4 on Solaris 10 and have a perf. issue with a bind variable using query. The query is in java application. I want to test its performance when the query doesn't use bind variable and instead uses the passed value as literal. How can it be done?
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO ---------- ---------- --------- ---------- --------- ---------- ---------- ---------- 7839 KING PRESIDENT 17-NOV-81 5000 10
1 row selected.
But the statements will be taken as similar statements by oracle (due to :vn). Now I want oracle to take it as literal and the change for this has to be done in java code in my actual scenario which has a different query (but conceptually it uses bind variable and I want it to use passed value as literal). How can it be done?
Sysaux Tablespace is running low. WE SET AWR RETENTION TIME=60 DAYS. WE ARE NOT INTEREST TO EXTEND SYSAUX TABLESPACE SIZE. Usually we take AWR weekly once. Some times we did ADDM report and ASH.
CODEsql>select TABLESPACE_NAME, FILE_NAME, BYTES/(1024*1024), AUTOEXTENSIBLE, MAXBYTES/(1024*1024) from dba_data_files where tablespace_name = 'SYSAUX';
1. What's the best SOLUTION ? 2. Can i shrink sysaux tablespace ? 3. I think , The size for all occupants in sysaux tablespace is less than 200 MB => how to find actual content of sysaux tablespace ? 4. What could be the reason for growth? Is there any way to free the space from sysaux table space?
i have data about 3 gb but my files in e:oraclexeapporacleoradataXE has grown to 16 gb
1)my e: drive has less space ,pls tel how can i fee some space and give it back to OS
2)is there any other place where i can free up some space from oracle and give it back to OS.

I got the error ORA-01653: unable to extend table <OWNER.TABLE_NAME> by <BYTE> in tablespace <TABLESPACE> in my production database. But I could see 4GB of free space available in the tablespace. But this was resolved after increasing the Tablespace size by 1 more GB. So I wanted to know how I can I reclaim the 4GB space ?
While searching in internet I got few tips like there will be a fragmentation in the tablespace, the free space available in the tablespace may not be a continuous block. To avoid this we need to reorganize the tables using ALTER TABLE <TABLE_NAME> MOVE <TABLESPACE>; command.
But in my tablespace there are huge number of tables exists I cannot do reorganization of all the tables. So I need to know how to identify particularly what are the tables has more fragmentation? so that I can go for reorganizing those tables only.
My Database version in 9.2.0.7 Tablespaces are Locally Managed
explain the difference in numbers between the queries? I am acutally more concerned about the ETM_XML clob since the descrepancy appears to be bigger.
SELECT table_name, column_name, segment_name, a.bytes FROM dba_segments a JOIN dba_lobs b USING (owner, segment_name) WHERE b.table_name = 'ETM_RAW_XML';
I have a tablespace of size 512 GB. On the basis of tables and indexes created on it, the space consumed should be 319GB but when I am retrieving the free space size , I am getting only 124GB of free space. That means around 70GB of space is missing.

i'm trying to read a text file into an oracel table. I'm having issues with this statement FIELDS TERMINATED BY ' ' fields are separated by 2 spaces. How ever Oracle is not recognizing ' ' or " " as double space. It is treating as one space thus shifting all coulmns.
how to check the maximum space ever used for TEMP. I want to know it because I need to resize the TEMP and I want to know how small it can be. As I can see from a documentation hURL....max_size is max number of extens ever used in a segment
I could multiply max_size by extent_size and it would give me the max size of temp ever used
SQL> select segment_file, extent_size, max_size from v$sort_segment;
I need to monitor the Database daily, so i need to check whether the size of the DB is increasing @ a slow rate or rather than that. I need to do it in RAC & NON-RAC.
lv_ret := WEBUTIL_FILE_TRANSFER.AS_To_Client_with_progress(lv_clnt_file, lv_srvr_file, 'Download from Application Server in progress', 'Please wait');
to download a file to my H: drive.Here lv_ret is a boolean variable.The file is not downloaded to my H drive when there is no enough space.How to capture that error?
I am having an issue with the LOBs in our Database. Our production DB is about 71G right now - if i do export/import using the DataPump - I see the data volume becomes 40G. I am sure its because of the LOBs in my Database. Our application uses lots of LOB datatype and I think the space is not being released.
The challenge is I cant do a full export/import in my Production DB as its a 24/7 system and to do export/import I need min. 5 hrs - which my business will not permit. I can I claim the unused space here. I have used Segment Advisor - but it has only given me 6G of space gain.
Is there any script I can try to use to reclaim space in the database.
CODECREATE TABLESPACE my_ts DATAFILE 'C:\Oracle\oradata\db\my_ts.dbf' SIZE 5M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K; ALTER DATABASE DATAFILE 'C:\Oracle\oradata\db\my_ts.dbf' AUTOEXTEND ON;
Its was sucessfully created and my_ts.dbf file has 5MB
charging with data...
CODEcreate table big_table tablespace my_ts as select * from dba_objects; select * from big_table; begin for i in 1..10 loop insert into big_table select * from dba_objects; end loop; end;
Now the my_ts.dbf file has 90MB
Now I want drop this table: CODEdrop table big_table purge;
And my tablespace file still has 90MB.
I already tried to restart the database but doesn't works...
In the table the names are having diffrent spaces for one name only one space between the words,for another name two spaces between words,for other names three spaces between the words.
I want to update with single space how can we that.
I am giving the data as follows.
CREATE TABLE student(sname VARCHAR2(30));
INSERT INTO student VALUES('PRAKASH BABU'); INSERT INTO student VALUES('RAJESH KUMAR'); INSERT INTO student VALUES('POORNA CHANDAR'); INSERT INTO student VALUES('ANIL RAJ'); INSERT INTO student VALUES('ABHI RAM KONA'); INSERT INTO student VALUES('SRI TEJA MEDI');
Like this the table contains millions of rows.
I want to update the names like this.
PRAKASH BABU RAJESH KUMAR POORNA CHANDAR ANIL RAJ ABHI RAM KONA SRI TEJA MEDI
