Oracle- Parsing data in a specific row into a temp table

Dug — Tue, 21 Jul 2009 15:44:43 +0000

I have used
select text from dba_views
where owner = ‘Something’
and view_name = ‘Something’;

I get back a row with the word (MEMO) in it. However that row contains a lot of text when clicked on. Such as something like

SELECT
/*
SCCS Rev 1.1
10/14/2002 by Blah

SCCS Rev 1.2
10/24/2002 Blah

SCCS Rev 1.3
11/08/2002 D.Dolganenko
1. Time scan

How can i parse each row of that text, into a temp table?

Oracle- Source Code for Tables and Views cannot find

Dug — Tue, 21 Jul 2009 13:38:53 +0000

Hey, I am working on some coding to find a certain phrase with a number like (SCCS Rev 1.13) in the comments within procedures, tables, views, packages, etc. It works for everything except Tables and Views. This is because i am using Dba_source which does not include the source code for table or views. Does anyone have any ideas of what i cud do or what i could use to search for the phrasse in those too? I included my code below. The first procedure uses the data within a table (Project, Owner, Name) passed from the second procedure below.

CREATE OR REPLACE package body REINARD_DEV5.RevNum_pkg
as
procedure UPDATE_REVNUM(Object_project in varchar2,Object_owner in varchar2,
Object_name in varchar2) /*Procedure updates RevNum in Column*/
is
Cursor RevNum_cur is
select Text from dba_source
where owner=Object_owner
and name=Object_name
and TRIM(upper(text)) like upper(‘SCCS Rev%’);

NumB_old number:=0;
NumS_old number:=0;
NumB_new number;
NumS_new number;
Begin
For RevNum_rec in RevNum_cur
Loop
RevNum_rec.text:=REPLACE(REPLACE(TRIM(LTRIM(LTRIM(TRIM(RevNum_rec.text),’SCCS Rev’),’rev’)), CHR(10) ), CHR(13) ); /* Filters out text SCCS Rev */
NumB_new := To_number(Substr(RevNum_rec.text,0,instr(RevNum_rec.text,’.')-1));
Begin
NumS_new := To_number(Substr(RevNum_rec.text,instr(RevNum_rec.text,’.')+1));
Exception
when others then
NumS_new := To_number(Substr(RevNum_rec.text,instr(RevNum_rec.text,’.')+1,2));
End;
If NumB_new >= NumB_old then
If NumS_new >= NumS_old then
NumB_old := NumB_new;
NumS_old := NumS_new;
End if;
End if;
End loop;
If NumB_old =0 and NumS_old = 0 then
Update Reinard_dev5.Test
Set Revision = ‘ ‘
where Table_owner = Object_owner
and Table_name = Object_name;
else
Update Reinard_dev5.Test
Set Revision = To_char(NumB_new)||’.'||To_char(NumS_new)
where Table_owner = Object_owner
and Table_name = Object_name;
End if;
Exception
When others then
Update Test
Set Revision = ‘Error’
where Table_owner = Object_owner
and Table_name = Object_name;
End;

procedure Find_RevNum /* Selects all rows in table and inserts into update procedure */
is
Cursor RevNum_cur is
select *
from Test;
Begin
For RevNum_rec in RevNum_cur
Loop
Update_RevNum(REVNUM_REC.PROJECT,REVNUM_REC.TABLE_OWNER,
REVNUM_REC.TABLE_NAME);
End loop;
End Find_RevNum;

Variation in space occupied in same TABLSPACE by equally populated tables.

DBDEV — Mon, 13 Apr 2009 12:41:12 +0000

I am inserting data in table T2 from T1(INSERT INTO T2..SELECT..FROM T1..). Both tables are in same tablespace. Even though records in T2 are less than T1,size occupied by T2(12 GB) is much higher than T1(440 MB). WHat may be the reason(s)?

How Do I release unused space from a tablespace after dropping a blob table

Hmhora — Thu, 05 Feb 2009 17:11:30 +0000

I have a 30 GB BLOB table in a 162 GB tablespace. After I used the online table reorg to move this BLOB table and its BLOB index to another tablespace, Toad tells me that I have about 35 GB free. However, I can not reduce the size of this tablespace (i.e, resize the datafiles associated with this tablespace).

Question: Is there a way to reduce the size of a tablespace after we drop a big table in that tablespace ?
