PL/SQL :: Searching String In A Table
Sep 9, 2013I am using Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production.
I have a situation where I need to find the number of occurrences of a string that is present in a table having comma separated values. To explain with an example:
create table test_data ( textfield varchar2(100));
insert into test_data values('DM,HM');
insert into test_data values('EM');
insert into test_data values('AM,CA,CD,FM,ST');
insert into test_data values('LS');
insert into test_data values('TQ,SP,AM,FM,ST,CA,CD');
insert into test_data values('TQ,SP,AM,FM,ST,CA,CD,LS');
insert into test_data values('DM,HM,LS');
The data in the table test_data looks like DM,HMEMAM,CA,CD,FM,STLSTQ,SP,AM,FM,ST,CA,CDTQ,SP,AM,FM,ST,CA,CD,LSDM,HM,LS Now I need to search"LS" in the table test_data. Basically, I need to find if "LS" is present at least once in any of the rows or not. I want to avoid looping here.
PL/SQL :: Load Data From Index By Table To Table
Jun 27, 2013We need to load data from index by table to table.Below code is working fine.
declare
query varchar2(200);
Type l_emp is TABLE OF emp%rowtype INDEX BY Binary_Integer;
rec_1 l_emp;
begin
[Code]....
But data from source table and target table is dynamic.Ex:In above code, emp(source) and target table is emp_b are static. But for our scenario is depends on the source table , target would change as below.If source is emp then target is emp_bIf source is emp1 then target is emp_b1 ............
create or replace procedure p(source in varchar2, target in varchar2)
as
query varchar2(200);
source varchar2(200);
Type l_emp is TABLE OF emp%rowtype INDEX BY Binary_Integer;
rec_1 l_emp;
[Code]....
Its throwing. How to implement this scenario .

PL/SQL :: Index Range Scan And Table Access By Index Rowid Versus Table Access Full
Oct 5, 2013Let's consider such table that all rows fit into single block:
SQL> create table test as select rownum id, '$'||rownum name from dual connect by level <= 530;
Table created.
SQL> create index i_test on test(id);
Index created.
SQL>
SQL> begin
[code].....
why does approach with full scan take longer even if table occupies only one data block? PS. 11gR2
Performance Tuning :: Local Index Versus Global Index On Partitioned Table

Oct 18, 2011I need to check if a small collection contains a specific value. I know I can use the .exist method to let me know if the nth element exists. But is there a similar syntax for checking if an actual value exists?
So the below collection has 6 values (300,301,310,320,400,410) after the cursor values are fetched. I want to use something similar to the below exists syntax in order to search the collection for a value (rather than position) within an IF statement.
The below code shows the kind of thing I want to do. Currently, unless my test value (310) is in the range 1 to 6 the test will always return FALSE. But is there a similar syntax for testing against the value?
The example I have given is a simplification of what I need. In reality there will be more than one test value... returned by another cursor.
DECLARE
CURSOR c_type_id_usg
IS
[Code]....
-- get the list of sms type id usg values
OPEN c_type_id_usg;
FETCH c_type_id_usg bulk collect into l_type_ids;
CLOSE c_type_id_usg;
-- the above returns value 300,301,310,320,400,410
IF l_type_ids.exists(310)
then
dbms_output.put_line('I have found an entry ');
else
dbms_output.put_line('I have NOT found an entry ' );
end if;
END;

PL/SQL :: Searching Text Clobs From User_views?
Jul 22, 2013I needed to search for some specific text in the DDL of each of the views in a particular schema. The text column of the user_views is LONG, and I looked at some old Tom's threads for converting long2clob, but found these processes to be really cumbersome, so I just opted to use DBMS_METADATA.GET_DDL instead even if it is a little slow.
One area I do not have a lot of experience with is searching clob fields. I tried this but not sure what would be the appropriate function to use for something like this:
SELECT *
FROM
(
[Code]....
WHERE contains(object_text, 'WHERE t.policy NOT LIKE') > 0; -- Show the names of all views that contain the matching text
Tuning Searching Into Clob In Batch Operation?
Jul 3, 2012My application runs a batch procedure weekly once for searching 'A_Text' from a column in Table1 in a clob column in Table2 and inserts accordingly into another Table3.
code snippet is like this -
---
CURSOR cr_sn
IS
SELECT serial_number
[Code]....
TABLE1 will have at least 1.1 Million rows but not significantly more than this.
This procedure takes 24+ hours to complete. I tried -
1. putting parallel hint ( INSERT /*+ PARALLEL*/INTO Table3)
2. partitioning TABLE2 based on last_update_date and putting a where clause in the above query last_update_date ( last_update_date between date1 and date2)
Forms :: Creating Searching Tool Using Oracle 6i?
Nov 26, 2012I have created searching tool using oracle forms 6i. while searching the cursor move from text field (A) to other block query the data according to the field (A) and come back again to field (A). Everything is working fine but the problem is, when the cursor move back to the field (A) the existing text is highlighted and when user right something in it. It's overwriting the existing text.
I want when the cursor moving bank to the field (A) the text should not be highlighted and when the user writes something that will be added to the existing text.
SQL & PL/SQL :: Insert Using String Matches / Matching And Searching Match
Jul 3, 2012i have three tables ot_cut_head,ot_cut_det and om_mc_master based on which fourth table ot_cut_opr and fifth table ot_cut_mc must get populated , Conditions are as follows
first one is based on job_no in ot_cut_head the selection criteria will be filtered,if the job number is like '%M' then type MISC will be chosen ,if job number is '%G' then GRAT TYPE will be picked from om_mc_master (Machine Master) and operations and machines based on this will be filtered.
Second all the cd_ps_desc will be taken from ot_cut_det and will be compared with om_mc_master to get their corresponding operation codes and machine codes , there can be 2 operations or 1 operation.
Finally if the match is found record will be inserted into ot_cut_opr and ot_cut_mc ,based on the criterias and what i want is the search criteria to be more flexible and if there are 2 operations 2 rows will be inserted and if one opeation is defined in om_mc_master ,then only one record will be inserted.
We have to make sure that if based on operation number stage will be populated ,if its first operation then stage will be 1 and if its second operation the stage will be 2.like previous operation also depends on them , the second operation will have the previous operation as first operation and so on.
CREATE TABLE om_mc_master ( mc_type VARCHAR2(12),mc_prof VARCHAR2(30),mc_prep_cd1 VARCHAR2(30),mc_mach_cd1 VARCHAR2
(30),mc_prep_cd2 VARCHAR2(30),mc_mach_cd2 VARCHAR2(30));
INSERT INTO OM_MC_MASTER VALUES ('MISC','TEE SCH','IR','HO','RE','HO');
insert into om_mc_master values('MISC','Vertical Brace','R','HM','I','HO');
insert into om_mc_master values('MISC','Pipe','IR','HO',NULL,NULL);
INSERT INTO OM_MC_MASTER VALUES ('GRAT','PL','RE','HO',NULL,NULL);

Data Pump Index Creation
Aug 7, 2011I am running Oracle Database 10g Enterprise Edition Release 10.2.0.2.0 - 64bit Production on RHEL5. I am busy with data pump import, from the log I can see that my import is busy with the constraints.

Now I want to manually create indexes while the import is busy.
Will this be advisable to do or what would be the impact?
SQL & PL/SQL :: Use Of Table Index?
Feb 10, 2012Am pasting the sample code here, which i got from some site..
DECLARE
TYPE population_type IS TABLE OF NUMBER INDEX BY VARCHAR2(64);
country_population population_type;
continent_population population_type;
howmany NUMBER;
[code]...
Here we are fetching indexes (like Antartica/Australia) from these two statements continent_population.FIRST or continent_population.LAST. If there are three or more indexes in the same table, how to fetch all of them?
I have tried using this, but doesnt work because loop variables are by default integers:
for i in continent_population.FIRST .. continent_population.LAST loop
dbms_output.put_line('i:'||i);
end loop;
Data Distribution On Local Non-prefixed Index?

View 1 Replies View RelatedHow To Partition And Index The Table
Oct 24, 2011how to partition and index my table for a special problem.
The table:
CREATE TABLE TEST (
ID NUMBER PRIMARY KEY,
U_VALUE NUMBER NOT NULL, -- Ranges from 0 - 30.000.000
O_VALUE NUMBER NOT NULL, -- Ranges from U_VALUE - 30.000.000
CREATE_TS TIMESTAMP DEFAULT SYSTIMESTAMP NOT NULL,
UPDATE_TS TIMESTAMP NOT NULL,
ITEM_TYPE NUMBER NOT NULL --<< Only 4 different values >>
);
As you can see, U_VALUE is ALWAYS lower than O_VALUE.I need to have the CREATE_TS in either main- or subpartition do drop the partitions after some time so i don,t have to use DELETE statements. The table has 360 millions rows.
The application has only 8 query which will always use a WHERE clause like this:
SELECT * FROM TEST
WHERE U_VALUE <= :1 AND O_VALUE => :2 AND ITEM_TYPE = :3
1. Is there any good technique how to create a good index for the queries (application will execute 120 queries per second)?
2. how to partition this table?

SQL & PL/SQL :: NULL Index Table Key Value
Sep 26, 2010We are getting the below error on a piece of code that chas been functioning fine for over 4 years..
ORA-06502: PL/SQL: numeric or value error: NULL index table key value
ORA-06512: at "pd.pf33", line 148
The line it's pointing at is merely a FOR loop that opens a cursor (select query) and loops through the items.
FOR rec IN csr_cash
LOOP
END LOOP
This piece of code has been functioning fine for years.. and never got this kind of error on a for loop. Could it be something internal to Oracle/underlying memory issues?
