I am trying to execute dynamic SQL in Stored Function and I don't know how to do this.
Explanation:
In the function I am calling pr_createtab is procedure which will create a physical table and return the table name in the out variable v_tbl_nm.
I need to query on this dynamic table and return the result as return result. But i am not able to do it.
Here T_web_loylty_report_table is a type.
CREATE OR REPLACE function CDW_DSS.f_ReturnTable(i_mrkt_id in number, i_cmpgn_year in number)
return T_web_loylty_report_table is
v_tbl_nm varchar2(50);
i_cntry_cd varchar2(20);
v_sql_str varchar2(32567);
[code]......

We have a table in the client database that has two columns - column parent and column child. The whole hierarchy of DB table dependencies is held in this table.If Report 1 is dependent on Table A and Table A in turn is dependent on two tables Table M and Table N. Table N is dependent on table Z it will appear in the db table as,
Hierarchy Table
Parent Child
Report1Table A
Table ATable M
Table ATable N
Table NTable Z
Requirement :
From the above structure, we need to build a table which will hold the complete hierarchy by breaking it into multiple columns.The o/p should look like this
-ParentChild 1Child 2 Child 3
-Report1Table ATable M
-Report1Table ATable N Table Z
Child 1, Child 2, Child 3 ....and so on are columns.The number of tables and the no of hierarchical relationships are dynamic.
SQL Statements to create hierarchy table:
create table hierarchy (parent varchar2(20), child varchar2(20));
insert into hierarchy values ('Report1','Table A');
insert into hierarchy values ('Report1','Table B');
insert into hierarchy values ('Table A','Table M');
insert into hierarchy values ('Table B','Table N');
insert into hierarchy values ('Report2','Table P');
insert into hierarchy values ('Table M','Table X');
insert into hierarchy values ('Table N','Table Y');
insert into hierarchy values ('Report X','Table Z');
Approached already tried :
1) Using indentation : select lpad(' ',20*(level-1)) || to_char(child) P from hierarchy connect_by start with parent='Report1' connect by prior child=parent;
2)Using connect by path function :
select *
from (select parent,child,level,connect_by_isleaf as leaf, sys_connect_by_path(child,'/') as path
from hierarchy start with parent='Report1'
connect by prior child =parent) a where Leaf not in (0);
Both the approaches give the information but the hierarchy data appears in a single column.Ideally we would like data at each level to appear in a different column.

I have to create a table which contain history of a main table. like this:
if the main table is
========================
nametypelengthnot null
Avarchar5Y
Bvarchar5N
Cvarchar5N
Dvarchar5N
========================
[code]....
I've plan to so this by create a trigger in main_table. my problem is my main table have a lot of fields and I can't write a code to control it 1 by 1 like :
if old.A <> new.a
insert into history("A",old.A,new.a)
if old.B <> new.B
insert into history("B",old.b,new.b)
......
I decided to select column name from the data dictonary using this SQL:
SELECT column_name FROM user_tab_columns WHERE table_name = '<<Table Name>>';
and then do a loop over the resultset and use the column name I've got , like this (its just an idea, may be not a write syntax):
BEGIN
.....
FOR i IN 1..:result.COUNT LOOP
if ld.colname[i] <> :new.colname[i]
INSERT INTO history
VALUES ( colname[i], ld.colname[i], :new.colname[i]);
END LOOP;
END;
but I can't write a "old.colname". I try with " old.'colname' ", " ld.'colname' " but it won't work.how to create a history file like I've describe.

I want to create a new table 'b' from table 'a'.I know the query will be " create table b as select * from a;" But there is some twist in my question. I do not know how many table are there in table 'a' all I know is that there is one column named "timestamp" in table 'a'.
Now I want to create table 'b' with the difference that the column "timestamp" should contain the value "sysdate" instead of the earlier values which were there in table 'a';
Note: I have to do this in single query. I can not first create table 'b' from 'a' and then update the values of column "timestamp" to sysdate.

If I try create table from the following syntax
create table a as select * from table b;
Then I could get only base table structure alone, I would like to get partition syntax as well.

I am trying to create a table that will increment my ID by one using the following commands:
/*Creates the log needed to increment ID*/
create sequence seq_log;
CREATE TABLE MESSAGE_LOG_TABLE
(
IDNUMBER(10)NOT NULLPRIMARY KEY,
[code]...
When I run the above my create sequence completes successfully but I get a ORA-00955: name is already used by an existing object error message on the create table. I have dropped all tables and sequences before running my command but I still get the same error message.
After it bombs out it appears that SQL+ want's more information for it begins to give me line numbers as if it is looking for a ";" to end the above command. I have to exit SQL+ and log back in to continue working.

running on 10.2.0.5 and above satisfies the following:
having locally managed tablespace with assm enabled
create table t1 (n1 number) storage (next 1M);
insert into t1 values (1); commit;
create table t2 storage (next 2M) as select * from t1;
This will indeed set the storage option next to 2M;
The same situation in 10.2.0.4 will allways set next option for the ctas statement to the initial value of table t1.
Is this an impact of patch set 4 (10.2.0.5)? Why does it differ from 10.2.0.4 to newer releases?

creating a temporary table.i have this query mentioned below
CREATE TABLE WEBPEN AS (SELECT PNSR_PPO_NO PPO,PNSR_FILE_NO,
DECODE(F_GET_APPLN_NO(PNSR_PK),'1',PNSR_VOL_NO,F_GET_APPLN_NO(PNSR_PK)) APPLN_NO,
PNSR_FULL_NAME NAME,
TO_CHAR(PNSR_DOB,'DD/MM/YYYY') DOB,
TO_CHAR(PNSR_DOR,'DD/MM/YYYY') DOR,
F_GET_ADBK_NAME(PNSR_TO_PENSION) TREASURY,
PNSR_SPOUSE_NAME SPOUSE,
[code]....
This creates a table webpen with around 54107 rows. What i am want is every time run "select * from webpen" it should run the above query and give the result as per the values in main table M_PENSIONER ,M_PEN_DCRG_WITHHELD.
What i want is it should truncate the existing values and insert the value by running the above mentioned query .

Today I’m trying to make a “table” from a column. The information I’m using looks like:
AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ - K
I need my table have these columns:
Column1 Column2 Column3
AAA B CCC
DDD E FFF
GGG H III
JJJ K
So I began to divide the string into smaller pieces:
SELECT LEVEL reg,
REGEXP_SUBSTR('AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ-K','[^|]+', 1, LEVEL) ferroc
FROM DUAL
CONNECT BY LEVEL <= LENGTH('AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ-K') - LENGTH(REPLACE('AAA-B-CCC|DDD-E-FFF|GGG-H-III|JJJ–K','|')) + 1; What I get is:
>
REG ferroc
1 AAA-B-CCC
2 DDD-E-FFF
3 GGG-H-III
4 JJJ - K
>
After this step I’m lost, I try to do almost the same thing than in the first query but mi information get mixed.

My requirement is to

This has to be done parallel for all the tables for which this flag is enabled and by that trigger delete all those rows which were backed up as table.

In a pl/sql procedure code, I created a normal table (create table) using dynamic sql. Then I used that table in procedure for further processing. But while compiling, it gave error that table does not exist. I can understand that he table is not present in DB, so the error came. But at the same time I need to create a table dynamically, use it and drop it. Does it mean that I need to make every query referencing that table as dynamic ??

My developer came with a requirement of creating partitions on a table which has 40 million records. His exact requirement is to create as many as partitions in such a way that 1 partition should not exceed 5k-10k records and these records should be inserted/updated on the same date (i.e. using a column as source_timestamp field). How to accomplish this?

I wonder how I can limit the queries in a table? This limitation would be that from a certain time, it allows queries. Before the opening hours, permitting no select.
Example: Allow SELECTs in table only after 16 p.m.

I have a table with over 100000 records.
The format and data is something like this:
Region Code,Name,Surname,ID_Number
1,John,Doe,67
1,Sarah,Jason,45
2,Bob,Marley,69
3,Steven,Johnson,900
2,Harry,Potter,890
3,Sandy,Bay,567
3,Else,Taylor,789 .....
I have about over 100 region codes and each region would like to get their own data. I can manually do the extraction and create a new table for every region, but it's going to take too long.

I'm having some trouble dealing with the PL/SQL coding. At the moment, I have a file (set of data) that is read using java. An array is created (line by line) and is passed into a temp. table, which is then called by the plsql (call PKG_xxx.PRC_xxx...) script/command for processing. Is there any way I could directly get the file loaded into plsql (into a temp. table maybe?)
The data are just numbers and letters. I already got the PL/SQL part to select the set I want for different cases. All I need is to get the file (directly or indirectly) for the procedure without going through java.

difference between the ways we create Reverse Key Index on the table.The two ways are as below:
1) CREATE INDEX <Index_Name> ON <Table_Name>(<Column_Name) REVERSE ;
2) CREATE INDEX <Index_Name> ON<Table_Name>(REVERSE(<Column_Name>)) ;
Which one is the appropraite one.
Are both going to act in the same way.
I created index in both ways one by one on the table.But when I fire the select statement against the same table, The explain plan doesn't show any cost and it shows the full table scan in both ways.The select statement used is as below...I want to compare the column with string RBO(i.e('RBO%') at the start.
SELECT *
FROM <Table_Name>
WHERE REVERSE (<Column_Name>) LIKE '%OBR' ;
The select statement is giving me the correct result. Only the explain plan is showing Full Table Scan.can we use this reverse with IN operator also in the same way by reversing the values.
