in my table there is a row as below.
CITY_ICITY_NST_PROV_CPSTL_CUPDT_USER_IUPDT_TSUPDT_PGM_I
342DC79a03654822-FEB-12 02.02.13.410000000 PMOMR
when i use below below query, there are no values returned.
select city_i from city_e where (trim(city_n))= 'DC' and st_prov_c=79 but while i use below query, im bale to get the result
select city_i from city_e where city_n='DC' and st_prov_c=79
I am looking to simplify the below query,
DELETE FROM A WHERE A1 IN (SELECT ID FROM B WHERE BID=0) OR A2 IN (SELECT ID FROM B WHERE BID=0)
Since both the inner queries are same,I want to extract out to a local variable and then use it.
Say,
Array var = SELECT ID FROM B WHERE BID=0;
And then ,
DELETE FROM A WHERE A1 IN (var) OR A2 IN (var)
How to do this using SQLPLUS?
I want to run below query to get the result set that I am after. But It takes long time even with the indexes...Here in IM_Mapping table is having 1.7 mio records and T_Extract table about 35000 records. All the other tables having below 1000 records
SELECT DISTINCT T_Extract.SerGrp, T_Extract.SerCat, T_Extract.Component, T_Extract.Mod_Item ID,
" ##" AS IM, IM_Mapping.TrfCode, IM_Mapping.CatCode, IM_Mapping.CatDescr, IM_Mapping.SubCatCode, IM_Mapping.SubCatDescr,
LKP_Item.Group, LKP_Item.Modality Source
FROM ((LKP_Product

T_Extract.Component
T_Extract.Mod_Item ID

Just want to know if there is any possibility of running the query with all the Groups in one go
Even if I run group wise it took 30 min query still running without any results...Is there anyway of restructuring the query for better performance.
My scenario is something like this:
MyTable
Rownum Colval
1 23
2 34
3 45
I need to write a query which will get me output: 233445, i.e. all the three rows concatenated. How can it be done? I want to do it through sql only and not to use PL/SQL. Is this possible?
I have a sql query which fetch the data from 4 different tables. I want to write the output of that query into a excel or a CSV file without using TOad and all. Let me know is it possible via creating function or procedure.

I saw some exemples of "pivot query" but I still looking for a solution.
when I am executing the below query getting diffrent count every time and not able to guess what is happening.
SELECT

I need a a query which will give the result of most expensive query i.e. which is taking most of I/O /memory.

Like this i need to generate 4 files and zip it then send mail with attachement of that zip file.
Can we automate in PLSQL? If it is possible pls share the script.

In the execution plan of STEP-3, against ID-1 the operation RESULT CACHE is shown which shows the result has been retrieved directly from Result cache. Does this mean that Oracle Server has Incrementally Retrieved the resultset?
Because, before the execution of STEP-2, the cache contained only 2 records. Then 1 record was inserted but after STEP-3, a total of 3 records was returned from cache. Does this mean that newly inserted row is retrieved from database and merged to the cached result of STEP-1?
If Oracle server has incrementally retrieved and merged newly inserted record, what mechanism is being used by the Oracle to do so?
I am unable to insert the result set of query into corresponding SQL Table type variable where as same functionality can be accomplished by PL/SQL table type variable. Can't we access the same by using SQL type variable?
Ex:
Step 1:
SQL Object type , Table type Objects creation :
drop type sql_emp_tab_type ;
drop type sql_emp_type ;
create or replace type sql_emp_type as object
(
empno number,
ename varchar2(20),
[code]...
Step 2: Accessing the table type object from PL/SQL block

SQL> declare
2
3 tab_type_var sql_emp_tab_type := sql_emp_tab_type();

5 begin
6
7 tab_type_var.extend(10);

Step 3: Instead of SQL Table type , if we define the corresponding PL/SQL table type variable
SQL> declare

I have a table MESSAGE which has some billion entries. The columns are msg_id, vehicle_id, timestamp, data, etc.I have another table VEHICLE which holds static vehicle data (about 20k rows) such as vehicle_id, licenceplate, etc.
My first target was to partition the table via timestamp (by range) and subpartition by vehicle_id (by hash).So I could easily drop old data by dropping old partitions and tablespaces.
Now comes the new difficult 2nd target: the messages of some vehicles must be kept forever.My idea is to add a column KEEP_DATA to the table MESSAGE. I could try to partition by timestamp AND KEEP_DATA, subpartion by vehicle_id.The problem of this idea is that i have to update billions of rows.
It would be perfect if there is a possibility to add this KEEP_DATA-flag to the table vehicle.Is there any way to "link" this information to a column in MESSAGE table?
I mean something like this:
alter table MESSAGE
add column (select keep_data from vehicle where VEHICLE.vehicle_id = MESSAGE.vehicle_id as keep_message) ;
Is there some possibility like that? Would the partitioning on this column / statement work?Would the value of the keep_message be calculated on runtime?
If so will the performance influence be noticeable?If so will the performance also sink if the application is querying all rows except the keep_message?
