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 have a requirement like getting list of values from one table and inserting them into another table.I have tried with sub querying but didn't worked out because the select query is returning multiple values.
how to proceed further and the ways how can I write this requirement.
I have some issues in passing array values to IN clause.
I am passing a String Array from Java to PL\SQL and want to use the Array values in the IN CLAUSE of Select Query
cust_array is the Array
search_id VARCHAR2(1000);
search_id := '';
FOR j IN 1 .. cust_array.count
LOOP
IF (j != 1) THEN
search_id := search_id || ''',''' || cust_array(j) || ''';
ELSE
search_id := search_id || '''' || cust_array(j) || '''';
END IF;
END LOOP;
trying to form a string of below form: search_id '3211335201','3211335209','3211335279','3211335509'
and use the string search_id in the IN clause of the search Query select * from DPP_EMP where empl in (search_id)
but the query does not returns any result
When I try to hardcode the values in the query as below, its returing 4 rows
select * from DPP_EMP where empl in ('3211335201','3211335209','3211335279','3211335509')
How to achieve this (String to the IN clause) or is there a better way of passing the Array values to the IN clause
I have this query
SELECT wmsys.wm_concat (gp.prog_acronym)
FROM inf_program gp, ea_audit_program ap
WHERE ap.sys_prog_id = gp.sys_prog_id
AND ap.sys_audit_id =484
is there any way I can check the datatype of the result of the above query ? ,my dba added some patch to oracle , after the patch this query is returning a clob in java , it should return string and it used to return string before patch and in other databases it returns string, I can check the return type only from java side , is there any way oracle can say me the datatype ?
Is there a technique to getting a Top-N query to work as a sub-select in a larger query -or- is there another way to generate Top-N like results that works as a sub-select?
Background:
We have a large query that is being used to build an export from a legacy HR system to a new one. Amount the data needed in the export is the employees primary phone number.
The legacy HR system allows multiple phone numbers to be stored in a simple table structure:
SELECT emp_id, phone_type, phone_number
FROM employee_phones
emp_idphone_typephone_number
------- --------------- -------------------
46021CELL2222222222
46021HOME1111111111
46021WORK3333333333
The new HR system does allow for multiple phone numbers, however they need a primary phone number identified and stored with the employee master information. (Subsequent phone numbers get stored in alternate table.)
From a business perspective, we have decided that if they have a HOME phone in the legacy system that should be the primary in the new system, if no HOME phone, then WORK, if no WORK then CELL.
That can be represented as:
SELECT *
FROM employee_people_phones
WHERE emp_id = '46021'
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')
emp_idphone_typephone_number
------- --------------- -------------------
46021HOME1111111111
46021WORK2222222222
46021CELL3333333333
Or similarly with Top N concept:
SELECT *
FROM (SELECT *
FROM employee_people_phones
WHERE emp_id = '46021'
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results
WHERE ROWNUM = 1
emp_idphone_typephone_number
------- --------------- -------------------
46021HOME1111111111
Or really what I want in my export:
SELECT phone_number
FROM (SELECT phone_number
FROM employee_people_phones
WHERE emp_id = '46021'
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results
WHERE ROWNUM = 1
phone_number
-------------------
1111111111
However, when the Top-N query is added as a sub-select in a larger query using the employee id from the larger query (WHERE emp_id = export.emp_id), it fails saying that �export.emp_id� is not a valid id.
(SELECT phone_number
FROM (SELECT phone_number
FROM employee_people_phones
WHERE emp_id = export.emp_id
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results
WHERE ROWNUM = 1)
1.Any way around this? Is it possible to put a Top-N (with a WHERE clause using data from the main query) in a sub-select?
2.Any alternatives (other than Top-N) to delivering a ROWNUM=1 result with a �custom� ORDER BY statement?
Other Notes: Yes, we know we could do two queries in the data conversion first deliver the bulk data to the target table, and then update with the phone numbers. However, for multiple reasons, that is less than desirable.
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,

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

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.

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?
