How To Give Table Name Dynamically In A Select Query
Aug 23, 2012
I have 12 different tables
Record_jan
Record_feb
.
.
.
Record_nov
Record_dec
Based on the month i need to do some i/o operations from these table.
For eg: If it is january then Record_jan table should be accesed or for nov Record_nov table should be accesed.
If I try to store the table name in some variable and then give the variable name in place of table name then it gives error.
var:=Record_month;
Select * from var;
this gives error.

I have a problem executing a function.
There are two tables,
1. Table with column names of a second table mapped to certain variables.
ex: Table1
col1, var1
col2, var2
col3, var3
--------
--------
2. Table with the values for columns as given in table 1 ex:
col1, col2, col3, col4, col5,
a , aa , 1 , x1 , p
b , ab , 2 , x2 , q
c , ac , 3 , x3 , r
I have to select values from table2.col1 do some processing and calculate values and store it in a table then do the same thing with col2 and so. This needs to be done for all the columns that appear in table1.For example in table 1 i have only three columns mentioned thus i have to process col1, col2 and col3 from table2. col4 and col5 will not be processed since they do not appear in the first table.
The problem is i have hundred columns in table 2 and the user can add up to hundred columns in table 1 as and when it is required.
I have created a cursor to first select column name from table 1 where variable is not null.For each value in cursor i put it in a local variable.
Second step is to select values from table2 where instead of column name i am using the local variable.But the problem is instead of choosing values from col1 the query returns the value as col1 (the value of local variable)

I have a table A on dev with definition as TAble A(address,name) and the same table on Prod is defined as Table A(name,address).
my question is Ihave one package in that am trying to insert into this table as follows:
INSERT INTO A
SELECT b.name name,
a.address address,
[Code]....
so the query works on Prod but fails on Dev because column order is different.
I have 2 solutions:
1. I can mention column names in insert line and modify the query but tomorro some body changes again the definition of table A I need to change the query, so do I have solution in oracle sql that can handle the column order without specifying the column names in insert line.
so tomorrow On prod column order and on Dev column order is different though my sql should successfully execute.

We are trying insert records from a select query into temporary table, some of the records is missing in the temporary table. The select statement is having multiple joins and union all which it little complex query. In simple terms the script contains 2 part 1st Part Insert in to temporary table 2nd part Select query with multiple joins, inline sub queries, unions and group by classes and conditions Eg. If we execute select statement alone it returns some count for example => 60000 After inserting into the temp table, in temp table the count is around 42000 why is the difference?
It is simple bulk inserts... insert in to temp table select * from xxx. also, there is no commit in between. The problem is all the records populated by the select statement are not inserted in to temp table. some records are not inserted.
Also, we had some other observation. It only happens in its 2nd execution and not its first run. Hope there might be some cache problem Even, we also did not believe that. We are wondering. In TOAD, we tested however at times it happens. In application jar file, after "insert in to temp select * from xxx" we take the i. record count of temp table and ii. record count of "select * from xxx" separately but both doesn't match. Match only at 1st time.

I have a table that contains a CLOB column with pseudo-XML in it. I want to keep this data in an XMLType column so that I can leverage some of Oracle's built-in XML features to parse it more easily.
The source table is defined as: CREATE TABLE "TSS_SRM_CBEBRE_LOGS_V" ( "INCIDENT_ID" NUMBER, "EVENT_TYPE" VARCHAR2(100 BYTE) NOT NULL ENABLE, "EVENT_KEY" VARCHAR2(100 BYTE), "CREATION_DATE" TIMESTAMP (6) NOT NULL ENABLE, "CREATED_BY" VARCHAR2(100 BYTE) NOT NULL ENABLE, "LOG_MSG" CLOB);
The target (for testing this problem) table is defined as: CREATE TABLE "TESTME" ( "LOG_MSG" "XMLTYPE") My query is: insert /*+ APPEND */ into testme ("LOG_MSG")select XMLTYPE.createXML("LOG_MSG") as LOG_MSG from "TSS_SRM_CBEBRE_LOGS_V" b; In SQL*Developer, my error is: Error report:SQL Error: No more data to read from socket In SQL*PLUS and Toad, my error is: ORA-03113: end-of-file on communication channelProcess ID: 13903Session ID: 414 Serial number: 32739

How do you specify the value in START WITH dynamically during runtime. For example consider the bewlo scenario:
CREATE TABLE ISCT
(
ITEM_NO VARCHAR2(15 CHAR) NOT NULL,
ITEM_TYPE VARCHAR2(3 CHAR) NOT NULL,
ITEM_TYPE_SCO VARCHAR2(3 CHAR) NOT NULL,
[Code].....
Now if you create a view:
create or replace view test_v
(ITEM_NO, ITEM_TYPE, ITEM_NO_SCO,ITEM_TYPE_SCO)
as
SELECT T.ITEM_NO, T.ITEM_TYPE, CONNECT_BY_ROOT T.ITEM_NO_SCO,T.ITEM_TYPE_SCO
FROM
[Code] .......
Then run the below query:
select * from test_v where item_no_sco = '00245905'
--
the output is got within a second. but the real scenario is that both table icont and isct have millions of rows. In that case even this small query of the view takes 10minutes as there a FULL TABLE JOIN.
How do I give the START WITH in the view to make it faster i.e. even with millions of rows the output of this comes in seconds:
SELECT T.ITEM_NO, T.ITEM_TYPE, CONNECT_BY_ROOT T.ITEM_NO_SCO,T.ITEM_TYPE_SCO
FROM
(
SELECT NVL(C.ITEM_NO_CHILD, I.ITEM_NO) ITEM_NO, NVL(C.ITEM_TYPE_CHILD,
I.ITEM_TYPE) ITEM_TYPE, I.ITEM_TYPE_SCO, I.ITEM_NO_SCO
[Code] .......
MC: Remove code tags on INSERT, CM take care to not exceed 80 characters when you add coce tags: reformat yourself or do not do it.

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 ??

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?

Is there any way to generate columns dynamically by depending on the rows in a table in 11G .
Ex: If the deptno in DEPT table is not constant,then how to generate the N numbers of columns based on the deptno. Below query is working when we hard coded the deptno (10,20,30,40).What else if we more number of departments and we don't know the departments also.
Connected to Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Connected as dbo
SQL> SELECT *
FROM (SELECT deptno, job, sum(sal) sal
FROM SCOTT.emp GROUP BY job, deptno) PIVOT(sum(sal) FOR deptno IN(10,
20,
30,
40));

Firstly the table structures :
Create table cd_patient (pat_mrn varchar2(100)) ;
Create table cd_encount (pat_mrn varchar2(100), encounter_id varchar2(1000));
I need to write a code which dynamically reads the table name from user_tables (starting with cd) & load the data from remote database which has the same table name & structure based on the load number..
Static PLSQL statement would be :
declare
BEGIN
INSERT INTO "cd_patient" C-- DYNAMICALLY GET THE TABLE NAME
SELECT C1.PAT_MRN -- DYNAMICALLY GET THE COLUMN NAME
FROM REMOTE_DB.CD_PATIENT@XXX C1
WHERE C1.LOAD_NUMBER > 2;

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.
