I need to query an users name, manager,location and the manager's manager. Say the info for user A would be,
User : A
Location : Bangalore
Manager : B
Manager's Manager : C
I can get this in two step process.
select attribut,attribute_val from test_join where user_name = 'A';
select attribute_val from test_join where user_name =
(select attribute_val from test_join where user_name = 'A' and ATTRIBUT = 'manager') and
ATTRIBUT = 'manager';
But is there a way to get this in one single query ?
select * from test_1 IDNameTotal ----------- 1A100 2B100 3C100 4D100
test_2 table contains the concatination of ID's with comma seperated. Actually in this table ID column is of datatype varchar2. select * from test_2 ID ---- 1,2,3
My requirement is to select the data from test_1 table where the id values in this table exists in test_2 table. I tried with the belowselect statement, but could not get any data.
SELECT * FROM test_1 WHERE to_char(id) IN (SELECT id FROM test_2)
create table test_1 (id number, name varchar2(100), total number) create table test_2(id varchar2(100)) insert into test_1 values (1,'A',100) insert into test_1 values (2,'B',100) insert into test_1 values (3,'C',100) insert into test_1 values (4,'D',100)
I do not know the table name but have a query that for sure returns the table name and I want to select a column value from the table into my PLSQL variable.
If there are 100 colums or above in a table and we dont want select a single(any one) column from those 100 columns. is there any command or function to do this in oracle.
I can do it by writting names of all 99 columns but as this method is lenghty, so need some efficient way to do this.
like in SQL server we have a "except" keyword through which we can rule out the columns .
ex: select * except (column_name1,column_name_2) from Table_name.
if you grant select on a table to a user then u revoke select on this table that user still can desc this table, is this ok? what if i don't want that user to desc it?
I am dealing with a table containing millions of records. I have table loans_list table and he data looks similar to this..
LOAN_IDSEQUENCE_NUMCOMPLETE_DATE 1237000 1237005 1237010 5237010 6/23/2010 10:07:02 AM 5237000 6/23/2010 10:07:02 AM 12237000
I am trying to select only those loan_id from this table which contain all these 3 sequence_num = 7000,7005,7010 and containing null compelete date. I tried different way to write the query but can't think of efficient way of writing this query yet.
Since this table contain million of records, i dont prefer to call this table more than once in a query. I am just trying to avoid the longer time delay for the execution of this query..
I have a table with multiple column. A column named address have value of multiple lines. Now i want to select the address only of the first line. How does it possible.
CODECREATE OR REPLACE TYPE ADDR_T AS OBJECT ( ADDR1 VARCHAR2 (50), ADDR2 VARCHAR2 (50) ); CREATE OR REPLACE TYPE t_ADDr AS TABLE OF ADDR_T;

I have added some records and created index on ID column. I want to get result of CODEselect id, p.addr1,p.addr2 from nested_table n,table(n.COL1) p where id=1
Explain plan for that is:
CODESELECT STATEMENT ALL_ROWSCost: 8 Bytes: 231 Cardinality: 3 4 HASH JOIN Cost: 8 Bytes: 231 Cardinality: 3 2 TABLE ACCESS BY INDEX ROWID TABLE SYS.NESTED_TABLE Cost: 2 Bytes: 13 Cardinality: 1 1 INDEX RANGE SCAN INDEX SYS.FDSFAS Cost: 1 Cardinality: 1 3 TABLE ACCESS FULL TABLE (NESTED) SYS.COL1_TAB Cost: 5 Bytes: 163,840 Cardinality: 2,560
How to avoid full table scan on nested table? Cardinality is sum of all records in nested column in all rows in main table, why?
There are two tables like I posted below.I want a SQL query which selects all the rows from TABLE A which are not present in TABLE B. Also the select statement should pick all those rows which has updated value of COL_A2 in TABLE A.
TABLE A COL_A1COL_A2
AAAMOBILE BBBTABLET CCCDESKTOP DDDUNKNOWN
TABLE B COL_B1COL_B2
AAAMOBILE BBBUNKNOWN CCCDESKTOP
The select statement should return following rows from TABLE A
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.
CREATE TABLE test_A(member_id NUMBER(2) PRIMARY KEY, MEMBER_name VARCHAR2(20), MEMBER_parent NUMBER(2) DEFAULT NULL); INSERT ALL INTO test_A VALUES (1, 'mem1', NULL) INTO test_A VALUES (2, 'mem2', NULL) INTO test_A VALUES (3, 'mem3', NULL) INTO test_A VALUES (4, 'mem4', 1) INTO test_A VALUES (5, 'mem5', 1)
[code]....
As the actual data is huge, I need to know the best (least expensive) way to select each parent and then all its direct child ordered by member_id the output should look like:
i'm trying to use a collection in a select statement as a table, but i've got an error which i don't understand.
This exemple is very simple. I'm trying to validate the solution. The object will contain the result of a query from a big table, and i have 4 request to make on it. I don't want to select 4 times the big table to get the result, but i need the whole result to make my requests (intersect, minus and union)

Is it a possible to create table using clause below together with index ?
create table the_table as select col1, col2 from table2
I got procedure which create a table in the schema B. The procedure is called from schema A. But when I write into procedure query for create index then I got a error:
ORA-01031: insufficient privileges when ...executing
Therefore I think about to create table together with index.
How does one select * from one table without selecting * from other tables that are included in a query? For example, if in the query below I want to view all fields in some_table, but not the fields from other_table, how do it?
select * from some_table st, other_table ot where st.id = ot.id
this is the correct syntax for updating a table with a select statement included. Table created easily and the alter table ran fine, but the update is running quite a log time.
My ultimate goal is to populate the "children" field with a count of children for each household id.
create table NON_GBC_Members nologging as select distinct hcp.household_master_ID from mrtcustomer.household_child_profile hcp where hcp.child_birth_dt between '31-OCT-2000' and '30-OCT-2011' group by hcp.household_master_id minus
I have a SQL statement that returns a set of columns...but...when I create table as <SQL statement> I get the same columns but with 2 of the columns containing each others data, e.g:
The SQL Select is correct and the Create Table As <SQL Select> is wrong.
Here is my SQL:
Create table ALTERNATENUMBERS as SELECT ctry, id, MAX(DECODE(tp,'EN', RN)) EN, MAX(DECODE(tp,'RN', RN)) RN, MAX(DECODE(tp,'AN', RN)) AN
[code]....
Unfortunately I cannot give you any data (too much of it) and small scale testing works, it's only when I run it on the 11million records do I get some (not all), just some of the data being mixed up between columns.
Now, I've tried:
1. Using SQLPLus - no joy
2. Creating the Table and then inserting the data into a blank table - also no joy
3. Using a VIEW - no joy, listagg doesn't work in VIEW tables
I do understand that without data it's hard to replicate the issue but why this statement works as a SELECT but when written to a table has data anomolies?
We have a large table of equally sized data blobs in our Oracle system and we'd like to select the whole table once into the memory. The corresponding tablespace is stored in SSD fast disks and is managed by ASM. However the achievable select speed (reading data into memory) of Oracle is not satisfactory. When we store the data in SSD disk using custom methods (e.g. in SQLite DB files) and load then into memory by multithreading (8 thread) techniques, the speed is more than 15 times that of Oracle.
Is there any way to optimize the oracle and ASM for increased full table select in our case. We tried FULL TABLE SCAN and PARALLEL hints and DB_FILE_MULTIBLOCK_READ_COUNT too, but with no success.
FYI:Our data blob is about 4.2kB and each DB_BLOCK_SIZE is 8kB. The ASM segment is configured for AUTO-ALLOCATE. The table is partitioned by HASH. Our oracle system is not RAC.
