I've a table where I've to select the greatest value from each row.
create table find_max ( colA number, colB number, colC number );
insert all
into find_max values (8,12,13)
into find_max values (-1,-22,3)
into find_max values (1,null,13)
into find_max values (-1,-2,-3)
into find_max values (-1,0,-10)
select * from dual;
the desired format of output is:
three fields for colA, colB, colC and max_value
max_value for 1st row is 13, 2nd is 3, 3rd is 13, 4th is -1,5th is 0.
how can I find the max_value without using any built in functions??
In sql plus How do I get the number of distinct rows of a certain value?
for example
select group_number from records group by group_number
How would I query for the total number of group_numbers in this query?
I have a column COL1 in table TAB1 which is varchar2. I want select only rows which has number and not alphanumeric value? I don't want to use regexp for this since

I have the following table:
FOOTBALL PLAYERS < ID, NAME, ATTRIBUTE>
100-JIM-TALL
101-BOB-STRONG
102-MARK-SMART
...etc
I want to form a query that regardless of the total returned records, I will be able to specify how many of each "kind" of players I want returned. There are several good reasons that it has to be one query and not many.
The query below returns 101 rows. If I replace the column list with an asterik the query returns 892 rows. I do not understand why.
--select *
select Ref_Consultant_CD
,Resident_CD
,ID
,Ref_Facility_CD

I am confused with third one.
CODE1. >> Comparing two strings >>
SQL> select greatest('99' ,'100') from dual;
GR
99
2. >> comparing both numbers >>
SQL> select greatest( 99 ,100) from dual;
GR
100
3.>> Comparing string and number >>
SQL> select greatest('99' ,100) from dual;
GR
99
whats the logic behind 99 being returned for thirdone.
I am facing a problem in bulk insert using SELECT statement.My sql statement is like below.
strQuery :='INSERT INTO TAB3
(SELECT t1.c1,t2.c2
FROM TAB1 t1, TAB2 t2
WHERE t1.c1 = t2.c1
AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery...These SQL statements are inside a procedure. And this procedure is called from C#.The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is 70. But in the next time call (in the same transaction) of the procedure, the number rows inserted is only 50.And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.I am using Oracle 10g R2 version.
I need to export large number of records from select into the text file. It's about 2milion records.I can do it by PLSQL (see below) where executing of process takes time too much. How to export to text file faster?
DECLARE
fileid UTL_FILE.file_type;
BEGIN
fileid := UTL_FILE.fopen ('VRS_CEM', 'cust.txt', 'W');
UTL_FILE.put ( fileid, 'IMSI|MSISDN|CONTRACT');
UTL_FILE.NEW_LINE(fileid);
[code]....
The below sql is giving different number of result sets while adding further columns in select clause.i.e After adding the columns 4,5,6 in the below query its giving different number of result set.In this case the result set count would be 5.
Before adding the columns 4,5,6,the result set count was 11.
SELECT PAYMENT_METHOD_MAP.NETTINGGROUP_ID,
PAYMENT_METHOD_MAP.CREDITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.DEBITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.AGENT_ID,
SETTLEMENT.NETTINGGROUP_ID,
SETTLEMENT.SETTLEMENTDATE

When i'm sorting on a calculated field i'm getting the following error:
ORDER BY item must be the number of a SELECT-list expression
I am importing some data from Oracle into another database on a regular basis. It works fine for most of the queries but couple of queries don't work sometimes (random). I don't get any errors or any data.
We switched on the Oracle auditing to find out the queries being sent to oracle db. We can see all the queries in the Audit log. Is it possible to configure Auditing to get the "Number of Rows" returned by Select statements so that we can be sure that some data was returned.

I have the below data in table test_1.
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 have the same problem like in below link

I have got a procedure that successfully creates an oracle external table and populates it with the contents of a file. This works fine until I have a situation where one of the fields is a VARCHAR2(2) and I try to insert say, a 5 character value. When this happens the record in question does not get populated in the external table (and rightly so), but I could do with working out if there is a discrepancy in the number of records in the file and the number of records that actually make it into the table so I could inform the user that there is a problem.
I have attached the code that creates the external table and populates it.
Below is my table structure.
create table test_join (
user_name varchar2(20),
attribut varchar2(30),
attribute_val varchar2(30)
);
[code].......
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 ?
I have requirement where I need to use a regular select statement for a PL/SQL table. How can I do this? Here is a code example:
Create or replace PACKAGE cv IS
type comp_rec is RECORD
(deptno number,
[Code]....
In the function AAA, I am trying to return a ref cursor. I want to base the ref cursor on a PL/SQL table rather than a Oracle table. But unfortunately
open temp_cv for select * from temp_tbl;
is erroring out.
Can I do this?? that is, use a PL/SQL table in a regular select. If not, then, is there a workaround ?
I want to find out all the tables that contains a known column name?
I know a column name called 'receiving_number', but don't what what table it's in.
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?
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.
Here is the code :
DECLARE
v_VerTabName VARCHAR2(30);
v_Minor NUMBER(2);
[Code]....
But when I compile this I get ORA-00936 : Missing expression at the EXECUTE IMMEDIATE line.
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 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..

query to know number of columns in a table i.e.
if I want to know how many number of colums are present in a specific table then what would be the query.
I created table that is range partitioned:
CODEPARTITION t1p1 VALUES LESS THAN (TO_DATE('2011-11-01', 'YYYY-MM-DD'))
PARTITION t1p2 VALUES LESS THAN (TO_DATE('2011-11-02', 'YYYY-MM-DD'))
....
PARTITION t1p4 VALUES LESS THAN (MAXVALUE)
Every year partitions will be added for next 12 month. The table partition will be dropped every month (I have to have data from last six month so in July I could drop partition t1p1, in August - t1p2....). How many tablespaces should I create for this table and how place partitions in them to have data for last six month and use minimum space on disk?
I was thinking about one tablespace for whole table because space of each dropped partition will be reused, what do you think about that?
Can we select table's rows of 5 to 15, like

It is through an error when i used the below method.
select * from emp
where rowid >=5 and rowid <=15;
