SQL & PL/SQL :: Different Number Of Result Sets While Adding Further Columns In Select Clause
May 4, 2010
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
[code]....

I have a table with around 80 columns. All i need is to select first 40 columns.
Is there any way to select first 40 columns without giving all the 40 Column Names in select clause.

I have two queries. One selects 5 values (all number datatypes), the second query selects 2 values (both number datatypes).If a value from query 2 exists in the resultset of query 1 - go make table updates using the second value in the select statment of query 2. If there is not a match, update a table with values from query 1.
Currently, I have two cursor for loops, which are nested. This works but of course is horribly slow. What is a better way to process this data?The number of rows varies between the two resultsets.

I have the following Union All query. It throws the following error in SQL plus
ERROR at line 27: ORA-01789: query block has incorrect number of result columns
After doing some google for the above error it suggests there are incorrect number of columns in the Union All query.I could not figure out the exact location well SQl Plus says error is on line 27 at the first opening bracket like
(Select distinct c.contact_code
Following is the SQL query
Select
tbl_contact.contact_code,
contact_title
||'.'||contact_name contact_name,
contact_address,

I am trying to write a single SELECT statement that groups at 2 levels of aggregation (using grouping sets) and assigns row numbers (to rank each item) that are partitioned at the correct level for each grouping set. I have the grouping sets figured out but I can't find a way to make Partition By match each level of aggregation.
What I am looking for (in a single SELECT statement) is logically equivalent to:
SELECTweek
,region
,NULL as country
,item
,SUM(qty)
,ROW_NUMBER OVER (PARTITION BY week, region ORDER BY SUM(qty) DESC) as rownumFROM base
GROUP BY week
,region
,item
UNION ALL
SELECTweek
,NULL as region
,country
,item
,SUM(qty)
,ROW_NUMBER OVER (PARTITION BY week, country ORDER BY SUM(qty) DESC) as rownumFROM base
GROUP BY week
,country
,item
I hoped that I could do something like this:
SELECTweek
,region
,country
,item
,SUM(qty)
,ROW_NUMBER OVER (PARTITION BY week, GROUPING SETS (region, country) ORDER BY SUM(qty) DESC) as rownumFROM base
GROUP BY week
,GROUPING SETS (region, country)
,item
But it looks like I am not allowed to partition by grouping sets -- I get the error ORA-00907: missing right parenthesis. I didn't expect it to work but I am not sure how else to partition by multiple levels.
let me know if I could have tagged my code or met other forum standards better.

I am trying to run an SQL query which refers/joins around 10 tables.In my case I would want to add an if-else or case condition in the WHERE clause of select query
For example
select a.column1, b.column1, c.column1, d.column1
from a, b, c, d
WHERE a.column2 = b.column2
AND (if a.column3 = 10 then ( I want 2 conditions to be
AND b.column2 = c.column2) added
else after WHERE clause as AND...)
AND b.column2 = d.column2
)
AND d.column2 = a.column2

I am running a fairly busy Oracle 10gR2 DB, one of the tables has about 120 columns and this table receives on average 1500 insertions per second. The table is partitioned and the partitioning is based on the most important of the two timestamp columns. There are two timestamps, they hold different times.
Out of these 120 columns, about 15 need to be indexed. Out of the 15 two of them are timestamp, at least one of these two timestamp columns is always in the where clause the queries.
Now the challenge is, the queries we run can have any combination of the 13 other columns + one timestamp. In reality the queries never have more than 7 or 8 columns in the where clause but even if we had only 4 columns in the where clause we would still have the same problem.
So if I create one concatenated index for all these columns it will not be very efficient because after the 4th or 5th column the sorting would no longer be very useful and I believe the optimiser would simply not use the rest of the index. So queries that use the leading columns of the index in sequence work well, but if I need to query the 10th column the I have performance issues.
Now, if I create multiple single column indexes oracle will have to work a lot harder to maintain all these indexes and it will create performance issues (I have tried that). Besides, if I have multiple single column indexes the optimiser will do nested loops twice or three times and will hit only the first few columns of the where clause so I think it will kind of be the same as the long concatenated index.
What I am trying to do is exactly what the Bitmap index would do, it would be very good if I could use the AND condition that a Bitmap index uses. This way I could have N number of single column indexes which the optimiser could pick from and serve the query with exactly the ones it needs. But unfortunately using the Bitmap index here is not an option given the large amount of inserts that I get on this table.
I have been looking for alternatives, I have considered creating multiple shorter concatenated indexes but this still would not address the issue since many queries would still not be served properly and therefore would take a very long time to complete.
What I had in mind would be some sort of multidimensional index, I am not even sure if such thing exists. But essentially it would be some sort of index that could serve a query efficiently regardless of the fact that the where clause has the 1st, 3rd and last columns of the index.
So considering how widely used Oracle is and how many super large databases there are out there, this problem must be common.

how to incorporate counts into my current SQL code that would count food items, and then car items for each person. Once I understand this concept I hope to apply it to my real database (in Oracle) where I am counting medications and problems for each patient.For example using my test data below, the my goal would be to have count columns show that Cathy had 3 food count and a 1 cars item (the count would need to ignore the null values in these columns). I don't really care if the count value repeats in every row for that person.
Select data1.Name, data1.Category,Data1.Results,Case When data1.Category IN ('food') then data1.results end FOOD,Case When data1.Category IN ('Cars')then data1.Results end CARSFROM(Select T1.name Name, null Category, null Results from a_Main T1, a_Food T2 Where T1.cpi_seq = T2.CPI_SEQUNION Select T1.name, 'food', T2.Food from a_Main T1, a_Food T2 Where T1.cpi_seq = T2.CPI_SEQUNIONSelect T1.name, 'cars', T3.Cars from a_Main T1, a_Cars T3 Where T1.cpi_seq = T3.CPI_SEQ)data1where data1.Category is not nullorder by Name,

when in sqlplus I execute:
select * from mytable;
in sqlplus I get the returned rows of this table. But this is not the case when I do in plsql the following:
create or replace procedure myproc is
a varchar2(50);
begin
a := 'select * from mytable';
execute immediate a;
end;
there is nothing I can see. Is there a way to catch this result set and see it on the screen? Something that is not creating new structures like cursors, etc?

I have procedure that is used by trigger but I define it as Varchar2 it's result show number.
change my PLSQL to use as varchar,
If trigger fired, the procedure make this query
select CB_SMS_FLAG, CB_SMS_DT from TM_SFS_CUST_04 where CUST_NUM = 01071234151;
but I want this query
select CB_SMS_FLAG, CB_SMS_DT from TM_SFS_CUST_04 where CUST_NUM ='01071234151';
because CUST_NUM is VARCHAR2(12)
so it can use index appropriately.
how can I change my PLSQL this sentence,
v_sel_sql1 := 'select CB_SMS_FLAG, CB_SMS_DT from ' || pTBL_NM ||' where CUST_NUM = ' || pCUST_NUM;
Here my code
CREATE OR REPLACE PROCEDURE ORAASFS.P_TM_SFS_CB_SMS_CNT_upd_104(
gKIND VARCHAR2,
pCUST_NUM VARCHAR2,
pSMS_CNT NUMBER,
pSMS_CLC VARCHAR2,
pRD_FLAG VARCHAR2,

this is my test data :
create table tab_1(c1 number,c2 number,c3 number);
create table tab_2(c1 number,c2 number,c3 number,c4 number,c5 number,c6 number);
insert into tab_1 values(1,1,1);
insert into tab_1 values(2,2,2);
insert into tab_2 values(1,1,1,3,3,3);
insert into tab_2 values(2,2,2,4,4,4);
The final result would be, update columns c1,c2,c3 from table tab_1 whith the values of columns c4,c5,c6 from tab_2 where tab_1(c1,c2,c3) exist in tab_2(c1,c2,c3).
My first aproach was :
merge into tab_1
using (select c1,c2,c3,c4,c5,c6 from tab_2) tab_2
on (tab_1.c1=tab_2.c1 and
tab_1.c2=tab_2.c2 and
tab_1.c3=tab_2.c3
)
[code]....
but gets error : ORA-01779
create table temp_table as
select tab1.c1,
tab1.c2,
tab1.c3,
tab2.c4 new_1,

SELECT * from TABLE_1 where a=b;
Is it possible to make the SELECT (PL/SQL is OK ) wait/block in case there are no rows found until another session inserts rows that match the condition?
Something like this
cursor c is select * from TABLE_1 where a=b order by column_a for update skip locked;
row c%rowtype;
begin
open c;
[Code].....
Or the INSERTing session should send some kind of notification (semaphore?) to the reading session?

I have a query that returns 11 Million rows but not all of them can be displayed in SQLDeveloper or DBVisualizer because of limited memory or other type of issues. I need to copy the entire result set to excel for further calculations.
Is there any way that i can select N number of rows out of my actual result set.
For example:
a) A result set contains 10 Million rows in total.
b) I want to display first 5 Million rows by executing a query
c) Then I want to display the remaining 5 Million rows by executing the query again with any parameter changes.
So all I want is to extract the rows of my actual result set in two or more executions, depending on the number of rows.
