I want to Suppress the Dummy columns from the UNION Clause of Query.
SELECT
'HEADER' AS record_type
,null C2
,null C3
,null C4
,null C5
FROM dual
UNION ALL
SELECT empid
[code]....
Now I need to remove the all the Dummy fields associated to "HEADER" and "TRAILER" records.
I have inherited a query that union alls 2 select statements, I added a further field to one of the select statements ( a date field). However I need to add another dummy field to the 2nd select statement so the union query marries up I have tried to do this by simply adding a
select
'date_on'
to add a field called date on populated by 'date_on' (the name of the column in the first query)
however when I run the union query i get the error Ora-01790 expression must have same datatype as corresponding expression.
I have a view that contain multiple tables with ( UNION all ) clause , is there any way that if i query from this view I can explicitly specify the table that i need the data from ?
Let say i have view that contain salaries of 2011
Create view sals_2011 as select * from sals_jan2011 union all sals_feb2011 ..... union all select * from sals_dec2011.
if i issued select * from sals_2011 where emp_id >500 and date < 01-feb-2011 the explain plan show me that full tables and indexes are in processing, while i know that i need only to scan sal_jan2011, and of course it is taking much longer time than selecting from the original table only.
I am using oracle RAC 11g R2
Oracle version : 11.2.0.2 Linux EL6 server
I have a query like below:
select col1, col2, col3, col4
from tab1, tab2, tab3
where conditions
union
[Code]...
Now, the col4 is a date column and I have to order by the entire result sets on it. I know I can do it by (order by col4) or by (order by 4) at the end of the entire query.
But the problem is that, the output is coming in dd-Mon-yyyy (i.e 31-Nov-2012).
I want every output in dd/mm/yyyy format so I need to use to_char function.
But in that case, I cant use the order by clause, because in that case it is getting arranged by character i.e by 1,2,3,4,5 like this.
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.
Following is my table structure:
14:54:17 PYMTPRODIAT@UCS43 > select * from DGTEST;
ID AMOUNT DI
---------- ---------- --
1 50 D
2 50 D
3 20 D
4 60 C
2 60 C
3 20 C
now, I want the output in the following format.what could be the easiest way.. I need the output in one query,,
ID D_Net_Amount C_Net_Amount
--- ------------- --------------
1 50
2 50 60
3 20 20
4 60
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_address,

select * from nrc_trans_descr where type_id_nrc=60013 -- it has 18 columns and i have hard coded 60013 for simplification here.60013 is derived from 3 other table Output is ( it can have many rows too.typically for each type_id_nrc there is one row ).

i have to pass TYPE_ID_NRC and INSTALLMENT_TYPE_ID_NRC to restriction_id column in a different table. currently i am doing like this
select * FROM DISCOUNT_RESTRICTIONS WHERE discount_id in (12085,12086)
and (restricted_id in ( select type_id_nrc from nrc_trans_descr where type_id_nrc=60013)

am using ORACLE 10GR2(solution for 11gr2 is welcome too)
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,
[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,

This is a sample query with only 6 columns but my actual query has about 70 columns. Basically I need to be able to suppress those rows where numerical values are zeros across a row. But even if one column has a value greater than zero, I need that row. I am just trying to avoid creating a big WHERE clause with all fields in there.
with my_table as (
Select 'A' as org, 12 as val_1, 13 as val_2, 14 as val_3, 40 as val_4, 100 as val_5 from dual
union all
Select 'b' as org, 12 as val_1, 13 as val_2, 14 as val_3, 40 as val_4, 100 as val_5 from dual
union all
Select 'c' as org, 12 as val_1, 13 as val_2, 14 as val_3, 40 as val_4, 100 as val_5 from dual

View 8 Replies View RelatedI've created a change event dynamic action which fetches a description from the database for a user-entered code. When this is run in Firefox, a swirling loading image is displayed next to the description.However, the loading image causes anything displayed its right to be moved out and then back again when it disappears. On a form with lots of dynamic actions this can be quite disconcerting so I'd like to stop it.
Can a dynamic action's loading image be suppressed?
APEX inserts the following HTML alongside the input field:
<span class="apex-loading-indicator"></span>One option is to apply "display: none;" to the "apex-loading-indicator" class but this could affect other loading images that use the same class.
Note: This affects Firefox (18) but not IE9

View 1 Replies View RelatedIs it better to use UNION (or) UNION ALL with DISTINCT,Which one will improve performance.
Query1:
SELECT deptno FROM emp
UNION
SELECT deptno FROM dept
Query2:
SELECT DISTINCT * FROM(SELECT deptno FROM emp

SELECT deptno FROM dept)
I mean to say query1 is better (or) query2 is better,which query improves the performance.
can we use something like this
"select ... order by emp from emp"

I'm just trying to see if there is another way of doing this query without using a UNION. The only way I can see is using a UNION but maybe I'm missing something or a way to do it without a UNION.
Result:
Select any customer within the user_states table who lives in "MO"
Select any customer within the user_cars table who lives in "MO" and has a "White" car
Select any customer within the user_plates table who lives in "MO" and has a plate of "A" or "B"
Join to the user_names table to display the customers name
So, the result would be any customer who lives in "MO" who owns a "White" car and any customer who lives in "MO" who has a plate of "A" or "B".
SQL
select b.customer_id,
b.first_name,
b.last_name
