I have to compare 2 tables on a columns's value.The 2 tables have same column as Regn_no.I just need to have the result in True Or False from a Query if the particular value of Regn_no is found in both the tables.
Temporarily I using a bit different and not good query which is as follows:
select count(*) from tab1 where regn_no in (select regn_no from tab2) and regn_no = 'UP78AN7890';
My tables looks like this:
Desc Table A (account)
Account1_id
Account2_id
name,
empid
Table B (Bill )
BillNo
Advertiserid
agencyid
total vvalue
I need to pick up total value from table B where the unique combination of advertiser-Agency id is the same as the given account1_id -Account2_id combination in table A for each employee id.
In other words my output should be like
Empid | Account_id (should be same as advertiserid)| Account2_id (same as agencyid) | sum(total_value) for this adv-agency combination.....
objective: Get the total value from table B for each unique account1-account2 combination (advertiser-agency in other words) .
I am not sure if I should use a correlated subquery or how to handle the situation....Right now I am just checking the two columns separately like this:
select.......from a,b
where b.advertiser_id = a.account1_id and b.agencyid = b.account2id
Is it correct to do so? I have a feeling that I am missing something if I join them separately like this.
I've a table (RelationshipX) with two columns with following values. The table represents the relationships. When I run the following query, It will give me all the combination of relationships...however, I need to get 15 unique as defined below.
Col1Col2
1106011060
1106011640
1106011142
1106011095
1106013029
1106014058
I run the following query to get below of all the combinaiton (note, I am opting out those six rows which matches to each other) select a.Col2 as Col1, b.Col2 as Col2 from RelationshipX a, RelationshipX b
where a.Col1 = 11060
and a.Col1=b.Col1
and a.Col2 <> b.Col2
order by Col1, Col2
[code]....
HOW can I modify my SQl so I get only 15 unique relationship records. (For example two UNDERLINE rows are technically same, and there are total 15 of them)???.
I need to compare columns of two tables in oracle 10g. If columns of both tables match with each other, then i need to create new table dynamically with matched column name and datatype. For example, table1 contains name, ID, Phone_no and address table2 contains name, Id, address, area and pincode. now , i need to create table3 which will contains name, ID,address, Phone_no, area and pincode as columns( I mean matched columns should not be repeated in table3). how to do this..

I have a STORES table and a STORE_REP table. Both tables have a column REP_ID.
I need to add a CHECK constraint into the STORES table to make sure that the info entered into its REP_ID column matches an entry in the STORE_REP table.
Both have a NUMBER(5) data type.
Will it make any difference if the REP_ID column in the STORE_REP table was originally created with a VARCHAR2(5) data type and was later converted to NUMBER(5), while the REP_ID column in the STORES table was created as NUMBER(5) when that table was created?
I want to compare two tables , and delete the common rows from the first table
Here is what i have done :
Create table test1(Test1C1 Number,

Create table test2(Test2C1 Number,
Test2C2 varchar2(50));
Insert into test1 values(1,'testdata1');
Insert into test1 values(2,'testdata2');
Insert into test1 values(3,'testdata3');
[code].......
it deletes all the records from Table test1. What should I modify here ? or should I write a different query ?
The desired contents in table test1 will be
2 testdata2
4 testdata4
6 testdata6
8 testdata8
10 testdata10
i wanted the query for the followin example
sample1

4 4 4 4
5 5 5 5
consider the above tables what i want is some thing like this
output
G H I J A

View 8 Replies View RelatedI am trying to get information about the columns of tables in Oracle databases. In MySQL, show columns provides good deal of information.But in Oracle, we do not have such equivalent call."describe" shows only the primary key.
But it does not show whether any column has unique constraint or an index.
I created a column in a table with unique constraint (but not a primary key), but it was not listed with CONSTRAINT_TYPE = 'U' in dba_constraints view, but was listed with CONSTRAINT_TYPE = 'C' - Check constraint.
I've recieved a recent request wherein the requirement is to swap values between columns across multiple tables in a database.Following is a visual sample of what needs to be done.

I have a large table with 450 column and we are only using nearly 170 columns and our BD block size is 8k.The DBA informed that there is an row chaining happening in the Database.My question is if we have data available in 170 column .why row chaining is happening.
The DBA informed us to remove the unnecessary columns .. Does those empty columns have any impact on the chaining.If we increase the size of DB block to 32k . does it will resolve the issue.
im trying to select columns from different tables dynamically in a function . The parameter for the function will be table name and column id's, In this number of columns may vary . Is it possible to have dynamic %rowtype to store the cursor value in it.

HISTORYSUMM_SNAPADM_CHOICE
My SQL code is loosely SELECT SUM(H.HIS1),
SS.SNAP1,
AC.ADM1FROMHISTORY H,
SUMM_SNAP SS,ADM_CHOICE ACWHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2GROUP BY SS.SNAP1,
AC.ADM1
This works, and I am able to SUM the column as I need with the right numbers. I altered the SUMM_SNAP table and now I want this summarized column to be in the table I tried using UPDATE, but there is no FROM clause to let me do the table join/group by
UPDATE SUMM_SNAPSET SUMM_SNAP.SNAP3=SUM(H.HIS1)FROMHISTORY H,
SUMM_SNAP SS,ADM_CHOICE AC
WHERE H.HIS2=SS.SNAP2AND SS.SNAP3=AC.ADM2
GROUP BY SS.SNAP1, AC.ADM1
The above is obviously wrong - but just trying to show whatI was thinking What would be the best method to get the numbers from the SUM into a table?

As the title of this topic illustrates, i'm having trouble dumping relevant data from columns of different tables. I am using isql*plus. I have three tables appropriatly related. A 'course' table, 'student' and 'next_of_kin' tables. I have many students enrolled on various courses but only a hanfull of courses offer the module option 'Database Systems'. I have no 'module' table but i know the three course names which provide the module option. I intend on producing a report hich lists all students enrolled on the courses which provid the module option 'Database Systems'.
I have attempted the report but i keep getting a 'cartesian product' displaying all next_of_kin names instead of the appropriate. Also i am struggling to come up with the right WHERE statement to depict only the three courses which provide the module option 'Database Systems' as defined by 'courseNo' in both 'course' and 'student' tables.
Here is the most recent attempt:
--set echo off
--set pagesize 24
--set feedback off
--set linesize 78
col A format 99999999 heading 'Student No'

View 4 Replies View RelatedI 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.
I have a two question.
Question 1:How to select all columns from table except those columns which i type in query
Question 2:How to select all columns from table where all columns are not null without type each column name which is in empty data
