How to achieve that?
I want to join two columns, one with a Long and another with a Varchar2.
How to achieve that?
Have table with two columns with datatypes as number and varchar and the values in A column like 1,2,3 AND B column values like a,b,c. Now need to display data in a single column as 1,a,2,b,3,c.

Oracle v11.1 Standard edition. I am trying to use TRIM function around the columns which are used for outer join and it's not working. However, if I use ANSI syntax, it works. Please check the SQL below.Is there any way, I can use old syntax and TRIM and get the outer join to work?I know, I can fix/trim the data in the tables, but for some reason (need to keep the data exactly same as we received it), that is not possible here.

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'

I have a column in a database that contains both numerical and char data. I would like to be able to do two different things (two different queries)
1. divide the numerical data in the column by 10 and leave the char data alone (just return it)
2. detect the numerical data in the column and treat is as a different value so I can run averages & counts on it while disregarding the char data
I'm not at all sure how to do number 2. I thought a CASE statement would work for number 1, but then I realized CASE doesn't like different datatypes:
select
case when '1234' = 'checked' then 'checked'
when '1234' = 'gen.nograde' then 'gen.nograde'
when '1234' = null then null
else '1234'/10 end as "GRADE"

On DB 11.2. I am dynamically building a DB after update trigger that compares old/new column values. I wanted to include a nvl statement in my if conditions as some field values may be blank.
Since I have many different datatypes (varchar,date,number,blob,clob), is there a single nvl comparison I can use that will work against all of these? I was hoping not to have to check the datatype and change my nvl comparison depending on what type it is. i.e.
nvl(x,'1') or nvl(mydate,sysdate)

There we have two tables: my_comment and sys_comment.And field comment_desc in table my_comment is CLOB, and in table sys_comment is VARCHAR.
And I can run following two SQL successsfully:
SELECT comment_desc FROM my_comment;

But when I do UNION of them, execute following SQL:
SELECT comment_desc FROM my_comment

I'm new to XML to Oracle data integration. I do have clob column that has the XML data and trying to bring it into the Oracle relational tables, as a part of it we are developing PL/SQL procedure that calls this CLOB column, I want to know if we can variablize the data types ( Just like tablename. column name%type) in the select of the XML data:
select v.instrid, v.endtoendid, v.txid, v.cd, v.ccy,
replace(v.intrbksttlmamt,'.',',') as intrbksttlmamt, v.chrgbr, v.bic1, v.nm1, v.adrline11, v.adrline12, v.ctry1, v.iban1,
v.bic2, v.bic3, v.nm2, v.adrline21, v.adrline22, v.ctry2, v.iban2, v.cdtrref, v.addtlrmtinf
from the_data w,
xmltable(xmlnamespaces(default 'urn:iso:std:iso:20022:tech:xsd:pacs.008.001.01'),
[code]....
I do define the data types after every column name , the problem is incase there is change in datatype I do need to manually edit the procedure to change the datatype is there a way I can variablize them something like tablename.columname%type.
My table looks like this ->
Dp_value
124325
2434
3536
3536
Code is ->
(case when CL.DECIMALPLACES = 0 and CL.FIELDTYPE = 'D' and cl.DATATYPE = 'N'
then trim(dp."Value")*1000
else dp."Value" end) as dp_value,
What I am trying to do ->
From another table cl I want to say if decimal place is 0, fieldtype is decimal (D/C) and datatype is number (N/T)then multiply the number with 1000.
If not then leave it as it is.
When I run my code I get the error:
ORA-00932 : inconsistent datatypes: expected NUMBER got CHAR
for else dp."Value" end)
I would like to run below query on all tables, however it doesnt work on clob and long datatypes
select * from owner.table_name
minus
select * from owner.table_name@remote_db;
from dba_tables
where owner in ( '....');
ORA-00932: inconsistent datatypes: expected - got CLOB
How can I compare the data of clob and long datatypes using dblink ?
We are using Oracle Streams for replication.
Column datatypes in some of the tables on Source and Destination are different (Number on Source and Varchar2 on destination).
Do we have to create any rule or dml handler to handle this or Streams will automatically take care of it?We are oracle 10g.
Lets say I have three tables t1 and t2 and t3.
SELECT * FROM T1;
Id
____
1
2
3
4
SELECT * FROM T2;
Id
____
1
SELECT * FROM T3;
Id
____
1
Now when data exists in T2 and T3, I want to return only the records in T1 that match the records in T2 and T3 which is basically a normal join
select t1.id from t1, t2,t3 where t1.id = t2.id and t1.id = t3.id
However when there are no records in T2 or T3, I want to return all records in T1 i.e 1,2,3,4
One way of doing that is using the not exists clause
select * from t1 where not exists ( select null from t2 where t2.Id != t1.id) and not exists ( select null from t3 where t1.Id != t3.id)
Is there a better way of doing this in sql ?
I want to create a report by using one field and one text as columns name in layout but display the all the columns. I mention the 5 column names in query.how can I write function in summary column.
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
i want to know the difference between Left outer join Vs. Right outer join? Its like which join is safer to use or is there any recommendations to use any join?

I need to join 2 tables based on first match.. I cldnot use distinct on the result, as distinct work with entire row..
I cant use group by as well, since for group by hv to select all the columns which we need to display
I have 2 tables SEC_MASTER_HISTA and SEC_MASTER_HISTB.
Now, I need to compare the data of the two tables column-wise.
Ideally the 2 tables should have the same security_alias values but in my case they do not as the two tables belong to 2 diff client models. There is however a main SECURITY_MASTERA and SECURITY_MASTERB tables which have the security_alias recorded and a primary_asset_id column value which can act as a link between SEC_MASTER_HISTA and SEC_MASTER_HISTB. But, I have not been able to figure out the exact query which will be ideal.
Attached are the table structures and the data it contains.
Note: I need to compare the Coupon and Freq column values of SEC_MASTER_HISTA and SEC_MASTER_HISTB.
The existing format of the records are
