Does Oracle have a package that can handle 'big number' (bignum) arithmetic, that is, decimal digits of 300 to 1000 characters in length, or more? I know 'binary_double' can handle E+308 but that is with precision.
A project here is looking at using prime numbers and we need to store the result of multiplying up to the first 950 or so prime numbers.
select employee_id,
last_name,
salary,
(salary + (salary * .155)) AS "NEW SALARY"
from store13.employees;
In the above example, I was able to get this to work. Now I need to add another column in the query (not the table) like this:
select employee_id,
last_name,
salary,
(salary + (salary * .155)) AS "NEW SALARY",
("NEW SALARY" - SALARY) AS "INCREASE".
from store13.employees;
This errors out. It seems to have a problem using the newly referenced column "NEW SALARY" to perform another math statement.
I wrote an query and regarding one part, i have syntax problem, when should we seperate different arithmetic operators in a query?
for example
select density_with_desert.popp / density_with_desert.arr - sum(darea) from counytyi don't want to use variables.
Is there anyway to compare the non numeric data in a table to a numeric number.Want to run a query like
SELECT rank_id
FROM mas_rank
WHERE rank_code > 26 Rank_code contains numeric as well as some non numeric data
I have a table which is updated with new records in each 15minutes from network. In order to get the accurate information I must do some arithmetic calculations on some variables.
For example, if the value for column A is 10 @9.45AM and 15 for @10AM the real result should be 15-10=5 for 10AM; because the values are cumulative so I need to subtract. Similar to this I have same operations for 9 more attributes in my table as well.
In order to handle this I used view and did necessary operations by using joining table like this (table name is Operations lets say and id is Primary Key)
create view ....
...
from Operations current, Operations prev
where current.datetime(+) = prev.datetime - 1 / 96
and current.id = prev.id
When I use this view, the simple select query takes about 15min since I have 25GB record for this table. What can I use instead of this join and solve cumulative values issue?
I am fetching data in the following set
NameWeight_LWWeight_TWChange
A56 56 0
B34 NULL -34
CNULL 77 77
Here Change=(Weight_TW -Weight_LW)
I should get values as 0, -34 and 77. But I don't get this as all operations with null gives null. These are fetched data and don't exist in the form shown. I have to use these row values of "Change" further. Is there any way of obtaining these results?
I am a novice in oracle
I have 2 columns in my table
->Col1 with experience in years entered as an integer
->Col2 with current date
I need to add another column as a date value adn for that i need to subtract Currentdate-Col1 when i tried currentdate-Col1 it just subtracted the days i need the formula to subtract years and give a date
I have worked in DB2 and all u need to do there was add the keyword years at the end but in oracle the same does not work
How to configure Oracle EM with newly created Oracle Instance on Oracle 10g DB,which is Single Instance DB but not RAC ,when I start the Oracle EM it is starting the default DB which created during Oracle Server Installation.
View 0 Replies View RelatedBut i do a lot of work-arounds to make sure the installation does not make corrupt my OracleAgent,OracleService and OracleDataGatherer. If i just let the installation do its thing i have problems with my libraries, and can't start anything.
The errors are : Procedure entry point 'BlaBla' could not be located in the Dynamic Link library 'AnyName'.
I notice that i have 2 versions of the libraries in OracleHomeBIN (one version 8, one version 11). The programs that start the OracleAgent,Service and DataGatherer call the old libraries but expect to find values that can be found only in new libraries.
I have a requirement to put together a Oracle SQL template to create re-usable DDL/DML Scripts for Oracle databases.Only the Oracle DBA will be running the scripts so permissions is not an issue.
The workflow for any DDL is as follows:-
1) New Table
a. Check if the table exists from the system/admin views.
b. If table exists then give message "Table Exists"
c. If table does not exist then execute DDL code
2) Add Column
a. Check if Column exists for a given table from system/admin views
b. If column exists in the specified table,
b1. backup table.
b2. alter table to make changes to the column
b3. verify data or execute dml script convert from backup to the new change.
c. If Column does not exist
c1. backup table
c2. alter table to add column
c3. execute dml to populate column with default value.
The DML scripts are for populating base tables with data required for business operations.
3) Add new row
a. check if row exists by comparing old values of each column with new values to be added for the new record.
b. If exists, give message row exists
c. If not exists, add new record.
4) Update existing record (We have createtime columns in these tables so changes can be tracked)
a. check if row exists using primary key.
b. If exists,
b1. deactivate the record using the "active" column of the table
b2. Add new record with the changes required.
c. If does not exist, add new record with the changes required.

This time i am downloading the Oracle 11g and then the Oracle APEX...(they are not in one package...right ? i mean they both have to download separately)i really new in oracle / PL/SQL. I'm not a programmer but i interest about database programming.For now i still use Ms. Access to develop an aplication and i really suprised i found this Oracle APEX because it an RAD tool too same as Access but more powerfull i think.

this is just a generic question. If a table has multiple Indexes on it say a table of 20 columns where 8 columns have indexes on it (each columns out of the 8 has an index on it and out of which three columns contain unique indexes on it).
If i run a query on this table where only two columns are specified in the where clause are the remaining 6 indexes on the table scanned during query execution.
I am facing problem with a select query in oracle 10g database from vb.net.It was working for oracle 9. The select statement I have written is as follows

I am trying to upgrade database from 9.2.0.7 to 10.2.0 in my test server. Here are the steps i am planning to do.
1. Export user data of production, Import in test db(ABC) using Destroy=Y Fromuser,touser parameter( this step just to refresh old test data)
2. Install 10g db, Use DBUA Utility of 10g to start upgrade>select 9i database which i want to upgrade
3. follow DBUA instruction ..create datafile paths, init.ora file, tnsnames,listener... same as the existing setup i have of 9i(so i can make replica of 9i in 10g)
question: I have another database(xyz) in test server its also in 9i, I don't want to upgrade that for now. so do i need to use one listener /tnasnames file of 10g and include setting of 9i in that 10g file ?
How to manage init,tnasnames,listener files setting in 2 db versions . Is there anything else i need to do to perform upgrade 9i-10g ? or its all ?
I will install just 10g database will import full export of 9i db. if i can do full import in 10g or should i just go for fromuser, tuser option to import? i believe for that i need to create datafiles, user,grant in new 10g db. I am not sure which option is best to perform 10g upgrade?
I've been told by management this weekend I will be required to perform a complete patch of our Oracle 11g database.
Problem is I really have never installed / patched Oracle. I'm able to access pretty much any database here and interact with it from a SQL stand point so since I'm the only person in my entire office who knows SQL, they decided I can become their full blow DBA.
Currently the database is running a unpatched version:
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

Once I download the latest patch (11.2.0.2.0) files from Oracle & perform a complete backup using RMAN:

How exactly does one properly patch / update Oracle 11g to the latest version?

View 4 Replies View RelatedOur Application is on Oracle 10g and we are going to migrate to Oracle 11g.
1) As of now we are using ojdbc14.jar. So if we migrate can we use the same jar or is it mandatory with 11g to use either ojdbc5.jar or ojdbc6.jar. I guess these jar version depends on the version of jdk we are using. But we are using jdk1.5 and still we use ojdbc14.jar which is working fine. So is it like , Oracle 11g can support only jdk1.5 or jdk1.6 ?
2) Is there any effect on the coding part if we change ojdbc14.jar to ojdbc6.jar ?I have seen there are some extra classes used in ojdbc6.jar.
3) Also we are going to migrate the Oracle database from Solaris to AIX. Our application lies on Solaris.So is there any compatibility problem , if our application lies on Solaris and database on AIX ?
