(number Precision Too Large) Using POWER (n / M) Function?
Feb 14, 2012
POWER(47.3616, 27.1261) returns: 2.80403309600359E45 which causes "number precision too large" error in my variable which is defined as NUMBER(20,20).
I've tried ROUNDing and TRUNCing the product, but still get the same long output. The only thing that seems to work is SUBSTR.
Is that the ONLY way to deal with this? It seems like there would be a better way or is there another type I should use these super long decimal results?

I have created a function that is used for splitting a comma separated string & give the output in tabular form.here is the function
Here I have used CLOB as my input string will be huge(greater than max limit of varchar2)
CREATE OR REPLACE TYPE SPLIT_TBL_CLOB AS TABLE OF CLOB; CREATE OR REPLACE FUNCTION CSVTOSTRING_CLOB ( P_LIST CLOB, P_DEL VARCHAR2 := ',' ) RETURN SPLIT_TBL_CLOB PIPELINED
[code]....
But here I am facing 2 problems.
1. The function is not accepting a large string & I am getting the error
Procedure countyname(i_lat IN Number, i_lon IN NUMBER, o_countyname OUT VARCHAR2);
The procedure works fine when the input parameter values are small precision like 30.653, -618.765 etc.it fails if the Input parameter values have more precise like 35.694872140886...I think the IN Number can only take upto certain precission.
Is there any way I can specify the precision for a NUMBER input parameter in a procedure?
ex: Procedure countyname(i_lat IN Number(30,10), i_lon IN NUMBER(30,10), o_countyname OUT VARCHAR2);
when I tried the above statement it doesn't compile it gives PLS-00103 error.
We have truncated number based on the decimal value. i tried to truncate number based on the precision using cast function. i got an error "value larger than specified precision allowed for this colum".
create table TEST_NUMBER (id number(4,1)); insert into TEST_NUMBER values(1234.789888888888);
[code]...
ORA-01438: value larger than specified precision allowed for this column 01438. 00000 - "value larger than specified precision allowed for this column" *Cause: When inserting or updating records, a numeric value was entered that exceeded the precision defined for the column. *Action: Enter a value that complies with the numeric column's precision, or use the MODIFY option with the ALTER TABLE command to expand the precision.
I am working on an application that pulls data from an Oracle view into Microsoft Excel (Oracle 11g, MS Excel 2003). It is an automated pivot table created through vba. The problem I'm having is that the decimal points from number columns are being truncated - they don't make it to the pivot table.
When I use the pivot table wizard and set the external data source using a SQL string (select * from view), the precision is not lost. When I create the pivot table automatically in vba, the precision is lost. The pivot table settings, regardless of how the data is brought in, shows the format of the number column as general. This tells me that Excel is trying to figure out what the data type is, and can't (not smart enough).
When looking at the description of the view, the data type is NUMBER (no precision). The table that it is pulling from has the precision set (NUMBER(11,3)). I have tried using the following, but it doesn't work:
select to_number(field_name, '99999999.999') field_name from view
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.
Consider tables A,B,C,D,E,F. all are having 100000++ records Tables B,C,D are dependent on table A (with foreign key constraint). When I am deleting records from all tables, table B,C,D are taking max 30-40 seconds while table A is taking 30-40 mins. All tables are having indexes.
Method I have used:
1. Created Temp table
2. then deleted all records from B,C,D,E,F for all records in temp table for limit of 500. delete from B where exists (select 1 from temp where b.col1=temp.col1);
3. Why it is taking too much time for deleting records in table A.
Is there any thing that during deleting data from such master table, it is referring to all dependent tables even if dependent data is not present ?
I need to export large number of records from select into the text file. It's about 2milion records.I can do it by PLSQL (see below) where executing of process takes time too much. How to export to text file faster?
We are facing one issue on one of the database. The database is generating large trace files(14000) from last two days. That consumes around 15G space on the disk. And the content of the trace files is not having any meaningful message to debug:
*** TRACE DUMP CONTINUED FROM FILE /apps/oracle/admin/fs90uat/bdump/fs90uat_p050_23966.trc ***
... (Many lines with above message)
The alert log is having one repeated error yesterday:

The corresponding trace file is having error:

I have a report with single row having large number of columns . I have to use a scroll bar to see all the columns. Is it possible to design report in below format(half columns on one side of page, half on other side ofpage :

We converted our Power builder application from Oracle 10g to Oracle 11g. We are getting very slow to retrieveing data from the server.Basically we have noticed the following system internal sqls taking more time during our sql calls.

we have installed oracle database 11.2.0.3.0 using 12G for grid and 8G for DB. And now we want to apply the PSU 11.2.0.3.4, but found that there is not enough.
How much we need to upgrade to 11.2.0.3.4 totally?

When we are trying to create number data type column of a table with precision greater than actual value,it's accepting the definition of the table . But we are unable to insert any values into the table.how internally it stores the value

2114 rows I got the same result if I use NVL(o.scn,0) rather than TO_NUMBER(o.scn). I can't find out why this happens. Obviously, the ">" condition doesn't match when the difference is too small.
AFAIK, ora_rowscn is a NUMBER while my "scn" column is a NUMBER(12) (which should be sufficient to store my DB or remote DB's SCN).

I want Oracle stored function/procedure to calculate number of working days between two dates. We need to exclude Firdays and Saturdays as there are weekend holidays and also exclude official holidasy that lie between two dates.
