Max Number of Colums in a table..

Hi All,
I Am using Oracle 9i version..
May i Know Maximum Number of Columns in a table. ? Is there any possibilty to extend that?
Advanced Thanking...

May i Know Maximum Number of Columns in a table.1000. But be aware that this includes also hidden columns! You might not even be able to extend to 1000 if you really needed to:
SQL> declare
str long;
begin
for i in 1..998 loop
str := str || 'a' || i || ' integer,';
end loop;
execute immediate 'create table t (' || rtrim(str,',') || ')';
end;
PL/SQL procedure successfully completed.
SQL> select count(*) from cols where table_name = 'T'
COUNT(*)
998
1 row selected.
SQL> create index t_idx on t (lower(a1), lower(a2))
Index created.
SQL> alter table t add (a999 integer)
alter table t add (a999 integer)
Error at line 21
ORA-01792: maximum number of columns in a table or view is 1000
SQL> drop table t
Table dropped.

How to set max. number of rows in a table?

Hi,
I'm working on a SCADA interface. In this application there are different tables with vertical scroll bar.
I prefer to make visible only the initialized rows (I've initialized 40 blank rows of a table with a string array). Since the window not contain all 40 rows but only 20 rows, I set the rows number of "table properties window" to 20; so I added a vertical scroll bar.
Now, when a user scroll the scroll-bar, he can view not only the 40 rows initializated, but an undefined number of rows.
There's a way to visualize only a limited number of rows?
Thanks in advance!

Max number of records in an internal table

Hi,
Can any one tell me what is the Max Number of records we can get into an internal table.
if you have any link of sap help on this please FWD.

Hi lakshmikanth,
Internal Tables as Dynamic Data Objects
Internal tables are always completely specified regarding row type, key and access type. However, the number of lines is not fixed. Thus internal tables are dynamic data objects, since they can contain any number of lines of a particular type. The only restriction on the number of lines an internal table may contain are the limits of your system installation. The maximum memory that can be occupied by an internal table (including its internal administration) is 2 gigabytes. A more realistic figure is up to 500 megabytes. An additional restriction for hashed tables is that they may not contain more than 2 million entries. The line types of internal tables can be any ABAP data types - elementary, structured, or internal tables. The individual lines of an internal table are called table lines or table entries. Each component of a structured line is called a column in the internal table.

Max number of columns in table for compression

i was told that 256 columns is the max number in a single table for oracle to do compression on table. Can anyone confirm this ?

I can't confirm it off the top of my head but if it is the case then it is documented at http://tahiti.oracle.com you can look it up yourself.
What I do want to weigh in on is the insanity of a table with more than 256 columns. I consider any table with more than 50 columns suspect, more than 100 likely a strong indication that someone understands little about normalization. Anyone contemplating 255+ columns should have their fingers removed from their keyboard by force if necessary.

What's the max number of columns a table can have on 32 bit OS & 64 bit OS

What is the max number of columns a table can have on 32 bit OS & 64 bit OS ?
Edited by: sameer naik on 02-Jul-2010 02:11

For TimesTen 7.0 and 11.2.1 releases the limit on the number of columns per table is 1000 for both 32 and 64 bit TimesTen. This can be found in the documentation under System Limits.

Max number of logical table sources

Hi,
I have one logical table based (a fact table) on 8 logical table sources. This is done to simulate some partitioning as my customer does not have an partition set up on data base level.
Anyway my challenge is that a request fired in answers does not seem to take all logical table sources into account when building the physical SQL.
The missing logical table source (the one not being part of the physical SQL) does not differ from the other logical table sources.
Is there a limit of how many logical table sources BIEE can handle under one logical table?
BIEE version: 10.1.3.4

Alastair,
thanks for replying.
The logical tables sources partition the data by year. The aggregation level is the same for all LTS, the check for using this with other sources at this level is set and I've tried to force a result from every LTS (not combined but each LTS for itself). Forcing the results is done by using a dashboard prompt in answers filtering on year.
The whole 'LTS-setup' works in combination with Oracle Warehouse Builder. What I mean by this is the following: In OWB I split the data from one table into 8 different tables, each containing 3 years of data (except for the oldest data where the number of years and amount of data will grow over time).
This is done by comparing values of a year column with the actual year. E.g. the most actual table would contain data for the years 2010 - 2008, the next would contain data for 2007 - 2005, and so on.
Now as the years in the different tables will change, I decided to establish an equaly changing counterpart in BIEE. Basically I defined some repository variables: actaul_year, three_years_ago, six_years_ago, 9_years_ago, etc.
The fragmentation content of the different LTS is defined like this:
most actual data: MyModel.Year.Year >= VALUEOF("3_years_ago")d
next table: VALUEOF("3_years_ago") > MyModel.Year.Year AND MyModel.Year.Year >= VALUEOF("6_years_ago")
next table: VALUEOF("6_years_ago") > MyModel.Year.Year AND MyModel.Year.Year >= VALUEOF("9_years_ago")
etc.
The funny thing is that the missing table is the one containing years 13 - 15. All the other tables (e.g. 16 - 18 years and 19 - 21 years) are represented in the physical SQL. This particular table is not even represented in the physical SQL.
I haven't yet tried to take one of the 'working' tables out to see if this helps (getting an idea if there is a limit on number of LTS per logical table).
Any idea?
Thanks
regards
Andy

Table's max number of rows

Hi,
I am a newbie to Oracle and I would like to get you comment of the following questions:
1. What it the maximun number of rows that a table should have in order to be adequately handled in the sense of Create, Read, Update and Delete?
2. To be more specific , let say I have the following table:
file_id (INT)
senetence_id (INT)
sentence (CLOB)
Primary key (file_id, senetence_id)
The queries I would like to do are:
select - select all sentences for a certain file_id
insert - insert a new sentence (for a specific file_id)
delete - delete a sentence for a specific file_id.
search - get all sentences that contain a specifc string
The table's size is going to growth and could get to millions and even more.
Could i get into a point where I couldn't "work" with the table.
Thank you in advance for your assitance

Hi,
Welcome to forums.oracle.com
I am not sure of what you are looking for, DB itself used for storing information irrespective of Size of data (as its going to increased day by day).
The queries I would like to do are:
select - select all sentences for a certain file_id
select *
from <table_name>
where file_id = <specific_fileid>
insert - insert a new sentence (for a specific file_id)
insert into <table_name>
select <specific file_id>, <sentence>,EMPTY_CLOB()
from dual
or
insert into <table_name> values (<specific file_id>, <sentence>,EMPTY_CLOB())
delete - delete a sentence for a specific file_id.
delete from <table_name> where file_id = <specific file_id>
search - get all sentences that contain a specifc string
select from <table_name> where file_id = <specific file_id>
I could not able to understand further, are you looking specific to CLOB in your table. ??

How to set naming standard that sets max number of words in column name?

Hi all,
Is it possible to set naming standard that sets max number of words in colum (or table) name?
I was looking video (1:08min)
http://download.oracle.com/otn_hosted_doc/sqldev/UserDefinedDesignRules/UserDefinedDesignRules.html
And here you can see how rule is triggered.
"...Name has 2 words; Max permitted - 1".
Thanks a lot

Hi,
you need to create glossary and set it in naming standards for your design.
This document is still valid - http://www.oracle.com/technetwork/developer-tools/datamodeler/datamodelernamingstandards-167685.pdf
Naming standard settings are located :
- DM 3.x - "Preferences>Data Modeler>Naming Standard"
- DM 4.0 - Design dialog>Settings>Naming Standard
If you want only check on number of words then glossary can be empty and you can set "Incomplete modifiers" option in that glossary.

How to find number of rows in a table

i have one table ,it contains millions of record,how can i know number of rows in that table without using count(*),
i tried in user_table ,for the column NUM_ROWS,but it is not showing number of rows,pls send me a solution for this.
regards,
singh

Ok, that only was to show simply that max option
might not an option to reduce execution time.Yes, but I/O variances have a tendency to really skew the observed elapsed execution time - making execution time alone a poor choice to determine what SQL will perform better than another.
Both MAX(ROWNUM) and COUNT(*) results in the same amount of I/O - as both uses the exact same execution plan, I/O wise. In this example, a FTS.
SQL> create table testtab nologging as select * from all_objects where rownum < 10001;
Table created.
-- warmed up the buffer cache with a couple of SELECTs against TESTAB in order
-- to discard PIOs from the results
SQL> set autotrace on
SQL> select count(*) from testtab;
COUNT(*)
10000
Execution Plan
Plan hash value: 2656308840
| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 35 (9)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | TABLE ACCESS FULL| TESTTAB | 9262 | 35 (9)| 00:00:01 |
Note

0 recursive calls
0 db block gets
131 consistent gets
0 physical reads
0 redo size
223 bytes sent via SQL*Net to client
238 bytes received via SQL*Net from client
2 SQL*Net roundtrips to/from client
0 sorts (memory)
0 sorts (disk)
1 rows processed
SQL> select max(rownum) from testtab;
MAX(ROWNUM)
10000
Execution Plan
Plan hash value: 2387991791
| Id | Operation | Name | Rows | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 35 (9)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | | |
| 2 | COUNT | | | | |
| 3 | TABLE ACCESS FULL| TESTTAB | 9262 | 35 (9)| 00:00:01 |
Note

2 SQL*Net roundtrips to/from client

0 sorts (disk)

So seeing that we have the exact same baseline for both queries, and that PIO does not influence the results, we time a 1000 executions of both.
SQL> declare

This shows that what makes the MAX() more expensive is just that - determining the MAX(). For each row, Oracle has to call its internal MAX() function with two values - the current max result and the new value. This function then returns the new max value. This overhead per row adds up to a significant overhead in execution time - making the MAX() approach 5x slower than the COUNT() approach.

I am trying to create a direct link from Tririga / Oracle database into Crystal XI. The data I am attempting to pull is from the RETransaction (Escalations). The error I keep receiving is shown below. Has anyone run across this problem and found a solution that can be shared?
Very Appreciative for any feedback.

Try posting your software, its version, and the type of connectivity you're using for oracle.
Older versions of Crystal used a proprietary Oracle ODBC driver that came with Crystal, but you should SWITCH away from using ODBC anyway, not sure why you elected to use it, it's slower and more problematic.
You'll see Oracle Server listed as a data source, that is generally the best connectivity to use.
Also, what version of Oracle is it, and what Oracle client are you using?
You might need your Oracle dbas assistance here.
Anyway, the error is not a Crystal error, it's being raised by the ODBC driver, and Oracle used to have a maximum of 1024 colums I think it was...been a while...

Max number of chars in process message MSEL?

Hi, what is the max number of characteristics can be used in process message category's MSEL table? Right now, I am using more than 99 characteristics and I get a short dump DYNPRO_FIELD_CONVERSION. Is it really limited to 99 characteristics and if it is true, is there an OSS note to change it to allow more than 99?
Thanks and points available

Please make sure that you build a
multithreaded program first (check with ldd).
If anyone can tell me the maximum number of threads per process I would
really appreicate it.
Also the maximum number of open files per process. It depends on the architecture (x86/SPARC), OS version,
64 or 32-bit, /etc/system, shell limitations (/usr/bin/ulimit) ...
Search for "rlim_fd_max / rlim_fd_cur" on docs.sun.com too.
