Give this a shot:
SELECT table_name,count(*) as "# of Columns"
FROM dba_tab_cols
WHERE table_name = <table name>
GROUP BY table_name
ORDER BY table_name;There are other views as well such as USER_TAB_COLS and ALL_TAB_COLS.
HTH!

How can I find number of columns in a table using a query
Hi
I want to find the number of columns in a table using a query.
Any help in this regard is much appreciated.
CheersHi,
This is the output i get when i executed ur query
OWNER OBJECT_NAME OBJECT_TYPE
SMLDBO T2311_SURVEY_QUESTIONS TABLE
select OWNER,OBJECT_NAME,OBJECT_TYPE
from all_objects
where OBJECT_NAME = 'T2311_SURVEY_QUESTIONS';
works Fine.
But if i use the below query it returns : 0
SELECT count(*) FROM user_tab_columns
WHERE table_name =upper( 'T2311_SURVEY_QUESTIONS');
What could be problem.
The table exists + name of the table is correct + it resides in my schema itself.
Any guess !!! -
ORA 01792 maximum number of columns in a table or view is 1000
Hello every1, I wish to register a large xmlschema doc, I am using the command
begin
dbms_xmlschema.registerschema(
schemaurl=>'xxxx',
schemadoc=>bfilename('XMLDIR','xxxxxx.xsd'),
csid=>nls_charset_id('AL32UTF8'));
end;
But the schema file exists 1000 col and it gives me the error msg of
ORA-01792: maximum number of columns in a table or view is 1000
is there anyway to solve the problems without edit the original schema document?

Maximum number of columns in a table
Hi all
I want to know the maximum number of columns in a table. Every people say either don't no? or else some are saying some number. Please can any body help me.

or else some are saying some numberThen why not read the documentation ? -
Maximum number of columns in a table or view is 1000
Post Author: TinaReifer
CA Forum: Formula
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...

Hi,
I am developing an application using jdbc. Is there any method which returns the number of columns in a table.
Thanks
Malloactually, this exact code is posted in the docs that I gave the link to:
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM TABLE2");
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();Jamie -

with a spreadsheet, I want to know the Last
column of the table
please help me ??i have a table in Excel file and i want to add the last column of this table in datagridview
i want to set ShtRange to give me the last column
i use this but don't give me a result
With Form1.xlWorkSheet
Dim ShtRange As Range
Dim dt As New System.Data.DataTable
ShtRange = Form1.xlWorkSheet.Cells(1, Form1.xlWorkSheet.Columns.Count).End(XlDirection.xlToLeft)
For Cnum As Integer = 1 To ShtRange.Columns.Count
dt.Columns.Add(New DataColumn(TryCast(ShtRange.Cells(1, Cnum), Excel.Range).Value.ToString()))

Maximum Number of Columns that adf table can support in JDeveloper 10.1.3.1
Hi All,
I'm using Toplink 10.1.3.1 . In JDeveloper 10.1.3.1 .
I'm Trying to display the columns of a table which is having the more than 380 columns.
When I'm trying to display the columns in adf table, it is getting hanged. The console of the displaying that "too long".
If Execute the Application with nearly 50 columns, It is working fine.
what is the Maximum number of columns that adf table can support. Is there any other solution for my problem.
could anyone help me out.
Thanks in advance,
regards,
SatishHi,
I am not sure there exist a limitation in columns and if the application hangs then this probably is a bug either in the business service or the view (which can also be due to that the server runs out of memory because of the created object instances).
However, in my opinion a table with 380 columns is a loud cry for denormalization

Edit:
Dear thread users!
You have here (in my post in this thread - see above) good example for inappropriate post in one thread.
I posted to fast - I didn't realise am I sure what I wrote!
Consequence was that, after posting, I asked myself is it correct my statement about rights on SYS-objects, I started to search for answer, etc.
So what I want to say is: if you don't want to find yourself foolish, like I found myself, don't post before you are sure is it correct what you wrote!

Limitation for number of columns in a table
What is the maximum number for the number of columns in a table or a view?
jHi,
The maximum number of columns that can be created in a relational table is 1000. Look at the documentation for more details.
Excerpt from the Oracle9i SQL Reference Release 2 (9.2) documentation:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_73a.htm#2061431
"The absolute maximum number of columns in a table is 1000. However, when you create an object table (or a relational table with columns of object, nested table, varray, or REF type), Oracle maps the columns of the user-defined types to relational columns, creating in effect "hidden columns" that count toward the 1000-column limit."
Please post database related questions in Database-general forum for quick response.

Hope that helps.

How to know number of columns used in a cursor
Hi,
I am using some query in a cursor.
I want to know the number of columns used in that query.
Please let me how to do ?
This is required because I want to export an oracle report into MS Excel.
For this I need to know, upto which column I should write in excel cell.
I am using Oracle 9i
I hope, I am clear in my requirement.

SurendraYou could use DBMS_SQL.DESCRIBE_COLUMNS :
SQL> CREATE OR REPLACE
2 FUNCTION column_count(
3 p_stmt VARCHAR2
4 )
5 RETURN NUMBER
6 IS
7 v_cur NUMBER;
8 v_cnt NUMBER;
9 v_rec_tab DBMS_SQL.DESC_TAB;
10 BEGIN
11 v_cur := DBMS_SQL.OPEN_CURSOR;
12 DBMS_SQL.PARSE(v_cur,p_stmt,DBMS_SQL.NATIVE);
13 DBMS_SQL.DESCRIBE_COLUMNS(v_cur,v_cnt,v_rec_tab);
14 DBMS_SQL.CLOSE_CURSOR(v_cur);
15 RETURN v_cnt;
16 END;
17 /
Function created.
SQL> SET SERVEROUTPUT ON
SQL> EXEC DBMS_OUTPUT.PUT_LINE('column_count is ' || column_count('select * from emp'))
column_count is 8
PL/SQL procedure successfully completed.
SQL> EXEC DBMS_OUTPUT.PUT_LINE('column_count is ' || column_count('select min(sal),max(sal) from emp'))
column_count is 2

Query to know number of executions of one day
Hi,
i need a query to get number of executions of the sql per dayWhat database version ?
You mean there is one sql statement you want to check daily executions ? Does it have the same sql ID each time ? If so then you could select from v$sql / v$sqlarea every 24 hours and compare counts from the previous runtime.
Are you collecting statspack and awr snaps ? If so then you may be able to run a report to view executions in 24 hour periods. -
Dynamic Number of Column in a table
Hi guys,
I have a requirement that needs dynamic number of column in a tale.
It is possible to do this in Adobe forms.
Thanks,
ChirantanHello. It of course is possible in Adobe.
You need to write a simple script using JavaScript or FormCalc to hide or show columns according to some special value. You will work with the presence attribute of the object. E.g. MYFIELD.presence = "visible" or "hidden" or "invisible". You will need to change your subforms content to flowed.
Use these guides:
http://www.adobe.com/devnet/livecycle/articles/lc_designer_scripting_basics/lc_designer_scripting_basics.pdf
help.adobe.com/en_US/livecycle/es/FormCalc.pdf
Hope this helps, good luck, Otto -
Oracle Pivot query regardless of number of columns
Hi, I have a requirement to create a view by pivoting all records associated with primary record regardless of the number of records, but... the LEVELID marked as Primary must be the first column left to right. The order of columns left to right after that do not matter.
There can be up to 18 CODES associated with a CLM but the amount is variable.
Thank you for your time.
create table
id_levels
(clm varchar2(12),
code varchar2 (12),
levelid varchar2 (12));
insert into id_levels select '1','15','Primary' from dual;
insert into id_levels select '1','42','Secondary' from dual;
insert into id_levels select '1','44','Third' from dual;
insert into id_levels select '1','41','Secondary' from dual;
insert into id_levels select '2','3','Primary' from dual;
insert into id_levels select '2','4','Secondary' from dual;
insert into id_levels select '3','24','Primary' from dual;
insert into id_levels select '3','15','Secondary' from dual;
insert into id_levels select '3','15','Secondary' from dual;
insert into id_levels select '3','16','Third' from dual;
