Max no of coumns in a table

Hi,
What is the maximum number of columns in a Table.
Many Thanks,

Hi,
For Oracle 9iR2 or 10gR1, it's 1000 columns max : http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96540/statements_73a.htm#2153106
Nicolas.
For 8.1.7 too, it's thousand columns max for one table.

  • Howto limit max. count of rows in a TABLES-based import-parameter?

    Hello all,
    I have created a web service based on a custom function module in SAP. Beside others this function module provides one TABLES input parameter, which is set to "optional". Now I want to publish the web service with this parameter optionally as well, but also allow it for max. 10 tmes (meaning max. 10 rows for this import table).
    I have found an entry for min and max settings in SE80 for this web service, but unfortunately these both fields are read-only, so I can't set the maxOccurs here.
    Any ideas how I can solve this problem?
    Thanks in advance for your help!
    Kind regards, Matthias
    Edited by: Matthias F. Brandstetter on Oct 21, 2010 10:32 AM

    Hi,
    It is not possible to change SAP generated service. Better you create new service in ESR and assign correct maxOccurs and then create proxy of this service in backend where you can also map ESR service to FM.
    To minimize effort you can copy same wsdl and then change wsdl and import in ESR as new service.

  • Optimized query to find Min and max of a col in a table

    I have a table doc_boe_rec with record count 12375934
    the primary key columns are (boe_rec_id,psd_serial_num).
    No other ndexes are present on this table.
    I want an optimized query which will give both the results :
    1.Min boe_rec_id (boe_rec_id from 1st record)
    2.Max boe_rec_id from this table with rows limited to a value say 5000.
    i.e (boe_rec_id from 5000th column value from table )
    Thanks
    Manoj

    1.Min boe_rec_id (boe_rec_id from 1st record)It is confusing for me. The min value for the first, hmmm...
    2.Max boe_rec_id from this table with rows limited to a value say 5000.Not more clear...
    Please details your requirements.

  • Max no columns allowed in a table

    i want to know how many columns are allowed in a table.maximum no of columns in table.

    I hope this will be helpful for query
    ORA-01792: maximum number of columns in a table or view is 1000
    Cause: An attempt was made to create a table or view with more than 1000 columns, or to add more columns to a table or view which pushes it over the maximum allowable limit of 1000. Note that unused columns in the table are counted toward the 1000 column limit.
    Action: If the error is a result of a CREATE command, then reduce the number of columns in the command and resubmit. If the error is a result of an ALTER TABLE command, then there are two options: 1) If the table contained unused columns, remove them by executing ALTER TABLE DROP UNUSED COLUMNS before adding new columns; 2) Reduce the number of columns in the command and resubmit.

  • 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 No. of Records in a Table

    Dear Sir/Madam,
    I have the Transaction table with 10 Million records. While Tuning the table it takes 5.8 seconds to fetch records from it with Cost based optimization. I have Partitioned my table based on months and necessary index is been created.What should I want to do to reduce this time.
    Is there is any way to get the Time duration (like. Estimated Time - 5.8 seconds) taken by a Query in SQL prompt itself.

  • Max No. of records in a table - performance related statistics of a table

    Hi all,
    Can anybody please help me on the performance related statistics depending upon the size of the table?
    I have a question regarding the scalability and(I think so) and performance.
    My record is having 20 columns and all columns together it will come upto around 200 bytes/record.
    What is the maximum no of records that can be stored in a table?
    Currently the table is having more than 500,000 records.
    Every month, 15,000 new records are added. A new requirement came up now. If that is implemented, no. of records per month will go upto 50,000.
    It means the table is getting filled up at more than three times faster every month.
    How this will effect my application's performance - Querying / Inserts / Updates ?
    Please help me.
    thanks and regards.
    Pandu

    There is no inherent limit to the number of rows in a table, I have several tables with over 20 million rows (and many of these are over 200 bytes per record).
    The performance impact of larger tables largely depends on how you access the tables. The size of the table will not really affect Inserts. Updates and Selects will become slower as the table increases, however, the magnitude of the impact will depend on how you access the tables. If most queries/updates go after single rows using a PK, then the impact will be minimal. If most queries/updates affect large numbers of rows using unindexed columns as selection criteria, then the impact is potentially huge.
    Depending on the nature of the data, and the way it is used, you may want to investigate partioning as a way of limiting the number of rows that need to be searched for any given query/update. Even with 500,000 rows currently and 50,000 a month coming in, you probably have several months to look at it before anything drastic needs to be done.
    Just make sure that you analyze the fast changing tables frequently.

  • Reg: Max no of triggers on a Table

    All,
    Could you please clarify me on, How many triggers we can apply on a table. As far as i know, there is no limit from 11g on wards, but not sure, before 11g it was only 12 ( 12 types of triggers).  Could you please provide me a link where i can check this in the oracle documentation.
    Thanks

    "Since you can define separate triggers on  different columns the only limiting factor will be based on the number of columns in the table."
    How the trigger will be limiting based on the no of columns in a table.
    Just a heads up for you and others that think there are shortcuts to learning.
    You aren't going to learn if you are unwilling to read the documentation or to try things for yourself.
    It is very easy to do both of those things so when people won't do them it gives the impression that they are lazy and just want other people to do their work for them.
    In an interview is is VERY easy to tell when you have one of those people in front of you.
    A simple web search for 'oracle 11g creating trigger' lists this link to the PL/SQL Langauge Reference as the second result
    http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/triggers.htm#BABCIBBJ
    At the top of that link is a list of the topics covered with a link to each of them. One of those topics is 'Creating Triggers':
    Creating Triggers
    To create a trigger, use the CREATE TRIGGER statement. By default, a trigger is created in enabled state. To create a trigger in disabled state, use the DISABLE clause of the CREATE TRIGGER statement. For information about trigger states, see Overview of Triggers.
    When using the CREATE TRIGGER statement with an interactive tool, such as SQL*Plus or Enterprise Manager, put a single slash (/) on the last line, as in Example 9-1, which creates a simple trigger for the emp table.
    Example 9-1 CREATE TRIGGER Statement
    CREATE OR REPLACE TRIGGER Print_salary_changes  BEFORE DELETE OR INSERT OR UPDATE ON emp
       FOR EACH ROW
       WHEN (NEW.EMPNO > 0)
       DECLARE  sal_diff number;
       BEGIN
      sal_diff  := :NEW.SAL  - :OLD.SAL;
       dbms_output.put('Old salary: ' || :OLD.sal);
       dbms_output.put('  New salary: ' || :NEW.sal);
       dbms_output.put_line('  Difference ' || sal_diff);
       END;
    Did you notice this line?
    WHEN (NEW.EMPNO > 0)
    So create a new trigger by changong the name of the trigger to Print_salary_changes1 but use this line
    WHEN (NEW.EMPNO < 0)
    Now do it again with a new name and use this line
    WHEN (NEW.EMPNO = 0)
    How many triggers are there now?
    Keep going as long as you like using a new name and a new line:
    WHEN (NEW.EMPNO IS NULL)
    WHEN (NEW.EMPNO = 11)
    WHEN (NEW.EMPNO = 22)
    WHEN (NEW.EMPNO = 33)
    WHEN (NEW.EMPNO = 44)
    How many triggers do you have now for just this one column?
    Keep going and let us know when Oracle gives you the exception 'TOO MANY TRIGGERS'.

  • How to find min and max of a field from sorted internal table

    Hi,
    I have sorted Internal Table by field f1.
    How do I find max and min value of f1.
    For min value of f1 I am using,
    READ TABLE IT1 INDEX 1.
    IT1-F1 = MIN.
    Is this correct? And how do I find the max value of f1 from this table.
    Thanks,
    CD

    Yes, that is right, and you can get the max like this.
    data: lv_lines type i.
    * get min
    READ TABLE IT1 INDEX 1.
    MIN  = IT1-F1.
    * get max
    lv_lines = lines( it1 ).
    read table it1 index lv_lines.
    MAX  = IT1-F1.
