Max. No of Fields in a DBF Table

Hi All,
I want to know the Maximum number of fields i can create for record of a DBF using JDBC. Also I want to whether the created DBF can be accessed thru FoxPro or VFP.
Thanks in Advance to all.
Hari

I want to know the Maximum number of fields i can create for record of a DBF using JDBC.255.
Also I want to whether the created DBF can be accessed thru FoxPro
or VFP.Can't
I have a DBF with 503 fields, CDx and FPT.
Then one of my friend told that the dbf has been created using JDBC.
So I want to be sure whether i can create that much big DBF. Don't try. I guess that your DBF should be created by HXTT DBF, which supports about 30,000 columns for special utilization.
And I want to know which JDBC driver helps me to read the DBF.It's at http://www.hxtt.com/dbf.html

  • 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.

  • Changing Non key field to Key field in a custom table

    Hello Abap gurus:
    I have a requirement in which i need to change a non key field in my custom table(Z TABLE) to key field.
    For example; i have field sequence as
    field 1  key field
    field 2 key field
    field 3 key field
    field 4 non-key field
    field 5 non-key field
    field 6 non-key field
    field 7 non-key field.
    i want to change field 7 as key field.
    Can i do perform operation??
    when i am tryingto perform bove operation it is taking long time to get the table activated.
    Could any one please help me in getting this resolved.
    regards,
    Sravanthi.

    Use DB Utility (se14) to perform alter table or conversion. The latter is used when atemps to perform first operation fails. Which one is used, really depends on system and current DB table state (i.e. if has any content and what is being adjusted).
    The way Max suggested is similar to [conversion process|http://help.sap.com/saphelp_nw04/helpdata/EN/cf/21f1b8446011d189700000e8322d00/content.htm] which system takes care of itself.
    Refer [Adjusting Database Structures|http://help.sap.com/saphelp_nw04/helpdata/EN/cf/21f1ab446011d189700000e8322d00/content.htm] and already given link to conversion.
    Please also consider potential errors while doing conversion . This can lead to data loss, so you should think of some backup to prevent that.

  • Last access date of fields in sql server table

    Hello All,
    is there any queries to find last access date of all fields in sql server tables.
    because in our database table having no of field,most of fields are unused from long time.we want drop those fields from tables to make the table light.
    Thanks In Advance!!!
    mastanvali shaik

    Do the fields have indexes?
    In SQL Server 2005 you can use the sys.dm_db_index_usage_stats data 
    management view, look at the column last_user_update, you can also see when 
    the table was last accessed (last_user_seek and last_user_scan - do a MAX on 
    them).
    SELECT
        last_user_seek = MAX(last_user_seek),
        last_user_scan = MAX(last_user_scan),
        last_user_lookup = MAX(last_user_lookup),
        last_user_update = MAX(last_user_update)
    FROM
        sys.dm_db_index_usage_stats
    WHERE
        [database_id] = DB_ID()
        -- if you want to leave out system objects, uncomment the next line:
        -- AND OBJECTPROPERTY(object_id, 'IsMsShipped') = 0
    --last modified date
    select name,modify_date from sys.procedures
    order by modify_date desc

  • Displaying fields from a Z Table on CRM UI

    Hello Experts
    I am trying to display fields from a custom table onto a CRM UI form view.
    1. I created a custom GENIL root object & Search object ie. ZCUSTOMER. & ZCUSTSEARCH
    2. Tested this in the GENIL BROWSER to ensure that I could enter update values to the table and retrieve it via the search object.
    3. Created a custom component ZCUSTOMER
    4. Created a view with this component ZCUSTOMER using the wizard -
         Model Name - CUSTINFO
         BOL Entity - ZCUSTOMER
         No links to the custom controller or higher level objects.(as I do not want to tie this to any standard components)
    Type of view - Form view
    7. Created a Context node for the component controller with the same info as I did for the view.
    8. Performed the binding of the view context node with the component controller context node.
    9. Configured 1 field CUST_NAME to be displayed on the view.
    10. Configured the run time repository to display the view.
    Now the issue is..
    When the view gets displayed, the field is displayed with the error "CUST_NAME not bound"
    What am i missing?
    Thanks
    RLX

    Hi Swati,
    Thanks for the feedback. I re-viewed the WD_CREATE_CONTEXT method of the view controller implementation class and I see the following code in there already-
    method WD_CREATE_CONTEXT.
      create the context
        context = cl_bsp_wd_context=>get_instance(
              iv_controller = me
              iv_type = 'ZL_ZCUSTOMER_BSPWDCOMPONEN_CTXT' ).
        typed_context ?= context.
    endmethod.
    Does that look right or do I need to modify it?
    Thanks once again for the help.

    <b>BDCDATA-DYNPRO</b>----
    > this field describes the currently active screen.
    <b>BDCDATA-DYNBEGIN</b>-------> this field describes the default or initial screen.
    <b>BDCDATA-FNAM</b>----

    by using the above table we perfome the mapping logic in BDC for validating and updating the legacy system data.

    Wayne

    Hi,
    In Oracle it is,
    Select column_name from user_tab_cols where table_name  = 'Table_Name';
    Note: Table_Name should be in capital letters
    In MS SQL Server it is,

  • Multiple clob fields in a single table

    Are there any known performance issues associated with having 4 CLOB fields in a single table... the table as such will be relatively small.. like 100 MB... with most rows being << 50k.

    Not really. If you need 4 CLOB columns and it makes sense to have alll the columns in a single table, go for it.

  • Changing the order of fields in an internal table

    Hi all,
    I'm using field symbol as internal table. this table has got a standard database structure.
    I want to make the 3rd column of this internal table as 1st colums keeping rest of the columns as it is.
    Is there any way to do this?
    Thanks,
    Anil.

    Hi
        Instead of directly taking the type as a standard structure , declare the FS  internal table as type of types structure.
    Data: fs_scarr like type_s_scarr.
    FIELD-SYMBOLS <scarr2> TYPE fs_scarr
    In the types put the third column as first one and use into corresponding in select query
    or else
    while displaying the internal table change the order of the columns
    Loop at itab into fs_itab.
    write : col3
    col2
    col4
    endloop.
    Thanks,
