How to find a matching column in tables

Hello,
I have a need to find out a common column in all tables in database.
For e.g. There is a database column called machine_name
I need to know how many tables in database have this column name. Is there a straightforward way to achieve this without substantial coding?
This is on 9i EE
Thanks,
R

Tubby,
Since op asked for:
I have a need to find out a common column in all tables in database_*.it should be DBA_TAB_COLS. But what is more important, ALL_TAB_COLS holds not just table but also view and materialized view columns, so in general it should be:
select  c.owner,
        c.table_name
  from  dba_tab_cols c,
        dba_objects o
  where o.owner = c.owner
    and o.object_name = c.table_name
    and o.object_type = 'TABLE'
    and c.column_name = 'MACHINE_NAME'

  • How to find latest entry in the table according to time

    how to find latest entry in the table according to the time
    is there any function module to do so

    Edited by: Jan Stallkamp on Aug 25, 2008 4:39 PM

    Hi,
    If you want to read the entry from an internal table,
    sort the internal table in the descending order by the time and
    delete adjacent duplicates by comparing the fields other than time and the internal table will have the latest record.
    Suggestion: instead of only time try to have one more field called date with the time combination

    Hi Solomon,
    so I have to identify partition & index are created or not,
    also I have check the status of index ( both global and local)So what's the problem? Table/index partition is an object, so you can query DBA_OBJECTS:
    SELECT  SUBOBJECT_NAME,
            CREATED
      FROM  DBA_OBJECTS
      WHERE OWNER = partitioned-table-owner
        AND OBJECT_NAME = partitioned-table-name
        AND CREATED >= TRUNC(SYSDATE)
    /This will give you partitions created today. So if you run this right after your job (I hope your job doen't run too close to midnight), you'll get table partition name your job created. Same logic can be applied to indexes.

    Hi,
    MBEWH is actually the history table of MBEW. It will record all the changes. As I have told you earlier if you have deleted the record dirctly from the table then it will not come even in the table MBEWH
    That means no changes have been made.

    How to find which datasource is using table JCDS?

    Hi,
    Please find the below link and identify whether will it meet your requirement or not ... If it meets your requirement then I can provide you more documents related to the same which we have in our project.   We were using the same for Plant Maintanance project...
    For this report the required information is gathering from the different data sources from the ECC system. This report requires object status functional location attributes, Equipment attributes and some specific information apart from normal transaction data for an order.
    u2022     Main feeding data sources for this report are 2LIS_17_ORDER and 2LIS_18_ORDER.
    u2022     Requires the object status data (system status, number object status and un-number system status) is feeding from different DSO where the status data is staging with different data flow.
    u2022     Requires the Order planned end date which is dependent on the operation  planned completion date. so we are feeding this field from Operationu2019s DSO where the planned date is staging with different data flow.
    u2022     Required characteristic data and attributes of the Functional location  is getting from the master data .The 0FUNCT_LOC is updating by master data data sources
    u2022     Required standard class  of the functional location is updating from other DSO where the  classification  data is staging with the help of different data flow.
    2LIS_17_ORDER and 2LIS_18_ORDER Data flow Details : No enhancement was done for these data sources .
    Status Data Flow Details:
    The status data is staged because ,this dat is required for the reports based on the Orders, Operations , Notifications, Functional Location and Equipment.
    To load suitable data to different DSOs from the Status DSO we maintain the Filters for status profile and status at DTP level.
    Required status change dates  are deriving based on changed on date ,system status while loading from status DSO to Order DSO.
    The system status ,Number object status and un- numberd object status are feeding from status DSO only.The status DSO is updating by u20180TE_OBJ_STATUS_HISTu2019.This Is based on the tables JCDS,JSTO and T000.
    JCDS     MANDT     =     JSTO     MANDT
    JCDS     OBJNR          =     JSTO     OBJNR
    T000     MANDT     =     JCDS     MANDT
    This DS has enhanced for the below  two fields
    1.     Order Number
    2.     Operation/Activity Number
    The Logic to populate the above two fileds is as below.

  • How to find out the columns which has 16 digit credit card number

    Hi All,
    I have a requirement where in i need to find out the columns which has 16 digit credit number in it and create a report with owner, table name and column name.
    The issue is that the credit card number can be entered in any columns of any table of any schema. For example the credit card number can be entered in any description field(eg: The number is 4001412134642881), in that case i need to filter only the numbers and do the LUHN check to validate the credit card number.
    Please provide me a suggestion on how to scanl the values of all the columns to know the column which has credit card number.
    Regards,
    Raj.

    Tell me this - how the hell do you have a database with credit card number data and NOT know which columns of which tables contain credit card numbers? (and how on earth is this data NOT encrypted!?)
    How is what you want to do, NOT a fishing expedition to hack a database that may or may not be storing credit card details?
    And do you honestly think that we should simply trust that once you have extracted these numbers, performed a Luhn algorithm to verify these as credit card numbers, you are not going to fraudulently use these credit card numbers!?
    I have marked your posting as an attempt to hack an Oracle database for fraudulent use of credit card data. I hope that your OTN account is terminated soon and trust that your too much of a coding idiot to actually succeed in this endevour.
