How to find diffrence in columns from two tables

Hello,
I have table TABLE1 and TABLE2 with same columns. One of the columns in both tables is ID
Now there are records in table TABLE1 with ID=1
and in table TABLE 2 with ID=-1
Now I want to find if there are any column differing in values in tables TABLE1 for ID=1(for TABLE1) and TABLE2 for ID = -1 (for TABLE2)
What is the best way to find the diffrence?
Thanks in advance.

Hello Subhash,
Why don't you try NOT EXISTS functionality? Its quite performance effective too.
select * from table1
where NOT EXISTS
(select 1 from table 2
where table1.ID = table2.ID)
UNION
select * from table2
where NOT EXISTS
(select 1 from table 2
where table1.ID = table2.ID)You can go for UNION if required, or else you can use them separately.

    you could try something similar to this, for each table pair that you want to compare:
    SELECT 'TABLE_A has these columns that are not in TABLE_B', DIFF.*
      FROM (
            SELECT  COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_A'
             MINUS
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_B'
          ) DIFF
    UNION
    SELECT 'TABLE_B has these columns that are not in TABLE_A', DIFF.*
      FROM (
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_B'
             MINUS
            SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
              FROM all_tab_columns
             WHERE table_name = 'TABLE_A'
          ) DIFF;that's assuming, column_name, data_type and data_length are all you want to compare on.

  • Selecting columns from two table is slow but same

    I am selecting 27 columns from two tables
    which running for more than 30 minutes. but
    if I select count(*) with the same query
    except the columns it is coming in seconds.
    Where is the error?

    If you post
    1) The table definitions for the underlying tables
    2) The indexes that are on the tables
    3) The two SQL statements you're running
    4) The explain plan for both statements
    we can probably be of some assistance.
    My guess is that the count(*) is able to return much more quickly because the optimizer is able to use a significantly faster query plan that is based on an index which the longer-running query cannot utilize. Without the information I've requested, though, it's hard to do more than speculate.

  • Display columns from two tables without making join

    Hi,
    I need to perform currency conversion in the report.
    For eg:) Whatever the currency in ar_payment_schedules i want to
    convert it to INR equivalent.
    Following is the query to do this.
    select ps.invoice_currency_code Currency_B,
         decode(ps.invoice_currency_code, 'INR',ps.amount_due_original,
                   round(ps.amount_due_original*

         where ps.customer_id          = '111'
         and curr.currency_code      = 'INR'
    When i do this in the Administration tool, the answers modules erroring out saying
    that no joins between ar_payment_schedules and fnd_currencies. But here join is
    not needed becuase fnd_currencies is filtered with INR and will return only
    one row. Without joining two tables how can i get the same results in Answers.
    thanks,
    Prasanna

    If it would return only one row then what is the need for the join (is it just for returning the precision?). Cant you just hard code the precision value instead of getting it from the table? Also you are doing a cartesian join, though the filters would take care of the final output this would result in a bad performance as your data starts scaling out. You need to find a key to join these 2 tables. If you do not have one, then just create a view with the cartesian join alone and then use that in your report.

  • How do I extract matching records from two tables?

    I'm trying to extract client records from our client database to put together a very targeted email campaign. As an example, the result I want is a list of names and email addresses of those clients who have a record in our system, have not had a visit in our clinic in the last year, and live within 200 miles of our clinic. I can capture the first two criteria in one extract, and the second in another. I can then import those as tab delimited data into Numbers. What I then need to do is create a third table that represents ONLY those records that exist in both tables.
    Can someone tell me if this is possible and if so, how to do it?
    I'd be very appreciative of any help, thank you.

    You can create a column that generates a serial marker on the table from which you want to transfer the data, making all the names that also appear on the other table. Not that the formula will mark only exact matches.
    Here's a short example:
    Table 1 on the left, is one of the two tables imported from the tab delimited data files. It has other data, but only the names in column A are used to identify records appearing on both tables.
    Table 2 on the right, contains the names and other data (represented by the email addresses in column B), to be transferred to the third table.
    Column C of this table contains the formula that counts off the rows containing names appearing on both tables. The version below is in C2, and is filled down to the end of the column.
    =IF(COUNTIF(Table 1 :: $B,A2)>0,MAX($C$1:C1)+1,"")
    Note that jane Doe is not counted (or transferred) as her name is recorded differently on the two tables.
    Table 3 is the results table. It contains one formula for each column to be transferred from Table 2 to Table 3.
    A2:   =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $A))
    B2:   =IF((ROW()-1>MAX(Table 2 :: $C)),"",LOOKUP(ROW()-1,Table 2 :: $C,Table 2 :: $B))
    Regards,
    Barry
    EDIT: I was working in Numbers '09 when developing this, and got the following warning when I saved a copy as an iWork '08 document:
    Referencing row or column ranges that include header or footer cells isn't supported. The formula references were updated to exclude header and footer cells.
    The formulas in Table 2::C2 references C1. You may have to ensure that Table 2 does not include a header row.
    B.
    EDIT2: A check on the file in Numbers '08 showed no apparent change to the formula, and editing Jane Doe's name on table 1 resulted in her name being added to Table 3.

  • From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

    From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

    Hi,
    Use NVL or COALESCE:
    NVL (col_a, col_b)
    Returns col_a if col_a is not NULL; otherwise, it returns col_b.
    Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
    For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
    Explain, using specific examples, how you get those results from that data.
    Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

  • How can I tell if signals from two devices are truly synchronised?

    Hi there,
    How does one check that signals from two devices (two separate devices in a single X-series chassis) that should be synchronised actually are?   I am using a PXIe6361 and PXIe4331 on a PXIe-1073, with Labview 2001 SP1 64-bit. All devices are using the Sample Clock from the 4331 device, and an AI Start Trigger, so they should be synchronised.
    I thought that writing the signal data to file and checking the time stamp for each column of data would be the most accurate, but I have been told that timestamps are software created and therefore don't reflect the actual time that the signals were acquired by the hardware.  When I do this, the timestamps vary by up to 150ms which is larger than I expected.
    If I set the x-axis of the waveform graphs (on the GUI) to "Time" then it appears that the first data sample is taken at different times for the two plots (one plot per device).
    If I set the x-axis of the waveform graphs (on the GUI) to "Ignore time stamp" (so that the x-axis just starts from 0 rather than a date-time) then the first data point occurs at "0" for both graphs. However, I'm not sure that this reflects the actual alignment of the signal.
    What is the best way to check if signals collected on different devices in the same chassis are actually synchronised?
    Thanks,
    Claire.

    Hi Lynn,
    Thanks for your help and for sending the demo.
    I understand the concept of how the signals will look if they're not synchronised and your demo shows that nicely. I guess I have been perplexed by someone else telling me that the timestamps in the output file (and following from that I assume timestamps on a waveform graph) do not give an indication of whether signals are synchronised. The reason they gave for this was that the timestamps are manufactured by the software, not the DAQ hardware.  They suggested that I put the setting "ignore waveform timestamps" on my waveform graphs, and then check that both signals come in at the same time (i.e. both start at zero), but I'm not convinced about this. 
    When I use an analog trigger, neither the timestamps in my output file or on the two waveform graphs are synchronised. If I don't use the trigger, then there is far less disparity in the timestamps in the output file. I've attached two output files here, and my VI.
    This is my first attempt to synchronise a voltage module and a strain gauge module on an X-series chassis, so I want to make sure that I'm achieving the best synchronisation that I can, and the difference in behaviour with and without the trigger worries me.
    Thanks,
    Claire.
