How to find the volume of data

Hello

We want to know the volume of the data inserted in database schema per day.
Is there a way that we can find this information?

We have so many tables in our database. If the row count is not an effective calculation.
And there are so many blobs in the table. Each line is different from the ranks.

Database version: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi

Thank you
Ravi

It is already instrumented by Oracle: segment statistics.

  • How to find the number of data items in a file written with the ArryToFile function?

    I wrote a table of number in 2 groups of columns in a file using LabWindows/CVI ArrayToFile... Now, if I want to read the file with the FileToArray function so how do I know the number of items in the file. during the time of writing, I know how many elements array to write. But assume that I want the file to be read at a later time, then how to find the number of items in the file, so that I can read the exact number and present it. Thank you all

    Hello

    I start with the second question:

    bytes_read = ReadLine (file_handle, line_buffer, maximum_bytes);

    the second argument is the buffer to store the characters read, so it's an array of characters; It must be large enough to hold maximum_bytes the value NULL, if char [maximum_butes + 1]

    So, obviously the number of lines in your text tiles can be determined in a loop:

    Open the file

    lines = 0;

    While (ReadLine () > 0)

    {

    lines ++;

    }

    Close the file

  • How to find the broken blob data

    Hello

    I am using oracle 10G express edition and Oracle Apex 4.1 front-end, have created a table with structure below.

    > > CREATE TABLE 'HR_EMPLOYEE_DETAILS '.
    > > ('ID' NUMBER ENABLE NOT NULL,)
    > > 'HR_ID' ENABLE NUMBER NOT NULL,
    > > 'PHOTO_BLOB' BLOB,
    > > "MIME_TYPE" VARCHAR2 (64)
    (> >)


    I wrote a program sqlloader to load all the images in the table above, there are a few rows of data where the photos have not get uploaded, which shows the user but photo id is empty, how to identify such lines. Please suggest me

    Thank you
    Sudhir

    Your photo_blob column can have NULL values, in this case you can find them with something like:

    select id
      from hr_employee_details
     where photo_blob is null
    

    Or the photo_blob was filled with a LOB Locator is valid but contains no data. These cases can be found with something like:

    select id
      from hr_employee_details
     where dbms_lob.getlength(photo_blob) = 0
    

    Or you could have a case where some of the bytes actually enter the blob, but not all resulting in an invalid image. Who is going to be more difficult, try so the other two cases first ;-)
