Should be a simple question: How do I search for properties of the BLOB columns?

Hi people,

It's just out of my mind. How can I get a BLOB properties using the query?

I have a table with a BLOB column where documents are stored. I would like to get information on the size of each BLOB content.
SQL> desc document
Name              Type          Nullable Default Comments 
----------------- ------------- -------- ------- -------- 
OBJECT_ID         NUMBER                                  
TIMESTAMP         DATE                   sysdate          
TITLE             VARCHAR2(200) Y                         
DOCUMENT_TYPE     NUMBER        Y                         
DOCUMENT_FILENAME VARCHAR2(200) Y                         
DOCUMENT_TEXT     BLOB          Y   
How to find the DOCUMENT_TEXT properties (size)?

Thank you
Tomas

  • XML question: How do I search for children without grandchildren

    With an XML document:

    var xml =

    < root >

    < name L1 = "First" >

    < garbage / >

    < / L1 >

    < name L1 = "Second" >

    < garbage / >

    < / L1 >

    < / root >

    I need a XMLList tags < L1 > without their children, then the output should be:

    < name L1 = "First" >

    < name L2 = "Second" >

    Can someone help me with the syntaxt actionscript to accomplish this XML query? I could not find an example that does not return the children of the < L1 > tags as well.

    Thank you

    David

    Well, if you need exact release, you could use this line:

    trace (xml.toXMLString (match) (/<\s*L1.*?>/g) .join ('\n'));

    This approach much faster that doing redundant xmlfiltering + removal of garbage, hope this helps

    Simple question - how to make an onchange event occur in a list to start a process of selection?
    Thank you

    (1) with the ApEx selection about to submit list.
    You create a PL/SQL process after Submit. -> Request for conditional Type = Expression1. -> Expression1 is the name of your selection list. Treat the Source - > procedure you like. For example based on your select list value you add rows in different tables.

    Simple question-how to call a stored procedure or function of apex?
    Thanks advance.
    Doug

    Hi Doug,.
    You can call a procedure or function of apex. It depends on what you want to do with the function or procedure. If you want to retrieve table data in a specific area, you can try something like this-

    The following statement creates the function get_bal on the oe.orders of sample table (PL/SQL is in italics):

    CREATE FUNCTION get_bal (acc_no in NUMBER)
    RETURN NUMBER
    IS acc_bal NUMBER (11.2);
    BEGIN
    SELECT order_total
    IN acc_bal
    Orders
    WHERE customer_id = acc_no;
    Return (acc_bal);
    END;
    /

    The function created in the previous example can be used in a SQL statement. For example:

    SELECT get_bal (165) FROM DUAL;

    GET_BAL (165)
    ------------

    hope this will help,

I got a dialog box indicating that I had to run Java SE runtime (or something to that effect), when I approved it, then try opening cs5.5 Indesign, the program closed unexpectedly at startup. If I uninstall program & reinstall, my documents will be free, or are they toast? Help!

  • How can I search for hexadecimal number of 32-bit in .csv file

    Hello

    How can I search for 32-bit in .csv file usinf labview 8.6.1 hexadecimal number

    Mathan,

    This post was not really a solution.  He just ordered Sandy to post in the appropriate forum, which we now know is LabVIEW 8.6.1 LV.

    Sandy,

    You want to read the text file, then use the search/Split String function to find the matching characters that make up your hexagonal pattern.

    What you ask is a little strange wordly since .csv files are text files, and you ask a "32-bit hexadecimal number.  Can you give an example of what you are looking for?  My response assumes you have a 8 string that consists of the characters 0-9, A - F for catch the 4 bytes.  Maybe you are dealing with just 4 bytes that present themselves as ASCII characters in a text file.  In which case you wouldn't have one. CSV file.

    If the response of research/Split String is not useful to you, you will need to provide details about what you are looking for and also an example of your. CSV file.
