  • How to find the special character in a give string/sentance

    Hi All,
    I have one task to complete with in the give time. Since i am not very good in PL/SQL i need your your help.
    Requirement is :
    I have to come up with the SQL or PL/SQL code which should return and find the special or hidden character in the datafiles name in a database. There are nearly 400+ database are present in almost all the flavor of UNIX and i have to check the each and every database.
    As you know , Name of the data file will be like this :
    /u02/instance_name\oradata\datafile_01.dbf So it should avoid these things and find out only the special characters in the datafile name.
    a-z , A-Z , 0-9 and \ Please keep in mind that ...... I will be firing the Oracle script from Oracle 9i client which will access all the database from Oracle 9i to 11g in one short and give me the result.
    Please help me to resolve this issue and let me know if you need more information.

    Hi Frank,
    This is excellent function. Thanks for you responce.
    I want to modify this query in such a way that .... i should get only those datafiles name which are holding special characters. I don't know how to put this in where condition. :( Here's one way:
    SELECT  file_name
    ,       ...     -- other expressions, if you want any
    FROM    dba_data_files
    WHERE   TRANSLATE ( file_name
                      , '?0123456789.ABCDEFGHIJKLMNOPQRSTUVWXYZ\_/abcdefghijklmnopqrstuvwxyz'
                      ) IS NOT NULL Among the other expressions you can put into the SELECT clause (if you want to) is a copy of the TRANSLATE function, as you had in your message. That would highlight exactly which character(s) made the file_name invalid.

  • How to find the level of each child table in a relational model?

    Earthlings,
    I need your help and I know that, 'yes, we can change'. Change this thread to a answered question.
    So: How to find the level of each child table in a relational model?
    I have a relacional database (9.2), all right?!
         O /* This is a child who makes N references to each of the follow N parent tables (here: three), and so on. */
        /↑\ Fks
       O"O O" <-- level 2 for first table (circle)
      /↑\ Fks
    "o"o"o" <-- level 1 for middle table (circle)
       ↑ Fk
      "º"Tips:
    - each circle represents a table;
    - red tables no have foreign key
    - the table in first line of tree, for example, has level 3, but when 3 becomes N? How much is N? This's the question.
    I started thinking about the following:
    First I have to know how to take the children:
    select distinct child.table_name child
      from all_cons_columns father
      join all_cons_columns child
    using (owner, position)
      join (select child.owner,
                   child.constraint_name fk,
                   child.table_name child,
                   child.r_constraint_name pk,
                   father.table_name father
              from all_constraints father, all_constraints child
             where child.r_owner = father.owner
               and child.r_constraint_name = father.constraint_name
               and father.constraint_type in ('P', 'U')
               and child.constraint_type = 'R'
               and child.owner = 'OWNER') aux
    using (owner)
    where child.constraint_name = aux.fk
       and child.table_name = aux.child
       and father.constraint_name = aux.pk
       and father.table_name = aux.father;Thinking...

    Justin,
    Understood.
    Nocycle not work in 9.2 and, even that would work, would not be appropriate.
    With your help, I decided a much simpler way (but there is still a small problem, <font color=red>IN RED</font>):

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

    I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
    If you are young work to Learn, not to earn.
    Solved!
    Go to Solution.

    What about:
    OpenFile ( your file );
    cnt = 0;
    while ((br = ReadLine ( ... )) != -2) {
    if (br == -1) {
    // I/O error: handle it!
    break;
    cnt++;
    CloseFile ( ... );
    There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
    After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
    Proud to use LW/CVI from 3.1 on.

  • How to find the number of entries in a master data table

    Hi Experts,
    I am trying to find the entries in 0CUSTOMER master data.
    BW>LISTCUBE>Data target: 0CUSTOMER and selected the fields that I need.
    I would like to know how to find the "number of entrees". I tried to run the SUM for a count field, but it is taking forever as there are huge number of records .

    Hi Dev,
    Go to the change/display mode of the info object (0CUSTOMER) in your case. Go to the Master data/Text tab. Here you will find the master data tables according to your settings (P orQ or X or Y). Double click on the table name and it will take you to the SE11 display. From there, you can check the number of records as you do in any transparent table.
    Hope this helps.

  • How to find the number of links in a website

    hi every body
    can any one clear my doubt
    my doubt is that
    in a website how to find the number of links the hole website contains
    is there any navigation tool to find that
    plz help me yar
    i am waiting for the reply

    If you're talking about commercial sites (sites you don't have the source code for) I'm not sure.
    If you want to count the links in site that you have the source code for, it should be relatively easy to write a Java application to do it. All you really need to do is have a list of the files you want to count links in, read each file line by line and check for the existance of the <a> tag in each line. Anywhere their is an <a> tag there is a link.
    Hope this helps.

    How To Ask Questions The Smart Way
    Eric Steven Raymond
    Rick Moen
    Write in clear, grammatical, correctly-spelled language
    We've found by experience that people who are careless and sloppy writers are usually also careless and sloppy at thinking and coding (often enough to bet on, anyway). Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
    So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal ? in fact, hacker culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
    Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "discrete" with "discreet". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All-smalls is only slightly less annoying, as it's difficult to read. Alan Cox can get away with it, but you can't.)
    More generally, if you write like a semi-literate b o o b you will very likely be ignored. So don't use instant-messaging shortcuts. Spelling "you" as "u" makes you look like a semi-literate b o o b to save two entire keystrokes.

  • How to find the number of fetched lines from select statement

    Hi Experts,
    Can you tell me how to find the number of fetched lines from select statements..
    and one more thing is can you tell me how to check the written select statement or written statement is correct or not????
    Thanks in advance
    santosh

    Hi,
    Look for the system field SY_TABIX. That will contain the number of records which have been put into an internal table through a select statement.
    For ex:
    data: itab type mara occurs 0 with header line.
    Select * from mara into table itab.
    Write: Sy-tabix.
    This will give you the number of entries that has been selected.
    I am not sure what you mean by the second question. If you can let me know what you need then we might have a solution.
    Hope this helps,

  • How to find the number of occurance of a string in text field of Infopath form?

    Hi All,
    In Infopath text field, How to find the number of occurrence of a particular string in that field?
    Thanks in advance!

    You can check to see if it contains a string once by using the contains function, but there isn't a very clean way to do what you want. If you wanted to guess at the maximum number of occurrences, then you could:
    Box A has your initial. Set Box B to do a concat of string-before and string-after of Box A where it copies Box A minus the string we're looking for. Then we have Box C that does the same thing to Box B. Repeat as many times as you see necessary.
    Example:
    String: "1"
    Box A - "123451234512345"
    Box B - "23451234512345"
    Box C - "2345234512345"
    Box D - "234523452345"
    etc.
    We then have a field that has nested ifs looking backwards from Z -> A looking for a non-blank. Based on that, we return the number of occurrences. Again, this isn't clean, but it will work if you think there's a predefinable maximum.

  • How to find the number of users  connected to database from OS level(Linux)

    Thank you.
    Regards,

    Excellent.
    Tested, works as long as you set the ORACLE_SID first ( to change databases )
    ps -ef | grep $ORACLE_SID | grep "LOCAL=NO" | awk '{print $2}' | wc -l
    Thanks!
    select OSUSER
        from V$SESSION
    where AUDSID = SYS_CONTEXT('userenv','sessionid')
        and rownum=1;Best Regards

  • How to find the number of ODBC connections to Oracle Database

    Hi All,
    How to find the number of ODBC connections and all connections to the Database in last week. Are there any views to get this information?
    Thanks in advance,
    Mahi

    What Ed said is true that Oracle doesn't note which type of protocol is connecting to the database, however, you can see which program is accessing the database.
    For example: if you already know of a user using ODBC, you can verify as:
    select username, osuser, terminal, program from v$session where username = 'SCOTT'
    USERNAME                 OSUSER          TERMINAL   PROGRAM
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    2 rows selected.Assuming that you can confirm the progam noted in the above (example) is the one using ODBC, then you can change the query such as:
    SQL> select username, osuser, terminal, program from v$session where program = 'w3wp.exe';
    USERNAME                 OSUSER          TERMINAL   PROGRAM
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    SCOTT                    IUSR_SRV231     SRV231     w3wp.exe
    2 rows selected.Just for kicks, I checked our listener.log file, but there was no reference of odbc in it either.
    Hope this helps...
