Insert value into mysql db...

Hi guys,
i'm a new user of jsf and i have a problem...
I've developed my first JSF application that load as input an input a file and store it with a fixed format into an array of byte.
Now i have to put this array of byte into a blob field of a mysql database.
How can i do?
Do you know some demo application on internet that i can study...?Or material to see?
Thanks very much

[This page|http://java.sun.com/developer/technicalArticles/Intl/HTTPCharset/] has a good explanation of where the issues might be.
The thing with character encodings is that you have to get it right at every step. If you miss one of them, then the whole thing blows apart.
From the minimal info you have here, I would take a look at the request.setCharacterEncoding() methd.
cheers,

    empl_name ( Foreign key)
    contact_no (primary key)
    my senario is , i need insert values into both parent and child table in one save option.
    and both the tables will be in one jsf page.
    is this possible to do?

    hi,

    let me explain my question clearly.
    1. i have two records
    *1. emp_names*
    attributes of this table is 1.emplid
    2.emp_name.
    emplid is a primary key.
    2. emp_contact
    attributes of this table is 1.emplid
    2. contact_no
    In this table emplid is forigen key from emp_name table
    contact_no is primary key.
    and my senerio is,
    for one emplid there are many contact no.
    in database diagram i have created these two entities. and from that i have generated two views objects.
    now in jsf page ,
    i shd have all fields from both the records.
    wn ever i click on add button , i shd be able to insert one complete row of data to both the tables.
    means,
    emplid
    empl_name
    contact_no.
    and if i click on commit button data shd be insert in both the tables.
    so how to achive this?

  • Oracle 10g - Insert value into a self-created table in stored proc

    Hi all,
    Say I'm creating a table using the following logic,
    pc_create_table := 'create global temporary table revs(var1 number(5,0), ..., ...,) on commit preserve rows';
    execute immediate pc_create_table;
    When I'm attempting to insert value into this table (v_var1 is a pre-defined variable),
    pc_insert_value := 'insert into revs(var1, ..., ...,) values (v_var1, ...)'
    execute immediate pc_insert_value;
    I got the following error: "ORA-00984: column not allowed here"
    Any advise on this issue? Thanks a lot

    Its not designed that way, is not a good practice and is strictly not recommended. You can read <a href ="https://forums.oracle.com/forums/profile.jspa?userID=287238">Billy Verreynne's</a> take on this :
    {message:id=10040770}
    To my suprise it's saying the table or view does not exist. According to my logic, the table "revs" created by executing pc_create_table, however it's NOT explicitly declared in other parts of this script, is this where the problem is?The Problem is, SQLs fired using Execute Immediate are evaluated, compiled, parsed and executed at run time. So when you compile procedure pc_create_table, table revs is still not created. Hence you get error when you try inserting rows in it.
    Any advises are appreciated.Get the table created by your DBA, and use insert statement without execute immediate in your procedure.

  • PHP/MySQL: Get value from one field, subtract 2, multiply by 20,   and insert value into another column on form submit

    Hello all,
    I'm pulling my hair out--thank you for any help you can give
    me.
    I have a form that a person fills out that has a field that
    asks "How
    many visitors including you" and I'd like them to type in a
    number, and
    on submit of the form, have that value -2 multiplied by 20
    and inserted
    into a "total cost" column.
    I'm using the standard DW server behaviors and I've searched
    the
    internet. How do I perform basic math on that value and
    insert it into
    the database?
    If you have any pointers, that would be great.
    Thank you!
    -John

    To pass the details to a thank you page, you would need to
    store the
    information in $_SESSION variables. You could amend the
    earlier script
    like this:
    <?php
    session_start();
    if (isset($_POST['visitors'])) {
    if ($_POST['visitors'] < 3) {
    $num = 0;
    } else {
    $num = $_POST['visitors'] - 2;
    $_POST['total_cost'] = $num * 20;
    $_SESSION['total_cost'] = $_POST['total_cost'];
    $_SESSION['first_name'] = $_POST['first_name'];
    $_SESSION['last_name'] = $_POST['last_name'];
    ?>
    In the thank you page, put the following at the top of the
    page:
    <?php session_start(); ?>
    It must go before anything is output to the browser, so put
    it above the
    DOCTYPE declaration, and make sure there's no space before
    it.
    You can then use the $_SESSION variables in the thank you
    page.
    At the end of the page, add this to clear up the session
    variables:
    <?php
    $_SESSION = array();
    destroy_session();
    ?>

  • Problem in inserting data into MySQL table

    Hi All,
    I have a table with just two fields FIRSTNAME and SECONDNAME in MySQL. I am accepting the First Name and Second Name in two text fields and then trying to insert them into the MySQL table. I have set the concurrency of the rowset to CONCUR_UPDATABLE and am using the code clip for Database row insert with the appropriate changes. When I run the application it doesnt give me any errors but the data is also not inserted in the table. Can someone pls help me out.
    Loneliness wins the race :-)

    This is my problem when inserting single row. What does it means ?
    MusicInsert: com.mysql.jdbc.NotUpdatable: Result Set not updatable.This result set must come from a statement that was created with a result set type of ResultSet.CONCUR_UPDATABLE, the query must select only one table, and must select all primary keys from that table. See the JDBC 2.1 API Specification, section 5.6 for more details

  • Need to insert values into a table from a XML file

    Hi,
    I'm an Oracle 9i/10g DBA with quite a few years experience, but I'm new to XML and dealing with it in database terms. I've been given a project that entails pulling XML values out of a file (or 100's of them) and storing them in the database so that they are searchable by end-users. The project is classified as secret so I'm unable to upload the specific XML or any info relating to the structire of the XML or the table I will use to insert the values into - sorry!! So, I've created an XML file with a similar structure to help people understand my predicament.
    The end-users only need to search on a subset of the total amount of columns from the table I'll insert data into, although the XML file has a lot more, so I dont need to store the other values - but I will need to store the name of the XML file (or a pointer to it so I know what XML file a particular set of values belong to) in another column of the table along with its associated values.
    I've been using the XMLTABLE function with some degree of success, although I had better succes using the XMLSEQUENCE function. However, I found out this is deprecated in 10g and replaced with XMLTABLE, so I guess it's better if I use this in case we ever need to upgrade to 11g.
    The main problem I've been having is that some elements in the XML files have multiple values for the one record when all the other records are the same. In terms of storing this in the database, I guess it would mean inserting multiple rows in the table for each element where the value differs. Here is a dumbed down XML file similar to what I've got along with the other SQL I've used:
    +<?xml version="1.0" encoding="UTF-8"?>+

    CREATE TABLE xmltest OF XMLTYPE;
    INSERT INTO xmltest
    VALUES(xmltype(bfilename('XML_DIR', 'test.xml'), nls_charset_id('AL32UTF8')));
    Consequently, I need to...
    1) Retrieve the results from the XML file for all 3 warehouses where multiple values for the same sub-element are shown as 2 rowsthe result set. (I am guessing there will be 4 rows returned as warehouse sub-2 has 2 different elements for <WarehouseName>.
    2) Build a case statement into the query so that regardless of the sub-element name (i.e State or County), it is returned into the 1 column, for instance County.
    So, if I run a query similar to the following...
    select y.WarehouseId, y.Town, y.County, y.Area
    from xmltest x, xmltable('/House/Warehouse' .......
    I would like to get results back like this...
    ID Town County Area
    1 Southlake Texas 25000
    2 Poole Dorset 40000
    2 Solihull West Midlands 40000
    3 Fleet hampshire 10000
    Sorry for the non-formatting but I hope this all makessense to someone out there with what I'm trying to do.
    I appreciate any help whatsoever because, as i said before, I'm totally new to XML and trying to read the vast amount of information there is out there on XML is all a bit daunting.
    Many thanks in advance,
    Shaun.

    select * from table(XFileHandler.getRows('XML_DIR', 'XFileHandler_test.xml'));I get the error: ORA-00600: internal error code, arguments: [17285], [0x5CFE8DC8], [4], [0x45ABE1C8], [], [], [], []
    I had a look in the dump file for anything obvious, but nothing really stands out. Is there anything obvious in my code that I'm missing or something else which you may think could be causing this error, e.g in the regular expression regexp_substr?
    Many thanks,

  • Insert value into a column based on value of another column

    Hi,
    I am trying to insert a value into a record based on a column in
    the record, using a trigger. The complication arises because
    the new value is selected from the same table. For example:
    SELECT COL1, COL2, COL3, COL4 from TABLE1
    I want to set COL2 and COL3 based on the value of COL4. And to
    get the value of COL2 and COL3, I will go back to TABLE1 and set
    the condition to TABLE1.COL1 = :NEW.COL4
    I cannot seem to execute the trigger as I get the message "ORA-
    04091: table SYSTEM.TABLE1 is mutating, trigger/function may not
    see it" everytime.
    Is this the correct way to achieve what I wanted? Or is there
    another way?
    Appreciate your feedback. Thank you in advance.

    Appreciate your feedback. Thank you in advance. I'm not sure what you mean when you insert a value into a
    record, but if you are setting a value in a column of the same
    record using a trigger, then it's easy.
    :new.COL2 := ....:new.COL4...
    :new.COL3 := ....:new.COL4...
    The trigger must be 'INSERT or UPDATE' and 'FOR EACH RECORD'.
    If you are setting a different record in the same table, the
    solution is much more difficult.

  • SQL Server 2012 Management Studio: Creating a Database and a dbo Table. Inserting VALUES into the table. How to insert 8 Values for future use in XQuery?

    Hi all,
    In my SQL Server 2012 Management Studio (SSMS2012), I tried to create a Database (MacLochainnsDB) and a dbo Table (marvel). then I wanted insert 8 VALUES into the Table by using the following code:
    USE master
    IF EXISTS
    (SELECT 1
    FROM sys.databases
    WHERE name = 'MacLochlainnsDB')
    DROP DATABASE MacLochlainnsDB
    GO
    CREATE DATABASE MacLochlainnsDB
    GO
    CREATE TABLE [dbo].[marvel] (
    [avenger_name] [char] (30) NULL)
    INSERT INTO marvel
    (avenger_name)
    VALUES
    ('Hulk', 1),
    ('Iron Man', 2),
    ('Black Widow', 3),
    ('Thor', 4),
    ('Captain America', 5),
    ('Hawkeye', 6),
    ('Winter Soldier', 7),
    ('Iron Patriot', 8)
    I got the following error Message:
    Msg 110, Level 15, State 1, Line 5
    There are fewer columns in the INSERT statement than values specified in the VALUES clause. The number of values in the VALUES clause must match the number of columns specified in the INSERT statement.
    How can I correct this problem?
    Please kindly help and advise.
    Thanks in advance,
    Scott Chang
    P. S.
    The reason I tried to create the Database, dbo Table, and then to insert the VALUES is to learn the following thing:
    You can query the entire node tree with the following xquery statement because it looks for the occurrence of any node with the /* search string:
    DECLARE @x xml;
    SET @x = N'<marvel>
    <avenger_name>Captain America</avenger_name>
    </marvel>';
    SELECT @x.query('/*');
    You can query the avenger_name elements from the marvel_xml table with the following syntax:
    SELECT xml_table.query('/marvel/avenger_name')
    FROM marvel_xml;
    It returns the following set of avenger_name elements:
    <avenger_name>Hulk</avenger_name>
    <avenger_name>Iron Man</avenger_name>
    <avenger_name>Black Widow</avenger_name>
    <avenger_name>Thor</avenger_name>
    <avenger_name>Captain America</avenger_name>
    <avenger_name>Hawkeye</avenger_name>
    <avenger_name>Winter Soldier</avenger_name>
    <avenger_name>Iron Patriot</avenger_name>
    You can query the fourth avenger_name element from the marvel_xml table with the following xquery statement:
    SELECT xml_table.query('/marvel[4]/avenger_name')
    FROM marvel_xml;
    It returns the following avenger_name element:
    <avenger_name>Thor</avenger_name>

    Hi Scott,
    The master database records all the system-level information for a SQL Server system, so best practise would be not to create any user-defined
    object within it.
    To change your default database(master by default) of your login to another, follow the next steps so that next time when connected you don't have to use "USE dbname" to switch database.
    Open SQL Server Management Studio
    --> Go to Object explorer(the left panel by default layout)
    --> Extend "Security"
    --> Extend "Logins"
    --> Right click on your login, click "propertites"
    --> Choose the "Default database" at the bottom of the pop-up window.
    --or simply by T-SQL
    Exec sp_defaultdb @loginame='yourLogin', @defdb='youDB'
    Regarding your question, you can reference the below.
    SELECT * FROM master.sys.all_objects where name ='Marvel'
    --OR
    SELECT OBJECT_ID('master.dbo.Marvel') --if non empty result returns, the object exists
    --usually the OBJECT_ID is used if a if statement as below
    IF OBJECT_ID('master.dbo.Marvel') IS NOT NULL
    PRINT ('TABLE EXISTS') --Or some other logic
    What is the sys.all_objects? See
    here.
    If you have any question, feel free to let me know.

  • How to parse XML Column and insert values into a table

    Hello,
    I am working on a simple project to demonstrate how to load and extract XML using SQL, I have already made a table that contains a column of XMLTYPE and loaded an XML file into it (code below)
    create or replace directory XMLSRC as 'C:\XMLSRC';
    drop table Inventory;
    create table Inventory(Inv XMLTYPE);
    INSERT INTO Inventory VALUES (XMLTYPE(bfilename('XMLSRC', 'Inventory.xml'),nls_charset_id('AL32UTF')));
    select * from Inventory;
    I now however need to get the XML data back out of that and loaded into a new table. Troubleshooting guides I have read online seem to only be dealing with parsing an external XML document and loading it into a table, and not what I need to do which is parse a column of XML data and load that into a table. The project trivial with simple tables containing only 3 columns.
    The table that needs to be loaded is as follows:
    create table InventoryOut(PartNumber Number(10), QTY Number(10), WhLocation varchar2(500));
    The XML document is as follows:
    <?xml version="1.0" encoding="UTF-8"?>
    <dataroot xmlns:od="urn:schemas-microsoft-com:officedata" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Inventory.xsd" generated="2012-04-09T17:36:30">
    <Inventory>
    <PartNumber>101</PartNumber>
    <QTY>12</QTY>
    <WhLocation>WA</WhLocation>
    </Inventory>
    </dataroot>
    Thank you for any help you can offer.

    First of all, thank you for your help!! Still stunned that you actually took the time to write out an eample using my tables/names/etc. Thank you!!
    Attached is the code, there seems to be an issue with referencing the other table, Inventory.Inv, I checked and that table and the Inv column are showing up in the database so I am not sure why it is having issues locating them, take a look at the code I wrote as well as the output (*I included the real version number for you this time :)
    EDIT: In your code right here:
    select xt.*
    3 from Inventory inve,
    4 XMLTable('/dataroot/Inventory'
    5 PASSING inve.Inv
    I think is where I am messing it up, perhaps not understanding fully what is going on, as you write "Inventory inve" and "inve.Inv" ---- Is inve a keyword that I am just not familiar with? I think this is where the issues lies in my code.
    END EDIT
    EDIT2: Well that looks like it was it, changed that to how you have it and it now works!!! Could you please explain what that few lines is doing, and what the xt.* and inve are doing? Thanks again!!!

    If this helps here is the code and output for the creation of the Inventory table itself:
    create or replace directory XMLSRC as 'C:\XMLSRC';
    drop table Inventory;
    create table Inventory(Inv XMLTYPE);
    INSERT INTO Inventory VALUES (XMLTYPE(bfilename('XMLSRC', 'Inventory.xml'),nls_charset_id('AL32UTF')));
    select * from Inventory;
    directory XMLSRC created.
    table INVENTORY dropped.
    table INVENTORY created.
    1 rows inserted.

  • Trying to insert values into a table inserts the wrong values

    Hi, I'm sure this is quite simple but I don't know why it is happened (Spent about 2 hours debugging my program only to find the error is actually in the SQL insert statement not working properly hehe)
    I have a simple Payment table with the following columns:
    int - ID (primary key)
    int - Amount
    int - Paid
    varchar - Notes
    I try to place a new record into the table as follows:
    insert into payment values (1010,50,1,'Hello')
    but the ID i choose is not added to the record, rather the database assigns a ID instead automatically (it seems to add 1 to the last ID)
    On further inspection this happens for another of my tables too, however for another table, this does not happen and I can assign an ID as I would like.
    When creating my tables I thought I set them all up the same, however I guess not
    Does anyone know the problem?
    Thanks

    Hi,
    Are you are using this INSERT statement in any form??? if so, please check your pre-insert trigger.
    If not, then you may verify it by inserting it through iSQLPlus. If it doesn't insert your data, then check the database triggers associated with INSERT for your table.
