Serialization Objects in column of row in MySQL

Hi :)
I have class with different methods, each of this methods make large operation in database (Hibernate3 + MySQL).
I consider situation when my application may crush, and in proccess of recovering I recover objects-parameters for my different methods.
I want to use simple Java serialization object (ObjectInputStream and ObjectOutputStream) and save this bytes in column of row in MySQL, but
in future I'm afraid that fields of parameter-objects of my methods changed (will be add new fields, deleted fields), and I can't deserialize my parameter-objects from MySQL. I know one decision - serialization objects in XML and save XML in DB, but may be somebody offers other variants of saving my object-parameters more quickly than XML.
Thanks all :) New member of Sun Java Forum, Alexander Stepanov.

Calculation Field to be mapped to different data object's column name in Oracle BAM 12c

Hi,
I am having a challenge to enable drill down to 2nd level report by passing calculation field as parameter.
As an alternative, I am thinking to point calculation field to another data object’s column name and generate report so that I would be able to pass that as parameter to drilling report view.
Is there any way to map calculation field to different Data object’s column name? Thanks in advance.

1. Yes, you can.

1 row created.1.1 and 1.2 and 2. You can choose UTF as your default character set. It allows the user of non-English characters in VARCHAR columns in your whole database. It is not per tablespace.

Inserting non-serializable objects

Is there any way to insert non-serializable objects into a database? (Or to convert them to bytes?)

Is there any way to insert non-serializable objectsinto a database?
A joke right?No, it's not a joke. It would be a pretty bad one if it were.
Yes, there is a way. Create a table that corresponds
to the object where each attribute in the object
corresponds to field in the object. Add a unique key
if one doesn't exist.I wish it were that simple. I don't have access to those attributes...
>
To create an object insert a row into the table. To
load the object use the unique key to query for the
row. To 'delete' the object delete the row from the
table.BTW, the object in question is the java.awt.geom.Area object (http://java.sun.com/j2se/1.3/docs/api/java/awt/geom/Area.html ).
The only way I can think of to insert an object that doesn't map to a SQL type is to convert it to bytes through serialization, and insert it as RAW data.
I've extended Area to add a name and made my class serializable. However, since Area is not serializable, the only data I can retrieve after deserializing is the name I added (from my understanding of serialization, I have to save Area's data myself, but can't since I don't have access to it, so the deserialization process calls the Area() constructor which initializes the object to empty).

How to fetch last inserted row in MySQL

I am trying to get the last inserted row in MySql..but not able to fetch it.

any help is appreciated .
the usage of lastinsert() method is also not successful

Hello
Given you have a date column, you can use it to determine the latest row. However, there is still a chance that two rows were inserted at exactly the same time in which case you will need something in addition to your date column to decide which is the latest...
The first option uses a sub query and the second uses analytics, as does the 3rd - however with the 3rd, if 2 rows have exactly the same date and time, it will pick one at random unless you include another column in the order by to determine the latest...
select
FROM
    your_table
WHERE
    your_date_column = (SELECT MAX(your_date_column) from your_table)
SELECT
FROM
        select
            a.*,
            MAX(your_date_column) OVER() max_date_column
        FROM
            your_table a
WHERE
    your_date_column = max_date_column
SELECT
FROM
        select
            a.*,

Make sure the photos are "within" celsl and they should sort along with the rest of your data. One way to do this: select a photo that you have in the sheet that is not sorting with the data, command-x to cut, click once in a cell, and paste. Then adjust the row height and width to make the images larger.

Hi,
have a look at the Formatter class:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.html
There are also convenience methods e.g. in String:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html#format(java.lang.String,%20java.lang.Object...)
or - if you use System.out for example -

SWAP COLUMNS AND ROW IN AN INTERNAL TABLE to display in ALV

Hi ,
I want to swap all the rows in an internal table with the column of the internal table to display it horizontally in ALV grid.
e.g
1     2   3 (field names)
A    P   X
B    Q   Y
C    R    Z
should look like :
D       A   B     C
E      P   Q    R
F       X    Y    Z
Where D , E, F in first column is already apended in new table.
Or else is there a way to rotate the ALV grid so that it can display rows as columns & columns as rows.

How to enter a data into the specified column and row in a created table

Hi,
I want to enter some data to specified column and row in a already created table. Please let me know how to do this.
Regards
Shivakumar Singh

A table is just a 2D array of strings. Keep it in a shift register and use "replace array element" to modify the desired entry programmatically.
If you want to modify it manually and directly from the front panel, make it into a control and type directly into the desired element. (In this case your program would need to write to it using a local variable).
Atttached is a simple example in LabVIEW 7.0 that shows both possibilities.

Filling in values based on the column and row headers

I have a question that seems simple, but I can't figure out how to do it and I've searched all over the forum to no avail.
I have one column that is width increasing by 3 in. increments (column A)
I have one row that is height increasing by 3 in. increments (row B)
I have one cell that is price (cell A1)
I have a formula to calculate price per sq. ft.: =CEILING(A3B2/144,1)A1. This gives me the whole sq. ft. number multiplied by the price per sq. ft. to give me a total price at that dimension (A3 is the width, B2 is the height, and A1 is the cell that contains the price per sq. ft.).
*Here is the problem*: When I try to cut and paste or fill the formula to the other cells, it doesn't calculate the formula as =CEILING(column A * Row B/144,1)*A1. Instead, it moves all of the values relative to the new cell that the formula is being pasted or filled to.
Is there a way to autofill the cells so that the formula continues to refer to the width column, the height row, and the price cell?

Aha! Apparently I didn't do enough research before I posted and I have since answered my own question. Here's how you do it. Look for "Distinguishing Absolute and Relative Cell References" and you should be able to find what you need. In my case, here is the formula I needed to have to make the copy and paste function do what I needed it to do: =CEILING($A3*B$2/144,1)*$A$. Hope that helps anyone who may have had the same problem I did.

Returning a serializable object from a java stored procedure

[Server : Oracle 8.1.6 on WinNT4 server. Client : java 1.2.2 on WinNT4 workstation.]
I am attempting to use a java stored procedure to build a complex serializable java object on the database (to minimise number of requests/queries on the network) and then return this object in response to the original query.
I have it writing a BLOB by means of
OutputStream os = retval.getBinaryOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(os);
oos.writeObject(v);
return retval;
where retval is a blob selected from a dummy table (created for this purpose) and v is a vector containing only serializable objects.
However, on the client side when I attempt to recover the object by
OracleResultSet rs = (OracleResultSet)stmt.executeQuery("SELECT javatest FROM DUAL");
oracle.sql.BLOB blob=rs.getBLOB(1);
InputStream inp = blob.getBinaryStream();
ObjectInputStream oinp = new ObjectInputStream(inp);
Vector retval = (Vector)oinp.readObject();
I get an exception telling me that the input stream does not contain an object at the line containing new ObjectInputStream(inp);
The full exception is :
java.io.StreamCorruptedException: InputStream does not contain a serialized object
at java.io.ObjectInputStream.readStreamHeader(ObjectInputStream.java:731)
at java.io.ObjectInputStream.<init>(ObjectInputStream.java:165)
at eRespond.DBLayer.JavaStoredProcedures.testdbobj.test2(testdbobj.java:143)
at eRespond.DBLayer.JavaStoredProcedures.testdbobj.main(testdbobj.java, Compiled Code)
I've checked that the returned blob is non-null, and that oracle.sql.BLOB is used throughout.
Any thoughts?
Thanks,
mark.

Firstly I guess to be able to new B() as a Thread, B
should extends Thread.
Secondly the constructor should not have any return
type:
public B(String cmd)
instead of
public void B(String cmd)
Lastly there is no need to override the start() method
if all it does is to call the superclass. The subclass
automatically inherits the method.
Hope this helps.thanks for replying so soon...
yes, you are right, it should extends Thread and it is, i forgot to out in this example... my mistake!
i'll try the construnctor thing to see if it works. bare in mind that i working with java stored procedures, it should work even so, right?
thanks

How to get the current selected column and row

Hi,
A difficult one, how do i know which column (and row would also be nice) of a JTable is selected?
e.g.
I have a JButton which is called "Edit" when i select a cell in the JTable and click the button "Edit" a new window must be visible as a form where the user can edit the a part of a row.
Then the column which was selected in the JTable must be given (so i need to know current column) and then i want the TextField (the one needed to be edited) be active with requestFocus(). So it would be
pricetextfield.requestFocus();
Problem now is that i have to click every time in the window the JTextField which was selected in the JTable. I have chosen for this way of editing because my application is multi-user and it would be too difficult for me when everybody did editing directly (catch signals, reload data, etc.).
My question is how do I know the current column and the current row in a JTable?

I'm not sure what your mean by the "current" row or column, but the following utility methods return
which row and column have focus within the JTable.
public static int getFocusRow(JTable table) {
return table.getSelectionModel().getLeadSelectionIndex();
public static int getFocusColumn(JTable table) {
return table.getColumnModel().getSelectionModel().getLeadSelectionIndex();
}
