Need help using Select statement to retrieve one record

Hi guys, my first post so be gentle please. The basis of this fucntion is to search my dtabase using the select statement to find the record the user wants, by retrieving the name of theitem from the text box. details are then displayed on a joption message box.
Everytime I run this program it throws an exception 'Exception: null'. Can anyone see where I am going wrong, I have only bn learning java for thepast 6 months so perhaps I am doing something wrong.
Or perhaps there is another way for me to close the st, con, rs?
Your help appreciated
public void searchproducts(){
Connection con = null;
Statement st = null;
ResultSet rs = null;
try{
//creating and loading a database connection
String dbUrl = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=db2.mdb;"; // String dbUrl = "jdbc:odbc:people";
String user = "";
String password = "";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c = DriverManager.getConnection(
dbUrl, user, password);
int count;
st = con.createStatement();
rs = st.executeQuery("SELECT ItemName, Country, Yearmade, ValuePrice, Forsale FROM Collectman WHERE ItemName="+" '"+txtsearchproduct.getText()+"'" );
while(rs.next()) {
String ItemName = rs.getString(1);
String Country = rs.getString(2);
String Yearmade = rs.getString(3);
String ValuePrice = rs.getString(4);
String Forsale = rs.getString(5);
JOptionPane.showMessageDialog(null, "product details are: " + ItemName + " " + Country + " " + Yearmade + " " + ValuePrice + " " + Forsale);
//It keeps on throwing this excpetion with null
catch (Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(rs != null)
rs.close();
if(st != null)
st.close();
if(con != null)
con.close();
} catch (SQLException e) {
}

And while we're waiting on that, I'll just say it's nice to see you almost got the general layout of a db call correct...that's a rare thing around here. The finally should have a try/catch round each of the close statements and not around all three in one go. If the resultset throws an exception in your version then you would fail to close either the statement or the connection.
The second thing is, look up PreparedStatements. They're a better choice for handling SQL requiring variables than using a bog standard Statement.

Need help with select statement or query

Not familiar with what to call it, but here is what i need...
To give our analyst a better idea of warranty on some of our
equipment, i
would like to add to the page a column that displays if the
device is still
under warranty
I currently capture the date the equipment was returned from
repair, so what
could i use within my select statement or query to display a
warranty
expiration date or display on the page...
example :
Returned from repair 10/20/2006 warranty expires on
11/20/2006
each equipment has different warranties, so i need a formula
or something to
say... device #1 has 60 day warranty ( so 10/20/2006 + 60days
=
12/19/2006 )
I would imagine this to be a query
Table 1 would contain the equipment type and warranty time
Table 2 would contain the current status of the equipment
Query would take the back from repair date + warranty =
expiration date

Simple. Join the two tables and create a derived column for
the expiration date. The exact syntax is dependant on your DBMS, so
check the manual for whichever you are using and look at the date
functions. There will be a function that will allow you to add a
number of date units (day, month, year, etc) to a date
field.

       MODIFY itab1.
       ELSE.
    ENDIF.
ENDLOOP.
Please Help
Regards
Saad Nisar

Hello Saad,
The reason why you are not getting the 2nd and 5th entries is that, the where conditions vbelv, posnn and vbtyp_n matches for both the 1st and 2nd record where select will pick only the 1st record. The same way for 4th and 5th record. so its picking only 4th.
So to avoid this add even vbeln in the where condition of the select query
LOOP AT itab1.
    SELECT SINGLE * INTO CORRESPONDING FIELDS OF wa_vbfa
    FROM vbfa
    WHERE vbelv = itab1-vgbel
    AND posnn = itab1-vgpos
   AND vbeln = itab1-field           " Add the corresponding field here
    AND vbtyp_n = 'M'.
    SELECT SINGLE * INTO CORRESPONDING FIELDS OF wa_vbrk
      FROM vbrk
      WHERE vbeln = wa_vbfa-vbeln
      AND vbtyp = 'M'.
    IF sy-subrc = 0.
        itab1-lfimg = wa_vbfa-rfmng.
       itab1-old_price = wa_vbfa-rfwrt.
       MODIFY itab1.
       ELSE.
    ENDIF.
ENDLOOP.

Number of rows inserted is different in bulk insert using select statement

I am facing a problem in bulk insert using SELECT statement.
My sql statement is like below.
strQuery :='INSERT INTO TAB3
(SELECT t1.c1,t2.c2
FROM TAB1 t1, TAB2 t2
WHERE t1.c1 = t2.c1
AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery ;
These SQL statements are inside a procedure. And this procedure is called from C#.
The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is *70*.
But in the next time call (in the same transaction) of the procedure, the number rows inserted is only *50*.
And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.
On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.
Anybody faced these kind of issues?
Can anyone tell what would be the reason of this issue..? any other work around for this...?
I am using Oracle 10g R2 version.

You have very likely concurrent transactions on the database:
>
By default, Oracle Database permits concurrently running transactions to modify, add, or delete rows in the same table, and in the same data block. Changes made by one transaction are not seen by another concurrent transaction until the transaction that made the changes commits.
>
If you want to make sure that the same query always retrieves the same rows in a given transaction you need to use transaction isolation level serializable instead of read committed which is the default in Oracle.
Please read http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10471/adfns_sqlproc.htm#ADFNS00204.
You can try to run your test with:
set transaction isolation level serializable;If the problem is not solved, you need to search possible Oracle bugs on My Oracle Support with keywords

FETCHING VALUES IN MULTI RECORD BLOCK FROM ANOTHER TABLE USING SELECT STATEMENT.

Hi,
I have one multi record block in which i want to fetch values
(more then one record) from another table using select statement
IN KEY NEXT ITEM.I am getting following error.
ORA-01422: exact fetch returns more than requested number of rows
Thanks in advance.

In your case I see no reason to use non-database block and to try to populate it from a trigger with a query, instead of using the default forms functionality where you can associate the block and the fields with table, create where clause using bind variables and simply use execute_query() build-in to populate the block. The power of the forms is to use their build-in functionality to interact with the database.
Also, you can base your block on a query, not on a table and you dynamically change this query using set_block_property() build-in. You can use any dynamic queries (based on different data sources) and you simply need to control the column's data type, the number of the columns and their aliases. Something like creating inline views as a block data source.
However, you can replace the explicit cursor with implicit one like
go_block('non_db_block_name');
first_record();
FOR v_tab IN (SELECT *
FROM tab
WHERE col_name = :variable)
LOOP
:non_db_block_name.field1 := v_tab.col1;
:non_db_block_name.field2 := v_tab.col2;
next_record();
END LOOP;

Using Select statement in IF condition?

Can i use select statements in LDB

Hai All,
Can i use select statements and internal table in a LDB program.
my requirement is that if i enter company code , fiscal year and reporting periods.
generally fiscal year will be jan to dec.but in my requirement the fiscal year is apr of previous year to march of currentyear.
so as i require the last years data can iuse select statement in that ldb program or is there any solution for this.
Thanks in Advance
kiran

Hi Kiran,
To retrive records from ldb you have to use the
GET <node> statement. This will invoke the selection screen of the node. An alternate solution is to use the function module LDB_PROCESS.
Please see the following link for help and example
