Null in PreparedStatement update

I am having trouble updateing values with a PreparedStatement when I use null as a value for one of the parameters. Example:
String sql = "UPDATE MYTABLE SET MYFIELD = ? WHERE MYKEY = ?";
PreparedStatement query = myConnection.prepareStatement(sql);
query.setString(1, null);
query.setString(2, "KEYVALUE");
query.executeUpdate();
This always results in the following error:
java.sql.SQLException: Missing IN or OUT parameter at index:: 1
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:187)
     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:229)
     at oracle.jdbc.driver.OracleStatement.checkBindsInAndOut(OracleStatement.java:1876)
     at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:2476)
     at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:452)
Is there another way to update something with a null value using a prepared statement?

Use
query.setNull(1,oracle.jdbc.OracleTypes.VARCHAR);
instead of query.setString(1, null);No, I tried that and it does not work either. The only time I am able to use nulls for the values in a prepared statement is if it is an insert statement. It does not seem to be possible with an update. Could someone verify that this is true?

Set null in PreparedStatement

Hi
I need to set null as a parameter in the PreparedStatement (that will behave as "is null" ).
the PreparedStatement.setNull is not working.
any ideas???

How did you use setNull() in your code? I'm sure there must be something wrong with the way you coded it.

Invalid use of Null: 'CStr' - checkbox UPDATE - what the heck?!

Jeesh...you just think you're beginning to understand things
and then
something "weird" happens! Anyway, what is wrong with this?:
<input <%If
(CStr((rsCustomer.Fields.Item("deletethis").Value)) =
CStr("True")) Then Response.Write("checked=""checked""") :
Response.Write("")%> name="deletethis" type="checkbox"
id="deletethis"
value="1" />
I have this as part of an UPDATE form. If I place a tick in
the checkbox,
and submit it, it updates the record correctly as having a 1
value (True).
If I open the same UPDATE form, for the same record, it
displays a check in
the check box - great.
However, if the "deletethis" in the user record is initially
"False" (0),
the default value for all of my records, and I submit the
update form
without changing the deletethis checkbox, it seems to be
submitting a blank
value which means that when I re-open the UPDATE form for
this record, and
submit the UPDATE again, I get this:
Error Type:
Microsoft VBScript runtime (0x800A005E)
Invalid use of Null: 'CStr'
//edit-customer.asp, line 838
I'm sure this is because it is trying to submit a blank
value, where it
needs to be either 0 or 1. But why is it submitting
"deletethis" as a blank
value?
When I check my SQL database, the deletethis field shows no
value, not even
the word NULL and certainly not a 1 or 0.
Also, if one of my records already has a 1 value, and I
change this in the
UPDATE form, but "unchecking" the deletethis checkbox, again
it submits a
blank value! Nyaarg!
For reference, here is my UPDATE code:
<%

Please, can someone just tell me what it is, because I can't

Much appreciated

Point taken David, ;o) but you must admit that Dreamweaver is
not strictly
marketed as such.
"With Dreamweaver 8, web developers go from start to finish,
creating and
maintaining basic websites to advanced applications that
support best
practices and the latest technologies."
(source:
http://www.adobe.com/uk/products/dreamweaver/)
Oh, and then there's the price tag! :-o
I personally think they could have marketed "Notepad" a
little better! :o)

Music store account city and state are perpetually "null" -asks for update

I am trying to buy something through the music store. All my information is there, but it keeps prompting me to update my billing information. My city and state are blank, so I type them in and hit 'done' and it asks me for my county information, which I update.
Then it returns me to the music store where I hit "buy song" again. Then I am prompted to log in and update my billing information all over again.

You can't. Apps are forever tied to the AppleID that purchased them. Delete the apps with the old AppleID and purchase them with the new AppleID.

How to insert a bean variable into MySql using jsp

Hi, I have a problem that I have been trying to work out for ages..unsuccessfully.
My web-site takes 2 inputs off a user...does a calculation on them and returns the result to the user.
I want to then use another jsp page that will take this result and insert it into a database...
My class code for this is :
public void updateRepmax(String userName, String repmax) throws SQLException, Exception{
     if(con != null){
     try{
     PreparedStatement update;
     update = con.prepareStatement("UPDATE repmax SET Benchpress = ?, WHERE Member_Name = ?");
     update.setString(1, repmax);
     update.setString(2, userName);
     update.execute();
     } catch(SQLException sqle){
     error = "SQLException: could not update repmax";
     throw new SQLException(error);
     catch(Exception e){
     error = "An exception occured while updating repmax";
     throw new Exception(error);
     } else {
     error = "Exception: connection to database was lost";
     throw new Exception(error);
My JSP is :
<%@page import="java.sql.*, placement.*"%>
<jsp:useBean id="conn" class="placement.DBConnect" />
<jsp:useBean id="query" class="placement.DBQuery" />
<jsp:useBean id="bpcalc" class="placement.repmaxBean" />
<jsp:useBean id="userin" class="placement.User" />
<html>
<head><title>Update Repmax</title></head>
<body>
<%
conn.connect();
     String repmax = bpcalc.getRepmax();
     String userName = userin.getUserName();
query.setCon(conn.getCon());
     query.updateRepmax();
conn.disconnect();
%>
     </body>
     </html>
The variable I am tryin to insert is repmax ,in the class that does the calculation the repmax is a double so I assume that is my first problem(how can this be changed to allow it to insert?)....any help you have to offer would be greatly appreciated...

Thanks for your reply sathishkb,
I am not actually receiving any error message,
The jsp page is processed and the code seems to be correct however the table in my mysql database is not updated.. my JDBC drivers are working correctly etc.
I expect that the problem is in my JSP page but dont know what it is
I have removed that comma in my update statement
I no longer have the problem of the variable being of type touble as I altered my other code to convert the variable from double to string
jsp is now:
<%@page contentType="text/html"%>
<%@page import="java.sql.*, placement.*"%>
<jsp:useBean id="conn" class="placement.DBConnect" />
<jsp:useBean id="update" class="placement.DBQuery" />
<jsp:useBean id="bpcalc" class="placement.repmaxBean" />
<jsp:useBean id="currentuser" class="placement.currentuserBean" />
<html>
<head><title>Insert Into Repmax</title></head>
<body>
<%
String repmax = bpcalc.repmax;
String userName =currentuser.name;
conn.connect();
     update.setCon(conn.getCon());
     update.updateRepmax(repmax,Username);
conn.disconnect();
%>
     </body>
     </html>
the segment of my bean code is :
public void updateRepmax(String repmax,String userName) throws SQLException, Exception{
     if(con != null){
     try{
     PreparedStatement update;
     update = con.prepareStatement("UPDATE repmax set Benchpress = ? WHERE Member_Name= ?");
     update.setString(1,repmax);
     update.setString(2,userName);
     update.execute();
     } catch(SQLException sqle){
     error = "SQLException: could not update employer";
     throw new SQLException(error);
     catch(Exception e){
     error = "An exception occured while updating employer";
     throw new Exception(error);
     } else {
     error = "Exception: connection to database was lost";
     throw new Exception(error);
}

Dg4odbc to MySQL update errors: "does not support IS NULL in this context"

I am having a problem with 'where x is null' clauses in update statements to MySQL from 11g, using dg4odbc. Updates using the clause 'where x is null' return errors like this:
ORA-02070: database PLAZAHOST does not support IS NULL in this context
The rejected queries never get to mysql. Furthermore, I noticed that select statements with 'where x is null' show up in the mysql query log with the where clause stripped out, although correct results are returned to SQLPlus. It looks as though 'where x is null' is stripped off by dg4odbc, which subsequently applies a secondary filter to the results received from MySQL.
Note, both statements above work properly when issued from the MySQL client.
Has anybody seen this? It's a big problem for me, but I can't find any references to other people having the same problem, so I assume I've got something misconfigured -- but I don't know what.
I'm using MySQL ODBC 5.1 Driver, MySQL 5.1 Community Edition, and Oracle 11g R1 all running on a 32-bit Windows server.
Thank you -- rick

is null statement is post processed. This means in case of a select ALL records from the remote database are fetched into the Oracle database and the is null statement is then processed locally in the Oracle db.
So thze select will work as it is handled internally in the Oracle database. This also means as But "is null" isn't sent to the foreign MySQL db the update clause will fail with ORA-02070: database PLAZAHOST does not support IS NULL in this context
You need to recode the statement or use passthrough statements.

Hi,
"=" will not work for NULL values. Please remeber two NULL values are NOT same. Try IS operator.

Update record to specific value or to null

Hello.
We have two tables. Both have the same attribute. Update sentence look if attribute has the same value in both tables. If the value is the same, another attribute is updated to specific value in one table.
Now i want to update attribute in all records. But if the both tables haven't got the same value, attribute in record should be updated to null.
For now update looks like:
update tableA set att1 = att2
where att3 = value2 and att4 IN (select att4 from tableB where att2 = value2);
Any idea?
I hope i explained the problem properly.
Thanks.

Like..
SQL> select * from test1;
C1         C2
c1          1
SQL> select * from test2;
C1        C22        C33
c2         11        100
c1          1        100
SQL> update test2 t2
2 set c33 = decode(c22,(select max(c2) from test1 t1 where t1.c1=t2.c11),0,null);
2 rows updated.
SQL> select * from test2;
C1        C22        C33
c2         11
c1          1          0

Any suggestions ?????

i don't see how not setting the autoCommit parameter
has anything to do with this.If autocommit is false then an update will not be committed without an explicit commit()!
>
I would like to add one more thing in here, which m
sorry i shud hav added; this particluar fn. does
update a lot of row; but for some records, althou it
does say that it has updated(java API ); but in
reality it does not do it.
That makes a lot fo difference! It does mean that it is probably not a commit problem but without this extra information my money was on a commit problem. Are you swallowing an exception without reporting it?

How to retrieve a SQL query (in String format) from a PreparedStatement

Hello all,
I am in the process of unit testing an application accessing a Oracle 9i 9.2 RDBMS server with JDBC.
My query is:
As I have access to PreparedStatement and CallableStatement Java objets but not to the source queries which help create those objects?
Is thtere a simple way by using an API, to retrieve the SQL command (with possible ? as placeholders for parameters).
I have already looked at the API documentation for those two objets (and for the Statement and ResultSetmetaData objects too) but to no avail.
Thank you for any help on this issue,
Best regards,
Benoît

Final word:
The final word about this is: there is currently three ways to obtain source SQL queries from compiled statement objects.
a) Use a proxy class the mConnector above;
b) Use a proxy JDBC driver as Log4JDBC;
c) Use the trace facility of the driver (however, post analyzing the logs would depend upon the driver selected).

One problem is that you misspelled "SimpleDateFormat". You seemed to make the "i" upper case: "SImpleDateFormat".

PreparedStatement.executeBatch() and BatchUpdateException

Hi,
I am using PreparedStatement's executeBatch() method to make batch operations,
for such a scenario is there a way to continue the operation 3 and 4 when the operation 2 fails?
operation 1 (will succeed alone)
operation 2 (will fail alone)
operation 3 (will succeed alone)
operation 4 (will succeed alone)

Hi, I've already looked the link you've sent.
Let me give more detail about the result of my scenario.
The first two successfull insert operations really updates the database which is Oracle.
But it seems the failed 3rd operation prevents the operation 4 to update database.
My code is something like that:
int[] updateCounts = null;
try {
PreparedStatement stmtInsert = conn.prepareStatement("insert sql");
for (int i=0; i <SOMEVALUE; i++)
     stmtInsert.setString(1, SOMEVALUE);
     stmtInsert.setString(2, SOMEVALUE);
     stmtInsert.addBatch();
int[] counts = stmtInsert.executeBatch();
} catch (BatchUpdateException e)
updateCounts = e.getUpdateCounts();
checkUpdateCounts(updateCounts);
finally {
conn.close();
public static void checkUpdateCounts(int[] updateCounts) {
for (int i = 0; i < updateCounts.length; i++) {
if (updateCounts[i] == Statement.SUCCESS_NO_INFO) {
// Successfully executed; number of affected rows not available
System.out.println("Statement.SUCCESS_NO_INFO");
} else if (updateCounts[i] == Statement.EXECUTE_FAILED) {
System.out.println("Statement.EXECUTE_FAILED");
The results are pretty confusing, as I said first two operations updates the db, but fourth is did not.
But system out says:
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
I would expect something like that:
Statement.SUCCESS_NO_INFO");
Statement.SUCCESS_NO_INFO");
Statement.EXECUTE_FAILED
Statement.EXECUTE_FAILED
or even better (assuming operation 4 updated the db)
Statement.SUCCESS_NO_INFO");
Statement.SUCCESS_NO_INFO");
Statement.EXECUTE_FAILED
Statement.SUCCESS_NO_INFO");
Since the size of the int array that the e.getUpdateCounts() is 4 which is also equal of the batch operations' size, I assume that the driver continues to process the commands in the batch after a BatchUpdateException is thrown.
I am totally confused, can anybody comment these results? Is there a way to succeed the fourth operation?

Updating a table via a gui program

i am trying to update a record via the UPDATE function. My program has a show all button that brings in all the records. When i make a change in the record and click Update. I get the error: Syntax error in string in query expression ''00000' the zeroes represent an updated zipcode. Here is my source code for the update function:
if(e.getActionCommand().equals("Update"))
String url = "jdbc:odbc:coffee";
String driver= "sun.jdbc.odbc.JdbcOdbcDriver";
Connection con= null;
Statement stmt =null;
//PreparedStatement stmt = null;
ResultSet my_result= null;
/* String query = "Update CoffeeSuppliers set " +
"Name='" + comp_Name.getText() +
"', Address='" + comp_Addr.getText() +
"', City ='" + comp_City.getText() +
"', State='" + comp_State.getText() +
"', ZipCode='" comp_zipcode.getText()
"' WHERE ID=" + comp_ID.getText();
String query= "Update CoffeeSuppliers set " +
"ID='" + comp_ID.getText() +
"', Name='" + comp_Name.getText() +
"', Address='" + comp_Addr.getText() +
"', City='" + comp_City.getText() +
"', State='" + comp_State.getText() +
"', ZipCode='" + comp_zipcode.getText();
try
Class.forName(driver);
catch(java.lang.ClassNotFoundException exception)
System.err.print("ClassNotFoundException: ");
System.err.println(exception.getMessage());
try
con = DriverManager.getConnection(url,"app","app");
stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
my_result= stmt.executeQuery(query);
stmt.executeUpdate(query);
while(my_result.next())
System.out.println("am i in the while loop");
my_result.updateString(1,comp_ID.getText());
my_result.updateString(2,comp_Name.getText());
my_result.updateString(3,comp_Addr.getText());
my_result.updateString(4,comp_City.getText());
my_result.updateString(5,comp_State.getText());
my_result.updateString(6,comp_zipcode.getText());
my_result.updateRow();
stmt.close();
con.close();
catch(SQLException sqlex)
System.err.println("ERROR: " + sqlex.getMessage());
} //end of the if statement
Any feedback will be great.
thanks

String query= "Update CoffeeSuppliers set " +
"ID='" + comp_ID.getText() +
"', Name='" + comp_Name.getText() +
"', Address='" + comp_Addr.getText() +
"', City='" + comp_City.getText() +
"', State='" + comp_State.getText() +
"', ZipCode='" + comp_zipcode.getText() + "'";I think that it is as simple as the fact that you diddn't close the zipcode string literal being passed to the SQL interpreter. Add the closing ' to the query
Hope this helps,

Pass variables and return ResultSet from same preparedStatement

I am passing "fp" and "week_no" to a preparedStament in a class and want to return the values to my jsp page. "fp" and "week_no" are used twice. Please see below. When I run it, I get no error messages but, it doesn't display any data.
I have the following code in a class:
public ResultSet getHistory(String fp, String week_no)
                    throws SQLException, Exception {
ResultSet rs = null;
if (con != null) {
try {
     PreparedStatement getHist;
     getHist = con.prepareStatement(
     "SELECT sbu, TO_CHAR(((sum_dollar) + (adj_sum_dollar)),'$999,999,999.99') AS sum_dollar, TO_CHAR(actual_date,'MM/DD/YY') AS actual_date, " +
     "((sum_cases) + (adj_sum_cases)) AS sum_cases, " +
     "((new_order_cases) + (adj_new_order_cases)) AS new_order_cases, " +
     "((total_open_orders) + (adj_total_open_orders)) AS total_open_orders, " +
     "((back_orders) + (adj_back_orders)) AS back_orders, " +
     "TO_CHAR((sum_dollar/sum_cases), '999.99') AS yield " +
     "FROM SUMMARY " +
     "WHERE actual_date BETWEEN (SELECT begin_dt " +
               "FROM fiscal_calendar " +
                         "WHERE fiscal_period = '?' " +
                         "AND week_number = '?' " +
                         "AND week_number <> '9' " +
                         "AND fiscal_yr = '2003') " +
                    "AND " +
                         "(SELECT end_dt " +
                    "FROM fiscal_calendar " +
                         "WHERE fiscal_period = '?' " +
                         "AND week_number = '?' " +
                         "AND week_number <> '9' " +
                         "AND fiscal_yr = '2003') " +
          "ORDER BY actual_date, sbu ");
     getHist.setString(1, fp);
     getHist.setString(2, week_no);
     getHist.setString(3, fp);
     getHist.setString(4, week_no);
     rs = getHist.executeQuery();
     } catch (SQLException sqle) {
error = "SQLException: Update failed, possible duplicate entry.";
     throw new SQLException(error);
} else {
error = "Exception: Connection to the database was lost.";
     throw new Exception(error);
return rs;
This is in my jsp:
<%
String fp = request.getParameter("fp");
String week_no = request.getParameter("week_no");
historyInfo.connect();
ResultSet rs = historyInfo.getHistory(fp, week_no);
while (rs.next()) {
//String sum_dollar = rs.getString("sum_dollar");
%>
<%= rs.getString("sum_dollar") %>
<%
%>

Hi,
First thing U can't do this way in java. If U are executing this sort of database query, after retriving all the values, put inside Haahtable or HashMap as the application required and return it.
Otherwise execute this query at the same place where u r printing values in jsp page insted of writing it inside seperate method..It will work.
If still it's not workimg, please let me know.
