how do you update a java.sql.date type in an ms access database
when i update a row in an access database the date field does not
update to the correct date it brings up some funny date which i dont
know where it comes from. Below is the method i use to update. maybe
the date types are not compatable?
thanks in advance,
public static void bookIN(int custID, int rNumber,java.sql.Date
bkInDate ){
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String filename = "hotelDB.mdb";
String database = "jdbc:odbc:Driver={Microsoft Access
Driver (*.mdb)};DBQ=";
database+= filename.trim() + ";DriverID=22;READONLY=true}";
Connection con = DriverManager.getConnection( database
,"","");
int yes = 1;
Statement s = con.createStatement();
s.executeUpdate("update Rooms set CustomerId
="+custID+",BookINDate ="+ bkInDate +",Occupied = "+yes+" where RoomNo
= "+rNumber+" ");
s.close();
con.close();
}
catch (Exception err) {
System.out.println("ERROR: " + err);
}
}

It comes from db's attempt to parse an invalid date-string...
In Access/Jet, it needs to be enclosed within #:s, and with the date parts
in a specific order...
Another thing is that java.sql.Date only contains the date part, whereas the
DateTime data type in Access/Jet is more like a java.sql.Timestamp.

Well, partly, but you're not using the date AS a date in the SQL statement,
but as a String. This will in most cases lead to errors, as the parsing of
such is left to the database, not the driver...
> s.executeUpdate("update Rooms set CustomerId=" + custID
> + ", BookINDate = " + bkInDate + ", Occupied = " + yes
> + " where RoomNo = " + rNumber + " ");
It's really bad practice to concatenate the string for an SQL statement in
that way, because of differences between different dbs. Instead you should
use a parameterized statement.
Use java.sql.Timestamp instead of java.sql.Date.

Read up on how to use a PreparedStatement, and it will solve your problem.

If you had written "Date classes" instead of "date classes" I would agree... ;-) But there are actually *more* than two date classes. In connection to JDBC, there are *four* "date"-classes to deal with. - There's our usual java.util.Date. Then there are the three classes derived from java.util.Date - java.sql.Date *derives* from java.util.Date, but "truncates" the "time part". - java.sql.Time *derives* from java.util.Date, but "truncates" the "date part". - java.sql.Timestamp *derives* from java.util.Date, but extends it with an attribute for nanoseconds. I'm not sure of the reasons behind Suns decision to name java.util.Date to only "Date", as it can cause much confusion, as in *many* other environments a "Date type" is just the date. I've met many developers that were confused when they couldn't find a java.util.Time class... ;-) // Bjorn A

Like in unix shells - bash for example? Guess what "time" and "date" do for you there. ;-)

Dates, Java, and Access Databases
I have a form created via NetBeans. I have an Access Database. I am correctly connected and can write to the database. However, I have three Date fields that I need some help with. First, I need to have formatted input on the Form Fields. Then I need to save the date to the database in the correct date/time (it's set up that way) format. My problem other than the formatted input is that there are times that one or more of the date Fields will be without data. I can't seem to get a blank field to write to the database properly. I get a data mismatch error whenever I try to send the blank field to the DB. Any help or suggestions would be appreciated.

java.sql.SQLException: java.sql.Time

I'm not a Java programmer - I don't know any Java, but ColdFusion acts essentially as a script layer to J2EE, so for some reason it's throwing a Java error. I'm especially stuck, because I need to resolve this without programming any Java, and the Adobe forums for ColdFusion and MySQL groups are no help. The error refers to the "VisitLength" field which is a "time" data type in the database. In the MySQL documentation, it says that 00:00:00 is allowable for time (http://dev.mysql.com/doc/refman/4.1/ en/ time.html). So my question is, why is this error coming up if it's an allowable value? And is there anything I can do? >So my question is, why is this error coming up if it's an allowable >value?

java.sql.SQLException: java.sql.Time
I get the following error message... java.sql.SQLException: Value '00:00:00 can not be represented as java.sql.Time >From the following SQL call... SELECT COUNT(pageurl) AS PageCount, pageurl, MAX(datetime) AS LastAccess, SUM(VisitLength) as TotalVisitLength, VisitLength, RecordNum, SUM(CASE WHEN VisitLength IS NULL THEN 1 ELSE 0 END) AS NullVisits FROM clubvisits WHERE groupid = #clubid# GROUP BY pageurl ORDER BY #OrderKey# I am using ColdFusion 7 on MySQL 4.1.12a. I'm not a Java programmer - I don't know any Java, but ColdFusion acts essentially as a script layer to J2EE, so for some reason it's throwing a Java error. I'm especially stuck, because I need to resolve this without programming any Java, and the Adobe forums for ColdFusion and MySQL groups are no help. The error refers to the "VisitLength" field which is a "time" data type in the database. In the MySQL documentation, it says that 00:00:00 is allowable for time (http://dev.mysql.com/doc/refman/4.1/ en/ time.html). So my question is, why is this error coming up if it's an allowable value? And is there anything I can do? >So my question is, why is this error coming up if it's an allowable >value? And is there anything I can do? one way is to store the values as raw ints or longs as far as SQL is concerned. -- Roedy Green Canadian Mind Products The Java Glossary http://mindprod.com <mehatespam1085@yahoo.com> wrote... ...
Passing java.lang.Class type as an argument to Java method
I am trying to set the default cell renderer for a JTable from within Matlab. All my efforts to this point have been based on Sun's 'How To Use Tables' tutorial. According to methodsview('JTable') the signature of the function is setDefaultRenderer(java.lang.Class,javax.swing.table.TableCellRenderer ) I cannot get this function to executed, and I think its because I cannot create a java.lang.Class argument from within Matlab. Following a corresponding code snipit: import javax.swing.*; import java.awt.*; import java.awt.event.*; columnNames = { 'First Name', &...

Unfortunately my crystal bowl stays dark because you didn't mentioned your operating system and which DB2 version you're using. For Windows, *nix and OS/2 please ensure that your application is using the db2java.zip from SQLLIB\java. Check if there are multiple db2jdbc.dll on your system, remove any extra db2jdbc.dll files on the system. Ensure that you can connect to DB2 with the DB2 workstation tools from your machine. sorry for not mentioning the system details. Operation System is SunOS (Solaris) and DB2 SDK 8.2.2 Thank you very much for the kind response, Ganesh Bernd Hohmann wrote: > ganesh.m@gmail...
