I want to insert a date in the database, but it does not work any error message that appears. When I look at my table in Oracle DB I can not find my data that I inserted.
java.util.Date daterecep;
// getter and setter
public void setdaterecep( java.util.Date daterecep) {
this.daterecep=daterecep;
}
public java.util.Date getdaterecep() {
return daterecep;
}
and
nt val=0;
try {
val = st.executeUpdate("insert into tabdate (date) values('"+daterecep+"')" );
} catch (SQLException ex) {
Logger.getLogger(Insertdate.class.getName()).log(Level.SEVERE, null, ex);
}
System.out.println(val);
return resultat;
}
I used PreparedStatement but it did not worked I just tried to execute the Java code
val = st.executeUpdate("insert into tabdate(date) values('12/12/2004')");
and add
public static void main (String args[]) throws SQLException {
Insertdate B= new Insertdate();
B.connexionBD();
B.insert();//function for the insertion
}
and it works.
Here,
values('"+daterecep+"')
you're basically attempting to store the result of daterecep.toString()
in the database. As per the documentation this is in format like as "Sat Jun 6 10:43:00 BOT 2011" (which depends on the locale and timezone.). The database does not understand it.
You should be using PreparedStatement#setTimestamp()
to set a DATETIME
/ TIMESTAMP
field in a DB.
preparedStatement = connection.prepareStatement("insert into tabdate (date) values(?)" );
preparedStatement.setTimestamp(1, new Timestamp(daterecep.getTime()));
preparedStatement.executeUpdate();
Or when it's actually a DATE
field, use setDate()
instead.
preparedStatement.setDate(1, new java.sql.Date(daterecep.getTime()));
As a bonus, PreparedStatement
also saves you from SQL injection attacks .
