I have an update method to update the content of a table based on a specific field and I am getting following exception.
Code is :
public void updateTaxoActive(String oldDesc, String description) {
Logger.getLogger(TypeCategoryJDBCTemplate.class.getName()).log(Level.INFO, "old taxonomy code is {0} new description is {1}", new Object[]{oldDesc, description});
String sql = "update product.typecategory set taxonomydescription = ? where taxonomydescription = ?";
jdbcTemplateObject.update(sql, new Object[]{description,oldDesc},new TypeCategoryMapper());
}
Exception is:
Exception in thread "AWT-EventQueue-0" org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [update product.typecategory set taxonomydescription = ? where taxonomydescription = ?]; nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][1091][10824][4.13.127] Invalid data conversion: Parameter instance [Ljava.lang.Object;#1dc421 is invalid for the requested conversion.

I need to read a date from a JDateChooser and save it into a MYSQL database table using the ActionPerformed method of a JButton.
There are three JDateChoosers called LETTER_DATE , RECEIVED_DATE , SENDING_DATE in this JInternalFrameForm called LETTER .
Below is the code of the ActionPerformed method of the JButton SAVE which will save the data into the MYSQL table.
private void SAVEActionPerformed(java.awt.event.ActionEvent evt) {
try{
Statement s=DB.getConnection().createStatement();
s.executeUpdate("insert into LETTER values('"+LETTER_ID.getText()+"','"+LETTER_CATEGORY.getSelectedItem()+"','"+LETTER_DATE.getDate()+"','"+HEADING.getText()+"','"+SECTION_ID.getSelectedItem()+"','"+SUBJECT_ID.getSelectedItem()+"','"+INSTITUTE_ID.getSelectedItem()+"','"+NEW_INSTITUTE.getText()+"','"+SENDERS_ID.getSelectedItem()+"','"+NEW_SENDER.getText()+"','"+RECEIVED_DATE.getDate()+"','"+RECEIVERS_ID.getSelectedItem()+"','"+NEW_RECEIVER.getText()+"','"+SENDING_DATE.getDate()+"')");
JOptionPane.showMessageDialog(this, "Saved");
}
catch(Exception ex){
ex.printStackTrace();
}
}
When I clicked the JButton to save the data, it gives the following stacktrace.
com.mysql.jdbc.MysqlDataTruncation: Data truncation: Incorrect datetime value: 'Mon Dec 04 14:45:36 PST 2017' for column 'LETTER_DATE' at row 1

Can anyone please help me to figure out the problem here and correct the datetime value for column ['LETTER_DATE'][1] at row 1?
Well, you should be using getDateFormatString() instead of getDate(). For instance:
s.executeUpdate("insert into LETTER values('"+LETTER_ID.getText()+"','"+LETTER_CATEGORY.getSelectedItem()+"','"+LETTER_DATE.getDateFormatString()+"','"+HEADING.getText()+"','"+SECTION_ID.getSelectedItem()+"','"+SUBJECT_ID.getSelectedItem()+"','"+INSTITUTE_ID.getSelectedItem()+"','"+NEW_INSTITUTE.getText()+"','"+SENDERS_ID.getSelectedItem()+"','"+NEW_SENDER.getText()+"','"+RECEIVED_DATE.getDateFormatString()+"','"+RECEIVERS_ID.getSelectedItem()+"','"+NEW_RECEIVER.getText()+"','"+SENDING_DATE.getDateFormatString()+"')");
I'm Trying to run this code to get the ResultSet row by row into an Array so i can put them in a jTable. I don't get why i get this error, i'm new in this.
I would be totally thankfull if you could help me.
try {
int pos = 1;
for (int r=0;r<rsCount;r++){
String[] na = null;
res.absolute(pos);
int a=1;
while(res.next()){
na[a]=res.getString(a+1);
a+=1;
}
pos+=1;
for(int c=0;c<8;c++){
tabla.setValueAt(na[c], r, c);
}
}
} catch (SQLException ex) {
Logger.getLogger(Reporte.class.getName()).log(Level.SEVERE, null, ex);
}
}
And here is the OUTPUT:

Your string array is not being properly instantiated. You need to instantiate it like:
String[] na = new String[100];
If you don't know how big the array is going to be you might want to consider using an ArrayList
ArrayList<String> na = new ArrayList<String>();
then each string can be added with:
na.add(res.getString(a+1));
I have had a few problems trying to get this table to show in NetBeans. Here is the code that I am trying to use. I am aware that the loop is wrong and will fix that at a later date.
I get a runtime error with the following code and I can't work it out.
Object[][] data = null;
String[] columnNames = {"Type", "Grade", "Height", "Width", "Length", "Reinforced Bottom", "Reinforced Corners", "Sealable", "Quantity"};
JTable table = new JTable();
public void showTotalOrder(){
for(int i=0; i<boxes.size(); i++){
for(int j=0; j<1; j++){
data[i][j] = boxes.get(i).getName();
data[i][j+1] = boxes.get(i).getGrade();
data[i][j+2] = boxes.get(i).getHeight();
data[i][j+3] = boxes.get(i).getWidth();
data[i][j+4] = boxes.get(i).getLength();
data[i][j+5] = boxes.get(i).getReinforcedBottom();
data[i][j+6] = boxes.get(i).getReinforcedCorners();
data[i][j+7] = boxes.get(i).getSealable();
data[i][j+8] = boxes.get(i).getQuantity();
}
}
JOptionPane.showMessageDialog(this, table);
}
I believe the problem is with the last line of this method.
The error i receive is:

You get a NullPointerException because of data array is initialized to null:

I'm using mysql and having select fields from a gui append to my query. However, I'm getting a mysql exception for this query: String query = "INSERT INTO racebikes " + "VALUES(?,?,?)";
For testing measures I printed out the query to make sure the fields were proper which when populated read as: INSERT INTO racebikes VALUES('BMC','Switzerland',10000.0). How is this throwing an syntax exception?

Can you try to put the three fields before VALUES
String query = "INSERT INTO racebikes (field1, field2, field3)" + "VALUES(?,?,?)";
Replace them with your actual field names.
Good time, everyone. I have a bad issue in my code. When I compile it, it doesn't works like I expected and returns me too many exceptions.

First one at kazemirdo.KazemirdoMatcher.KazemirdoMatcherAct(KazemirdoMatcher.java:53) refers:
public void KazemirdoMatcherAct() {
requestWords = kC.getRequestBuffer();
int j = 0;
// Searchs the matches
for (String match : requestWords) { // Refers right here.
p = Pattern.compile(match + "\t.*");
for (int i = 0; i < morphBuffer.length; i++) {
if (morphBuffer[i] == null) {
buffer[j] = morphBuffer[i+1];
}
else {
m = p.matcher(morphBuffer[i]);
if(m.find()) j++;
}
}
}
}
Second exception refers to place, when I'm calling KazemirdoMatcherAct() method.
But others.. I can't understand, really.
What I do wrong?
Whole code, if needed: http://fpaste.org/62123/18201713/
Maybe you can System.out.print the requestWords in KazemirdoConverter,see what is the String request.
