Show results on Jtable between dates when selected Jdatechooser (Mysql)

This is the query for the (between dates). But when I select the dates and click OK all records on JTable disappears. Help me to build the query and statement for the get record between dates on JTable.
Jtable with records
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here
// java.util.Date val1 = jDateChooser1.getDate();
// java.util.Date val2 = jDateChooser2.getDate();
java.sql.Date val1 = new java.sql.Date(jDateChooser1.getDate().getTime());
java.sql.Date val2 = new java.sql.Date(jDateChooser2.getDate().getTime());
try {
String sql = "select * from Umar where Date between ? and ? ";
pst = conn.prepareStatement(sql);
pst.setDate(1, val1);
pst.setDate(2, val2);
rs = pst.executeQuery();
jTable1.setModel(DbUtils.resultSetToTableModel(rs));
} catch (Exception e) {
JOptionPane.showMessageDialog(null,e);
}
}

Once again we know nothing about your database. It is up to you to know how the data is displayed in the database.
Here is a simple query to get you started.
String sql = "Select * from Umar";
PreparedStatement ps = connection.prepareStatement();
ResultSet rs = ps.executeQuery( sql );
ResultSetMetaData md = rs.getMetaData();
int columns = md.getColumnCount();
// Get column names
for (int i = 1; i <= columns; i++)
{
System.out.println( md.getColumnLabel(i) );
}
// Get row data
while (rs.next())
{
for (int i = 1; i <= columns; i++)
{
Object data = rs.getObject(I);
System.out.println(data + " : " + data.getClass());
}
}
rs.close();
stmt.close();
This has absolutely nothing to do with your JTable. It is just a query of the database. So get this query working. Determine how the date is stored in your database. Is it a String or a Date?
Then next you change the query:
String sql = "Select * from Umar where Date between ? and ? ";
...
ps.setDate/String(1, ...);
ps.setDate/String(2, ...);
Then you test this with a hard coded data to make sure you get data. Then once this step is working you fix your program that loads the data into the JTable.

Using PreparedStatement to sort records in MySQL

Im trying to write a code in which when a user will click an a "Sort by Name" button, my program will sort the records of my Database and put them in a JTable,combining 2 DB Tables with INNER JOIN. I have managed to do this by using a resultSet and selecting for example Ascending Order. But because I dont want to have 2 buttons, one for the ASC and one for the DESC, I thought of using preparedStatement and an showInputDialog in which the user will select if he wants to have an ASC or a DESC ordering and execute the order. Also, I remembered that some programs I've seen used a feature in which the first time you clicked the button it sorted DESC and if you pressed it again would order by ASC(havent managed to find in on the WEB).About my first thought, I tried to do it but I could get past this one
ResultSetMetaData mdsort = rssort.getMetaData();
I should have an ResultSet variable(rssort) to use getMetaData() but if I selected to make the program with my PreparedStatement i would get an error there. Any suggestions??
try{
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/test1?user=me&password=12345");
Statement stmtsort = conn.createStatement();
ResultSet rssort = stmtsort.executeQuery("SELECT * FROM consoles INNER JOIN hardware ON consoles.id=hardware.id ORDER BY consoles.name ASC");
// ERROR HERE!!! needs resultset,not preparedStatement
ResultSetMetaData mdsort = rssort.getMetaData();
columnCount = mdsort.getColumnCount();
String[] colssort = new String[columnCount];
for (i=1;i<= columnCount;i++)
{
colssort[i-1] = mdsort.getColumnName(i);
}
DefaultTableModel model = new DefaultTableModel(colssort,0);
while (rssort.next())
{
Object[] rowsort = new Object[columnCount];
for (i = 1 ; i <= columnCount ; i++)
{
rowsort[i-1] = rssort.getObject(i);
}
model.addRow(rowsort);
}
JTable table = new JTable(model);
model.fireTableDataChanged();
table.setCellSelectionEnabled(true);
table.setColumnSelectionAllowed(true);
table.setFillsViewportHeight(true);
table.setSurrendersFocusOnKeystroke(true);
table.setBounds(218,59,529,360);
frame.getContentPane().add(table);
model.fireTableDataChanged();
conn.close();
stmtsort.close();
rssort.close();
} catch (SQLException case1)
{case1.printStackTrace();
} catch (Exception case2)
{case2.printStackTrace();}
}
});
UPDATE
OK I managed to fix this issue with the getMetaData() but now the thing is that I dont use any ResultSet variables/instances and cant use next() method to create my DB.
String name = "SELECT * FROM consoles INNER JOIN hardware ON consoles.id=hardware.id ORDER BY consoles.name ?";
PreparedStatement psname = conn.prepareStatement(name);
String strin = JOptionPane.showInputDialog(null,"ASC or DESC order ? : ");
psname.setString(1,strin);
psname.executeUpdate();
ResultSetMetaData mdsort = psname.getMetaData();
int columnCount = mdsort.getColumnCount();
.
.
.
// error coming up here,because i deleted the ResultSet
while (psname.next())
.
.
.

Better make a bit more complex TableModel.
That is more optimal.
Keep the data from the ResultSet in an original TableModel.
Use a wrapping TableModel to sort, and maybe filter.
Use the ResultSetMetaData for the column type, if it is Number (Integer, BigDecimal, ...) then use that type instead of Object for the column type: gives a right aligned column.
Maybe first do an internet search for ResultSetTableModel; other peoply must have done it already.

try{
conn = DriverManager.getConnection("jdbc:mysql://localhost/test1?user=me&password=12345");
String strin = JOptionPane.showInputDialog(null,"ASC or DESC order ? : ");
stmtsortname = conn.createStatement();
rssortname = stmtsortname.executeQuery("SELECT * FROM consoles INNER JOIN hardware ON consoles.id=hardware.id ORDER BY consoles.name "+strin);
mdsortname = rssortname.getMetaData();
columnCount = mdsortname.getColumnCount();
String[] colssortname = new String[columnCount];
for (i=1;i<= columnCount;i++)
{
colssortname[i-1] = mdsortname.getColumnName(i);
}
model = new DefaultTableModel(colssortname,0);
while (rssortname.next())
{
Object[] rowsortname = new Object[columnCount];
for (i = 1 ; i <= columnCount ; i++)
{
rowsortname[i-1] = rssortname.getObject(i);
}
model.addRow(rowsortname);
}
table = new JTable(model);
model.fireTableDataChanged();
table.setCellSelectionEnabled(true);
table.setColumnSelectionAllowed(true)
table.setFillsViewportHeight(true);
table.setSurrendersFocusOnKeystroke(true);
table.setBounds(146,59,763,360);
frame.getContentPane().add(table);
model.fireTableDataChanged();
conn.close();
stmtsortname.close();
rssortname.close();
} catch (SQLException case1)
{
case1.printStackTrace();
}
catch (Exception case2)
{
case2.printStackTrace();
}
}

Deleting selected row in MySQL database through JTable

tb_records = jtable name
records = table name inside my database
Date = my first column
hey = substitute for my real password
mydatabase = name of my database
My problem is that, when I highlight a row in my JTable and delete it, it deletes all the rows. I want to delete the selected row only. Here's my code:
int row = tb_records.getSelectedRow();
DefaultTableModel model= (DefaultTableModel)tb_records.getModel();
String selected = model.getValueAt(row, 0).toString();
if (row >= 0) {
model.removeRow(row);
try {
Connection conn = (Connection) DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "root", "hey");
PreparedStatement ps = conn.prepareStatement("delete from records where Date='"+selected+"' ");
ps.executeUpdate();
}
catch (Exception w) {
JOptionPane.showMessageDialog(this, "Connection Error!");
}
}
What could be the problem here? How can I delete a selected row in my database and not all the rows?

DefaultTableModel model = (DefaultTableModel) jTable.getModel();
int row = jTable.getSelectedRow();
String eve = jTable.getModel().getValueAt(row, 0).
String delRow = "delete from user where id="+eve;
try {
ps = myCon.getConnection().prepareStatement(delRow);
ps.execute();
JOptionPane.showMessageDialog(null, "Congratulation !!");
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e.getMessage());
}

1) Don't display your own message. Display the error message from the Exception as it will give a better explanation what the problem is.
2) Use a proper PreparedStatement for the SQL. You are less likely to make syntax errors. Something like:
String sql = "delete from records where Date= ?";
PreparedStatement stmt = connection.prepareStatement(sql);
stmt.setString( 1, selected );
stmt.executeUpdate();
I don't know much about SQL but maybe you need to pass a Date object not a String object since your where clause is using a Date?

The OP wrote:
SOLUTION: Pick a column with unique values. My Date column has the same values that's why it's deleting all my rows even though I set my row as getSelectedRow. Time_in = my 4th column with unique values.
change
String selected = model.getValueAt(row, 0).toString();
to
String selected = model.getValueAt(row, 3).toString();
and
PreparedStatement ps = conn.prepareStatement("delete from records where Date='"+selected+"' ");
to
PreparedStatement ps = conn.prepareStatement("delete from records where Time_in='"+selected+"' ");

ResultSet returns only last row into JTable

I have done enough searches to solve my problem which i have done partly but there's this one bug that keeps disturbing me.I am trying to fetch data from a database based on a condition.I have a table 'user_branch' with a foreign key column branchID which is supposed to fetch the coresponding branchNames in another table 'branches' and I am supposed to display the results into a JTable.When i do System.out.println i get all my results but it returns only the last row when i display in a JTable(branchJTable).This is the code i am using
int row = user2BAssignedJTable.getSelectedRow();
assignUserID.setText(user2BAssignedJTable.getModel().getValueAt(row, 0).toString());
user2BAssignedField.setText(user2BAssignedJTable.getModel().getValueAt(row, 1).toString());
try {
String userBrQry = "SELECT branchID FROM user_branch WHERE userID IN(?) ";
String brQ = "SELECT branchName FROM branches WHERE branchID IN(%s) ";
pstmt = con.prepareStatement(userBrQry);
pstmt.setString(1, assignUserID.getText());
results = pstmt.executeQuery();
results.last();
int nRows = results.getRow();
results.beforeFirst();
while (results.next()) {
String branchIDS = results.getString("branchID");
StringBuilder builder = new StringBuilder();
for (int i = 0; i < nRows; i++) {
builder.append("?");
if (i + 1 < nRows) {
builder.append(",");
}
}
brQ = String.format(brQ, builder.toString());
PreparedStatement ps = con.prepareStatement(brQ);
for (int i = 0; i < nRows; i++) {
ps.setString(i + 1, branchIDS);
}
ResultSet rs = ps.executeQuery();
//branchJTable.setModel(DbUtils.resultSetToTableModel(rs));
javax.swing.table.DefaultTableModel model = new javax.swing.table.DefaultTableModel();
model.setColumnIdentifiers(new String[]{"Branch Name"});
branchJTable.setModel(model);
while (rs.next()) {
String branchname = rs.getString("branchName");
model.addRow(new Object[]{branchname});
}
}
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e);
}
Forget about the first 3 rows as it is a another JTable event i use to get the userID to use as a condition for getting a particular user's branches assigned to him.
The branches assigned to a user is dynamic hence using StringBuilder.
I am supposed to display the results into another JTable called branchJTable which only displays the last row.Any HELP would be appreciated!

From your question, I think you should declare the JTable
javax.swing.table.DefaultTableModel model = new javax.swing.table.DefaultTableModel();
model.setColumnIdentifiers(new String[]{"Branch Name"});
branchJTable.setModel(model);
before your first loop -
i.e. before while (results.next()) { in your code.
Otherwise in loop, for each loop execution,
the JTable Model is initialising and you are getting the last inserted row in Jtable.

How to fetch entire row as array of objects with JDBC

I have to make a 'query' method for my class which accesses MySQL thru' JDBC.
The input parameter to the method is a full SQL command (with values included), so I don't know the names of columns to fetch out.
Some of the columns are strings, some others are integers, etc.
The method needs to return the value of type ArrayList<HashMap<String,Object>>
where each HashMap is 1 row, and the ArrayList contains all rows of result.
I'm thinking of using ResultSet.getMetaData().getColumnCount() to get the number of columns then fetch cell by cell out of the current row, but is this the only solution? any better ones?

I have the example code here, just in case anybody need it. ('Con' in the code is the standard JDBC connection).
//query a full sql command
public static ArrayList<HashMap<String,Object>>
rawQuery(String fullCommand) {
try {
//create statement
Statement stm = null;
stm = con.createStatement();
//query
ResultSet result = null;
boolean returningRows = stm.execute(fullCommand);
if (returningRows)
result = stm.getResultSet();
else
return new ArrayList<HashMap<String,Object>>();
//get metadata
ResultSetMetaData meta = null;
meta = result.getMetaData();
//get column names
int colCount = meta.getColumnCount();
ArrayList<String> cols = new ArrayList<String>();
for (int index=1; index<=Col_Count; index++)
cols.add(meta.getColumnName(index));
//fetch out rows
ArrayList<HashMap<String,Object>> rows =
new ArrayList<HashMap<String,Object>>();
while (result.next()) {
HashMap<String,Object> row = new HashMap<String,Object>();
for (String colName:cols) {
Object val = Result.getObject(colName);
row.put(colName,val);
}
rows.add(row);
}
//close statement
stm.close();
//pass back rows
return tows;
}
catch (Exception ex) {
System.out.print(ex.getMessage());
return new ArrayList<HashMap<String,Object>>();
}
}//raw_query
