Changing your SELECT * FROM dbo.Patients
to SELECT pIDNo AS 'Patient ID', pLName AS '....
is the easiest way. And, naming the column names instead of using *
is faster.
JTable Header format

Question
I want to change the header of my JTable
that displays the data from SQL Server database because it also display the same column name on my database. I just need the Data itself, not the column name.
here is the code that I used to display the Data:
public void search() throws Exception{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:*****";
String user = "*****";
String pass = "*****";
Connection con = DriverManager.getConnection(url, user, pass);
Statement state = con.createStatement();
ResultSet rs = state.executeQuery("SELECT * FROM dbo.Patients");
ResultSetMetaData rsmetadata = rs.getMetaData();
int columns = rsmetadata.getColumnCount();
DefaultTableModel dtm = new DefaultTableModel();
Vector column_name = new Vector();
Vector data_rows = new Vector();
for (int i=1; i<columns;i++){
column_name.addElement(rsmetadata.getColumnName(i));
}
dtm.setColumnIdentifiers(column_name);
while(rs.next()){
data_rows = new Vector();
for (int j=1; j<columns; j++){
data_rows.addElement(rs.getString(j));
}
dtm.addRow(data_rows);
}
tblPatient.setModel(dtm);
}
and this is the result :
I want to change that pIDNo to Patient ID, pLName to Last Name, pFName to First Name, so on and so forth...

Autres conseils
I'd try to modify your select:
instead
SELECT * FROM dbo.Patients
Use
SELECT pId as "Patient ID", ...
