Hi,
I think this code might help u out.
for(int i=0;i<table.getRowCount();i++) { //table is the name of ur JTable
String sbValues = "insert into table values(";//table is the name of the table in the database where data is to be inserted
String sbData = "";
for(int j=0;j<table.getColumnCount();j++) {
String s2 =(String)table.getValueAt(i,j);
if(s2==null)
s2 = "";
sbValues+=s2+",";
}
sbData+=sbValues.substring(0,sbValues.length()-1)+")";
statement.executeUpdate(sbData); //statement is ur statement object.
}
