Hi,

Are you sure that myTable only contains one field (CATEGORY_NAME)? And is it VARCHAR?

conn = getConnbyDM();
String sSQL = "INSERT INTO myTable (CATEGORY_NAME)  VALUES (?)";
prepStat = conn.prepareStatement(sSQL);
prepStat.setString(1,cm.getCategoryName());
int i=prepStat.executeUpdate();

try the above program and as such prepStat = conn.prepareStatement(sSQL); was there twice in your previous program.
