I'm looking at the documentation and I don't see a way to "executeScalar" -- which is what I think you're looking for.

One technique you could use is to put that stuff in a function, get the count the hard way and return it as a long. That way, you can use it (by masking it) as a direct result.

Well count any not null column in the table. Then the below code will help u.

if(resultset.next())
long count = Parse to Long (resultset.getString("columnname"));

Use Integer.parseInt() function . It takes String as parameter

use the
int getInt(int columnIndex)
Retrieves the value of the designated column in the current row of this ResultSet object as an int in the Java programming language.

method of ResultSet.
