How do you access the value of an SQL count () query in a Java program

Question

I want to get to the value I am finding using the COUNT command of SQL. Normally I enter the column name I want to access into the getInt() getString() method, what do I do in t

Answer 1

I have done it this way (example):

String query="SELECT count(t1.id) from t1, t2 where t1.id=t2.id and t2.email='"r@r.com"'";
int count=0;
try {
    ResultSet rs = DatabaseService.statementDataBase().executeQuery(query);
    while(rs.next())
        count=rs.getInt(1);
} catch (SQLException e) {
    e.printStackTrace();
} finally {
    //...
}
