public void getDatabaseConnectionExample(){
    //get OIM Client

    try{
        //Establish connection to OIM Schema
        XLClientSecurityAssociation.setClientHandle(oimClient);
        dbProvider = new com.thortech.xl.client.dataobj.tcDataBaseClient();

        String query = "select usr_login from usr";           
        com.thortech.xl.dataaccess.tcDataSet usersDataSet = new com.thortech.xl.dataaccess.tcDataSet();
        usersDataSet.setQuery(dbProvider, query);

        int numRecords = usersDataSet.getTotalRowCount();
