Java拼接批量新增SQL语句

StringBuffer addsql = new StringBuffer(1000);
            int batchSize = 50;
            int executeTime = 0;
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"for (int i=0; i<trackIds.size(); i++) {
                if(i/batchSize > executeTime) {//50轮执行一次sql（拷贝数据量太大）
                    String sql = addsql.substring(0,addsql.length() - 1);
                    baseJdbcDao.exceute(sql,null);
                    executeTime++;执行次数++
                }
                if(i%batchSize == 0) {50轮重新拼接sql（防止sql过长）
                    addsql = addsql.delete(0,addsql.length());
                    addsql.append("insert into " + DatabaseConstants.BASE + ".yk_behavior_monitor (TRACK_ID,PROGRAM_ID," +
