二、查询变量
'''
sql='''
select * from 
t_deci_sx_cash
'''
data=pd.read_sql(sql, finan_nova_risk)#执行sql
data1=list(data['content'])#获取json串

#方法一：
q=list()
for i in range(len(data1)):
    try:
        q.append([eval(data1[i])[j] for j in variable])
    except:        
        q.append('nan')
    print(i)
his_Variable = pd.DataFrame(q, columns=variable)
