Django implements native SQL multi-parameterization

1. Django executes native SQL parameterization

emp_num='012'
emp_name='布瓜'
sql1 = ('select a.EMP_NUM,a.EMP_NAME from emp_data a where a.EMP_NUM="%s"'%emp_num)
print(sql1)

2. When passing parameters through sql statements, and there are multiple parameters

sql2 = ('select a.EMP_NUM,a.EMP_NAME from emp_data a where a.EMP_NUM="%s" and a.EMP_NAME="%s"'%(emp_num,emp_name))
print(sql2)
