SQL语句 cursor.execute()使用占位符"%s",而不是直接在SQL中添加参数。如果您使用这种技
def GetList(request):
from .conn_mysql import transaction,connections
with connections['test'].cursor() as c:
c.execute("select * from duanzi WHERE id=%s;",[2])
# cursor.execute("select * from duanzi",[])
# cursor.execute("insert into duanzi(content,createtime) VALUES ('aa','1518186153')",[])
# transaction.commit_unless_managed()
row=c.fetchone()
# transaction.set_dirty()
# cursor.close()
return HttpResponse(row)
