Python的GQL查询不能

Question

ID = int(data_key) 
    results = db.GqlQuery("SELECT * FROM PatientMeds WHERE patientinfo_ID='ID'") 

在那里我有做错了......

谢谢..

Answer 1

使用的参数（实例1，2）：

ID = int(data_key) 
results = db.GqlQuery("SELECT * FROM PatientMeds WHERE patientinfo_ID=:1", ID) 
# or 
results = db.GqlQuery("SELECT * FROM PatientMeds WHERE patientinfo_ID=:id", id=ID) 

Answer 2

你也可以使用更多“Pythonic”型号API：

from path.to.your.models import PatientMeds 
results = PatientMeds.all().filter('patientinfo_ID =', int(data_key))
