GQL query help - How can I write a query with where clause in GQL ? I am using google appengine datastore

问题

I have three records in a table example:

*Usernames*        *email*                *city*
Nick            nick@example.com        London
Vikky           vicky@example.com       Paris
Lisa            lisa@example.com        Sydney

Now I want to get specific record keeping email ID as a key ,

SQL query may be like this

select * from table1 where email = "vicky@example.com" 

What is the equivalent GQL query for the above ??

回答1:

SELECT * FROM table1 WHERE email = 'vicky@example.com' 

should work fine in GQL.
