Google App Engine GQL queries in the Datastore Viewer console

I’m forever having to look up various types of obscure GQL syntax to use in the App Engine console. I thought I’d start a blog post where I note them down, for my own sake. I’ll update this as I go.

Look up entities by encoded key string

SELECT * FROM EntityName WHERE __key__ IS KEY('dkfjbILVUYFkfbaelIIUBkuafvKJ')

Look up child entities by encoded key string

SELECT * FROM EntityName WHERE ancestor IS KEY('dkfjbILVUYFkfbaelIIUBkuafvKJ')

More to come, if you find one I’m missing let me know
