To that end, there are still differences between our Datastore API and Google's-these differences are documented below.

1,52c1 < In addition to passing query objects to %find()%, the Mongo database allows you to specify criteria for a query operation in your programming language. < < For example: < <

< db.myCollection.find( { $where: expr } );
<

< < where ''expr'' is a string containing a JavaScript expression that returns true if the object matches. As a more convenient notation, one may simply write < <

< db.myCollection.find( expr );
<

< < Within the $where expression, we can refer to the current object under consideration as %this%. The following statements yield the same result: <

< db.myCollection.find( { a : $gt(3) } );
< db.myCollection.find( { $where: "this.a > 3" } );
<

< < The first statement is the preferred form. It will be at least slightly faster to execute because it does not require a full unmarshalling of the object. Also, the query optimizer can interpret queries in "query object" format much better than a code query. < < You may mix data-style find conditions and a function. This can be advantageous for performance because the data-style expression will be evaluated first, and if not matched, no further evaluation is required. Additionally, the database can then consider using an index for that condition's field. For example: < <

< db.myCollection.find( { active: true, $where: "this.credits - this.debits < 0" } );
<

< < ==References to Variables== < < If your $where function references a variable in global scope, that variable (and objects it references) will be transferred along with the function. For the following example, the object referenced by %z% is passed to the server along with the code of the $where function: <

< z = { a : 3, b : 4, c : someObject };
< ...
< db.myCollection.find( "this.a == z.a" );
<

< < If z were to reference huge amounts of data, performance of the query would be impaired. This is not hard to work around; suppose z.c above, which references, someObject, is very large and we do not want it passed. Instead we can write: <

< z = { a : 3, b : 4, c : someObject };
< ...
< var temp = z.a;
< db.myCollection.find( "this.a == temp" );
<

< < ==Restrictions== < < Do not write to the collection being inspected from the $where expression. < < ==More Information== < < * [[pub.db.server_side_code|Running Code in the Database]] --- > sandbox
