db.system.js.save
(
{
_id:"yourStoredProcedueName",
value:function(argument1,....N)
{
statement1,
.
.
N
}
}
);Now implement the above syntax. The query to create a stored procedure is as follows −
> db.system.js.save
(
{
_id:"addTwoValue",
value:function(a,b)
{
return a+b
}
}
);The following is the output −
WriteResult({ "nMatched" : 0, "nUpserted" : 1, "nModified" : 0, "_id" : "addTwoValue" })Now you can call the stored procedure using eval(). The query is as follows −
