In this post I am going to explain how to Specify Equality Condition from Mongo DB collection . for this as a sample data you have to upload data into mongo db database.
Thank You !!!
db.inventory.insertMany([
{ item: "journal", qty: 25, size: { h: 14, w: 21, uom: "cm" }, status: "A" },
{ item: "notebook", qty: 50, size: { h: 8.5, w: 11, uom: "in" }, status: "A" },
{ item: "paper", qty: 100, size: { h: 8.5, w: 11, uom: "in" }, status: "D" },
{ item: "planner", qty: 75, size: { h: 22.85, w: 30, uom: "cm" }, status: "D" },
{ item: "postcard", qty: 45, size: { h: 10, w: 15.25, uom: "cm" }, status: "A" }
]);
To specify equality conditions, use <field>:<value> expressions in the query filter document:
Then you can execute below query.
db.inventory.find({ status: "D"})Above selection command is identical to
SELECT * FROM inventory WHERE status = 'D';in the SQL
Thank You !!!
