Insert a collection user with record {name:”sagar”,age:26,status:”pending”}

UPDATEUPDATEUPDATEUPDATE

We can see that user collection has two record with auto generated _id field and given status as

“pending” and “approved”

Last command on MongoDB Shell shows our update statement.

We need to update user status as reject whose age is greater then 18

Similar to SQLSimilar to SQLSimilar to SQLSimilar to SQL : UPDATE user SET status=’reject’ WHERE age>18

Equivalent MongoDB Statement :Equivalent MongoDB Statement :Equivalent MongoDB Statement :Equivalent MongoDB Statement :

db.user.update({age:{$gt:18}},{$set:{status: ”reject”}})

You can see the output of update statement that modified records are 1, also the the READ commad

result that record that age>18age>18age>18age>18 (age=26age=26age=26age=26)))) is now having rejectrejectrejectreject statusstatusstatusstatus

To perform the remove command we inserted one more records with approvedapprovedapprovedapproved status, so now we have

total two record.

We can easily remove record based on WHERE conditionWe can easily remove record based on WHERE conditionWe can easily remove record based on WHERE conditionWe can easily remove record based on WHERE condition

db.user.remove({status:”approved”})
