How to convert from string to date data type in MongoDB?
To convert from String to date data type, you need to write some script. Let us first create a collection with documents
>db.stringToDateDataTypeDemo.insertOne({"CustomerName":"Carol","ShippingDate":"2019-
01-21"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5ca2071d66324ffac2a7dc60")
}
>db.stringToDateDataTypeDemo.insertOne({"CustomerName":"Bob","ShippingDate":"2019-
02-24"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5ca2073566324ffac2a7dc61")
}
>db.stringToDateDataTypeDemo.insertOne({"CustomerName":"Chris","ShippingDate":"2019-
04-01"});
{
"acknowledged" : true,
"insertedId" : ObjectId("5ca2074266324ffac2a7dc62")
}
Following is the query to display all documents from a collection with the help of find() method
> db.stringToDateDataTypeDemo.find().pretty();
This will produce the following output
{
"_id" : ObjectId("5ca2071d66324ffac2a7dc60"),
"CustomerName" : "Carol",
"ShippingDate" : "2019-01-21"
}
{
"_id" : ObjectId("5ca2073566324ffac2a7dc61"),
"CustomerName" : "Bob",
"ShippingDate" : "2019-02-24"
}
{
"_id" : ObjectId("5ca2074266324ffac2a7dc62"),
"CustomerName" : "Chris",
"ShippingDate" : "2019-04-01"
}
Following is the query to convert String to date data type
> db.stringToDateDataTypeDemo.find().forEach(function(data){
... data.ShippingDate= ISODate(data.ShippingDate);
... db.stringToDateDataTypeDemo.save(data);
... });
Let us display all documents once again to check the string is converted to date data type or not. Following is the query
> db.stringToDateDataTypeDemo.find().pretty();
This will produce the following output
{
"_id" : ObjectId("5ca2071d66324ffac2a7dc60"),
"CustomerName" : "Carol",
"ShippingDate" : ISODate("2019-01-21T00:00:00Z")
}
{
"_id" : ObjectId("5ca2073566324ffac2a7dc61"),
"CustomerName" : "Bob",
"ShippingDate" : ISODate("2019-02-24T00:00:00Z")
}
{
"_id" : ObjectId("5ca2074266324ffac2a7dc62"),
"CustomerName" : "Chris",
"ShippingDate" : ISODate("2019-04-01T00:00:00Z")
}
