MongoDB find Query comparision with CurrentDate

MongoDB find Query comparision with CurrentDate

In MongoDB, you can use the $expr operator along with the $eq operator to compare a field with the current date. The $expr operator allows you to use aggregation expressions within the find method.

Here's an example of a MongoDB find query that compares a field named yourDateField with the current date:

db.yourCollection.find({
  $expr: {
    $eq: [
      { $dateToString: { format: "%Y-%m-%d", date: "$yourDateField" } },
      { $dateToString: { format: "%Y-%m-%d", date: new Date() } }
    ]
  }
})

This query uses the $dateToString operator to convert the yourDateField to a string with the format "%Y-%m-%d" (year-month-day). It then compares this string with the current date converted to the same format.

Replace yourCollection with the actual name of your collection and yourDateField with the field you want to compare with the current date.

This example assumes that the yourDateField field contains date values. If it contains date-time values, you may need to adjust the date format and include the time component in the comparison.

Adjust the format and field names based on your specific requirements and the structure of your documents.
