Drop

The DROP directive is used to drop a column in a record.

Syntax

drop <column>[,<column>]*

The <column> is the name of the column in the record to be droped.

Usage Notes

After the DROP directive is applied, the column and its associated value are removed from the record. Later directives will not be able to reference the dropped column.

Example

Using this record as an example:

{
  "id": 1,
  "timestamp": 1234434343,
  "measurement": 10.45,
  "isvalid": true
}

Applying this directive:

drop isvalid,measurement

would result in a record with no isvalid or measurement fields:

{
  "id": 1,
  "timestamp": 1234434343
}
