Fill NULL or Empty directive
The FILL-NULL-OR-EMPTY directive fills column value with a fixed value if it is either null or empty ("").
Syntax
fill-null-or-empty :column 'value'If the
columndoes not exist, then the directive will fail.The
valuecan only be of type string.
Usage Notes
The FILL-NULL-OR-EMPTY directive fills the column value with the value if the column value is null or empty (an empty string, "").
The value must be a string and cannot be an empty string value.
When the object in the record is a JSON object and it is null, the directive checks that it is also applied to those records.

{
"id": 1,
"fname": "root",
"mname": null,
"lname": "joltie",
"address": ""
}Applying these directives:
fill-null-or-empty :mname 'NA'
fill-null-or-empty :address 'No address specified'results in this record:
{
"id": 1,
"fname": "root",
"mname": "NA",
"lname": "joltie",
"address": "No address specified"
}
