pack_all()

Creates a dynamic object (property bag) from all the columns of the tabular expression.

Note

The representation of the returned object isn't guaranteed to be byte-level-compatible between runs. For example, properties that appear in the bag may appear in a different order.

Syntax

pack_all([ignore_null_empty])

Arguments

• ignore_null_empty: An optional bool indicating whether to ignore null/empty columns and exclude them from the resulting property bag. Default: false.

Examples

Given a table SmsMessages

SourceNumber	TargetNumber	CharsCount
555-555-1234	555-555-1212	46
555-555-1234	555-555-1213	50
555-555-1313		42
	555-555-3456	74

The following query:

datatable(SourceNumber:string,TargetNumber:string,CharsCount:long)
[
'555-555-1234','555-555-1212',46,
'555-555-1234','555-555-1213',50,
'555-555-1313','',42, 
'','555-555-3456',74 
]
| extend Packed=pack_all(), PackedIgnoreNullEmpty=pack_all(true)

Returns:

SourceNumber	TargetNumber	CharsCount	Packed	PackedIgnoreNullEmpty
555-555-1234	555-555-1212	46	{"SourceNumber":"555-555-1234", "TargetNumber":"555-555-1212", "CharsCount": 46}	{"SourceNumber":"555-555-1234", "TargetNumber":"555-555-1212", "CharsCount": 46}
555-555-1234	555-555-1213	50	{"SourceNumber":"555-555-1234", "TargetNumber":"555-555-1213", "CharsCount": 50}	{"SourceNumber":"555-555-1234", "TargetNumber":"555-555-1213", "CharsCount": 50}
555-555-1313		42	{"SourceNumber":"555-555-1313", "TargetNumber":"", "CharsCount": 42}	{"SourceNumber":"555-555-1313", "CharsCount": 42}
	555-555-3456	74	{"SourceNumber":"", "TargetNumber":"555-555-3456", "CharsCount": 74}	{"TargetNumber":"555-555-3456", "CharsCount": 74}

Note

There is a difference between the Packed and the PackedIgnoreNullEmpty columns in the last two rows of the above example. These two rows included empty values that were ignored by pack_all(true).
