PACK_VALUES

Description

PACK_VALUES

is a row function that returns multiple output values packed into a single string of key/value pairs separated by the default key and pair separators. The string returned is in a format that can be read by the

EXTRACT_VALUE

function.

PACK_VALUES

uses the same key and pair separator values that

EXTRACT_VALUE

uses (the Unicode escape sequences

u0003

and

u0002

, respectively).

Syntax

PACK_VALUES

(

key

value

key

value

][,...])

Return Value

Returns one value per row of type

TEXT

. If the value for either

key

value

of a pair is null or contains either of the separator values, the full key/value pair is omitted from the return value.

The key separator is

u0003

, which is the Unicode escape sequence for the

start of text

character. The pair separator is

u0002

, which is the Unicode escape sequence for the

end of text

character.

Input Parameters

key: At least one required. A field name of any type, a literal string or number, or an expression that returns any value.
value: At least one required. A field name of any type, a literal string or number, or an expression that returns any value. The expression must include one
value
instance for each
key
instance.

Examples

Combine the values of the [custid] and [age] fields into a single text field.

PACK_VALUES("ID", [custid], "Age", [age])

This expression returns

ID
\u0003
5555
\u0002
Age
\u0003
29

when the value of the [custid] field is 5555 and the value of the [age] field is 29:

PACK_VALUES("ID", [custid], "Age", [age])

This expression returns

Age
\u0003
29

when the value of the [age] field is 29:

PACK_VALUES("ID", NULL, "Age", [age])

This expression returns

as a

Text

value when the [age] field is an

INTEGER

and its value is 29:

EXTRACT_VALUE(PACK_VALUES("ID", [custid], "Age", [age]), "Age")
