21.39 WRITE Procedure Signature 6
This procedure writes an array attribute of type sys.xmltype
. The procedure uses a XSL transformation to generate JSON. To determine the JSON type of values, it uses the following rules:
-
If the value is empty, it generates a
NULL
value. -
If upper(value) is
TRUE
, it generates a boolean true value. -
If upper(value) is
FALSE
, it generates a boolean false value. -
If the
XPath
number function returnsTRUE
, it emits the value as is. Otherwise, it enquotes the value (that is, treats it as a JSON string).
Syntax
APEX_JSON.WRITE (
p_value IN sys.xmltype );
