Syntax
SetNumber( INPUT index AS INTEGER,
INPUT value AS CHARACTER )
|
-
index
- An INTEGER that identifies the element in the array to change. Indexing
into JsonArrays is 1-based.
A JsonError is raised if index is
less than 1, is greater than the length of the JsonArray, or is
the Unknown value (?).
-
value
- A CHARACTER expression representing a numeric value to which the
new property is to be set. The value should match the pattern for
valid JSON number values. These may be integers ([-]dddd), decimals ([-]ddd.ddd),
or scientific notation ([-]ddd[.ddd]e[+|-]ddd). If value is
the Unknown value (?), the element is set to the JSON
null value. If the value is not a valid JSON number value or is
an empty string (""), a JsonError is raised.
