Parameters Keyword Type Description array1 Any Type Array Array of values. array2 Any Type Array Array of values. Returns Any Type Array Examples Find the of values from two integer arrays that are not in both arrays symmetricdifference({1, 2, 3, 4}, {3, 4, 5, 6}) returns an array with 1, 2, 5, 6 Values are matched with case sensitivity symmetricdifference({"a", "b"}, {"a", "B"}) returns an array with b, B Array types must match symmetricdifference({"a", "b"}, {1, 2}) returns the following error: Invalid types, can only act on data of the same type. NOTE: Use either the conversion functions or the cast() function to convert to the appropriate type. symmetricdifference({"a", "b"}, tostring({1, 2})) returns an array with {"a", "b", "1; 2"} Every field of a CDT, dictionary, or map must match to be treated as identical: symmetricdifference({a: 1, b: 2}, {a: 1, b: 2, c: 3}) returns {{a: 1, b: 2}, {a: 1, b: 2, c: 3}} symmetricdifference({a: 1, b: 2}, {a: 1, b: 2}) returns {} Null values and empty lists Null values are included as long as they are of the correct types (nulls of an incorrect type throw a type mismatch error): symmetricdifference({"a", "b"}, {"c", ""}) returns an array with a, b, c, "" Empty lists are ignored as long as they are of the correct types (empty lists of an incorrect type throw a type mismatch error): symmetricdifference(tointeger({}), {1, 2}) returns an array with 1, 2 Scalar values Scalar values are cast to arrays with a single entry: symmetricdifference(1, {2, 3}) returns an array with 1, 2, 3 Find whether two arrays match The following example returns true if local!updatedArray matches local!originalArray, otherwise returns false: 1 2 3 4 5 6 length( symmetricdifference( local!originalArray, local!updatedArray ) ) = 0 Feature compatibility The table below lists this function's compatibility with various features in Appian. Feature Compatibility Note Portals Compatible Offline Mobile Compatible Sync-Time Custom Record Fields Compatible Can be used to create a custom record field that only evaluates at sync time. Real-Time Custom Record Fields Incompatible Custom record fields that evaluate in real time must be configured using one or more Custom Field functions.
