Examples

This example successfully converts the JSON data to binary:

SELECT TRY_TO_BINARY(PARSE_JSON('{"key":"value", "number":123}')) AS binary_variant_success;

┌──────────────────────────────────────────────────────────────────────────┐
                              binary_variant

└──────────────────────────────────────────────────────────────────────────┘

This example demonstrates that the function fails to convert when the input is NULL:

SELECT TRY_TO_BINARY(PARSE_JSON(NULL)) AS binary_variant_invalid_json;

┌─────────────────────────────┐

 NULL
