What happens with the output of MySQL EXPORT_SET() function if I will skip both 4th and 5th argument i.e. separator and number of bits?

As we know that the default value of the fifth argument i.e. number of bits is 64, hence if we will not specify any value on fifth argument them MySQL will check the bits up to 64 bits and produce the result. Whereas, on skipping the fourth argument i.e. separator, MySQL will use a comma (,) as a separator while displaying the output.

Example

mysql> SELECT EXPORT_SET(8,'Y','N')\G
*************************** 1. row ***************************
EXPORT_SET(8,'Y','N'): N,N,N,Y,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N,N
