The maximum number of fields in a record format is 8000. If any of the fields in the record format are
date, time, timestamp, variable length, or allows the null value, then the actual maximum number of fields
can be less than 8000. The maximum number of fields can vary depending on the number of fields and
combinations of fields that occur within the record format. The maximum number of bytes in a record
format is 32 766 if variable length fields are not included and 32 740 if variable length fields are included.

2的18次方=262，2的19次方=524，288
