ColumnName
- If more than one column or expression is specified, each column or expression is separated by a comma.
- The maximum number of columns is 64.
- If expressions are in the list, the maximum number of columns can be reduced past the limit of 64, depending on the combined total size of the text in the expressions.
- If the combined total size of the expression text causes the maximum column limit to be less than the actual number of columns in the list, an error occurs.

The FieldIdList column is NULL for fields that involve expressions.
MaxInterval and MaxValueLength
If these statistics are collected with system determined maximum intervals and maximum value length, the MaxInterval and MaxValueLength columns are NULL.
