Remove the confidence value and the SAMPLING SIZE clause from the statement.
For example, the following statement has a confidence value of 0.99:
UPDATE STATISTICS HIGH RESOLUTION 0.1 0.99;
The corrected statement is:
UPDATE STATISTICS HIGH RESOLUTION 0.1;
If you want a distribution that is based upon sampling rather than one that uses all of the data in a column, change the mode from HIGH to MEDIUM and you specify number of samples using the SAMPLING SIZE clause.
