The length of a query output alias must not exceed 25 characters. For example, this alias causes an error:
SELECT * FROM KMeans (
ON (SELECT * FROM kmeansample) as InputTable
USING
OutputTable ('kmeanssample_centroid')
NumberK ('3')
Threshold ('0.01')
MaxIterNum ('10')
) AS Long_Function_Name_Alias_Example;
The name of an output table (for example, kmeanssample_centroid in the preceding query) must not have an embedded double quote or an embedded period.
