Error Message Reporting bytea
If you specify a BYTE or VARBYTE value for a function syntax element for which that type is incompatible, you get this error message:
function_name: The column 'column_name' specified in syntax_element_name must be a member of one of the following SQL type groups: [INTEGER, STRING]. Found: bytea
Error Message Reporting Incorrect DISTRIBUTIONTYPE
Some ML Engine functions create temporary tables for internal processing. In these tables, the distribution key (partition key) column depends on user-specified syntax elements. The data type of the distribution key column must belong to SQL group DISTRIBUTIONTYPE; that is, it must be a data type allowed for PARTITION KEY (see Partition Key).
