Variant column does not support collation.
This message is shown when SnowConvert a Variant data type in the transformation of a code has a COLLATE clause. Since COLLATE is not supported with the data type VARIANT, it will be removed and a message will be added.
CREATE TABLE TableExample
ColumnExample JSON(2500) NOT CASESPECIFIC
CREATE TABLE PUBLIC.TableExample
ColumnExample VARIANT /*** MSC-WARNING - MSCEWI2018 - VARIANT COLUMN DOES NOT SUPPORT COLLATION ***/
The data type JSON is converted to VARIANT, while NOT CASESPECIFIC is converted to a COLLATE clause.
Because if this scenario, since VARIANT does not support COLLATE, it is removed.
