Uses of the table
DBC.COLUMNSV in Teradata are converted to
INFORMATION_SCHEMA.COLUMNS, but some columns might not have an exact match in SnowFlake. That means there are some columns in Teradata for which there is no equivalent in SnowFlake, and there are others that do have a matching column but the content is not exactly the same.
Notice, for example, that there is no equivalent column for "ColumnFormat" in SnowFlake and notice also that "DATA_TYPE" seems to be the match for the column "ColumnType" in Teradata, but their content greatly differ.
SELECT columnname FROM dbc.columnsV WHERE tablename = 'TableN';

Review what columns were used in Teradata and check if the available content in SnowFlake matches your needs.
