MSCEWI2042
Table columns between tables (Teradata) DBC.COLUMNSV and INFORMATION_SCHEMA.COLUMNS (SnowFlake). But some columns might not have an exact match in Snowflake.
Severity
Low
Description
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.

Recommendations
