データ型マッピング
Data Type Mappings
The 本製品 maps types from the data source to the corresponding data type available in the schema. The table below documents these mappings.
Note: In Snowflake, the type fetched can differ from the type used to create a field. Set SessionParameters to JDBC_TREAT_DECIMAL_AS_INT=false to map INT types to DECIMAL and avoid this behavior.
