Verify the Data Type Mapping

Verify the Data Type Mapping

When you switch a connection, the Developer tool identifies the best data type match between the databases that the original connection and the new connection point to. It sets the data types for the data object and the transformations in the mapping that are based on the data object accordingly. Before you run a mapping, verify the data types and manually update them, if required.
For example, you switch a connection from Oracle to Microsoft SQL Server. For data types with a fixed precision, by default, the Developer tool sets the precision based on the precision of the Microsoft SQL Server database. However, for data types with a variable precision, the Developer tool sets the precision and scale based on the Oracle database. For data types such as Timestamp with Time Zone, the Developer tool sets the data type as Varchar (0,0) or an equivalent data type that the Microsoft SQL Server database supports for Varchar.
