Supported IBM Db2 on Cloud data types
Last updated: Feb 25, 2025
When you use IBM Db2 on Cloud as a source connection, you can replicate only some data types.
When you use the Db2 on Cloud connection with the Copy goal, Data Replication will attempt to create or replicate to a column in the target database with a similar column name and compatible data type. If the data type of the
target column is not compatible, it will convert the target data type to a string-based data type (for example, varchar
The following table shows the Db2 on Cloud data types that you can replicate. If a source table contains a column with an unsupported data type, the table is not replicated to the target database.
