You need to create 2 linked services for Oracle and Synapse and configure the connection properties (server name, database name, username, password...).
Next, create datasets referencing the tables in the Oracle and Synapse databases where you specify the table or use a query to define the dataset.
Then, you can use Data Flows to perform the following :
- Add a source transformation to read data from the Synapse table dataset.
- Add a Join transformation to join the data from the Synapse table with the Oracle table.
- Add an Alter Row transformation to specify the update conditions to determine which rows should be updated in the Oracle table.
- Add a Sink transformation to return the updated data to the Oracle table.
- Configure the Sink to perform an update operation. You can use the Upsert setting if applicable.
