Database sources include relational sources such as Oracle, MySQL, and Microsoft SQL Server. When you configure a Source transformation for a database source, you can use a single source table or multiple source tables. If you use multiple tables as a source, you can select related tables or create a relationship between tables.
To configure a Source transformation for a database source, perform the following tasks:
Configure the source properties.
If the source includes multiple tables, configure the Source transformation to join the tables. You can join related tables or specify a custom relationship.
Optionally, configure a custom SQL query to extract source data.
Optionally, configure the Source transformation to filter or sort source data.
Ensure that the table and column names do not exceed 74 characters.
