SQL Transformation

SQL Transformation

The SQL transformation processes two SQL statements midstream in the mapping. The transformation retrieves a sequence number from a table and returns it in an output port. The SQL transformation increments the sequence number in the database table.
The Sequence_Number table contains the sequence number that the Data Integration Service applies to each customer order. The Sequence_Number table is in an Oracle database. The sequence number becomes the company order number in the logical data object.
Configure the following properties in the SQL transformation views:
  • Advanced Properties. Configure the database type. The column datatypes depend on what database type you choose.
  • Ports. Define the pass-through ports and the output port that receives the order number from the Sequence_Number table.
  • SQL. Define the SQL query to retrieve the sequence number and to increment the number in the database table.
  • Runtime. Choose a connection to the database that contains the sequence numbers.
