An SQL inline view is a SELECT statement in the FROM clause of another SELECT statement. For example, the following SQL includes an inline view:
SELECT ename
FROM (SELECT ename
FROM emp)
A PowerCenter Source Qualifier or Lookup transformation can include an SQL override that refers to a database table, view, or synonym in an inline view. If you create connection assignments between the relational database and PowerCenter resources, data lineage for the database table, view, or synonym displays the links between the relational database objects and the PowerCenter transformations.
SQL inline views are also referred to as Common Table Expressions.
