Hints Rules and Guidelines

Use the following rules and guidelines when you configure hints for SQL queries:
  • If you enable pushdown optimization or if you use a semi-join in a relational data object, then the original source query changes. The Data Integration Service does not apply hints to the modified query.
  • You can combine hints with join and filter overrides, but if you configure a SQL override, the SQL override takes precedence and the Data Integration Service does not apply the other overrides.
  • The
    Query
    view shows a simple view or an advanced view. If you enter a hint with a filter, sort, or join override on the simple view, and you the Developer tool shows the full query override on the advanced view.
