Rules and Guidelines for Sqoop Queries

Rules and Guidelines for Sqoop Queries

Consider the following rules and guidelines when you configure a Sqoop query in a mapping:
  • To override the default query in a mapping with an advanced query, you must define a mapping parameter with the name as
    and set its value to
    . You must then include
    in the WHERE clause of the custom query. For more information about configuring the custom query, see the following Informatica Knowledge Base article: KB 564550
  • If you define a custom query, you must verify that the metadata of the custom query matches the metadata of the source object. Otherwise, Sqoop might write blank values to the target.
  • When you enable OraOop and configure an advanced query to read data from an Oracle source through Sqoop, the mapping fails on the Spark engine.
