Rules and Guidelines for Sybase IQ External Loaders

Rules and Guidelines for Sybase IQ External Loaders

Use the following rules and guidelines when you use external loaders to load to Sybase IQ:
  • Ensure that target tables do not violate primary key constraints.
  • Configure a Sybase IQ user with read/write access before you use a Sybase IQ external loader.
  • Target flat files for a Sybase IQ external loader can be fixed-width or delimited.
  • The Sybase IQ external loader cannot perform update or delete operations on targets.
  • For a session with multiple partitions, use the round-robin partition type to route data to a single target file.
  • If the Integration Service and Sybase IQ server are on different machines, map or mount a drive from the machine hosting the Integration Service to the machine hosting the Sybase IQ server.
