Teradata Vantage™ is our flagship analytic platform offering, which evolved from our industry-leading Teradata® Database. Until references in content are updated to reflect this change, the term Teradata Database is synonymous with Teradata Vantage.

This document describes SQL functions, methods, macros, and procedures useful for database administrators. These functions give you the ability to do the following:
  • Compress and uncompress data
  • Manage the amount of data exported to client applications
  • Find information on specific data blocks and see how often objects on specific AMPs are accessed
  • Use maps to optimize the placement of tables across AMPs or redistribute table rows after a system expansion
  • Use Teradata-created UDFs and UDTs
  • Install, replace, redistribute, and remove script files
  • Use table operators to do these things:
    • Manipulate tables
    • Run scripts to convert DBQL data to JSON
    • Run Linux and R programs inside the database
