BLOB in alias table (Deprecated)

The BLOB in alias table format maps a Service Manager array field as a binary large object (BLOB) within an alias table. This array format is deprecated. In earlier versions, this format was intended to support the following features:

  • Your RDBMS vendor could only support one "long" data type per table (This is still a restriction on Oracle databases but can be worked around by using CLOB and BLOB data types instead.)
  • You want the option to store very large array elements
  • You want to support complex arrays of structure
  • You do not need to use third-party tools to run reports against your array data

You should use one of the following array formats instead of the BLOB in alias table format.

  • Field in main table
  • BLOB in main table
  • Multi-row array table
