3.3.7 Substring

The substring virtual column allows you to access either part of a column or a complete table record. For a substring virtual, you will need to specify the column from which you want to substring. A substring virtual can be based on:

  • a real column in the table
  • another virtual column in the table
  • the complete record contents of the table (indicated by *RECORD).
