Teradata Vantage™

One or more sessions could be in a delayed state waiting for rows to be inserted at the time you populate an unpopulated queue table. Without regard to fairness, Vantage reinstates 1 or more of those delayed sessions, up to the number of rows inserted into the table, to enable them to continue their consume mode requests.

Session Mode Use the following after any INSERT statements to make those rows visible to any delayed sessions
ANSI COMMIT
Teradata
  • SEMICOLON character (implicit transaction)
  • END TRANSACTION statement terminated with a SEMICOLON character (explicit transaction)
