SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL is ANSI SQL:2011-compliant with extensions.

ANSI SQL does not support the abbreviations RU and SR. They are Teradata extensions.

Other SQL dialects support similar non-ANSI standard statements with names such as the following.

  • SET CURRENT ISOLATION
  • SET ISOLATION
  • SET TRANSACTION
  • SET SESSION CHARACTERISTICS

Although SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL is technically a DCL statement, Teradata Database treats it as a DDL statement for transaction semantics.
