  • Any declaration (local variable, cursor, condition, or condition handler) statement
  • A cursor statement (OPEN, FETCH, or CLOSE)

A compound statement stored procedure body consists of a BEGIN-END statement enclosing a set of declarations and statements, including:

  • Local variable declarations
  • Cursor declarations
  • Condition declarations
  • Condition handler declaration statements
  • Control statements
  • SQL DML, DDL, and DCL statements supported by stored procedures, including dynamic SQL
  • Multistatement requests (including dynamic multistatement requests) delimited by the keywords BEGIN REQUEST and END REQUEST

Compound statements can also be nested.
