Anonymous Blocks

An anonymous block applies to a script infrequently executed or a one-off activity. An anonymous block is executed in a session and is not stored.

Syntax

Figure 1 shows the syntax diagrams for an anonymous block.

Figure 1 anonymous_block::=

Details about the syntax diagram are as follows:

  • The execute part of an anonymous block starts with a BEGIN statement, has a break with an END statement, and ends with a semicolon (;). Type a slash (/) and press Enter to execute the statement.

    The terminator "/" must be written in an independent row.

  • The declaration section includes the variable definition, type, and cursor definition.
  • A simplest anonymous block does not execute any commands. At least one statement, even a NULL statement, must be presented in any implementation blocks.
