BEGIN WORK

Starts a database transaction in the current connection.

Syntax

BEGIN WORK

Usage

Use the BEGIN WORK instruction to indicate where the database transaction starts in your program. Each row that an UPDATE, DELETE, or INSERT statement affects during a transaction is locked and remains locked throughout the transaction.

BEGIN WORK is part of the language syntax, the underlying database driver executes the native SQL statement corresponding to this SQL instruction.

The next code example starts a transaction block, inserts a row and updates the row, then commits the transaction. To other users, the INSERT and UPDATE instruction will be seen as an single atomic database modification:

MAIN
  DATABASE stock
  BEGIN WORK
  INSERT INTO items VALUES ( ... )
  UPDATE items SET ...
  COMMIT WORK
END MAIN
