OPTIMIZE FOR 1 ROW tells DB2 to select an access path that returns the first qualifying row quickly. This means that whenever possible, DB2 avoids any access path that involves a sort. If you specify a value for n that is anything but 1, DB2 chooses an access path based on cost, and you won’t necessarily avoid sorts.

At the top of the page is a link to "IBM Manuals". Among these are several sets of db2 reference manuals.

In DB2, you can specify the isolation level clause in a SELECT statement: DB2 : -- Uncommitted read (mostly used to avoid read locks) SELECT name FROM cities WITH UR; -- Cursor stability (read committed) SELECT name FROM cities WITH CS; Oracle does not allow reading uncommitted rows and WITH UR clause should be removed from the SELECT statement.

OPTIMIZE FOR 1 ROW tells DB2 to select an access path that returns the first qualifying row quickly. This means that whenever possible, DB2 avoids any access path that involves a sort. If you specify a value for n that is anything but 1, DB2 chooses an access path based on cost, and you won’t necessarily avoid sorts. DB2 Cursor builds a results table to hold all the rows retrieved by executing a SELECT statement. DB2 uses a cursor to make the rows, from the results table, available to the application program.
