The ACROSS command specifies a text expression that contains one or more statements to be executed in a loop. ACROSS temporarily sets status to the values that are in current status for the specified dimensions. After the ACROSS statement executes, dimension status is restored to what it was before the loop, and execution of the program resumes with the next statement. The repetition of the statements in the DO clause statements is controlled by the status of the dimensions and composites specified in the ACROSS statement.
ACROSS dimension... DO dml-statements
One or more dimensions or composites whose current status controls the repetition of one or more statements, which are contained in dml-statements. The statements are repeated for each combination of the values of the specified dimensions in the current status. When two or more dimensions are specified, the first one varies the slowest.
A multiline text expression that is one or more OLAP DML statements to be executed for each iteration of the loop. You can specify any OALAP DML statement except one that is typically used as part of a multiple-line construct in a program. For example, the IF...THEN...ELSE, WHILE, FOR, or SWITCH commands cannot be executed by an ACROSS statement.
Oracle OLAP does not generate the code for the loop body until an ACROSS statement or the program that contains it is executed. This allows for the possibility that, because the statements are contained within a text expression, the contents of an ACROSS loop may change between compilation and execution.
