ARGS

Within an OLAP DML program, the ARGS function lets you reference the arguments that are passed to a program. The function returns all the arguments as a single text value. You can use the ARGS function only within a program that is be invoked as a command, not as a user-defined function or with a CALL statement.

Note:

Typically, programmers use an ARGUMENT statement to define arguments in a program, thereby negating the need for using the ARGS function to reference arguments passed to the program. For more information on how to use ARGUMENT to define arguments that are passed to a program, see "Declaring Arguments that Are Passed Into a Program" .

Return Value

TEXT

When no arguments have been specified for the program, ARGS returns a null value

Examples

Example 7-23 Passing Arguments Using ARGS

Assume you have a program that produces a simple sales report. You want to be able to produce this report for any month, so you do not want to limit the month dimension to any fixed month in the program. You can use the ARGS function in your LIMIT command so that the months for the report can be supplied as an argument when the program is run.

When ARGS is included in the LIMIT command preceded by an ampersand (&), Oracle OLAP substitutes the values of &ARGS before the command is executed and, consequently, treats the whole argument as a phrase of the LIMIT command. The salesreport program has a LIMIT command that includes &ARGS.

DEFINE salesrpt PROGRAM
PROGRAM
PUSH month product district
TRAP ON cleanup 
LIMIT month TO &ARGS
LIMIT product TO 'CANOES'
LIMIT district TO ALL
REPORT grandtotals DOWN district sales
cleanup:
POP month product district
END

When you execute the following statement, the LIMIT command uses the values Jan96 and Feb96 for the month dimension.

salesrpt 'Jan96' 'Feb96'

The statement produces the following output.

PRODUCT: CANOES
       --------SALES--------
       --------MONTH--------
DISTRICT       Jan96      Feb96
