The ANY function returns YES
when any values of a Boolean expression are TRUE
, or NO
when none of the values of the expression are TRUE
.
Return Value
BOOLEAN.
Syntax
ANY(boolean-expression [[STATUS] dimensions])
Arguments
The Boolean expression to be evaluated
Can be specified when one or more of the dimensions of the result of the function are not dimensions of the Boolean expression. (See the description of the dimensions argument.) When you specify the STATUS keyword when this is not the case, Oracle OLAP produces an error.
In cases where one or more of the dimensions of the result of the function are not dimensions of the Boolean expression, the STATUS keyword might be required in order for Oracle OLAP to process the function successfully, or the STATUS keyword might provide a performance enhancement. See "The STATUS Keyword".
The dimensions of the result. By default, ANY returns a single YES
or NO
value. When you indicate one or more dimensions for the result, ANY tests for TRUE
values along the dimensions that are specified and returns an array of values. Each dimension must be either a dimension of boolean-expression or related to one of its dimensions. When it is a related dimension, you can specify the name of the relation instead of the dimension name. This makes it possible for you to choose which relation is used when there is more than one.
Notes
When the Boolean expression involves an NA
value, ANY returns a YES
or NO
result when it can, as shown in Table 7-6, "Results of ANY with Boolean Expressions with NA Values".
Table 7-6 Results of ANY with Boolean Expressions with NA Values
Boolean Expression | Result |
---|---|
NA EQ NA |
YES |
NA NE NA |
NO |
NA EQ non-NA |
NO |
NA NE non-NA |
YES |
NA AND NO |
NO |
NA OR YES |
YES |
However, in cases where a YES
or NO
result would be misleading, ANY returns NA
. For example, when you test whether an NA
value is greater than a non-NA
value, ANY returns NA
.
ANY is affected by the NASKIP option. When NASKIP is set to YES
(the default), ANY ignores NA
values and returns YES
when any of the values of the expression that are not NA
are TRUE
and returns NO
when none of the values are TRUE
. When NASKIP is set to NO
, ANY returns NA
when any value of the expression is NA
. When all the values of the expression are NA
, ANY returns NA
for either setting of NASKIP.
When boolean-expression is dimensioned by a dimension with a type of DAY, WEEK, MONTH, QUARTER, or YEAR, you can specify any other dimension of this type as a related dimension. Oracle OLAP uses the implicit relation between these dimensions. To control the mapping of one of these dimension to another (for example, from weeks to months), you can define an explicit relation between the dimensions and specify the name of the relation as the dimension argument to the ANY function.
For each time period in the related dimension, Oracle OLAP tests the data values for all the source time periods that end in the target time period. This method is used regardless of which dimension has the more aggregate time periods.
When one or more of the dimensions of the result of the function are not dimensions of the Boolean expression, Oracle OLAP creates a temporary variable to use while processing the function. When you specify the STATUS keyword, Oracle OLAP uses the current status instead of the default status of the related dimensions for calculating the size of this temporary variable.
When the size of the temporary variable for the results of the function would exceed 2 gigabytes, you must specify the STATUS keyword in order for Oracle OLAP to execute the function successfully. When the dimensions of the Boolean expression are limited to a few values and are physically fragmented, you can specify the STATUS keyword to improve the performance of the function.
When you use the ANY function with the STATUS keyword in an expression that requires going outside of the status for results (for example, with the LEAD or LAG functions or with a qualified data reference), the results outside of the status will be returned as NA
.
Examples
Example 7-27 Testing for Any True Values by District
Suppose you want to find out which districts had at least one month with sales greater than $150,000 for sportswear. You use the ANY function to determine whether the Boolean expression (sales GT 150000
) is TRUE
for any month. To have the result dimensioned by district, specify district
as the second argument in the ANY function.
LIMIT product TO 'SPORTSWEAR' REPORT HEADING 'High Sales' ANY(sales GT 150000, district)
The preceding statements produce the following output.
DISTRICT High Sales -------------- ---------- Boston NO Atlanta YES Chicago NO Dallas YES Denver NO Seattle NO
Example 7-28 Testing for Any True Values by Region
You might also want to find out which regions had at least one month in which at least one district had sportswear sales greater than $150,000. Since the region
dimension is related to the district
dimension, you can specify region
instead of district
as a dimension for the results of ANY.
report heading 'High Sales' any(sales gt 150000, region)
The preceding statement produces the following output.
REGION High Sales -------------- ---------- East YES Central YES west NO
