The NASPELL option controls the spelling that is used for NA
values in output.
Data type
TEXT
Syntax
NASPELL = {'text'|'NA'}
Arguments
The spelling to use for any NA
value in output. When you specify an expression rather than a text literal, you can omit the single quotes. The default is NA
.
Notes
Setting NASPELL to "0"
Setting NASPELL to the text character 0
(zero) causes NA
values to appear as 0
. However, they are still treated as NAs in calculations.
Assigning NA Values
NASPELL affects only Oracle OLAP output; it does not affect the way you assign an NA
value. For example, even when you have set NASPELL to NONE, you assign an NA
value as follows.
var1 = NA
$NATRIGGER Takes Precedence over NASPELL
Oracle OLAP evaluates an $NATRIGGER property expression before applying the NASPELL option. When the $NATRIGGER expression is NA
, then the NASPELL option has an effect.
Examples
Example 20-17 Showing NA Values as "NONE"
Suppose you have a variable called current.month
, which has a value of NA
whenever no current month has been specified. In this case, you would like the value to appear as None
rather than NA
.
When NASPELL is set to its default value of NA
, the OLAP DML statement
SHOW current.month
produces the following output.
NA
In contrast, the OLAP DML statements
NASPELL = 'None' SHOW current.month
produce the following output.
None
