BASEVAL

The BASEVAL function returns the values of the base dimensions of a concat dimension. When a base dimension is a concat dimension, then the values of its base dimensions are returned, also.

Return Value

The following are the rules that determine the data types of the values returned by BASEVAL:

Syntax

BASEVAL(concatdim)

Arguments

concatdim

Specifies the concat dimension for which you want the base values. The data types of the values returned depend on the data types of the base dimensions of the concat dimension.

Notes


Looping Over the Dimension

BASEVAL is dimensioned by the concatdim dimension so the function automatically loops over the dimension.

Examples

Example 8-26 Returning NTEXT Values

The following example creates two simple dimensions and a nonunique concat dimension, then gets the values of the concat dimension.

DEFINE textdim DIMENSION TEXT
DEFINE ntextdim DIMENSION NTEXT
MAINTAIN textdim ADD 'v1' 'v2'
MAINTAIN ntextdim ADD 'n1' 'n2'
DEFINE concatdim DIMENSION CONCAT(textdim ntextdim)
REPORT w 18 BASEVAL(concatdim)

The preceding statement returns the following.

CONCATDIM            BASEVAL(CONCATDIM)
-------------------- ------------------
<textdim: v1>        v1
<textdim: v2>        v2
<ntextdim: n1>       n1
<ntextdim: n2>       n2

The data type of the returned values is NTEXT. The BASEVAL function converted the v1 and v2 TEXT values into NTEXT values before returning them.

Example 8-27 Returning the Base Values of a Base Concat Dimension

This example defines the simple dimensions state and city and adds values to them. It defines a nonunique concat dimension, statecity, with state and city as the bases and then defines another nonunique concat dimension, geog, with region, district, and statecity as its bases. Finally, the REPORT statement returns the values returned by the BASEVAL function.

DEFINE city DIMENSION TEXT
DEFINE state DIMENSION TEXT
MAINTAIN city ADD 'Boston' 'Worcester' 'Portsmouth' 'Portland' -
  'Burlington' 'Hartford' 'New York' 'Albany'
MAINTAIN state ADD 'MA' 'NH' 'ME' 'VT' 'CT' 'NY'
DEFINE statecity DIMENSION CONCAT(state city)
DEFINE geog DIMENSION CONCAT(region district statecity)
LCOLWIDTH = 20
REPORT W 16 BASEVAL(geog)

The preceding statement returns the following.

GEOG                 BASEVAL(GEOG)
-------------------- ----------------
<region: East>       East
<region: Central>    Central
<region: West>       West
<district: Boston>   Boston
<district: Atlanta>  Atlanta
<district: Chicago>  Chicago
<district: Dallas>   Dallas
<district: Denver>   Denver
<district: Seattle>  Seattle
<state: MA>          MA
<state: NH>          NH
<state: ME>          ME
<state: VT>          VT
<state: CT>          CT
<state: NY>          NY
<city: Boston>       Boston
<city: Worcester>    Worcester
<city: Portsmouth>   Portsmouth
<city: Portland>     Portland
<city: Burlington>   Burlington
<city: Hartford>     Hartford
<city: New York>     New York
<city: Albany>       Albany
