CrosstabMax
660 InfoMaker
CrosstabMax
Description Calculates the maximum value returned by an expression in the values list of
the crosstab. When the crosstab definition has more than one column,
CrosstabMax can also calculate the maximum of the expression’s values for
groups of column values.
For crosstabs only
You can use this function only in a crosstab report.
Syntax CrosstabMax ( n {, column, groupvalue } )
Return value
Double. Returns the maximum value returned by expression n for all the
column values or, optionally, for a subset of column values. To return a decimal
datatype, use
CrosstabMaxDec.
Usage This function is meaningful only for the maximum of the values of the
expression in a row in the crosstab. This means you can use it only in the detail
band, not in a header, trailer, or summary band.
Null values are ignored and are not included in the comparison.
For more information about restricting the calculation to groups of values when
the crosstab definition has more than one column, see Usage for CrosstabAvg.
Reviewing the expressions
To review the expressions defined for the crosstab values, open the Crosstab
Definition dialog box (select Design>Crosstab from the menubar).
Argument Description
n The number of the crosstab-values expression for which you want
the maximum returned value. The expression’s datatype must be
numeric.
column
(optional)
The number of the crosstab column as it is listed in the Columns box
of the Crosstab Definition dialog box for which you want
intermediate calculations.
groupvalue
(optional)
A string whose value controls the grouping for the calculation.
Groupvalue is usually a value from another column in the crosstab.
To specify the current column value in a dynamic crosstab, rather
than a specific value, specify @ plus the column name as a quoted
string.
