Specifications
Count
652 InfoMaker
Usage If you specify range, Count determines the number of rows in column in range.
If you specify DISTINCT,
Count returns the number of the distinct rows
displayed in column, or if you specify expresn, the number of rows displayed
in column where the value of expresn is distinct.
For graphs and OLE objects, you do not select the range when you call the
function. The range has already been determined by the Rows setting on the
Data property page (the Range property), and the aggregation function uses
that range.
Settings for Rows include the following:
• For the Graph presentation style, Rows is always All.
• For Graph controls, Rows can be All, Page, or Group.
• For OLE controls, Rows can be All, Current Row, Page, or Group. The
available choices depend on the layer the control occupies.
Null values in the column are ignored and are not included in the count.
FOR range
(optional)
The data that will be included in the count. For most presentation
styles, values for range are:
• ALL – (Default) The count of all rows in column.
• GROUP n – The count of rows in column in the specified group.
Specify the keyword GROUP followed by the group number: for
example, GROUP 1.
• PAGE – The count of the rows in column on a page.
For Crosstabs, specify CROSSTAB for range:
• CROSSTAB – (Crosstabs only) The count of all rows in column
in the crosstab.
For Graph and OLE objects, specify one of the following:
• GRAPH – (Graphs only) The count of values in column in the
range specified for the Rows option.
• OBJECT – (OLE objects only) The count of values in column in
the range specified for the Rows option.
DISTINCT
(optional)
Causes
Count to consider only the distinct values in column when
counting the rows. For a value of column, the first row found with
the value is used and other rows that have the same value are
ignored.
expresn
(optional)
One or more expressions that you want to evaluate to determine
distinct rows. Expresn can be the name of a column, a function, or
an expression.
