Calculates the mode of the values of the column. The mode is the most frequently occurring value.
Mode ( column { FOR range { DISTINCT { expres1 {, expres2 {, ... } } } } } )
Argument |
Description |
|---|---|
column |
The column for which you want the mode of the data values. Column can be the column name or the column number preceded by a pound sign (#). Column can also be an expression that includes a reference to the column. The datatype of column must be numeric. |
FOR range (optional) |
The data that will be included in the mode. For most presentation styles, values for range are:
For Crosstabs, specify CROSSTAB for range:
For Graph and OLE objects, specify one of the following:
|
DISTINCT (optional) |
Causes Mode to consider only the distinct values in column when determining the mode. 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. |
The numeric datatype of the column. Returns the mode of the values of the rows in range if it succeeds and –1 if an error occurs.
If you specify range, Mode returns the mode of column in range. If you specify DISTINCT, Mode returns the mode of the distinct values in column, or if you specify expresn, the mode of column for each distinct value of expresn.
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:
For the Graph or OLE 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.
In calculating the mode, null values are ignored.
Not in validation rules or filter expressions
You cannot use this or other aggregate functions in validation
rules or filter expressions.
Using an aggregate function cancels the effect of setting Retrieve Rows As Needed in the painter. To do the aggregation, a report always retrieves all rows.
This expression returns the mode of the values in the column named salary:
Mode(salary)
This expression returns the mode of the values for group 1 in the column named salary:
Mode(salary for group 1)
This expression returns the mode of the values in column 5 on the current page:
Mode(#5 for page)
This computed field returns Above Mode if the mode of the salary for the page is greater than the mode for the report:
If(Mode(salary for page) > Mode(salary), "Above Mode", " ")
This expression for a graph value sets the data value to the mode of the sale_price column:
Mode(sale_price)
This expression for a graph value entered on the Data page in the graph’s property sheet sets the data value to the mode of the sale_price column for the entire graph:
Mode(sale_price for graph)
Assuming a report displays the order number, amount, and line items for each order, this computed field returns the mode of the order amount for the distinct order numbers:
Mode(order_amt for all DISTINCT order_nbr)
