Count

Count(Number a[ ])

This function computes the number of the values in an array.

Parameter

a - A Double array.

Return value

The return value is an Integer.

Examples

The return value of the following statement is 7.
Count([11.2, 15.4, 13.7, 16.9, 15.2, 14.8, 10.6])
The return value of the following statement is 4.
Count([-20.4, -26.4, -68.7, -84.1])

Count(DBField a)

The function is used to count the number of values referred to by the argument.

Parameter

a - Values of DBField or formula field.

Return value

Returns a Number type value.

Examples

Number x = Count(@dbfield)
Number x = Count(@formula)

Count(DBField a, String groupby)

The function is used to count the number of values referred to by the first argument.

Parameters

a - Values of DBField or formula field.
groupby - A constant string to indicate the groupby DBField name, formula name grouped by or a parameter name grouped by.

Return value

Returns a Number type value.

Examples

Number y = Count(@"Customer Name", @Customers_Region)
Number x = Count(@formula, @formula_groupby)
Number x = Count(@dbfield, @parametger_groupby)

Note: If a field is assigned to a variable, for example x, the variable x will lose the characteristic of representing a group of values. The following formula will then be treated as incorrect.

Number x = @dbfield; Number y = Count(x); // system will prompt you that there is no such kind of function.
