RangeCount() returns the number of values, both text and numeric, in the expression or field.
Syntax:
RangeCount(first_expr[, Expression])
Return data type: integer
Arguments:
The argument of this function may contain inter-record functions which in themselves return a list of values.
- first_expr: The expression or field containing the data to be counted.
- Expression: Optional expressions or fields containing additional data to be counted.
Limitations:
NULL values are not counted.
Examples:
| Example | Result |
|---|---|
| RangeCount (1,2,4) |
Returns 3 |
|
RangeCount (2,'xyz') |
Returns 2 |
| RangeCount (null( )) | Returns 0 |
| RangeCount (2,'xyz', null()) | Returns 2 |
Example: (using expression)
RangeCount (Above(MyField,1,3))
Returns the number of values contained in the three results of MyField. By specifying the second and third arguments of the Above() function as 3, it returns the values from the three fields above the current row, where there are sufficient rows, which are taken as input to the RangeSum() function.
| MyField | RangeCount(Above(MyField,1,3)) |
|---|---|
|
10 |
0 |
| 2 | 1 |
| 8 | 2 |
| 18 | 3 |
| 5 | 3 |
| 9 | 3 |
Data used in examples:
RangeTab:
LOAD * INLINE [
MyField
10

9
] ;
Example: (in table form)
Add the example script to your document and run it. Then add, at least, the fields listed in the results column to a sheet in your document to see the result.
RangeTab3:
LOAD recno() as RangeID, RangeCount(Field1,Field2,Field3) as MyRangeCount INLINE [
Field1, Field2, Field3
10,5,6
2,3,7
8,2,8
18,11,9
5,5,9
9,4,2
];
The resulting table shows the returned values of MyRangeCount for each of the records in the table.
| RangeID | MyRangeCount |
|---|---|
| 1 | 3 |
| 2 | 3 |
| 3 | 3 |
| 4 | 3 |
| 5 | 3 |
| 6 | 3 |
