GetFieldSelections() returns a string with the current selections in a field.
If all but two, or all but one of the values are selected, the format 'NOT x,y' or 'NOT y' will be used respectively. If you select all values and the count of all values is greater than max_values, the text ALL will be returned.
Syntax:
GetFieldSelections ( field_name [, value_sep [, max_values [, state_name]]])
Return data type: string
Arguments:
| Arguments | Description |
|---|---|
| field_name | The field containing the range of data to be measured. |
| value_sep | The separator to be put between field values. The default is ', '. |
| max_values |
The maximum number of field values to be individually listed. When a larger number of values is selected, the format 'x of y values' will be used instead. The default is 6. |
| state_name |
The name of an alternate state that has been chosen for the specific visualization. If the state_name argument is used, only the selections associated with the specified state name are taken into account. For more information, see Using alternate states for comparative analysis. |
Examples and results:
The following example uses two fields loaded to different filter panes, one for First name name and one for Initials.
| Examples | Results |
|---|---|
|
Given that John is selected in First name. GetFieldSelections ([First name]) |
'John' |
|
Given that John and Peter are selected. GetFieldSelections ([First name]) |
'John,Peter' |
|
Given that John and Peter are selected. GetFieldSelections ([First name],'; ') |
'John; Peter' |
|
Given that John, Sue, Mark are selected in First name. GetFieldSelections ([First name],';',2) |
'NOT Jane;Peter', because the value 2 is stated as the value of the max_values argument. Otherwise, the result would have been John; Sue; Mark. |
