MyDriveWorks - Tech Tips
There are many different Table Functions inside DriveWorks, this Project demonstrates some of these Functions.
Lists all the values, pipe-bar separated, in the specified column of the specified table (the values in the first row are treated as header values and are excluded)
ListAll([Table], [Column], [Sort Ascending] )
Where:
Table is the table from which to retrieve the data.
Column is the number of the column within the table to retrieve the data from.
Sort Ascending (Optional) is TRUE to sort the results in ascending order, FALSE to sort descending.
Rule | Meaning |
|---|---|
| ListAll(DWLookupVehicles, 1) | The function looks in the Vehicles table, and retrieves all the data in the first column in the original order.
In this case, that first column contains car makes, so the list; "Volkswagen|Ford|Renault|Ford|Mazda|Volkswagen|Volkswagen|Ford|Renault" is returned. |
| ListAll(DWLookupVehicles, 1, TRUE) | The function looks in the Vehicles table, and retrieves all the data in the first column in ascending order.
In this case, that first column contains car makes, so the list; "Ford|Ford|Ford|Mazda|Renault|Renault|Volkswagen|Volkswagen|Volkswagen" is returned. |
| ListAll(DWLookupVehicles, 1, FALSE) | The function looks in the Vehicles table, and retrieves all the data in the first column in descending order.
In this case, that first column contains car makes, so the list; "Volkswagen|Volkswagen|Volkswagen|Renault|Renault|Mazda|Ford|Ford|Ford" is returned. |
| ListAll(DWLookupPeople, 3) | The function looks in the People table, and retrieves all the data in the third column in the original order.
In this case, that third column contains ages, so the list; "25|37|42|21|56" is returned. |
| ListAll(DWLookupPeople, 3, TRUE) | The function looks in the People table, and retrieves all the data in the third column in ascending order.
In this case, that third column contains ages, so the list; "21|25|37|42|56" is returned. |
| ListAll(DWLookupPeople, 3, FALSE) | The function looks in the People table, and retrieves all the data in the third column in descending order.
In this case, that third column contains ages, so the list; "56|42|37|25|21" is returned. |
