Depending on the data type, you can compare values in separate columns or single columns against fixed values.
You can use basic comparison operators to perform comparisons on your data. In this example, the compareCol column is generated as the evaluation of 3 < 6
, which is true
:
Transformation Name | |
---|---|
Parameter: Formula type | Single row formula |
Parameter: Formula | (3 < 6) |
Parameter: New column name | 'compareCol' |
For more information, see Comparison Operators.
Boolean values can be true
or false
, so comparisons like the following can be applied to a Boolean set of values:
Transformation Name | |
---|---|
Parameter: Columns | Attendance |
Parameter: Formula | IF(isSeated == true,true,Attendance) |
In the above case, the value in Attendance
is set to true
if the value in the isSeated
column is true
. Otherwise, the current value in Attendance
is used.
You can use the DATEDIF
function to compare two date values, as in the following, which compares the number of days between startCol
and endCol
values:
Nota
Both parameters of the DATEDIF
function must be column references containing valid date values.
Transformation Name | |
---|---|
Parameter: Formula type | Single row formula |
Parameter: Formula | DATEDIF(startCol, endCol, 'day') |
Parameter: New column name | 'DurationInDays' |
