Compare Values
Depending on the data type, you can compare values in separate columns or single columns against fixed values.
Compare Numeric 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.
Compare Boolean Values
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.
Compare Date Values
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:
注記
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' |
