Filter by Expression

This transformation calculates an expression for every row (without adding a new column) and leaves only rows where this expression is true. Other rows are removed.

The expression should be logical and return a boolean value (i.e. either true or false).

Examples of conditions

[Amount]=0

[Length] * [Width] * [Height] <= 1000

contains([City], 'York')

not isempty([Email])

If no rows satisfy the condition then all rows get removed.
