Principes fondamentaux d'Alteryx

An AND statement means that BOTH criteria are met.

Custom expressions for the same field must have the field name stated before each criteria, such as [Date] > 2010 AND [Date] < 2024.

Data types do not matter in writing expressions.

When writing expressions for string values, no quotes are needed.

An OR statement means that BOTH criteria are met.

When writing expressions for string fields, if the criteria appears to be a number, do not use quotes.
