This Flow Script tutorial explains how to use the Eval function with syntax and examples.


It is recommended to always use Eval for table operations in large datasets for better performance.

The Eval function in FlowScript is used to force the evaluation of a table expression. We recommend always using Eval() when dealing with large datasets. It is particularly useful when you need to pre-process or filter data in a table and plan to reuse this processed data later in your script. Eval essentially pre-calculates and stores the results of your table query, making your script more efficient by preventing the need to recompute the same data.


‌The syntax for the Eval function is:

Eval(table where x < 0)


table - the table on which the query is to be performed.


‌The Eval function returns a new table.
