It is recommended to always use Eval for table operations in large datasets for better performance.
The Eval function in is used to force the evaluation of a 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.
