Which variable is used in the Generic SQL detector to indicate the Start date/time of the query?

The variable used in the Generic SQL detector to indicate the Start date/time of the query is commonly recognized as @StartDatetime. This variable serves to define the beginning point in time from which the query will pull historical data, facilitating the analysis of data trends and changes over a specified period.

Having a clear starting date/time is crucial in any data querying situation, as it ensures that users can accurately retrieve the information intended for analysis, avoiding any data sets that do not meet the relevant temporal criteria.

In contrast, other variables might not be recognized in the same context or may serve different functions within the framework of the AVEVA Historian's SQL detection mechanism. Understanding the specific nomenclature used in the system is key for anyone looking to effectively utilize these tools for data monitoring and evaluation.
