What is the function of the "SUMMARIZE" command in SQLScript?

The "SUMMARIZE" command in SQLScript is specifically designed to aggregate data based on specified grouping criteria. This command allows you to combine rows from a dataset that share common values in specified columns, effectively generating a summary report. It facilitates operations such as calculating totals, averages, counts, or other aggregate functions for each group within the dataset.

When utilizing this command, you would generally specify the columns you want to group by, along with the aggregate functions that should be applied to the data in each group. For example, if you had a sales dataset and you wanted to find the total sales amount per region, you would use the "SUMMARIZE" command to achieve this aggregation efficiently.

The other choices correspond to different functionalities: creating new tables generally involves commands like "CREATE TABLE" rather than summarizing data; deleting records pertains to the "DELETE" statement; and filtering data is primarily done with the "WHERE" clause or through other filtering mechanisms rather than summarizing it. Therefore, the focus of the "SUMMARIZE" command on aggregation distinctly identifies it as the correct answer.
