Based on the provided information, it appears that you want to delete duplicate rows from a table named hourly_report_table. To do this, you can use the following SQL query: DELETE FROM hourly_report_table WHERE rowid NOT IN ( SELECT MAX(rowid) FROM hourly_report_table GROUP BY column1, column2, column3, column4 ); Replace column1, column2, column3, and column4 with the actual column names of your table. This query deletes all rows from the table that do not have the maximum rowid for each group of values in the specified columns.
