Unable to delete all the rows in the table

Hi all

According to the time range I'm removing the equipment data and travel work shifts then insert new data of mth_site_shift_definitions in the work day moves and equipment move the table. If mth_Site_shift_definitions table has three rows for a given plant and I delete the two lines in a time then I am able to delete data for movement of equipment and work sihfts table, and then click Insert data in a single row in these two tables, but when I try to remove the last line I get an SQL exception. Can someone tell me the reason for this exception. In fact, I want that if we delete the last row also mth_Site_shift_definitions then the corresponding data should also get demolished transfers of equipment and work instead of give to the exception. I have this code:
