SearchGuard

In a professional situation, an incorrectly selected record can result in a mortifying loss of data. Therefore, it behooves one to select the proper row carefully in one's stored procedure. That's why Charles's development team uses SearchGuard, the premier design pattern for selecting just the right row:


DELETE FROM [dbo].[tbl_employee] WHERE ((
	[employee_id] = @Original_employee_id) 
	AND ([salesperson_flag] = @Original_salesperson_flag) 
	AND ([first_name] = @Original_first_name) 
	AND ([last_name] = @Original_last_name) 
	AND ((@IsNull_job_title_type_id = 1 
	AND [job_title_type_id] IS NULL) OR ([job_title_type_id] = @Original_job_title_type_id)) 
	AND ((@IsNull_address_id = 1 AND [address_id] IS NULL) OR ([address_id] = @Original_address_id)) 
	AND ((@IsNull_work_extension = 1 AND [work_extension] IS NULL) OR ([work_extension] = @Original_work_extension)) 
	AND ((@IsNull_home_phone_number = 1 AND [home_phone_number] IS NULL) OR ([home_phone_number] = @Original_home_phone_number)) 
	AND ((@IsNull_alternate_phone_number = 1 AND [alternate_phone_number] IS NULL) OR ([alternate_phone_number] = @Original_alternate_phone_number)) 
	AND ((@IsNull_relative_name = 1 AND [relative_name] IS NULL) OR ([relative_name] = @Original_relative_name)) 
	AND ((@IsNull_relative_phone_number = 1 AND [relative_phone_number] IS NULL) OR ([relative_phone_number] = @Original_relative_phone_number)) 
	AND ((@IsNull_hire_date = 1 AND [hire_date] IS NULL) OR ([hire_date] = @Original_hire_date)) 
	AND ((@IsNull_termination_date = 1 AND [termination_date] IS NULL) OR ([termination_date] = @Original_termination_date)) 
	AND ((@IsNull_team_type_id = 1 AND [team_type_id] IS NULL) OR ([team_type_id] = @Original_team_type_id)) 
	AND ((@IsNull_comment = 1 AND [comment] IS NULL) OR ([comment] = @Original_comment)) 
	AND ((@IsNull_social_security_number = 1 AND [social_security_number] IS NULL) OR ([social_security_number] = @Original_social_security_number)) 
	AND ((@IsNull_drivers_license_number = 1 AND [drivers_license_number] IS NULL) OR ([drivers_license_number] = @Original_drivers_license_number)) 
	AND ((@IsNull_badge_number = 1 AND [badge_number] IS NULL) OR ([badge_number] = @Original_badge_number)) 
	AND ((@IsNull_hourly_wages = 1 AND [hourly_wages] IS NULL) OR ([hourly_wages] = @Original_hourly_wages)) 
	AND ((@IsNull_w2_claim = 1 AND [w2_claim] IS NULL) OR ([w2_claim] = @Original_w2_claim)) 
	AND ((@IsNull_insurance_start_date = 1 AND [insurance_start_date] IS NULL) OR ([insurance_start_date] = @Original_insurance_start_date)) 
	AND ((@IsNull_date_of_birth = 1 AND [date_of_birth] IS NULL) OR ([date_of_birth] = @Original_date_of_birth)) 
	AND ((@IsNull_shirt_size_type_id = 1 AND [shirt_size_type_id] IS NULL) OR ([shirt_size_type_id] = @Original_shirt_size_type_id)) 
	AND ([active_flag] = @Original_active_flag) AND ([network_userid] = @Original_network_userid) 
	AND ((@IsNull_vacation_days = 1 AND [vacation_days] IS NULL) OR ([vacation_days] = @Original_vacation_days)) 
	AND ((@IsNull_sick_days = 1 AND [sick_days] IS NULL) OR ([sick_days] = @Original_sick_days)) 
	AND ((@IsNull_last_vacation_update = 1 AND [last_vacation_update] IS NULL) OR ([last_vacation_update] = @Original_last_vacation_update)) 
	AND ([part_time_flag] = @Original_part_time_flag) 
	AND ((@IsNull_part_time_hours = 1 AND [part_time_hours] IS NULL) OR ([part_time_hours] = @Original_part_time_hours)) 
	AND ([first_eligible_bonus_received] = @Original_first_eligible_bonus_received) AND ((@IsNull_first_eligible_bonus_received_date = 1 AND [first_eligible_bonus_received_date] IS NULL) OR ([first_eligible_bonus_received_date] = @Original_first_eligible_bonus_received_date)) 
	AND ([awa_location_id] = @Original_awa_location_id) 
	AND ([rowguid] = @Original_rowguid) 
	AND ((@IsNull_bonus_view_date = 1 AND [bonus_view_date] IS NULL) OR ([bonus_view_date] = @Original_bonus_view_date)) 
	AND ((@IsNull_ceiva_flag = 1 AND [ceiva_flag] IS NULL) OR ([ceiva_flag] = @Original_ceiva_flag)) 
	AND ([ethnicity_id] = @Original_ethnicity_id) 
	AND ((@IsNull_sex = 1 AND [sex] IS NULL) OR ([sex] = @Original_sex)))

Its powerful protection reduces the risk of false positives to practically zero, and with a plethora of fields to match on, it's virtually impossible to delete the wrong row.

SearchGuard: Anything less would be uncivilized.
