開發工具與關鍵技術：sql資料庫、sql語句下面是基礎的sql語句，主要作用是在資料庫處理資料，後台**只是呼叫資料庫的sql語句，這樣會節省很多**。
1.查詢資料的sql語句：
if(@type=『chaxunshuju』)
begin
select
row_number () over(order by t_operators.operator_id) as number,
t_staff.staff_id,
t_operators.operator_id,
rtrim(t_staff.staff_name) as staff_name,
rtrim(t_operators.operator_accounts) as operator_accounts,
rtrim(t_operators.operator_password) as operator_password,
t_operators.effective,
rtrim(t_operators.note) as note
from t_staff inner join
t_operators on t_staff.staff_id = t_operators.staff_id
order by t_operators.operator_id desc
end2.新增資料的sql語句：
if(@type=『xinzengshuju』)
begin
if exists(select 0 from t_operators where operator_accounts=@operator_accounts)
begin
return
endelse
begin
insert into t_operators(staff_id, operator_accounts, operator_password, effective, note)
values (@staff_id, @operator_accounts, @operator_password, @effective, @note)
endend
3.修改資料的sql語句：
if(@type=『xiugaishuju』)
begin
update t_operators
set staff_id=@staff_id, operator_accounts=@operator_accounts,
operator_password=@operator_password, effective=@effective, note=@note
where operator_id=@operator_id
end4.刪除資料的sql語句
if(@type=『shanchushuju』)
begin
delete t_operators
where operator_id=@operator_id
end5.驗證重複資料的sql語句：
if(@type=『yanzhengchongfu』)
begin
if exists(select 0 from t_staff where staff_number=@staff_number or id_card=@id_card)
begin
return
endelse
begin
insert t_staff(as_employee_type_id, as_work_status_id, as_branch_id, staff_name,
staff_number, as_gender_id, age, id_card, birth, phone_number, address,
e_mail, entry_date, departure_date, operator_no, picture, note)
values (@as_employee_type_id, @as_work_status_id, @as_branch_id, @staff_name,
@staff_number, @as_gender_id, @age, @id_card, @birth, @phone_number,
@address, @e_mail, @entry_date, @departure_date, @operator_no, @picture, @note)
endend
