编写带有游标的存储过程,实现为职工长10%的工资。从最低工资开始长,最后工资总额限制在60万元以内。将涨过工资的职工id、name、涨后的工资,存入下面的临时表temp。

编写带有游标的存储过程,在数据库环境中通常用于处理一系列需要迭代操作的任务,这里是为了计算并更新职工的工资,同时符合条件地将结果存入临时表。以下是一个基于SQL Server的例子,假设我们有一个名为`Employees`的表,包含`EmployeeID`, `Name`, 和 `BasicSalary`字段:
```sql
CREATE PROCEDURE UpdateSalaryWithBonus
AS
BEGIN
DECLARE @CurrentSalary INT,
@MaxTotalSalary DECIMAL(10, 2) = 6000000.00, -- 60万元
@TempTable TABLE (EmployeeID INT, Name VARCHAR(50), NewSalary DECIMAL(10, 2))
DECLARE cursor CURSOR FOR
SELECT EmployeeID, BasicSalary
FROM Employees
ORDER BY BasicSalary ASC
OPEN cursor
FETCH NEXT FROM cursor INTO @CurrentSalary
WHILE @@FETCH_STATUS = 0
BEGIN
-- 计算10%的工资增长,并检查是否超出最大总额
SET @NewSalary = CASE WHEN @CurrentSalary * 1.1 <= @MaxTotalSalary THEN @CurrentSalary * 1.1 ELSE @MaxTotalSalary END
INSERT INTO @TempTable (EmployeeID, Name, NewSalary)
VALUES (@CurrentSalary, [Name], @NewSalary)
-- 更新当前工资,并继续下一位职工
UPDATE Employees
SET BasicSalary = @NewSalary
WHERE EmployeeID = @@FETCH_KEYVAL
FETCH NEXT FROM cursor INTO @CurrentSalary
END
CLOSE cursor
DEALLOCATE cursor
-- 最后,将涨后的工资信息插入到临时表中
INSERT INTO @TempTable (EmployeeID, Name, NewSalary)
SELECT EmployeeID, Name, BasicSalary FROM Employees
WHERE NOT EXISTS (SELECT * FROM @TempTable WHERE EmployeeID = Employees.EmployeeID)
-- 显示结果
SELECT * FROM @TempTable
END
```
