Sql server 删除记录的存储过程

我创建了3个用于插入、更新和删除记录的存储过程

虽然插入和更新记录存储过程工作正常，但我无法通过删除存储过程删除记录

该存储过程中的代码如下所示：

CREATE PROCEDURE usp_DeleteEmployeeRcord
    (@Name NVarchar(50),
     @FName Nvarchar(50),
     @Address NVarchar (50),
     @Email Nvarchar(50),
     @Mobile NVarchar(50),
     @Pincode NVarchar(50))
AS 
BEGIN
    DELETE [dbo].[EmployeeDetails]  
    WHERE Pincode = @Pincode
END

---

您必须使变量成为可选变量，但不在过程中传递：

使用此修改的：

CREATE PROCEDURE usp_DeleteEmployeeRcord
(
 @Name NVarchar(50)='',
 @FName Nvarchar(50)='', 
 @Address NVarchar (50)='', 
 @Email Nvarchar(50)='', 
 @Mobile NVarchar(50)='', 
 @Pincode NVArchar(50)
)

AS 
        BEGIN
            DELETE [dbo].[EmployeeDetails]  
            Where Pincode = @Pincode
        END

---

您在声明中忘记了FROM子句，它是

DELETE FROM dbo.EmployeeDetails WHERE ....

---

你在对账单中忘记了FROM子句，它是

DELETE FROM dbo.EmployeeDetails WHERE ....

---

因为您的

DELETE

语句不正确。正确的语法是

DELETE FROM <TableName> Where <Condition>

---

因为您的

DELETE

语句不正确。正确的语法是

DELETE FROM <TableName> Where <Condition>

删除记录的存储过程- 书籍详细信息示例如下：

    Create procedure[dbo].[DeleteBookDetails_SP] 
         @BookId Int
    As
    Begin   

         Delete from BookDetails Where BookId=@BookId

    End

---

这里“DeleteBookDetails\u SP”是存储过程名，“BookDetails”是表名，“BookId”是表中的列名。

删除记录的存储过程-

Use test
go

CREATE TABLE employee(  
id INTEGER NOT NULL PRIMARY KEY,  
first_name VARCHAR(10),  
last_name VARCHAR(10),  
salary DECIMAL(10,2),

)  


INSERT INTO employee VALUES (2, 'Monu', 'Rathor',4789,'Agra');  
GO  

INSERT INTO employee VALUES (4, 'Rahul' , 'Saxena', 5567,'London');  
GO  

INSERT INTO employee VALUES (5, 'prabhat', 'kumar', 4467,'Bombay'); 
go  

INSERT INTO employee VALUES (6, 'ramu', 'kksingh', 3456, 'jk');  
go  

select * from employee 


Create procedure MasterInsertUpdateDelete
(
@ID integer,  --//Mandatory parameters
@Firstname varchar(50)=Null,  --//optional parameters//--
@Lastname varchar(50)=Null,
@Salary Decimal(10, 2)=Null,

    begin
    delete from  employee where id=@ID

--For insert the records
exec MasterInsertUpdateDelete 7, 'Kallesh', 'Yadav', 30000, 'Bangalore', 'Insert'


--For update the records
exec MasterInsertUpdateDelete 4,'Sneha', 'Kumari', 23000, 'Mumbai', 'Update'

select *
from employee

--For delete the records
exec MasterInsertUpdateDelete  @ID = 2,  @Statementtype = 'Delete' -->We should specify the parameters name while deleting the specific records
