In database, you need to do Insert, Update and Delete. If we want to make a reliable and high performance system then these four operations must be implemented by stored procedures. Stored procedure also prevents Sql Injection attacks and reduce network traffic. For more about stored procedure refer the article Stored Procedure Plan Recompilation and Performance Tuning. This section of topics describes the techniques that LINQ to SQL provides for customizing insert, read, update, and delete operations in your application. The term Bulk Insert usually refers to the SQL Server specific ultra fast bcp based SqlBulkCopy implementation. It is built on top of IRowsetFastLoad. You perform Insert, Update, and Delete operations in LINQ to SQL by adding, changing, and removing objects in your object model. By default, LINQ to SQL translates. Insert Operation. We can insert records into the tables using stored procedure by passing data in input parameters.

Hi Vinz, mabuhay, and thank you for your blog It has been very helpful so far. Assuming that Im creating an insert form similar to the one at the top, but with.

Employee flag output,4,Deepak,1. Noida. print Successfully inserted. There is some error now see modified table. Select from Employee Retrieve Operation. We can retrieve data from one or more tablesviews with the help of join, using stored procedure. We can put multiple sql statements with in a single stored procedure. Below code is used to fetch data from a table Employee using stored procedure first we Insert data in the table. Insert into EmployeeEmp. ID,Name,Salary,Address Values1,Mohan,1. Delhi. Insert into EmployeeEmp. ID,Name,Salary,Address Values2,Asif,1. Delhi. Insert into EmployeeEmp. ID,Name,Salary,Address Values3,Bhuvnesh,1. Noida. Now we create a procedure to fetch data. CREATE PROCEDURE uspSelect. Employee. Select from Employee ORDER By Emp. ID Execute above created procedure to fetch data. Select. Employee Update Operation. We can update records of the tables using stored procedure by passing data in input parameters. Below code is used to update a table Employee using stored procedure CREATE PROCEDURE uspUpdate. Employee. flag bit output, return 0 for fail,1 for success. Address varchar1. BEGIN TRANSACTION. Update Employee set SalarySalary, AddressAddress. Where Emp. IDEmp. ID. IF TRANCOUNT 0. BEGIN commit TRANSACTION. IF TRANCOUNT 0. BEGIN rollback TRANSACTION. END Execute above created procedure to update table. Declare flag bit. EXEC uspUpdate. Employee flag output,1,2. Noida. if flag1 print Successfully updated. There is some error now see updated table. Select from Employee Delete Operation. We can delete records of the tables using stored procedure by passing data in input parameters. Below code is used to update a table Employee using stored procedure CREATE PROCEDURE uspDelete. Employee. flag bit output, return 0 for fail,1 for success. BEGIN TRANSACTION. Delete from Employee Where Emp. IDEmp. ID set flag1. IF TRANCOUNT 0. BEGIN commit TRANSACTION. IF TRANCOUNT 0. BEGIN rollback TRANSACTION. END Execute above created procedure to delete rows from table. Declare flag bit. EXEC uspDelete. Employee flag output, 4. Successfully deleted. There is some error now see modified table. Select from Employee Note. In stored procedure we use output parameter to return multiple values. Generally we use output parameter in stored procedure to get status of the operation as I used above flag output parameter to get operations status whether these are successfully executed or not. Summary. In this article I try to explain basic Insert, Retrieve, Update, Delete Operations using Stored Procedures. I hope after reading this article you will be know how to implement these operations using stored procedure. I would like to have feedback from my blog readers. Please post your feedback, question, or comments about this article. Simple Insert Update and Delete Triggers in SQL Server with example. In this article I will explain with simple examples, how to write Insert, Update and Delete Triggers in SQL Server. This tutorial is applicable for all versions of SQL Server i. Database. I have made use of the following table Customers with the schema as follows. I have already inserted few records in the table. Below is the Customer. Logs table which will be used to log the Trigger actions. Note You can download the database table SQL by clicking the download link below. Triggers. Triggers are database operations which are automatically performed when an action such as Insert, Update or Delete is performed on a Table or a View in database. Triggers are associated with the Table or View directly i. Triggers. Types of Triggers. There are two types of Triggers. After and Instead of Triggers. After Triggers. These triggers are executed after an action such as Insert, Update or Delete is performed. Instead of Triggers. These triggers are executed instead of any of the Insert, Update or Delete operations. For example, lets say you write an Instead of Trigger for Delete operation, then whenever a Delete is performed the Trigger will be executed first and if the Trigger deletes record then only the record will be deleted. Algorithmic Trading Software Open Source there. After Triggers. Now I will explain you with examples the After Triggers for Insert, Update and Delete operations. Insert Trigger. Below is an example of an After Insert Trigger. Whenever a row is inserted in the Customers Table, the following trigger will be executed. The newly inserted record is available in the INSERTED table. The following Trigger is fetching the Customer. Id of the inserted record and the fetched value is inserted in the Customer. Logs table. CREATETRIGGERdbo. CustomerINSERT       ONdbo. CustomersAFTERINSERTASBEGIN       SETNOCOUNTON       DECLARECustomer. Id. INT       SELECTCustomer. IdINSERTED. Customer. Id               FROMINSERTED       INSERTINTOCustomer. Logs       VALUESCustomer. Id,InsertedENDUpdate Trigger. Below is an example of an After Update Trigger. Whenever a row is updated in the Customers Table, the following trigger will be executed. The updated record is available in the INSERTED table. The following Trigger is fetching the Customer. Id of the updated record. In order to find which column is updated, you will need to use UPDATE function and pass the Column name of the Table to it. The UPDATE function will return TRUE for a Column if its value was updated else it will return false. Finally based on which column of the record has been updated a record containing the Customer. Id and the appropriate action is inserted in the Customer. Logs table. CREATETRIGGERdbo. CustomerUPDATE       ONdbo. CustomersAFTERUPDATEASBEGIN       SETNOCOUNTON       DECLARECustomer. Id.

Logs       VALUESCustomer. Id,ActionENDDelete Trigger. Below is an example of an After Delete Trigger. Whenever a row is delete in the Customers Table, the following trigger will be executed. The deleted record is available in the DELETED table. The following Trigger is fetching the Customer. Id of the deleted record and the fetched value is inserted in the Customer. Logs table. CREATETRIGGERdbo. CustomerDELETE       ONdbo. CustomersAFTERDELETEASBEGIN       SETNOCOUNTON       DECLARECustomer. Id. INT       SELECTCustomer. IdDELETED. Customer. Id               FROMDELETED       INSERTINTOCustomer. Logs       VALUESCustomer. Id,DeletedENDThe following screenshot displays the Log table after the above Triggers were executed. Instead Of Triggers. Below is an example of an Instead Of Delete Trigger. Whenever anyone tries to delete a row from the Customers table the following trigger is executed. Inside the Trigger, I have added a condition that if record has Customer. Id value 2 then such a record must not be deleted and an error must be raised. Also a record is inserted in the Customer. Logs table. If the Customer. Id value is not 2 then a delete query is executed which deletes the record permanently and a record is inserted in the Customer. Logs table. CREATETRIGGERdbo.
