Building a Comment Hierarchy: Stored Procedures in SQL Server

Create a Comment Hierarchy in SQL Server with These Stored Procedures

Introduction

In this article, we'll dive into the creation of stored procedures for managing a Hierarchy Comment Section in a SQL Server database. If you haven't set up the database yet, refer to my previous article on Comment Hierarchy Comments Section Database in SQL Server. Now, let's explore the stored procedures that will enhance the functionality of our comment system.

StoredProcedure : spCheckUserCredentials

Our first stored procedure, named spCheckUserCredentials, is designed to check whether a given username already exists in the UserTable. This helps in validating user credentials before proceeding with any comment-related actions.

CREATE PROCEDURE spCheckUserCredentials(
@Username varchar(25))
As
 Begin
  Select * from UserTable where Username=@Username
 End

StoredProcedure : spCommentInsert

The spCommentInsert stored procedure is crucial for inserting new parent comments into the database table. It takes the username, comment message, and automatically captures the comment date.

CREATE PROCEDURE spCommentInsert(
@Username varchar(25),
@CommentMessage varchar(300))
As
 Begin
  Insert into ParentCommentTable(Username, CommentMessage, CommentDate)
         values(@Username, @CommentMessage, GETDATE())
 End

StoredProcedure : spCommentUpdate

The spCommentUpdate stored procedure allows users to update their existing comments. By providing the comment ID, username, and the new comment message, users can modify their contributions.

CREATE PROCEDURE spCommentUpdate(
@CommentID int,
@Username varchar(25),
@CommentMessage varchar(300))
As
 Begin
  Update ParentCommentTable set CommentMessage=@CommentMessage 
                            where CommentID=@CommentID and Username=@Username
 End

StoredProcedure : spCommentReplyInsert

For handling comment replies, we introduce the spCommentReplyInsert stored procedure. It enables users to insert replies to existing parent comments, linking them through the ParentCommentID.

CREATE PROCEDURE spCommentReplyInsert(
@Username varchar(25),
@CommentMessage varchar(300),
@ParentCommentID int)
As
 Begin
  Insert into ChildCommentTable(Username, CommentMessage, CommentDate, ParentCommentID)
         values(@Username,@CommentMessage, GETDATE(),@ParentCommentID)
 End

StoredProcedure : spGetParentComment

The spGetParentComment stored procedure retrieves all comments stored in the ParentCommentTable, facilitating the display of the entire comment thread.

CREATE PROCEDURE spGetParentComment
As
 Begin
  Select * from ParentCommentTable
 End

StoredProcedure : spGetParentCommentByUsername

To retrieve comments by a specific user, we use the spGetParentCommentByUsername stored procedure, allowing us to filter comments based on the provided username.

CREATE PROCEDURE spGetParentCommentUsername(
@Username varchar(25))
As
 Begin
  Select * from ParentCommentTable where Username=@Username
 End

StoredProcedure : spGetChildCommentByParentCommentID

Lastly, the spGetChildCommentByParentCommentID stored procedure is employed to fetch all child comments associated with a particular parent comment ID.

CREATE PROCEDURE spGetParentCommentByParentCommentID(
@ParentCommentID int)
As
 Begin
  Select * from ChildCommentTable where ParentCommentID=@ParentCommentID
 End

Conclusion

With these stored procedures, you have a robust foundation for managing a Hierarchy Comment Section in your SQL Server database. Whether it's checking user credentials, inserting comments, updating existing ones, or handling replies, these stored procedures provide the necessary functionality for a dynamic and interactive comment system. Feel free to integrate and customize these procedures into your ASP.NET application for a seamless user experience.
