Dewarticles: SQL Database Stores the data in the form of pages. These logical pages are assigned to save the databases. Each page is further divided into 8 KB of pages where the data is stored. All the pages have proper indexes through which data is retrieved by SQL query. Every page consists of a page header that comprises entire page index information.
So, whenever a user runs a query to display the data, the header information checks with the page information, if it doesn’t match then one can face the database error 8946. Like this error, we may face several Fatal errors while dealing with SQL Server. So, many times these errors can be resolved using DBCC Check Commands but it is not always suitable to Fix the SQL Error 8946. So, in this blog, we are going to discuss the proper solution to fix this error.
Before we get to know the solution to this error, let’s first discuss what is sql server and general reasons due to which the server generates error 8946.
What is SQL Server?
Similar to other RDBMS software, SQL Server is also used widely by many Organizations. It is developed and marketed by Microsoft. It is one of the standard programming language for interacting with relational databases. User can fetch any data records using the SQL queries.
Microsoft SQL Server has various versions such as SQL Server 2022, 2019, 2017, 2016, 2014, 2012, 2008 R2, 2008, 2005, 2000, 7.0, 6.5 and 6.0 that have been released.
Nowadays there are various SQL versions available in the market. It works exclusively on Windows environment and now also available on Linux.
It basically creates three file formats
- MDF
- NDF
- LDF
MDF: MDF is a master database file. It stores the users data in the form of rows, columns, fields, indexes, views and tables. MDF file can be loaded to database using Microsoft SQL Server.
NDF: A file with .ndf extension is a secondary database file used by SQL Server. It is s secondary storage file because SQL Server stores user specified data in primary storage file known as MDF.NDF file is optional and is user defined to manage data storage.
LDF:LDF is log file which stores all the transactions maintained by SQL Server. It can help you fetch any time log activity performed by users.
Reasons Responsible for Server Error 8946 in SQL
There are various factors responsible for SQL Server error code 8946. This error is a page-level corruption that makes the files inaccessible. Once the page header gets damaged or corrupted, it might result in data loss. Some of the general reasons are given below for server error 8946:
Due to corruption in the header page
- Abruptly shutdown of the system during any SQL Transaction
- Any Malware or bug occurs in SQL Server
- Improper functioning of Hardware.
- Any upgrade in the SQL Server version, there may be compatibility issues might occur.
Any above reasons may corrupt the database file and becomes inaccessible to the user. The real problem arises when the header file lost doesn’t match with the page information then there might be a chance of data loss and it can’t be rollback manually.
