How to fix error message 7105 in SQL Server?

Microsoft SQL stores large amounts of data and supports large objects(LOB) datatypes to store multimedia files like images. But sometimes,  these datatypes become harmful for the SQL database and generates an error message 7105. This guide explains all the measures to fix this error.

Why Error 7105 occurs in Microsoft SQL Database?

Large Objects within the SQL file consist of  BLOB (binary large data types of objects), CLOB (character large data types of objects) and DBCLOB. These objects have their own storage system but there are many situations when SQL server page row becomes unavailable. Whenever a user executes a query on the server and unable to access LOB datafiles then Msg 7105 occurs. This error looks like completely as follows:

“Msg 7105, Level 22, State 6, Line 1

Database ID 11, Page (255:177), slot 1 for LOB data type node doesn’t exist. This usually is caused by transactions that can read uncommitted data on a data page. Run DBCC CHECKTABLE.”

The severity level here is 22 which is very high and thus connection terminated by the server. 

Reasons behind for occurrence of “Error 7105 in SQL”-

There are many reasons as given below:

• This error occurs due to database corruption lies in LOB structure.
• A query failure occurs with the use of READ UNCOMMITTED ISOLATION or the NOLOCK query suggestion.
• With this error, the SQL server engine causes the query to fail.

Quick Steps to fix Error message 7105

The main reason for error 7105 in SQL is the database corruption in the database page. So, here some steps are given to fix it as follows:

1. Initially, run the DBCC CHECKDB command on the server or you can run the DBCC CHECKTABLE  command on the basis of a table that is stated in the error message.
2. If the error generates because of the server engine then updating the latest service pack of SQL Server will help in fixing the error.
3. The error is generated due to a written query then again rewrite the query and run the same.
4. From the last backup, restore the .mdf file.
