The records in Microsoft SQL Server database can be placed and located in the form of a B-tree. These records are divided into various pages (child pages), each having a unique index page, which is one level up in hierarchy from the child page. Corruption in the hierarchical tree structure (metadata structure corruption) primarily results in loosing the reference of the child page from the Index page. In such situations, the data stored in the database becomes inaccessible. For accessing the data stored in the database, an ideal way is to restore it from an updated database backup. But if in case of absence of an valid database backup, you will need to use advanced MS SQL Database Recovery application to repair your database.

Consider a practical scenario, where you receive the below error message when you attempt to access the records stored in table:

“Table error: Object ID O_ID, index ID I_ID. Parent node for page P_ID was not encountered.”

The above error message makes the data stored in table inaccessible. Moreover, the error message repeatedly repeats every time you attempt to access the records stored in the table.

Cause:

The root cause for the occurrence of the above error message is SQL database corruption due to metadata structure damage.

Note: SQL database can be corrupted either due to logical or physical factors.

Resolution:

To resolve the above error message and to access the table records, you will need to follow the below measures:

• To solve all the corruption issues caused due to physical damage, swap the corrupt system component with a new component.
• To solve  all the corruption issues caused due to logical damage, run DBCC CHECKDB command with correct repair clause.
  

The first measure is competent enough to resolve all the physical damage issues. The second measure, however, fails to resolve all logical corruption problems. For such situations, the database table can be repaired by using advanced MS SQL Database Repair software. These SQL server Recovery utilities employ effective scanning methods to completely repair the corrupt table after all logical database corruption scenarios.

The background process of “Ghost Cleanup” in MS SQL database is primarily used to improve the performance of Delete command. This record count of total number of the ghosted records is stored in the header. However, if the record count in the header does not match with the exact number of ghosted records, then you receive an error message. The cause for the error message is corruption of your SQL database records. In such situations, it is always advisable to restore the data from an updated database backup. But if in case, you have not maintained any backup, or the database backup is corrupt, then you will need to repair the database by using advanced SQL Database Repair application.

Consider a practical scenario, where you encounter the below error message while attempting to access your database table:

“Object ID O_ID, index ID I_ID: The ghosted record count (HG_COUNT) in the header does not match the number of ghosted records (G_COUNT) found on page P_ID.”

The same error message appears every time you attempt to access the table records.

Cause:

The root cause for the above error message, as stated in the message, is that the number of ghosted records found on a particular page P_ID is not matching ghosted record count in the header. This mismatch primarily occurs due to SQL database corruption due to logical or physical reasons.

Resolution:

The resolution for the above error message is categorized in two steps:

    * In case the SQL database corruption has occurred due to any physical damage of a component, then you will need to replace the component with a new one.
    * In case of logical corruption of SQL database, you will need to repair the database using ‘DBCC CHECKDB’ command, with an appropriate repair clause.

The repair command ensures repair of corrupt database in almost every situation. However, if the command is unable to repair the database, then you will need to use powerful third-party SQL Database Repair application. Such MS SQL Repair tools repair the corrupt database by using effective repairing procedures. These tools are downloadable from the Internet.

SQL Server database corruption can occur due to SQL Server malfunctioning, improper system shutdown, virus infection, hardware failure and many more. Once SQL database gets corrupted, SQL server database become inaccessible. In such situations, use your backup, if there is no backup, the user needs to repair mdf file. Consider a practical scenario, where a user is working on SQL Server 2005 and creating a report. While doing so, the Windows restarts due to power failure. When users restart the system, the SQL database becomes inaccessible. When the user tries to attach the MDF manually, he encounters the below error message:

“An exception occurred while executing a Transact-SQL statement or batch. _db.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171).” Or

“C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\MYDATABASE.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171)” In such circumstances, the database administrators recommend to attach a single file. However, when the user uses sp_attach_single_db Stored Procedures, the user encounters the following error message:

“Server: Msg 5172, Level 16, State 15, Line 1 The header for file path……\.mdf is not a valid database file header. The PageAudit property is incorrect.”

The above issue occurs when the MDF file header gets corrupted or some invalid information is inserted in the header file. All these situations result, inaccessibility of the SQL database. To ensure accessibility of the SQL database, the user needs to recover it by using the latest backup. But sometime user has not created any backup of its database or mdf file, then he needs to perform MDF repair. To do so, user needs to use efficient and effective SQL MDF repair application.

A database is an integrated collection of the data and records in structured way. The data in a database is organized according to a database model. The most commonly database model is relational model.

There are two types of database systems: relational and flat-file. In flat file database the user specifies the data attributes for one table at a time, storing data independently from application. While relational database, along with the flat file approach, allows the user to specify the information about multiple tables and the relationships among the tables, and often declarative controls over, which bind the table to obey them, particularly called constraints.

The DBMS implementing the relational database approach is called Relational Database Management System (RDBMS). Now at the marketplace there is a range of relational database management systems available such as MS Access, MS SQL Server and MySQL.

MS Access is a RDBMS which uses the relational MS Jet Database Engine. This Microsoft product is used within departments of large and small corporations. MS SQL is also a Microsoft product which implements the query language SQL (Structured Query Language). MySQL has been developed by MySQL AB and offers all the advanced features of a relational database management system.

The advantages like application-data independence, enhanced data integrity, improved security, reduced data redundancy and inconsistency etc. have lead the users to store more and more data on these databases. But side by side the complications to these databases are also growing with the fast pace which are resulting into the database corruption. This is increasing the need of database repair. Some of the common database corruption reasons include:

·     Interruptions or crashes during the writing of data.
·     Virus hit
·     Application malfunction
·     Unreliable network connections and hardware
·     Hard disk error
·     Too many users attempting for editing the database at the same time
·     Poor structuring of the software that interfaces with the database

 All these reasons have a common impact viz. database corruption and the data loss. The database repair is demanded at the peak level of importance in this case.  For mostly all the organizations, they must keep track of the information including their employees, dealers, shareholders, creditors, debtors etc. and the database allows you to mange and use an incredible variety of information easily.

The database allows you to maintain order in what could be a very chaotic environment and possess most of the relevant information of the organization. So corruption of any of the database may result into big loss for the organization and hence an immediate database repair is required in either of the database corruption scenario.

Fortunately, technology has availed us the remedy to this database corruption in the name of database repair software. These software are designed so as to scan the corrupted database and retrieve the data intact. As relationships play the most important role in the relational model, therefore while choosing the database repair software, one should be sure that the software is not going to perform any write operation. Based on the RDBMS you are using, go for the relevant database repair software.

Exporting MS Access database components in MS Word Merge format or MS Excel format is the common practice followed by database users. While exporting the database objects provides various benefits, it can also become a cause of Access database corruption. In many cases, the Access database becomes inaccessible and demountable. To regain the affected database data, you should restore the Access database from an updated backup. However, if you have not created any such backup or the backup fails to restore data, then you need to use advanced access database repair tools.

Consider a practical example, where you receive the below error message when you export a table (Employee) from a Microsoft Access database (in .mdb format) to the Microsoft Word Merge format:

“The data being exported does not match the format described in the Schema.ini file.”

Furthermore, you receive another error message if you use VBA (Visual Basic for Application) code:

Run-time error ‘3438’

Cause:

The main cause behind the above error message is that when you export the Employee table for the first time, the field names of the table for the Microsoft Word Merge format get saved in the Schema.ini file. A schema.ini (schema information) file provides information about the general format of the file, column name and data types. So, if you again export the employee table, it does not match with previously exported fields. Another major reason behind mismatching fields can be Access database corruption. In both the cases, if you try to import the Employee table, you will receive the above error messages.

Resolution:

To resolve the errors, Microsoft suggests opening the schema.ini file by using Notepad and then modifying all the field names that are causing the problem. However, in case of database corruption, you need to repair the MS Access database and then apply the above resolution. To completely repair the MS Access database, you should use advanced Access Database Repair utilities. Such Access Repair tools incorporate effective scanning algorithms to perform thorough repair and restoration of all affected Access database components. These applications can be easily understood without prior technical knowledge as they come with largely graphical interface and user-friendly documentation.

RAID servers are considered as the most trusted and reliable storage medium. But sometimes, they may also lose all the hard drives, which contains your important data, backups and other files.

Most of the organizations use RAID for storing their important SQL Server databases. When they fail, normally you may lose all of your data.

In such situations, you can save your data by restoring the database from your backup. But sometime, when you try to restore backups, you may receive the following error message:

“Msg 3270, Level 0, Sev 16.

An internal consistency error occurred. Contact Technical Support for assistance.”

In this case, when you attempt to detach the database using sp_detach_db stored procedure and then attempt to attach the database again with the help of sp_attach_db stored procedure, you may get the flowing error message:

“Server: Msg 5172, Level 16, State 15, Line 1.

The header for file ‘d:\pubs.mdf' is not a valid database file header. The PageAudit property is incorrect.”

After this error message, the restoration process gets halted and you can not access anything from your SQL Server database.

As stated in the above error messages, this problem is either due to inconsistent state of the database or due to invalid header entry for the database. In both of these cases, the database may get corrupted and then you are not able to access even a single data from it.

In such situations, you need to perform SQL recovery to repair the damaged database and retrieve all of your data from it. SQL recovery can be carried out using the SQL Database repair software.

SQL Database repair software are easy to use, which allow you to have quick and trouble-free MDF repair in each and every case of MDF corruption. To ensure complete and successful SQL repair, always use effective SQL database recovery software.

You may receive the following error messages in SQL Server:

Server: Msg 3624, Level 20, State 1, Line 1
Location: recbase.cpp:1378
Expression: m_offBeginVar < m_SizeRec
SPID: 51
Process ID: 948
Connection Broken

Or

[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionCheckForData (CheckforData()).
Server: Msg 11, Level 16, State 1, Line 0
General network error. Check your network documentation.
Connection Broken

These error messages mostly receive when the user attempts to insert a column to the existing table through INSERT command. If the applied transaction also retains the foreign key reference to the column, which has been affirmed as the exclusive clustered or non-clustered index key on the table, then this could be the reason of this problem. In this situation, the clustered index gets corrupted or damaged. When the added column attempt gets failed, the clustered index can get damaged and all of the data may become inaccessible.

If the clustered index got corrupt, then, no report will be generated by running the DBCC CHECKDB, but the access performance of the database gets degraded and hence you need an instant SQL recovery through the trustworthy tool and choose the best sql database repair software for better results.

The best way out to SQL repair totally, is to make use of the third party applications which are well suited for this situation. In fact, they avail a secure MDF recovery and so are recommended for the best part. With the intuitive user interface, this MDF repair utility helps you to work with its easy process.

The records saved in the MS Access database form core component of Access database files (.mdb and .accdb). You can save your records in various MS Access database components like tables, forms, views, reports etc. Various factors responsible for the damage of records can be concurrent modification by two or more users on the same record, software bugs, network hardware failure and more. In such situations, you need to recover the damaged records by using latest data backup. However, if you have not maintained any backup, you need to recover and restore the lost data by using Access Recovery tools.

Consider a scenario when you attempt to access the records saved in the “Marketing” table, you find that some of the records have been marked as “#Deleted.” This indicates that the Access database has been corrupted. Few main reasons for the Access database corruption are discussed as follows:

• Two users in multi-user environment were attempting to modify the records of the same table.

• Improper shutdown of the Microsoft Jet connection due to power outage.

• ActiveX Data Objects (ADO) and Data Access Objects (DAO)

• Faulty Network Hardware

• Malicious software like virus

• Large number of open and close operations in a sequence.

Resolution:

To resolve the above issue and access the database records in “Marketing” table, you need to use an inbuilt repair utility known as Compact and Repair. To use the utility, you need to follow these steps:

1. Go to the Tools menu, select Database Utilities and then click Compact and Repair Database.

2. Locate and then click the database in the ‘Database to Compact From’ dialog box, and then click Compact.

3. Select an appropriate folder location for the new file in the ‘Compact Database Into’ dialog box, type a unique name for the file and then click on Save.

However, the above inbuilt utility can not be used to repair the database greater than

2 GB in size. In such circumstances, you need to repair and restore the Access database components by using advanced and effective Access Repair tool. Such Access Database Repair utilities employ influential scanning methods to provide absolute and systematic database repair of all Access database components. With interactive and user-friendly interface, these utilities can be easily used to repair and restore corrupted Access databases without prior technical knowledge.

Sometimes when you try to open a table, query, form, report or a data access page you may find the following error message:

“Record is deleted.”

Now, in the case of a table or a query the error message displayed may be in the form:

“Msaccess can't open the table in datasheet view.”

While if you are deal with a report the error message may take the following form:

“Unable to carry out the command.
There was an error executing the command.”

This behavior publicized by the MS Access in the multi user environment while the database is stored on the network. When the LAN is spread in a building or a more wide area, then it is a universal practice take up by the users to save an Access database on the network so that it can make them easy to keep an eye that the work is going in the right direction or not.. These databases generally hold some important company or organization related information which can not be lost at any cost. So it is required that no data loss may take place and the data will remain safe.

The above mention error messages arise if either the object or the whole of the database is corrupted or damaged. The problem occur when the similar record in the database is being modified by two or more users all together and in the mean time if any of the user forces the Access to close by shutting down his/her computer.

To resolve this problem Microsoft has recommended repairing the database using Compact and Repair utility tool. But there is a downslide to it, this tool didn’t work so, at last database remains damaged or corrupted. In this case the only option left to repair the database is to imply good access database repair software. This software is read only software and repairs your database without changing the original content of the database.
