SQL Database repair & recovery

You can use the stored procedure to run a sequence of the SQL statements on conditional logic. If the conditional logic and the SQL statements are written in stored procedures, they become a part of a single execution plan. However, in this case if any of the stored procedure gets damaged, you may come across a number of critical database corruption situations. Corruption of the stored procedures may degrade the efficiency of MS SQL Server database and produce bad output. The function that needs to be executed using stored procedures might come down. This behavior usually makes the SQL Server database fragile. Stored procedure corruption may be indicated through a number of error message, similar to the following ones: “Error 0:[SQL-DMO]Object 'dbo.SP_ProcName' was not scripted. It is possible that the information in system table 'syscomments' about the object was corrupt or missing?” Or “Incorrect key file ... try to repair it” SQL Server database stored procedures may occur due to virus infection, improper system shutdown, application malfunction, improper command execution, and many alike. Irrespective of the cause of this problem, data loss occurs and SQL Recovery is required. You can easily Recover SQL database with the help of third-party SQL Server Recovery applications. They come equipped with highly-advanced and efficient scanning techniques to ensure absolute recovery of damaged SQL database. The software are built-with simple and self-descriptive graphical user interface to provide ease of use.

SQL database corruption can occur due to SQL Server malfunctioning, virus infection, improper system shutdown, hardware failure and many more. Once the MS SQL database gets corrupted, the SQL database become inaccessible. In such situations, use you backup, if there is no backup, the user needs to repair mdf file by using advanced SQL MDF Repair application. 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 user 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 error message encounters due to MDF file corruption. 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 MDF repair application. Such mdf file repair applications incorporate advanced and powerful scanning algorithms to repair the corrupted MDF file. The mdf recovery software perform systematic scan of corrupted MDF files, repair and restore them in their original format without altering any information.

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 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.

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 recovery software.

The SQL server Database Files is saved with the extension name of .mdf file (Master Database File). If you initiate that your database files are not accessing and moreover you are unable to open your mdf files than your files are found to be damaged. In case of MDF corruption, you may face any of the given error messages:- 1. “Windows could not start the SQL Server” 2. “MDF is not a primary database file” 3. “Server can’t find the requested database table” 4. “Database Can’t Be Accessed” 5. “The file *.mdf is missing and needs to restore” 6. “The execution of a full-text query failed”. If these types of error messages appears than its mean that your mdf file is corrupted and you need mdf repair. SQL database file gets corrupted due to unexpected system shutdown, unable to boot, invalid database file headers, internal program errors, accidental deletion of data and files, Virus attacks etc. SQL Database Recovery software uses prominent algorithm which performs a deep and broad scan of the damaged mdf file so as to retrieve each and every outline of data. MDF repair software repairs corrupted mdf file and recover table, views, stored procedures, rules and triggers from MS SQL Server effectively. There are many mdf Repair Software which scans your damage mdf files. An efficient SQL repair and recovery tool not only repair and recovers corrupt or damaged .mdf files but also repairs the entire data base without creating any limit regarding the size of the database. No matter whether the user is technically sound or not, proper guidelines and support is provided by such service providers. The mdf Repair Software is a powerful software tool that recover your data as much as possible, so to minimize the loss in file corruption and for making your organizational or personal operations productive.

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.
