Stored procedures in MS SQL Server offer us a great deal of flexibility by which users can avoid writing queries every time for performing tasks that are typically repeated. For the uninitiated, stored procedures are nothing but queries that you can save for future use by you and others to whom you have authorized access to. Incidentally SQL Server ships with several prebuilt procedures for the perusal of its users. Now there may be incidents where an user in your organization can complain that a stored procedure that he has been authorized to access is throwing up a permission denied error message. Let’s explore the issue in detail.
Identifying the cause behind Permission Denied Errors associated with stored procedures
To start with one needs to dig deep into the stored procedure to understand the cause of the permission denied error creeping up on the user. When you grant access to a stored procedure to an user, you do not necessarily grant any rights on the underlying objects that are apparently referenced by the procedure. In some cases this mode of right access can become an impediment. For example if you have authorized an user to access a stored procedure that performs a Select action from the employee table, the user should also be given select rights on the said table. The issue can also creep up from a broken ownership chain in SQL Server. This issue can become acute when the stored procedure references objects that placed in separate databases. Without a doubt the best way to avoid the scenario involves thinking out the possible scenarios and allocating relevant permissions to respective users. One must also understand that SQL Server places these restrictions to ensure a robust security mechanism and database professionals need to appreciate advanced concepts like inheritance can get limited.
Logical Errors in SQL Server can cause a complete database crash
While there is no apparent need to fear error messages that are thrown out by the SQL Server application, it always helps to remain prepared for scenarios. Logical errors in SQL Server can at times corrupt the database altogether. In such cases you need to fall back on a powerful sql recovery tool like the reliable DataNumen SQL Recovery application. Designed to tackle the most challenging incidents of SQL corruption, the application can bring back your data, to the very last record, from views and stored procedures to functions, in perfect shape. It also demonstrates a significantly higher rate of recovery and quick completion speed than any other application in its class by a considerable margin. The tool is extremely easy to use and you can even recover a whole bunch of SQL databases in one go. Moreover the application is not restricted by the underlying physical media and can work without any apparent hassles on NDF files too.
