• Key Concepts: 
  Fine-grained lock is a type of lock used in SAP ASE (Adaptive Server Enterprise) databases. It is a mechanism that allows multiple transactions to access the same data simultaneously, while preventing any conflicts between them. It works by granting exclusive access to a specific row or page of data, and then allowing other transactions to access the same data without any interference. 
  
  How to use it: 
  In order to use fine-grained locks, you must first enable the feature in your SAP ASE database. This can be done by setting the “lock granularity” parameter to “fine”. Once enabled, you can then use the “lock table” command to lock specific rows or pages of data. This will prevent any other transactions from accessing the same data until the lock is released. 
  
  Tips & Tricks: 
  When using fine-grained locks, it is important to remember that they are only effective when used in conjunction with other locking mechanisms such as row-level locking and page-level locking. Additionally, it is important to ensure that all transactions are properly committed or rolled back in order to avoid any deadlocks.
