statement pooling - Details

• 
  Key Concepts: 
  Statement pooling is a feature of the BC-JAS Java Application Server that allows for the reuse of SQL statements. This helps to reduce the amount of time and resources needed to execute a query, as the same statement can be used multiple times without having to be re-parsed and re-compiled. This can lead to improved performance and scalability. 
  
  How to use it: 
  Statement pooling is enabled by default in the BC-JAS Java Application Server. To use it, simply execute a query as you normally would. The server will then check its statement pool for an existing statement that matches the query, and if one is found, it will be reused instead of creating a new one. 
  
  Tips & Tricks: 
  When using statement pooling, it is important to ensure that the query parameters are properly set. If they are not, then the same statement may be used multiple times with different parameters, leading to incorrect results. Additionally, it is important to keep in mind that statement pooling can lead to increased memory usage, so it should be used judiciously.
