4 Best Practises for Faster Stored Procedure Execution

Like a well-oiled machine, optimising stored procedures for speed and efficiency is crucial for database performance.

In this article, we delve into the top 4 best practises for faster stored procedure execution.

From indexing strategies to query plan analysis, these practises are essential for streamlining database operations and improving overall system performance.

Mastering these techniques can significantly enhance the execution speed of stored procedures, leading to a more responsive and agile database environment.

Key Takeaways

  • Proper indexing strategies enhance the performance of stored procedures.
  • Parameter optimisation plays a pivotal role in efficient execution.
  • Avoiding cursor usage can improve performance.
  • Regularly analysing the query execution plan can optimise performance.

Indexing for Performance

When optimising stored procedure execution for speed, indexing for performance is essential. Proper indexing strategies play a crucial role in enhancing the performance of stored procedures.

Performance tuning through indexing involves strategically organising and structuring the data in the database to minimise the query execution time. One of the key aspects of indexing is to identify the columns frequently used in the WHERE and JOIN clauses and create indexes on these columns. This enables the database engine to quickly locate the required rows, thereby improving the overall performance of the stored procedures.

Additionally, it’s important to consider the selectivity of the columns when creating indexes. Columns with high selectivity are ideal candidates for indexing as they allow the database engine to efficiently filter and retrieve data.

Careful consideration of the appropriate indexing strategies based on the specific usage patterns and query requirements is paramount. It’s essential to strike a balance between the number of indexes and the performance benefits, as an excessive number of indexes can degrade performance due to increased overhead on data modification operations.

Therefore, a meticulous approach to performance tuning through indexing is vital for achieving faster stored procedure execution.

Parameter Optimisation

Indexing for performance is crucial, and parameter optimisation plays a pivotal role in enhancing the efficiency of stored procedure execution. When it comes to parameter optimisation, one important aspect to consider is parameter caching. By caching execution plans for stored procedures that use parameters, the database engine can reuse the plans for similar parameter values, reducing the overhead of generating execution plans and improving overall performance.

Another key element of parameter optimisation is input validation. Proper validation of input parameters helps prevent SQL injection attacks and ensures that only valid and expected values are processed by the stored procedure. This not only enhances security but also improves performance by preventing unnecessary execution of potentially harmful or inefficient queries.

Avoiding Cursor Usage

To further optimise the performance of stored procedures, developers should consider adopting a set-based approach for data retrieval and result set manipulation. By leveraging set-based operations, such as using SELECT, UPDATE, and DELETE statements, performance improvements can be achieved when compared to cursor-based processing. This approach allows for handling data as a whole, rather than processing individual rows sequentially, leading to faster execution times and reduced resource consumption.

To mitigate the negative impact of cursors on performance, developers should avoid using them altogether. Instead, they should embrace a set-based mindset and explore alternative methods for data manipulation. One such method is to utilise temporary tables or table variables to store intermediate results. By doing so, developers can avoid the row-by-row processing nature of cursors and improve performance.

Query Execution Plan Analysis

Regularly analysing the query execution plan is essential for optimising the performance of stored procedures. By examining the execution plan, developers can identify potential bottlenecks and inefficiencies in the queries, allowing for performance tuning and execution plan optimisation.

Here are some key points to consider when analysing the query execution plan:

Index Usage: Cheque if the appropriate indexes are being utilised in the execution plan.

Table Scans: Look for instances where table scans are being performed instead of utilising indexes.

Join Operations: Analyse how the join operations are being executed and whether they are optimal.

Filtering: Evaluate how the filtering of data is being handled in the execution plan.

Resource Utilisation: Assess the consumption of resources such as CPU, memory, and I/O during query execution.


In conclusion, implementing best practises such as indexing for performance, parameter optimisation, avoiding cursor usage, and analysing query execution plans can significantly improve the execution speed of stored procedures.
