Develop your data access layer using safe parameterized queries

One of the biggest concerns I face as a developer when writing SQL queries in my application is how to make them safe so that they are not prone to SQL injection attacks and at the same time they execute efficiently. Most developers go the route of putting all their queries as stored procedures in the database to handle the security and performance concern. Although this is a viable solution, it splits your application code in multiple places making it difficult to read, maintain and debug.
