When it comes to software development, there is a divide between whether to employ stored procedure or LINQ. Each option has its merits, but some key points to consider in the decision-making process are the size and scope of your development project, the skills of your coders, and your hardware.
Understanding LINQ
LINQ stands for “Language-Integrated Query,” and is a set of features that extends powerful query capabilities to the language syntax of C# and Visual Basic. LINQ is best suited for minimally invasive projects as it compiles each time it executes, and offers a compact, expressive, and lucid syntax for manipulating data.
Understanding Stored Procedure
Stored procedure is a set of “Structured Query Language” (SQL). SQL statements are given assigned names that are stored in the database in compiled form. Stored procedures are better suited for long-term projects, as they are written once, cached, used multiple times, and can be shared within more than one program.
| Advantages of LINQ |
| Tightly integrated with strongly typed data, which allows for table columns to be accessed as a property |
| LINQ is type safe, so query errors are type checked at compile time |
| LINQ is sort of a universal query language; it can work with databases, XML files, JSON files, lists, arrays, dictionaries etc. |
| Easier to debug with the use of visual studio's debugger through .NET |
| Advantages of Stored Procedure |
| SQL queries are entered in simple language |
| Directly operative features, such as encryption and decryption of data at the column level |
| Cached queries and generally better performance |
| |

|
| Disadvantages of LINQ |
| LINQ statements may seem compact on the surface, but complex queries are created under the hood |
| Processes a complete query each time it executes, which may impede performance |
| Does not directly support features like encryption and decryption, so they have to be done via other tools |
| Disadvantages of Stored Procedure |
| Difficult and time-consuming to maintain and debug |
| Difficult to port to upgraded versions of the same database. |
| Will utilize database server resources, such as memory |
|

When to choose stored procedure over LINQ
The resources and power of stored procedure are better suited for projects with complex data, while LINQ’s user-friendliness makes it more attractive for applications using CRUD. While LINQ can allow for rapid development and less maintenance, over time a project may outgrow LINQ’s limitations. Stored procedure allows for enhanced performance in handling complex projects, and while there are more roadblocks to maintenance and debugging, it is ultimately the more powerful option.
