There are the following differences between LINQ and Stored Procedures.
- Stored procedures are faster as compared to LINQ query since they have a predictable execution plan and can take the full advantage of SQL features. Hence, when a stored procedure is being executed next time, the database used the cached execution plan to execute that stored procedure.
- LINQ has full type checking at compile-time and IntelliSense support in Visual Studio as compared to stored procedure. This powerful feature helps you to avoid run-time errors.
- LINQ allows debugging through .NET debugger as compared to stored procedure.
- LINQ also supports various .NET framework features like multi –threading as compared to stored procedures.
- LINQ provides the uniform programming model (means common query syntax) to query the multiple databases while you need to re-write the stored procedure for different databases.
- Stored procedure is a best way for writing complex queries as compared to LINQ.
- Deploying LINQ based application is much easy and simple as compared to stored procedures based. Since in case of stored procedures, you need to provide a SQL script for deployment but in case of LINQ everything gets complied into the DLLs. Hence you need to deploy only DLLs.
