Uses of Dynamic SQL
Dynamic SQL helps to create flexible, adaptable, and reusable SQL queries that can be applied to different scenarios and situations in fetching data from SQL Server.
Some of the general uses of Dynamic SQL are given below:
- Dynamic SQL allows to building of generic queries that can work with different tables, columns, and filtering conditions by using dynamic elements at runtime.
- Users can build dynamic queries based on user inputs and application logic to generate dynamic data and reports.
- Dynamic Filtering of Data can be done by creating dynamic SQL queries at runtime by user input for ‘WHERE’ clauses in a SQL query.
- Using the dynamic SQL queries users can sort data displayed dynamically from user interface inputs.
Dynamic SQL in SQL Server
In SQL Server, at times the SQL Queries need to be dynamic and not static, meaning the complete SQL query may be built dynamically at run time as a string using the user inputs and any specific application logic. This can be done in queries run from back-end applications or inside stored procedures. In this article let us look into the details about how to create a dynamic SQL and its uses and also what are the security issues that may arise and how to handle those security issues.
