How Can I Dynamically Select Column Names in SQL Using Variables?

Dynamic Column Name Selection in SQL Using Variables

The given SQL statement attempts to select a value with a column name derived from a passed variable, but it encounters syntax errors. This article aims to provide a solution for this issue, enabling the dynamic selection of column names based on variables.

The provided code demonstrates the need to select a value using a dynamic column name, which is not directly supported by SQL. However, a workaround is possible using dynamic SQL, as seen in the answer:

EXEC ('SELECT ''value'' AS ' + @myDynamicColumn)

This code constructs a dynamic SQL statement using the variable @myDynamicColumn to create the desired column name. It executes this dynamic SQL statement, effectively selecting the value as the column name defined by the variable.

It's important to note that while dynamic SQL provides flexibility, it also introduces potential security risks. It's essential to sanitize user input and carefully craft dynamic SQL statements to prevent malicious code injection.
