How Can I Use Parameters to Specify File Paths When Creating a Database in SQL?

Using Parameters in CREATE DATABASE

In a recent SQL script, you attempted to specify the path for creating data and log files using parameters. However, you encountered an error due to incorrect syntax near '@DataFilePath.' Let's explore the issue and provide a viable solution.

Parameter Usage in CREATE DATABASE

The syntax for CREATE DATABASE does not support direct parameter usage. To overcome this limitation, dynamic SQL can be employed.

Dynamic SQL

Dynamic SQL allows you to construct SQL statements at runtime using a string variable (@sql). By concatenating path values into @sql, you can create a parameterized CREATE DATABASE statement.

Corrected Script

Parameterized Path Values

The QUOTENAME() function ensures that path values are properly quoted for use in the SQL statement. This prevents errors caused by special characters or spaces in the path.

By utilizing dynamic SQL and parameterized path values, you can successfully specify the filepaths for your database and log files in a SQL script using parameters.
