Executing SQL Queries from Text Files in Java

When working with Java applications that interact with databases, you often need to execute SQL queries. While it's common to embed queries directly in your code, storing them in text files offers benefits such as easier maintenance and version control. In this guide, we'll explore how to execute SQL queries from text files in Java.

Java Code to Execute Queries

Now, let's write a Java program to read the SQL queries from the file and execute them using JDBC (Java Database Connectivity). Make sure you have the JDBC driver for your database installed and added to your project.

Explanation

The program establishes a connection to the database using the JDBC driver.

The queries are split based on semicolons (;) since multiple queries can be present in the file.

The program then executes each query using the execute method of the Statement object.

Conclusion

Executing SQL queries from text files in Java can enhance code organization and make it easier to manage database interactions. By following the steps outlined in this guide, you can seamlessly integrate SQL queries from text files into your Java applications.
