How Can I Execute a MySQL .sql Script Using JDBC?

Streamlining MySQL Database Setup with JDBC and ScriptRunner

JDBC offers a powerful way to interact with MySQL databases. However, manually creating multiple tables using individual JDBC statements can be cumbersome. This article demonstrates a more efficient approach: executing entire .sql scripts directly via JDBC.

The Solution: Leveraging ScriptRunner

The key to efficient script execution is the ScriptRunner class. This utility simplifies the process of running SQL scripts within your JDBC code. Here's how:

1. Establish a Database Connection: Obtain your JDBC Connection object (conn) using standard JDBC connection methods.

2. Instantiate ScriptRunner: Create a ScriptRunner instance, specifying parameters for auto-commit behavior and error handling:

   ScriptRunner runner = new ScriptRunner(conn, false, false); // false for both autoCommit and stopOnError

3. Execute the Script: Use the runScript() method to execute your .sql file:

   runner.runScript(new BufferedReader(new FileReader("test.sql")));

This concise code snippet executes all SQL commands within "test.sql". This method drastically reduces code complexity compared to manually executing each SQL statement. The ScriptRunner handles the parsing and execution, streamlining your database setup process.
