Introduction

When migrating a Spring Boot application to version 3.X, you may encounter various issues, especially when interacting with a DB2 database. One such issue is the DB2 SQL error with the code SQLCODE=-104, SQLSTATE=42601, and SQLERRMC=);.LAST_NAME) in((?,?,?);<is_not_null_token>, DRIVER=4.25.13. This error can be frustrating, especially when you're not familiar with the intricacies of DB2 or the changes introduced in Spring Boot 3.X.

Understanding the Error

The error message indicates that there's a problem with the SQL statement being executed. The SQLCODE=-104 suggests that the error is related to the syntax of the SQL statement. The SQLSTATE=42601 indicates that the error is a syntax error, and the SQLERRMC=);.LAST_NAME) in((?,?,?);<is_not_null_token> provides more information about the specific part of the SQL statement that's causing the error.

Causes of the Error

There are several reasons why you might encounter this error when inserting records into a DB2 database using Spring Boot 3.X. Some possible causes include:

  • Incorrect SQL syntax: The SQL statement being executed may contain incorrect syntax, such as missing or extra parentheses, or incorrect use of operators.
  • DB2 database configuration: The DB2 database may be configured in a way that's not compatible with the Spring Boot 3.X application.
  • Hibernate or Spring Data JPA configuration: The Hibernate or Spring Data JPA configuration may be incorrect, leading to the error.

Solution to the Error

To resolve the DB2 SQL error, you'll need to identify the root cause of the issue and make the necessary corrections. Here are some steps you can follow:

Step 1: Review the SQL Statement

Carefully review the SQL statement being executed to ensure that it's correct and free of syntax errors. Check for missing or extra parentheses, and ensure that the operators are used correctly.

Step 2: Check the DB2 Database Configuration

Verify that the DB2 database is configured correctly and that the configuration is compatible with the Spring Boot 3.X application. Check the DB2 database connection properties, such as the database name, username, password, and driver version.

Step 3: Review the Hibernate or Spring Data JPA Configuration

Check the Hibernate or Spring Data JPA configuration to ensure that it's correct and compatible with the DB2 database. Verify that the configuration includes the correct database driver, dialect, and other settings.

Step 4: Update the Spring Boot Version

If you're using an older version of Spring Boot, consider updating to the latest version (3.X) to take advantage of the latest features and bug fixes.

Step 5: Use a Debugger or Logging Tool

Use a debugger or logging tool to gain more insight into the issue. This can help you identify the specific part of the code that's causing the error.

Example Use Case

Here's an example use case that demonstrates how to resolve the DB2 SQL error:

// Emp.java
@Data
@Entity
@Table(name = "emp")
public class Emp {

@EmbeddedId
private EmpId id;


@Column(name = "first_name")
private String firstName;


@Column(name = "last_name")
private String lastName;


// Getters and setters
}


// EmpId.java
@Data
@Embeddable
public class EmpId implements Serializable {


@Column(name = "employee_id")
private Long employeeId;


@Column(name = "department_id")
private Long departmentId;


// Getters and setters
}


// EmpRepository.java
public interface EmpRepository extends JpaRepository<Emp, EmpId> {


// Custom queries
}


// EmpService.java
@Service
public class EmpService {


@Autowired
private EmpRepository empRepository;


public void saveEmp(Emp emp) {
empRepository.save(emp);
}
}

In this example, the Emp entity has an embedded ID EmpId that contains two columns: employee_id and department_id. The EmpRepository interface extends JpaRepository and provides custom queries for the Emp entity. The EmpService class uses the EmpRepository to save an Emp object.

Conclusion

The DB2 SQL error with the code SQLCODE=-104, SQLSTATE=42601, and SQLERRMC=);.LAST_NAME) in((?,?,?);<is_not_null_token>, DRIVER=4.25.13 can be frustrating, but it's often a simple syntax error or configuration issue. By following the steps outlined in this article, you should be able to identify and resolve the issue. Remember to review the SQL statement, check the DB2 database configuration, review the Hibernate or Spring Data JPA configuration, update the Spring Boot version, and use a debugger or logging tool to gain more insight into the issue.
