EBS ORA-00911: invalid character

This error occurs when a SQL statement contains an invalid character, often due to incorrect syntax or special characters.

Understanding Oracle E-Business Suite (EBS)

Oracle E-Business Suite (EBS) is a comprehensive suite of integrated business applications designed to automate and streamline business processes. It includes modules for financials, supply chain management, human resources, and more, providing a unified platform for enterprise resource planning (ERP).

Identifying the Symptom: ORA-00911 Error

When working with Oracle EBS, you might encounter the error message: ORA-00911: invalid character. This error typically appears when executing a SQL statement that contains an invalid character, disrupting the normal execution of database operations.

Common Scenarios

This error often occurs during data entry, report generation, or when running custom SQL queries within Oracle EBS. It can halt processes and prevent successful data manipulation or retrieval.

Exploring the Issue: ORA-00911

The ORA-00911 error is triggered by the presence of an invalid character in a SQL statement. This can result from typographical errors, incorrect syntax, or the inclusion of special characters that are not recognized by the SQL parser.

Typical Causes

  • Using semicolons or other special characters within a SQL statement.
  • Incorrectly formatted SQL queries.
  • Copy-pasting SQL code from external sources with hidden characters.

Steps to Resolve ORA-00911

To resolve the ORA-00911 error, follow these steps:

1. Review the SQL Statement

Carefully examine the SQL statement for any invalid characters. Ensure that the syntax adheres to SQL standards. Remove any extraneous semicolons or special characters that are not part of the SQL syntax.

2. Validate SQL Syntax

Use a SQL syntax checker or an integrated development environment (IDE) to validate the SQL syntax. Tools like Oracle SQL Developer can help identify syntax errors and suggest corrections.

3. Check for Hidden Characters

If the error persists, check for hidden characters that may have been introduced during copy-pasting. Use a text editor that can display hidden characters, such as Notepad++, to identify and remove them.

4. Test the Query

After making corrections, test the SQL query in a controlled environment to ensure it executes without errors. This can be done using Oracle SQL Developer or a similar tool.

Conclusion

By following these steps, you can effectively diagnose and resolve the ORA-00911 error in Oracle EBS. Ensuring that your SQL statements are free from invalid characters and adhere to proper syntax will help maintain smooth database operations.
