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, enabling organizations to manage their operations efficiently.
When working with Oracle EBS, you might encounter the error code ORA-00904: invalid identifier. This error typically surfaces when executing a SQL statement that references an invalid column name or alias. The error message can be frustrating, especially when dealing with complex queries.
The ORA-00904 error is a common SQL error that indicates an issue with the identifier used in a SQL statement. In Oracle databases, identifiers refer to names of database objects such as tables, columns, and aliases. If the database cannot recognize an identifier, it throws the ORA-00904 error.
This error occurs due to one of the following reasons:
To resolve the ORA-00904 error, follow these steps:
Ensure that all column names in your SQL statement are spelled correctly and exist in the table. You can query the USER_TAB_COLUMNS view to list all columns in a table:
SELECT column_name FROM user_tab_columns WHERE table_name = 'YOUR_TABLE_NAME';
Review your SQL statement for any aliases used. Ensure that aliases are defined correctly and used consistently throughout the query.
Examine the SQL syntax for any errors. Ensure that all identifiers are properly quoted if they contain special characters or are case-sensitive.
If the issue persists, consult the Oracle SQL Reference Guide for detailed information on SQL syntax and usage.
By carefully reviewing your SQL statements and ensuring that all identifiers are valid, you can effectively resolve the ORA-00904 error. For more complex issues, consider reaching out to Oracle support or consulting additional resources such as the Oracle Community.
