Explaining the Issue

The ORA-01747 error occurs when a SQL statement includes an invalid specification for a user, table, or column. This can happen due to several reasons, such as:

Using reserved keywords as identifiers without proper quoting. Incorrectly specifying table or column names. Missing or incorrect schema qualification.

For more details on Oracle SQL syntax, refer to the Oracle SQL Reference Guide.

Steps to Fix the Issue

To resolve the ORA-01747 error, follow these steps:

Step 1: Review the SQL Statement

Carefully examine the SQL statement for any syntax errors or incorrect specifications. Ensure that all identifiers are correctly spelled and properly qualified.

Step 2: Check for Reserved Keywords

If any table or column names match Oracle's reserved keywords, enclose them in double quotes. For example:

SELECT "SELECT", "FROM" FROM my_table;

Refer to the list of Oracle reserved words for guidance.

Step 3: Verify Schema Qualification

Ensure that the table and column names are correctly qualified with the schema name if necessary. For example:

SELECT column_name FROM schema_name.table_name;

Step 4: Test the Corrected Query

After making the necessary corrections, execute the SQL statement again to verify that the error is resolved. If the issue persists, double-check the query for any overlooked errors.

Conclusion

By following these steps, you can effectively diagnose and resolve the ORA-01747 error in Oracle EBS. Ensuring correct SQL syntax and proper specification of identifiers is crucial for maintaining smooth database operations. For further assistance, consult the Oracle Support portal.
