by

If you are encountering the ORA-01413 error in Oracle, it means that you have specified the PCTFREE option for a table or cluster more than once in the CREATE TABLE or CREATE CLUSTER statement. This can cause conflicts and prevent the creation or alteration of the table or cluster. In this article, we will discuss how to diagnose and fix this error.

Diagnosing the Error

When you encounter the ORA-01413 error, Oracle will provide you with a message that includes the table or cluster name and the conflicting PCTFREE option specifications. You can use this information to identify the source of the error.

To diagnose the error, you can review the CREATE TABLE or CREATE CLUSTER statement for the specified table or cluster. Look for any duplicate PCTFREE options and remove or correct them accordingly.

Fixing the Error

To fix the ORA-01413 error, you will need to modify the CREATE TABLE or CREATE CLUSTER statement to ensure that the PCTFREE option is specified only once.

Here are some examples of how to fix the error:

1. Remove the Duplicate PCTFREE Option
If the error is caused by a duplicate PCTFREE option, you can simply remove the duplicate specification from the CREATE TABLE or CREATE CLUSTER statement.

Example:

CREATE TABLE example_table (
  column1 NUMBER,
  column2 VARCHAR2(50)
) PCTFREE 20;

2. Correct the PCTFREE Option Specification
If the error is caused by conflicting PCTFREE options, you can correct the specification to ensure consistency.

Example:

CREATE TABLE example_table (
  column1 NUMBER,
  column2 VARCHAR2(50)
) PCTFREE 10;

3. Use ALTER TABLE to Modify PCTFREE Option
If the error occurs during the alteration of an existing table, you can use the ALTER TABLE statement to modify the PCTFREE option.

Example:

ALTER TABLE example_table
MODIFY PCTFREE 15;

Further Resources

If you require more information on the PCTFREE option and its usage, you can refer to the Oracle documentation for CREATE TABLE and CREATE CLUSTER statements. Additionally, you may find it helpful to review any relevant Oracle forums or communities for insights from other users who have encountered similar issues.

In conclusion, the ORA-01413 error in Oracle can be diagnosed and fixed by identifying and removing any duplicate or conflicting PCTFREE option specifications in the CREATE TABLE or CREATE CLUSTER statement. By following the examples and suggestions provided in this article, you can resolve this error and proceed with the creation or alteration of your table or cluster.
