EBS ORA-01403: no data found

What is EBS ORA-01403: no data found

Understanding Oracle E-Business Suite (EBS)

Oracle E-Business Suite (EBS) is a comprehensive suite of integrated business applications designed to help enterprises manage their business processes. It includes modules for financials, supply chain management, human resources, and more. EBS is widely used for its robust functionality and scalability, making it a popular choice for large organizations.

Identifying the Symptom: ORA-01403 Error

When working with Oracle EBS, you may encounter the error code ORA-01403: no data found. This error typically arises during the execution of a PL/SQL block, particularly when a SELECT INTO statement is used. The symptom is that the expected data is not retrieved, leading to an interruption in the process.

Common Scenarios

This error is commonly observed in scenarios where the application expects a single row of data to be returned, but the query does not find any matching records in the database.

Details About the ORA-01403 Issue

The ORA-01403: no data found error occurs when a SELECT INTO statement fails to return any rows. In Oracle PL/SQL, a SELECT INTO statement is used to fetch data into variables. If the query does not find any data, Oracle raises this exception.

Why It Happens

This error is raised because Oracle expects the SELECT INTO statement to return exactly one row. If no rows are found, the exception is triggered, indicating that the data retrieval was unsuccessful.

Steps to Fix the ORA-01403 Error

To resolve the ORA-01403: no data found error, follow these steps:

Step 1: Verify the Query

Ensure that the query used in the SELECT INTO statement is correct. Check the table name, column names, and any conditions applied in the WHERE clause. Make sure that the data you expect to retrieve actually exists in the database.

Step 2: Use Exception Handling

Implement exception handling in your PL/SQL block to gracefully handle the ORA-01403 error. Use the EXCEPTION block to catch the error and take appropriate action, such as logging the error or providing a default value.

BEGIN SELECT column_name INTO variable_name FROM table_name WHERE condition;EXCEPTION WHEN NO_DATA_FOUND THEN -- Handle the exception DBMS_OUTPUT.PUT_LINE('No data found.');END;

Step 3: Use Cursor for Multiple Rows

If there is a possibility of retrieving multiple rows, consider using a cursor instead of SELECT INTO. Cursors allow you to fetch multiple rows and process them one at a time.

DECLARE CURSOR c IS SELECT column_name FROM table_name WHERE condition; variable_name table_name.column_name%TYPE;BEGIN OPEN c; FETCH c INTO variable_name; IF c%NOTFOUND THEN DBMS_OUTPUT.PUT_LINE('No data found.'); END IF; CLOSE c;END;
