Description

The ORA-30073 error indicates an invalid adjustment value was provided when configuring date or timestamp adjustments within the Oracle database. This typically occurs when setting parameters or using functions that require a specific date/timestamp adjustment option.

Error Message

ORA-30073: invalid adjustment value

🔍

Known Causes

3 known causes

⚠️

Incorrect Adjustment Value

The specified adjustment value is not one of the allowed options: 'ADJUST', 'NO_ADJUST', or 'ANSI_DATE', 'ADJUST_WITH_ANSI_DATE'.

⚠️

Typographical Error

A typographical error exists in the adjustment value string (e.g., 'ADJST' instead of 'ADJUST').

⚠️

Case Sensitivity Issue

The adjustment value is specified using the wrong case (e.g., 'adjust' instead of 'ADJUST' when case sensitivity is enforced).

Solutions

3 solutions available

1. Verify and Correct Data Type in INSERT/UPDATE Statements easy

Ensure that numeric or date values being inserted or updated are of the correct data type and format.

1

Identify the SQL statement (INSERT or UPDATE) that is causing the ORA-30073 error. This usually involves reviewing recent code changes or tracing the session encountering the error.

2

Examine the values being provided for columns that expect numeric or date/timestamp data types. Pay close attention to any implicit conversions or incorrect formatting.

Example of incorrect format:
INSERT INTO my_table (numeric_column) VALUES ('123.45ABC');

Example of incorrect format for dates:
INSERT INTO my_table (date_column) VALUES ('2023-13-01'); -- Invalid month
INSERT INTO my_table (date_column) VALUES ('01/31/2023 25:00:00'); -- Invalid hour

3

Correct the data type or format of the values to match the target column's definition. Use explicit conversions (e.g., TO_NUMBER, TO_DATE) if necessary, ensuring the format mask is accurate.

Corrected example:
INSERT INTO my_table (numeric_column) VALUES (123.45);

Corrected date example:
INSERT INTO my_table (date_column) VALUES (TO_DATE('2023-12-01', 'YYYY-MM-DD'));
INSERT INTO my_table (timestamp_column) VALUES (TO_TIMESTAMP('2023-01-31 14:30:00', 'YYYY-MM-DD HH24:MI:SS'));

2. Review Application Logic for Data Validation medium

Check application code that prepares data for database operations to ensure proper validation and formatting.

1

Analyze the application code responsible for generating the SQL statements that are failing. This could be in PL/SQL, Java, Python, or any other language interacting with Oracle.

2

Identify any points where data is read, transformed, or validated before being passed to the database. Look for potential issues with numeric parsing, date formatting, or handling of special characters.

Example in Java (conceptual):
String userInput = request.getParameter("value");
// Potential issue: If userInput is not purely numeric and contains non-digit characters
BigDecimal dbValue = new BigDecimal(userInput);
// This could throw a NumberFormatException if userInput is invalid, leading to ORA-30073 if not handled.

3

Implement robust data validation within the application to ensure that only valid numeric, date, or other data types are constructed before being sent to the database. Use appropriate try-catch blocks for parsing operations.

Example in Java (improved):
String userInput = request.getParameter("value");
BigDecimal dbValue = null;
try {
    dbValue = new BigDecimal(userInput);
    // Proceed with database operation using dbValue
} catch (NumberFormatException e) {
    // Handle the error: inform user, log, or use a default value
    throw new IllegalArgumentException("Invalid numeric input: " + userInput);
}

4

If dealing with dates, ensure the application consistently uses a recognized date format that matches the database's NLS_DATE_FORMAT or is explicitly converted using TO_DATE with the correct format mask.

3. Investigate NLS_DATE_FORMAT and NLS_NUMERIC_CHARACTERS Settings medium

Understand and align database or session settings for date and numeric formatting with the data being processed.

1

Check the `NLS_DATE_FORMAT` and `NLS_NUMERIC_CHARACTERS` parameters for your Oracle database or session. These parameters define how dates and numbers are interpreted.

SELECT parameter, value FROM v$nls_parameters WHERE parameter IN ('NLS_DATE_FORMAT', 'NLS_NUMERIC_CHARACTERS');

2

If the data being inserted or updated uses a format that does not match the current `NLS_DATE_FORMAT` (e.g., 'MM/DD/YYYY' vs. 'DD-MON-YY'), you have two options:

1. **Modify the application:** Ensure the application uses `TO_DATE` with the correct format mask when inserting dates. This is the preferred approach for clarity and portability.
2. **Change NLS settings (use with caution):** Temporarily or permanently alter the NLS parameters. This can affect many applications, so it's generally not recommended unless you have full control and understanding of the impact.

Option 1 (preferred):
INSERT INTO my_table (date_column) VALUES (TO_DATE('01/31/2023', 'MM/DD/YYYY'));

Option 2 (session level, use with caution):
ALTER SESSION SET NLS_DATE_FORMAT = 'MM/DD/YYYY';

3

Similarly, for numeric values, ensure that the decimal separator and group separator defined in `NLS_NUMERIC_CHARACTERS` match the data. For example, if `NLS_NUMERIC_CHARACTERS` is '.,' (decimal point, comma group separator) and you're trying to insert '1,234.56', it might cause issues if the application or database expects '1.234,56'.

Example with specific numeric characters:
-- Assuming NLS_NUMERIC_CHARACTERS is set to '.,' (decimal point is '.', group separator is ',')
INSERT INTO my_table (numeric_column) VALUES (1234.56);

-- If NLS_NUMERIC_CHARACTERS was '.,':
-- INSERT INTO my_table (numeric_column) VALUES ('1.234,56'); -- This would be interpreted as 1234.56

-- If NLS_NUMERIC_CHARACTERS was ',.':
-- INSERT INTO my_table (numeric_column) VALUES ('1,234.56'); -- This would be interpreted as 1234.56
