Description

This error indicates that the specified precision for a datetime or interval data type is outside the allowed range of 0 to 9. It occurs when defining table columns, using functions, or performing operations involving these data types.

Error Message

ORA-30088: datetime/interval precision is out of range

🔍

Known Causes

3 known causes

⚠️

Invalid Precision Value

A datetime or interval data type was defined with a precision value outside the range of 0-9. ⚠

⚠️

Incorrect Function Argument

A function that expects a precision value for a datetime or interval was called with an invalid value. 💻

⚠️

Data Type Mismatch

An attempt was made to assign a value with an unsupported precision to a datetime or interval column. ⚠

Solutions

3 solutions available

1. Adjust Datetime/Interval Precision in Table Definitions medium

Correct invalid precision values defined for DATE, TIMESTAMP, INTERVAL types in your table schema.

1

Identify the table and column(s) causing the ORA-30088 error. This often occurs during DDL operations or data loading. You might need to review your DDL scripts or the source of the data.

2

Review the precision defined for DATE, TIMESTAMP, or INTERVAL columns. Oracle supports fractional seconds precision for TIMESTAMP types up to 9 digits. For DATE, it's typically whole seconds. For INTERVAL types, the precision refers to the fractional part of the seconds.

3

Modify the table definition to use valid precision values. For TIMESTAMP columns, this means specifying a precision between 0 and 9. For DATE, precision is implicitly whole seconds.

ALTER TABLE your_table_name MODIFY your_timestamp_column TIMESTAMP(6); -- Example for 6 digits of fractional seconds

-- For INTERVAL types, precision applies to the seconds part:
ALTER TABLE your_table_name MODIFY your_interval_column INTERVAL DAY TO SECOND(3); -- Example for 3 digits of fractional seconds

4

If the error occurs during data insertion or update, ensure the values being inserted conform to the defined precision. For example, if a TIMESTAMP column has a precision of 3, do not insert values with more than 3 fractional digits.

2. Validate Client Application's Datetime Formatting medium

Ensure the client application sending data to Oracle uses correct datetime formats and precision.

1

Examine the code in your client application (e.g., Java, Python, .NET) that interacts with the Oracle database. Pay close attention to how datetime and interval values are formatted and passed.

2

If you are using a specific date/time library in your application, consult its documentation to ensure it's configured to handle Oracle's precision requirements. Incorrect formatting or excessive fractional digits can lead to this error.

3

When binding datetime or interval parameters to SQL statements, explicitly set the precision if your driver or library allows. For example, in JDBC, you might use `setTimestamp` with a `Timestamp` object that has the desired precision.

PreparedStatement pstmt = connection.prepareStatement("INSERT INTO your_table (your_timestamp_column) VALUES (?)");
java.sql.Timestamp ts = new java.sql.Timestamp(System.currentTimeMillis());
ts.setNanos(ts.getNanos() - (ts.getNanos() % 1000000)); // Truncate to milliseconds for example
pstmt.setTimestamp(1, ts, Calendar.getInstance());
pstmt.executeUpdate();

4

Test your application with carefully crafted datetime values to isolate the problematic precision. Gradually increase the fractional digits to see where the error is triggered.

3. Review and Correct Data Loading Scripts/Tools medium

Inspect ETL scripts or data loading utilities for incorrect datetime precision handling.

1

If you're using tools like SQL*Loader, Data Pump (impdp), or third-party ETL tools to load data, examine their configuration and scripts.

2

For SQL*Loader, check the `DATE` and `TIMESTAMP` format masks in your control file. Ensure they do not specify precision beyond what the target Oracle column supports.

LOAD DATA
INFILE 'data.csv'
INTO TABLE your_table
FIELDS TERMINATED BY ','
( your_date_column DATE 'YYYY-MM-DD HH24:MI:SS',
  your_timestamp_column TIMESTAMP 'YYYY-MM-DD HH24:MI:SS.FF3' -- Ensure FF3 is appropriate for your column
)

3

When using Data Pump (impdp), review the `TRANSFORM` parameters if you are altering data types or precision during the import. Ensure the target data types and their precisions are correctly specified.

4

If you are writing custom scripts to process and load data, ensure that any datetime conversions or manipulations are consistent with the target Oracle column's defined precision.
