Description

The ORA-30182 error indicates an issue with the format specification used in a SQL query or PL/SQL code. Specifically, it means that a period (.) used to specify precision in a format mask is not followed by a valid format element, such as a number (e.g., '9').

Error Message

ORA-30182: invalid precision specifier

🔍

Known Causes

3 known causes

⚠️

Incorrect Format String

The format string used in functions like `TO_CHAR` or `TO_NUMBER` contains a period (.) not followed by a valid numerical format specifier.

⚠️

Typographical Error

A typo in the format string resulted in a period being placed without an associated precision value.

⚠️

Missing Precision Value

The intended precision value after the period was accidentally omitted from the format mask.

Solutions

3 solutions available

1. Correct Data Type Precision in CREATE TABLE or ALTER TABLE Statement easy

Adjust the precision value for numeric data types to be within valid Oracle limits.

1

Identify the table and column causing the ORA-30182 error. This usually occurs when creating a new table or altering an existing one.

2

Examine the data type definition for the problematic column. For numeric types like `NUMBER`, the precision is the total number of digits, and scale is the number of digits after the decimal point. Oracle `NUMBER` precision can range from 1 to 38.

Example of an invalid precision: `NUMBER(40)`

3

Modify the `CREATE TABLE` or `ALTER TABLE` statement to use a valid precision. The maximum precision for `NUMBER` is 38. If you need more precision, consider alternative solutions or re-evaluating the data requirements.

-- For CREATE TABLE:
CREATE TABLE my_table (
    id NUMBER(10),
    value NUMBER(38, 5) -- Valid precision and scale
);

-- For ALTER TABLE:
ALTER TABLE my_table MODIFY (value NUMBER(30, 2)); -- Adjusting to a valid precision

2. Review and Correct Precision in Application Code or Scripts medium

Ensure that any SQL statements generated or executed by application code or scripts use valid precision values.

1

If the error occurs during application runtime, review the application code that interacts with the database. Look for SQL statements that define or manipulate numeric data types.

2

Search for occurrences of `NUMBER` data types with precision specifiers that exceed the Oracle limit of 38. This could be in stored procedures, functions, ORM configurations, or direct SQL queries.

Example in application logic (conceptual):
String sql = "CREATE TABLE temp_data (amount NUMBER(45));"; // Invalid precision
// Or within a stored procedure definition...

3

Correct the precision in the application code or script to be within the valid range (1-38 for `NUMBER`).

-- Corrected example:
String sql = "CREATE TABLE temp_data (amount NUMBER(38, 2));";

4

Recompile or redeploy the application code or execute the corrected script.

3. Validate Precision in Data Loading Tools medium

Check precision settings in tools used for data import/export to prevent ORA-30182.

1

If you are using data loading tools (e.g., SQL*Loader, Data Pump, third-party ETL tools) and encountering this error, examine the tool's configuration or control files.

2

Look for definitions of numeric columns in the data loading configuration. Ensure that the specified precision for any `NUMBER` data type being loaded into Oracle is valid (1-38).

Example in a SQL*Loader control file:
LOAD DATA
INFILE 'data.csv'
INTO TABLE my_table
FIELDS TERMINATED BY ','
(
    id NUMBER(10),
    amount NUMBER(40) -- This would cause ORA-30182
)

3

Adjust the precision in the control file or tool's mapping to be within the valid Oracle range.

-- Corrected SQL*Loader control file:
(
    id NUMBER(10),
    amount NUMBER(38, 2) -- Valid precision and scale
)

4

Re-run the data loading process with the corrected configuration.
