# SQLSTATE KD00E

**SQLSTATE KD00E** is a Databricks-specific error class that belongs to the `KD` SQLSTATE class, which covers datasource-specific errors. This SQLSTATE is assigned to the `DELTA_ICEBERG_WRITER_COMPAT_VIOLATION` error condition, which indicates that validation of the `IcebergWriterCompatV<version>` table feature has failed during a Delta table operation. The feature enforces Apache Iceberg writer compatibility rules on Delta Lake tables. ^[delta_iceberg_writer_compat_violation-error-condition-databricks-on-aws.md]

## Error Condition: DELTA_ICEBERG_WRITER_COMPAT_VIOLATION

This error condition occurs when an operation on a Delta table violates one of the constraints required by the `IcebergWriterCompatV<version>` table feature. Each violation has a specific sub‑type with its own error message describing the compatibility rule that was broken. ^[delta_iceberg_writer_compat_violation-error-condition-databricks-on-aws.md]

### Sub‑types

The following sub‑types are defined for `DELTA_ICEBERG_WRITER_COMPAT_VIOLATION`:

| Sub‑type | Description |
|----------|-------------|
| `CANNOT_CHANGE_MAP_STRUCT_KEY` | The transaction attempts to change a map key that is a struct, which is disallowed. |
| `CONFIG_NOT_ENABLED` | A required configuration (`<config>`) is not enabled. |
| `DISABLING_REQUIRED_TABLE_FEATURE` | An attempt to drop a table feature (`<feature>`) that is required to be supported and enabled. |
| `FIELD_ID_DOES_NOT_MATCH_PHYSICAL_NAME` | Column mapping field physical names do not follow the required `col-[fieldId]` pattern. |
| `INCOMPATIBLE_TABLE_FEATURE` | A table feature (`<feature>`) is incompatible with the current compatibility version. |
| `MISSING_REQUIRED_TABLE_FEATURE` | A table feature (`<feature>`) that must be supported and enabled is missing. |
| `UNSUPPORTED_DATA_TYPE` | The schema contains a data type (`<dataType>`) not supported by the compatibility version. |
| `UNSUPPORTED_ICEBERG_TABLE_PROPERTY` | An Apache Iceberg table property (`<key>`) is not supported. |
| `WRONG_REQUIRED_TABLE_PROPERTY` | A required table property (`<key>`) is set to an incorrect value (`<actualValue>`) instead of the required value (`<requiredValue>`). |

## Common Causes

Common causes of a `KD00E` error include:

- Changing a struct‑typed key in a map column.
- Disabling or dropping a table feature that the compatibility version requires.
- Using a data type in the schema that is unsupported by `IcebergWriterCompatV<version>`.
- Setting an Apache Iceberg table property that is not supported by the compatibility version.
- Setting a required table property to an incorrect value.
- Having column mapping field names that do not match the expected `col-[fieldId]` pattern.
- Attempting to use a table feature that is incompatible with the current compatibility version.
- Not enabling a configuration that is required by the compatibility version.

## Resolution

Resolution depends on the specific sub‑type. In general, you must modify the operation or the table metadata to comply with the `IcebergWriterCompatV<version>` rules:

- Re‑enable any required configuration (`CONFIG_NOT_ENABLED`).
- Restore or enable any required table feature (`MISSING_REQUIRED_TABLE_FEATURE`, `DISABLING_REQUIRED_TABLE_FEATURE`).
- Remove or replace unsupported data types or table properties (`UNSUPPORTED_DATA_TYPE`, `UNSUPPORTED_ICEBERG_TABLE_PROPERTY`).
- Correct the value of a required table property (`WRONG_REQUIRED_TABLE_PROPERTY`).
- Adjust column mapping physical names to follow the `col-[fieldId]` pattern (`FIELD_ID_DOES_NOT_MATCH_PHYSICAL_NAME`).
- Avoid changing struct‑typed map keys or using incompatible table features.
