# UNRESOLVED_COLUMN error subtype

The **UNRESOLVED_COLUMN error subtype** is a specific error within the [`DELTA_UNSUPPORTED_CLUSTERING_COLUMN_PREDICATES` error class](https://docs.databricks.com/aws/en/error-messages/delta-unsupported-clustering-column-predicates-error-class) (SQLSTATE: 0A000). It occurs when a command issued on a [Liquid table](/concepts/liquid-tables.md) contains a predicate that references a column that cannot be matched to any of the table's clustering columns. ^[delta_unsupported_clustering_column_predicates-error-condition-databricks-on-aws.md]

## Error Message

The error message follows this pattern:

```
Fail to resolve column '<columnName>' in <command> predicate. Available clustering columns: [<columnList>].
```

Where `<columnName>` is the unresolved column, `<command>` is the operation being performed, and `<columnList>` lists the clustering columns that are recognized. ^[delta_unsupported_clustering_column_predicates-error-condition-databricks-on-aws.md]

## Cause

Liquid tables support certain commands (e.g., `DELETE`, `UPDATE`, `MERGE`) only on their [Clustering columns](/concepts/clustering-columns.md). If a predicate in such a command references a column that does not exist in the table's clustering column list, the system cannot resolve it because only clustering columns are allowed in that context. ^[delta_unsupported_clustering_column_predicates-error-condition-databricks-on-aws.md]

## Context

This error subtype is part of the broader [`DELTA_UNSUPPORTED_CLUSTERING_COLUMN_PREDICATES`](https://docs.databricks.com/aws/en/error-messages/delta-unsupported-clustering-column-predicates-error-class) error class, which includes other subtypes like `NON_CLUSTERING_COLUMN`, `NO_CLUSTERING_COLUMNS`, and `UNSUPPORTED_EXPRESSION`. All relate to restrictions on predicates used with Liquid tables. ^[delta_unsupported_clustering_column_predicates-error-condition-databricks-on-aws.md]

## Resolution

Ensure that any predicate in the command references only columns that are listed as clustering columns. If the intended column is not a clustering column, consider changing the command (e.g., using a different approach) or modifying the table's clustering columns if appropriate. ^[delta_unsupported_clustering_column_predicates-error-condition-databricks-on-aws.md]
