> h3. {{{}{}}}Add support for:
> Iceberg tables can be configured with a sort order that is used to automatically sort data that is written to the table in some engines. For example, {{MERGE INTO}} in Spark will use the table ordering.
> To set the write order for a table, use {{{}WRITE ORDERED BY{}}}:
>  
> {{[|https://iceberg.apache.org/docs/latest/spark-ddl/#__codelineno-31-1]CREATE TABLE prod.db.sample WRITE ORDERED BY category, id[|https://iceberg.apache.org/docs/latest/spark-ddl/#__codelineno-31-2]-- use optional ASC/DEC keyword to specify sort order of each field (default ASC)}}
> {{CREATE TABLE prod.db.sample WRITE ORDERED BY category ASC, id DESC[|https://iceberg.apache.org/docs/latest/spark-ddl/#__codelineno-31-4]-- use optional NULLS FIRST/NULLS LAST keyword to specify null order of each field (default FIRST)}}
