 Choosing a distribution column is an important design decision since the values in this column determine how the rows are distributed. The best choice depends on several factors, and usually involves tradeoffs. Once a distribution column is chosen, you cannot change it.  If you didn't choose the best column the first time, you can use [CREATE TABLE AS SELECT (CTAS)](/sql/t-sql/statements/create-table-as-select-azure-sql-data-warehouse?toc=/azure/synapse-analytics/sql-data-warehouse/toc.json&bc=/azure/synapse-analytics/sql-data-warehouse/breadcrumb/toc.json&view=azure-sqldw-latest) to re-create the table with a different distribution column.
