[Parameter] sql_clause [Explanation] An optional pair of SQL prefix and postfix clauses organized in a list or tuple. SQL prefix supports None, DISTINCT, and TOP. SQL postfix supports None, ORDER BY, and GROUP BY. An SQL prefix clause is positioned in the first position and will be inserted between the SELECT keyword and the SELECT COLUMN LIST. The SQL prefix clause is most commonly used for clauses such as DISTINCT or ALL. An SQL postfix clause is positioned in the second position and will be appended to the SELECT statement, following the where clause. The SQL postfix clause is most commonly used for clauses such as ORDER BY. Note: This functionality is only available when working with geodatabases. Other data sources do not support it. (The default value is (None, None)) [Data Type]
