对于 SQL DDL 代码，答案是否定的.ACE/Jet SQL 没有任何流程控制语法，一个 ACE/Jet PROCEDURE 只能执行一个 SQL 语句.是的，没错:ACE/Jet PROCEDURE 不支持程序代码 :(

For SQL DDL code the answer is no. ACE/Jet SQL does not have any control-of-flow syntax and a ACE/Jet PROCEDURE can only execute one SQL statement. Yes, that's right: an ACE/Jet PROCEDURE does not support procedural code :(
