Question

在没有ENUM的情况下创建表的成功，我得到了这个例外在Java中使用Derby数据库

Statement stmt = con.createStatement();
String sql = "CREATE TABLE Coupon (ID BIGINT, TITLE VARCHAR(100), START_DATE DATE, END_DATE DATE, AMOUNT INTEGER, "
+ " TYPE ENUM('Electronics','Health','Beauty','Restaurants','Leisure','Travel'),"
+ " MESSAGE VARCHAR(40), PRICE DOUBLE, IMAGE VARCHAR(100),PRIMARY KEY(ID))";
stmt.executeUpdate(sql);

例外：

java.sql.SQLSyntaxErrorException: Syntax error: Encountered "(" at line 1, column 113.

尝试使用此查询添加size代替type，如下所示：

 String sql = "CREATE TABLE Coupon (ID BIGINT, TITLE VARCHAR(100), START_DATE DATE, END_DATE DATE, AMOUNT INTEGER, "
 + " size ENUM('Electronics','Health','Beauty','Restaurants','Leisure','Travel'),"
 + " MESSAGE VARCHAR(40), PRICE DOUBLE, IMAGE VARCHAR(100),PRIMARY KEY(ID))";

创建具有ENUM的表时JDBC中的SQL语法错误
