CREATE TABLE s_dept
(id       VARCHAR(3)  CONSTRAINT s_dept_id_nn NOT NULL,
name    VARCHAR(20) CONSTRAINT s_dept_name_nn NOT NULL,
region_id  VARCHAR(3),
CONSTRAINT s_dept_id_pk PRIMARY KEY (id),
CONSTRAINT s_dept_name_region_id_uk UNIQUE (name, region_id)
);

我在db2中执行报错：

valid Command Line Processor command.  During SQL processing it returned:

SQL0104N  An unexpected token "NOT NULL" was found following

"<col_constraint_name_defn>;".  Expected tokens may include:  "FOREIGN KEY,

PRIMARY KEY, CHECK".  SQLSTATE=42601

不知道怎么回事，请高手指点

请问这个SQL语法有没有错误？

CREATE TABLE s_dept
(id VARCHAR(3) NOT NULL,
name VARCHAR(20) NOT NULL,
region_id VARCHAR(3),
CONSTRAINT s_dept_id_pk PRIMARY KEY (id),
CONSTRAINT s_dept_name_region_id_uk UNIQUE (name, region_id)
);
