/*建表指定表空间*/create table KC(KC_NO varchar2(10) not null,KC_NAME varchar2(50) not null) tablespace TEST;create table STU(STU_ID varchar2(10) not null,STU_NAME varchar2(50) not null,STU_AGE number(2) not null,STU_SET number(2) not null,KC_NO varchar2(10) not null) tablespace TEST;

/*创建约束，设置主键*/ALTER TABLE STU ADD PRIMARY KEY(STU_ID) ALTER TABLE KC ADD PRIMARY KEY(KC_NO) /*查看表空间的表*/Select table_name, tablespace_name from dba_tables where tablespace_name='TEST'
