db2数据库创建一张表,并为该表加上主键递增的性能和中间表的创建的sql语句
创建角色表
CREATE TABLE NBCTXP.TBL_NBC_NONBANKROLE (
ID BIGINT NOT NULL,
ROLENAME VARCHAR(50),
CREATETIME TIMESTAMP,
UPDATETIME TIMESTAMP,
CONSTRAINT P_ID PRIMARY KEY (ID)
);
CREATE INDEX SQL150130091455900 ON NBCTXP.TBL_NBC_NONBANKROLE (ID);
让主键递增1
Alter table NBCTXP.TBL_NBC_NONBANKROLE alter column ID set generated always as identity (start with 1,increment by 1)
创建角色表和用户表的中间表
CREATE TABLE NBCTXP.TBL_NBC_NONBANKUR (
USERID BIGINT NOT NULL,
ROLEID BIGINT NOT NULL,
CONSTRAINT PK_UR PRIMARY KEY (USERID,ROLEID),
CONSTRAINT FK_UID FOREIGN KEY (USERID) REFERENCES NBCTXP.TBL_NBC_NONBANKUSER(ID),
CONSTRAINT FK_RID FOREIGN KEY (ROLEID) REFERENCES NBCTXP.TBL_NBC_NONBANKROLE(ID)
);
CREATE INDEX PK_UR ON NBCTXP.TBL_NBC_NONBANKUR (USERID,ROLEID);
