用sql语句创建数据库Student(Sno,Sname, Ssex, Sage,Sdept) SC(Sno,Cno,Grade) C(Cno,Cname,Cpno,Ccredit)并且给我插入一点数据

好的，以下是创建数据库Student、SC、C的SQL语句：

CREATE DATABASE Student;

USE Student;

CREATE TABLE Student(
  Sno VARCHAR(10) PRIMARY KEY,
  Sname VARCHAR(20) NOT NULL,
  Ssex CHAR(2) CHECK(Ssex='男' OR Ssex='女'),
  Sage INT CHECK(Sage>=18 AND Sage<=35),
  Sdept VARCHAR(20) NOT NULL
);

CREATE TABLE C(
  Cno VARCHAR(10) PRIMARY KEY,
  Cname VARCHAR(20) NOT NULL,
  Cpno VARCHAR(10),
  Ccredit FLOAT CHECK(Ccredit>=1 AND Ccredit<=5)
);

CREATE TABLE SC(
  Sno VARCHAR(10),
  Cno VARCHAR(10),
  Grade FLOAT CHECK(Grade>=0 AND Grade<=100),
  PRIMARY KEY(Sno, Cno),
  FOREIGN KEY(Sno) REFERENCES Student(Sno),
  FOREIGN KEY(Cno) REFERENCES C(Cno)
);

插入数据：

INSERT INTO Student VALUES('01', '张三', '男', 20, '计算机科学与技术');
INSERT INTO Student VALUES('02', '李四', '男', 19, '软件工程');
INSERT INTO Student VALUES('03', '王五', '女', 21, '信息管理');

INSERT INTO C VALUES('01', '数据库', NULL, 3.0);
INSERT INTO C VALUES('02', '数据结构', NULL, 4.0);
INSERT INTO C VALUES('03', '操作系统', '01', 4.5);

INSERT INTO SC VALUES('01', '01', 90.0);
INSERT INTO SC VALUES('01', '02', 85.0);
INSERT INTO SC VALUES('02', '01', 70.0);
INSERT INTO SC VALUES('02', '02', 80.0);
INSERT INTO SC VALUES('03', '01', 95.0);
INSERT INTO SC VALUES('03', '02', 90.0);
INSERT INTO SC VALUES('03', '03', 85.0);
