1. CREATE Table A CREATE Table A ( Name char (not NULL), ID char (NOT NULL primary key); 2. CREATE TABLE B CREATE TABLE B ( B_name char (not NULL), b_id char (not NULL), Constraint foreign KEY (b_id) references a (ID) on DELETE cascade); 3. After the table is built, insert the data Insert into a values ("111", "1"); Insert into a values ("222", "2"); Insert the following data into B values ("1", "1") in table B Display insert succeeded. Insert the following data into B values ("1",

Inline style: a=1,b=c=d=0 (i.e. 1.0.0.0)2, ID style: Selector with a few ID, 2nd bit add a few 1 such as #header{color:red}, is a=c=d=0,b=1 (that is, 0.1.0.0)3, class, Pseudo-class, and the number of attributes is the third-digit value:. a.b[type= "Text"]:hover{}, the selector has 2 classes, 1 properties, 1 pseudo-classes, so its 3rd bit is 4, a
