Both methods use simple python code and data insertion is connected MySQL

MySQL connection code is as follows:

pymysql Import 
# Open Database Connectivity parameters were as follows: 
Conn = pymysql.connect (Host = 'localhost', = User 'the root', password '1234', Database = 'pymysql_demo', Port = = 3306) 
Method # using cursor () obtaining cursor operation 
cursor = conn.cursor () 
. 
. 
. 
. 
# close the connection 
conn.Close ()

　

Insert data:

1）

pymysql Import 
Conn = pymysql.connect (Host = 'localhost', = User 'the root', password = '1234', Database = 'pymysql_demo', Port = 3306) 
Cursor = conn.cursor () 

# insert data format is as follows: insert into table (Inserts header) value (corresponding to data) 
SQL = "" " 
iNSERT into User (ID, username, Age, password) value (. 1, 'Rose',. 19, '12345') 
" "" 
# sql statement submitted mapped to the database. 
the cursor.execute (SQL) 
conn.commit () 

# close the connection 
conn.Close ()

　　

　　

2）

pymysql Import 
Conn = pymysql.connect (Host = 'localhost', = User 'the root', password = '1234', Database = 'pymysql_demo', Port = 3306) 
Cursor = conn.cursor () 


# id selected if auto-increment and primary key can be set to null, it automatically increase. 
= SQL "" " 
INSERT INTO User (ID, username, Age, password) value (null,% S,% S,% S) 
" "" 
username = 'Lily' 
Age = 20 is 
password = '666666' 
the cursor.execute ( SQL, (username, Age, password)) 
conn.commit () 


conn.Close ()

　　

　　In many cases, you need to insert the value is not fixed but variable, so we can use this method to insert data.
