Mysql Data insertion at 10 million levels

At first, I did not expect that the data of the 10 million yuan would be inserted into a single number for only 2 w in half an hour. Later, an SQL batch insert statement was improved. Copy codeThe Code is as follows: --
Insert into table (mobile) values (138000000 );
Insert into table (mobile) values (138000000 );
Insert into table (mobile) values (138000000 );
......

-- Optimized
Insert into table (mobile) values (138000000), (138000000), (138000000 );......

-- After optimization, million data is inserted, including php for data processing, with an overhead of about 6 s.
