In the real business of them, there may be late to generate a table (products) backup data each month, this time we might have a table name generated by the table at the end of each month to back up data state, so think most well contains date information, such as products202003,
create procedure proc_name()
begin
DECLARE nowtime char(10);
DECLARE table_name char(30);
SELECT DATE_FORMAT(NOW(),'%Y%m') into nowtime;
select CONCAT('products',nowtime) into table_name;
set @sqlStr=CONCAT('CREATE table if not exists ',table_name,' like products');
PREPARE stmt from @sqlStr;
EXECUTE stmt;
set @insertSql=CONCAT('INSERT INTO ',table_name,' select * from products');
PREPARE stmt2 from @insertSql;
EXECUTE stmt2;
end
This procedure generates a table stored products named reconnection date data on the table, and then copy the data from the master table into the current data table
