Modification and backup, batch processing Sometimes we need to modify and delete database tables and databases, which can be implemented as follows: 1. Add a column:For example, in the mytable table in the previous example, adding a column to indicate whether the table is single or not:Mysql> alter table mytable add column single char (1 ); 2. Modify recordsModify the single record of abccs to "Y ":Mysql> Update mytable set single = 'y' where name = 'abccs '; Now let's see what happene

So we can write this: 1 2 select * FROM 3 ( 4 Select Custid,count (*) through (PARTITION by country) as N ' number of customers ' 5 From sales.customers 6 ) t The clause in parentheses is equivalent to a derived table, and if we do not alias COUNT (*) over (PARTITION by country) Here, then select * does not know which column to remove, so it will g

2003 ' Get_format (date| time| DATETIME, ' EUR ' | ' USA ' | ' JIS ' | ' ISO ' | ' INTERNAL ')Returns a format string. This function is useful when combined with date_format () and Str_to_date () functions. The 3 possible values for the first parameter and 5 possible values for the second parameter produce 15 possible format strings (see the Date_format () function Description table for the descriptor used). Function calls results Get_format
