Hello, mysql,
A table contains a column named "mydate".
//Wrong sql statement alter table p_asset add mydate datetime default now(); alter table p_asset add mydate datetime default time(); alter table p_asset add mydate datetime default now; alter table p_asset add mydate datetime default time; alter table p_asset add mydate datetime default date(); alter table p_asset add mydate datetime default datetime();
How can I add the default now value into the specified column?
I try to find in the mysql manual,but in the default value charter,no relative information can be found.
I also know this question is stupid,but hope you help.
Default values must be constants:
http://www.mysql.com/doc/en/CREATE_TABLE.html
To get a column initialized with the time of insertion, you might consider using TIMESTAMP. But be sure to read about its properties and understand how it works:

Best regards.
