如何添加到MySQL中的每一行?

UPDATE table_name SET int_column_value = int_column_value + 10;
UPDATE table_name SET int_column_value = 10 WHERE int_column_value IS NULL;

日期:

UPDATE table_name SET date_column_value = DATEADD(date_column_value, INTERVAL 1 MONTH);

 UPDATE table_name SET column_value = column_value + 10;

update table_name set column_name=column_name+10 where column_name is not null;

应该是这样简单的:

UPDATE some_table SET int_field = int_field + 10
