腳本從幾個不同的表

Question

還挺新的數據庫腳本改變與不同名稱的列的DB值，

1. 我想一個腳本，該腳本會告訴我的列10的從塔10的。
2. 用於從10列中更改10列的值的腳本。

我知道我可以使用Select語句，但是最佳實踐？

Select 

table1.column1, 
table1.column2, 
table2.column1 
    ...... 
    table100.column100 FROM table1,table2,.....table100; 

，但得到這個錯誤

1.Selecting 10's of columns from 10's of columns -- select * from tablename is good way. 
But this is not good when you consider the query for performance point of view.If your reuirement is to get all the columns of a table then you can use select * from tablename. 

2.This is quite obvious that you have to use all 10 columns if u have to change their values. 
UPDATE tablename SETcol1=value1, 
     col1=value1, 
     col1=value1, 
     .....
