替换删除用于更新MS SQL

您好我有1张大桌子和我做2小表是这样的：替换删除用于更新MS SQL

TABLE BIG 

NAME SURNAME Id_columnX 
tata grgr    
moto hjjj    
oto  kono    
majs grgsgr  35666  
msdfo hjgfjj  27166  
odato kogsno  21899 


TABLE 1 

NAME SURNAME Id_columnX NAME2 
tata grgr    gtata 
moto hjjj    hmoto 
oto kono    koto 


TABLE 2 

NAME SURNAME Id_columnX NAME2 
majs grgsgr  35666  grmajs 
msdfo hjgfjj  27166  hjmsdfo 
odato kogsno  21899  koodato

，我做剧本超过2小表是这样的：

TABLE 1 

DELETE FROM TABLE1 
WHERE Id_columnX LIKE '_%' 

Update TABLE1 
    set NAME = RIGHT(CONCAT(REPLICATE('0', 6), (NAME)), 6) 
    where LEN(+ RTRIM (NAME)) < 6; 

UPDATE [dbo].[TABLE1] 
SET [NAME2] = LEFT([SURNAME], 2) + [NAME] 

UPDATE [dbo].[TABLE1] 
SET [NAME2]=LOWER(LEFT([NAME2],1))+LOWER(SUBSTRING([NAME2],2,LEN([NAME2]))) 




TABLE 2 

DELETE FROM TABLE2 
WHERE Id_columnX NOT LIKE '_%' 

Update [dbo].[TABLE2] 
    set NAME = RIGHT(CONCAT(REPLICATE('0', 7), (NAME)), 7) 
    where LEN(+ RTRIM (NAME)) < 7; 

UPDATE [dbo].[TABLE2] 
SET [NAME2] = LEFT([SURNAME], 1) + [NAME] 

UPDATE [dbo].[TABLE2] 
SET [NAME2]=LOWER(LEFT([NAME2],1))+LOWER(SUBSTRING([NAME2],2,LEN([NAME2])))

我的问题是：我怎么能得到这个：

TABLE BIG 


NAME SURNAME Id_columnX NAME2 
tata grgr     gtata 
moto hjjj     hmoto 
oto  kono     koto 
majs grgsgr  35666  grmajs 
msdfo hjgfjj  27166  hjmsdfo 
odato kogsno  21899  koodato

我不想分裂大表2小表，然后设置设置NAME 2来自DELETE的东西......我不知道我能用什么：如果更新？

感谢您的意见。

就包括在WHERE子句中的所有必要条件，当你更新，像这样：

UPDATE [Big] 
SET name = RIGHT(CONCAT(REPLICATE('0', 6), (name)), 6) 
    WHERE Id_columnX NOT LIKE '_%' AND LEN(RTRIM(name)) < 6;

然后

UPDATE [Big] 
SET name = RIGHT(CONCAT(REPLICATE('0', 7), (name)), 7) 
    WHERE Id_columnX LIKE '_%' AND LEN(RTRIM(name)) < 7;

我不知道情况是否应该在哪里Id_columnX （NOT）LIKE'_％'或WHERE Id_columnX IS（NOT）NULL。无论如何分类表1和2中的记录都应该适用于选择性更新。

运行这两个查询后，表应该完全更新。
