替换删除以更新MS SQL

嗨，我有一张大桌子，我做了两张小桌子，像这样：

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

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

我在两张小桌子上做了如下脚本：

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])))

我不想分裂为2个小表大表，然后设置设置名称2，这是从删除的东西来。。。我不知道我能用什么：如果更新

感谢您的意见。

更新时，只需在WHERE子句中包含所有必要的条件，如下所示：

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

;WITH TABLE_BIG(NAME,SURNAME,Id_columnX )

)
,TABLE1(NAME,SURNAME,Id_columnX, NAME2)
As

,Final AS (
        SELECT SURNAME,NAME2  FROM TABLE1       
        UNION ALL       
        SELECT SURNAME,NAME2  FROM TABLE2
        )

SELECT NAME ,SURNAME,Id_columnX ,NAME2
FROM (
    SELECT B.NAME
        ,b.Id_columnX
        ,f.SURNAME
        ,f.NAME2
    FROM Final F
    INNER JOIN TABLE_BIG B ON b.SURNAME = f.SURNAME
    ) AS Dt

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

UPDATE[Big]
SET name=RIGHT（CONCAT（REPLICATE（'0'，6），（name）），6）
其中Id_columnX不象“u%”和LEN（RTRIM（name））<6；

然后

UPDATE[Big]
SET name=RIGHT（CONCAT（REPLICATE（'0'，7），（name）），7）
其中Id_columnX类似于“%”和LEN（RTRIM（name））<7；

我不确定该条件应该是Id_columnX（不）像“u%”的位置还是Id_columnX（不）为NULL的位置。无论对表1和表2中的记录进行分类有什么好处，都应该适用于选择性更新

在运行这两个查询之后，应该完全更新表
