SQL generates auto-sequence numbers with placeholders (masks) that can adjust the placeholder length of the statement

MSSQL statement

--Declaring variables
DECLARE @i int
DECLARE @xh varchar (10)
DECLARE @name varchar (10)
Set @i = 0

--Start the loop to insert the data
While @i < 100
BEGIN

　　　　　　　　　　　　　　　　　　　　　　　
SET @xh = Right ('000000' + CAST (@i as varchar),6)-- number of mask bits
Set @name = ' info ' + CAST (@i as varchar (10))
--print @xh
INSERT into qwe values (@xh, @name, @i)
Set @i [email protected] +1
END

PS: Can change the mask and mask the number of bits to adjust appropriately
