Source: Internet
Author: User

The update statement is enhanced in sql2005. The write function is provided for fields such as nvarchar (max), nvarchar (max), or varbinary (max.

Create table testBIGtext
TestBIGtextId int primary key,
Value varchar (max)

Insert into testBIGtext
Values (1 ,'')

Next, we use write to update the value of the value field:

DECLARE @ offset int
SET @ offset = 0
WHILE @ offset <26
UPDATE testBIGtext
SET value. write (replicate (char (97 + @ offset), 1000), @ offset * 1000,100 0)
WHERE testBIGTextId = 1
SET @ offset = @ offset + 1

After the execution, the value will be 1000 a connected to 1000 B... (aaaa... bbb. ccc ...... zzz)
