READTEXT Into @localvariable

Hi,
How do I get the results of a READTEXT call into a T-SQL local variable?
Thank you,

You can't declare a variable as text, therefore (assuming sql 2000) you are
limited to the maximum size of varchar. You can then chunk the text into
sections using substring e.g.
USE TEMPDB
CREATE TABLE MyTextTable ( TxtCol Text )
DECLARE @.ptrval binary(16)
DECLARE @.varchar varchar(8000)
SET @.varchar = REPLICATE('The quick brown fox jumped over the lazy dog', 200
)
INSERT INTO MyTextTable ( TxtCol ) VALUES ( @.varchar )
SELECT DATALENGTH(TxtCol) FROM MyTextTable
SELECT @.ptrval = TEXTPTR(TxtCol) FROM MyTextTable
SELECT LEN(@.varchar)
UPDATETEXT MyTextTable.TxtCol @.ptrval 7964 0 @.varchar
SELECT DATALENGTH(TxtCol) FROM MyTextTable
GO
DECLARE @.str varchar(8000)
DECLARE @.offset int
DECLARE @.maxlength int
SET @.offset = 1
SET @.maxlength = (SELECT DATALENGTH(TxtCol) FROM MyTextTable)
WHILE @.offset < @.maxlength
BEGIN
SELECT @.str = SUBSTRING(TxtCol, @.offset, 8000 ) FROM MyTextTable
SELECT @.str
SET @.offset = @.offset + 8000
END
DROP TABLE MyTextTable
John|||John,
This is what I needed:
SELECT @.str = SUBSTRING(TxtCol, @.offset, 8000 ) FROM MyTextTable
