Hi,

I have a column with long text, which I would like to split into columns text1, text2, etc by making a split every 250 characters. Then I would like to save text1, text2, etc together with one other variable as a new table. I've tried to write a script (I guess I'll just need 2 lines really?) with which I can implement that in SQL Browser, but haven't succeeded so far. Would anyone know how to do this?
Thanks so much, JZ

;with ce as
(
select i=1, s = substring(str,1,250), id from tbl
union all
select i=i+1, s = substring(str,(i-1)*250+251,250), id from tbl t join cte c on c.var = t.var where len(str) >= ,(i-1)*250+251
)
insert newtbl
select var, seq = i, str
from cte

You can pivot this if you want it in columns but you would then need a maximum size for the string.



==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

Another approach, ion case you are really on SQL 2000 and don't have CTE's available to you
DECLARE @x VARCHAR(255)= 'abcdefghkijlmn';

DECLARE @chunksize INT = 3; -- change to what you want
SELECT
	@chunksize*number+1,
	@chunksize,
	SUBSTRING(@x,@chunksize*number+1,@chunksize) 
FROM
	MASTER..spt_values
WHERE
	[type] = 'P'
	AND @chunksize*number <= LEN(@x);
