Question

Let’s say we have following table.

UserId | Message
-------|-------------
1      | Hi, have a nice day
2      | Hi, I had a nice day

I need to have all { Hi,-have-a-nice-day-I-had } words separately.
Is there any way to do that ? What if I want to export words from whole database tables ?

Similar results would be also good.

try this:In Sql server 2005 or above

create table yourtable(RowID int, Layout varchar(200))
INSERT yourtable VALUES (1,'hello,world,welcome,to,tsql')
INSERT yourtable VALUES (2,'welcome,to,stackoverflow')


;WITH SplitSting AS
(
    SELECT
        RowID,LEFT(Layout,CHARINDEX(',',Layout)-1) AS Part
            ,RIGHT(Layout,LEN(Layout)-CHARINDEX(',',Layout)) AS Remainder
        FROM YourTable
        WHERE Layout IS NOT NULL AND CHARINDEX(',',Layout)>0
    UNION ALL
    SELECT
        RowID,LEFT(Remainder,CHARINDEX(',',Remainder)-1)
            ,RIGHT(Remainder,LEN(Remainder)-CHARINDEX(',',Remainder))
        FROM SplitSting
        WHERE Remainder IS NOT NULL AND CHARINDEX(',',Remainder)>0
    UNION ALL
    SELECT
        RowID,Remainder,null
        FROM SplitSting
        WHERE Remainder IS NOT NULL AND CHARINDEX(',',Remainder)=0
)
SELECT part FROM SplitSting ORDER BY RowID
