HI
First I must say that Im just a rookie on SQL.
At this moment I'm creating a website using Joomla 2.5
So I use PHPmyadmin
I wonder if the code you submited could be imported into the phpmyadmin (as a sql file) to create a table that includes a field with random string each time a new record is created in the database.
I used a notepad and save the following as a sql file
Create View OneRandomString20
AS
with
a1 as (select 1 as N union all
select 1 union all
select 1 union all
select 1 union all
select 1 union all
select 1 union all
select 1 union all
select 1 union all
select 1 union all
select 1),
a2 as (select
1 as N
from
a1 as a
cross join a1 as b),
a3 as (select
1 as N
from
a2 as a
cross join a2 as b),
a4 as (select
1 as N
from
a3 as a
cross join a2 as b),
Tally as (select
row_number() over (order by N) as N
from
a4)
, cteRandomString (
RandomString
) as (
select top (20)
substring(x,(abs(checksum(newid()))%36)+1,1)
from
Tally cross join (select x='0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ') a
)
select
replace((select
',' + RandomString
from
cteRandomString
for xml path ('')),',','') AS Results;
GO
CREATE FUNCTION fn_RandomString()
returns varchar(20)
AS
BEGIN
Declare @results varchar(20)
SELECT top 1 @results = Results from OneRandomString20
return @results
END
GO
select dbo.fn_RandomString()

But I got the following error as result of the import
