I'm trying to use the NEWID function in dynamic SQL and get an error
message Incorrect syntax near the keyword 'ORDER'. Looks like I can't
do an insert with an Order by clause.
Here's the code:
SELECT @SQLString = N'INSERT INTO TMP_UR_Randoms( Admit_DOCID,
Client_ID, SelectDate, SelectType,Reco rdChosen)'
SELECT @SQLString = @SQLString + N'(SELECT TOP ' + @RequFilesST + '
Admit_DOCID, Client_ID, SelectDate, SelectType, RecordChosen FROM
FD__UR_Randoms '
SELECT @SQLString = @SQLString + N'WHERE SelectType = ' +
@CodeRevTypeSt + ' AND SelectDate = ''' + @TodaySt + '''' + ' ORDER
BY NEWID())'
execute sp_executesql @SQLString
My goal is to get a random percentage of records.
The full SP follows. In a nutshell - I pull a set of records from
FD__Restart_Pro g_Admit into a temporary table called FD__UR_Randoms.
I need to retain the set of all records that COULD be eligible for
selection. Based on the count of those records, I calculate how many
need to be pulled - and then need to mark those records as "chosen".
I'd just as soon not use the TMP_UR_Randoms table - I went that route
because I ran into trouble with a #Tmp table in the above SQL.
Can anyone help with this? Thanks in advance.

Don't interpolate the values into the query string, but use parameters
instead. This saves you from being entangled in a mess of quotes, and
saves you from a lot of other problems as well.
See here for details: http://www.sommarskog.se/dynamic_sql.html#sp_executesql
....and if you are on SQL 2005, you can use SELECT TOP(@var) in which
cases there is no need for dynamic SQL at all, as far as I can see.

As it turns out, the SelectType, the SelectDate, and the Top XX are
all variables - I posted a shortened version in the 'solution'... I
think the Top XX is the biggest one that makes me have to go for
dynamic SQL.
This isn't going to be run that often (a couple times a month), and
there aren't going to be that many records, so I'm hoping all will be
okay with it as is. Thanks though - and many thanks for the article
link. I started this out originally with parameters, and with the two
small examples in BOL I couldn't get it to work - it sounds like your
article was just what I needed, and will come in handy down the road.
