hi,

How do you know that "6U7000000 443 IRA FBO Loelei C Dehart DecD W00001" is 1 row and not any other combination?

Try to add row_number to the query, the row number will give you another group by field.

something like this

select custAcctNo,custID,shortName,accountTitle

from

(select Acmnumber, dataset, stringvalue, row_number() over (partition by Acmnumber, dataset order by FIELD) as rnum from vacmvariables

where acmnumber = 153588)

up pivot ( max (stringvalue ) for dataset in ( custAcctNo,custID,shortName,accountTitle)) as pvt

order by acmnumber

Hi,

I'm happy that I can help.

The row number help with cause we have a new column to group by. If you'll add the rnum to the outer select you'll see how he effects the query.

I need some assistance....I have the screen shot attached below. I would like the output to have column headers 'vessel' and each of the twelve months. I would like to have a 'po number' count for every month for each 'vessel'

Hi and welcome to the forums. It is best if you start your own thread instead of hijacking a 2 year old thread. Also, this is a sql server site, not a MySql site, so you will find that the syntax we come up with will work for sql server. It may not work for MySql. Last but not least, on any technical forum where you post for help you need to provide enough information for people to be able to help. A screen shot of a query does not offer much in the way of detail. You should instead include:

1. Sample DDL in the form of CREATE TABLE statements

2. Sample data in the form of INSERT INTO statements

3. Expected results based on the sample data
