SQL Query Last Customer Order Date

[former_member1042939]

Hi,

I am trying to build a query to see the last order date for each customer in our system (along with the contact details for each customer file). All active and inactive customers. Currently the only way I am able to remotely get close to what I need is for it to show every invoice ever placed by each customer and I can get rid of duplicates in Excel but it doesn't leave me with the most recent doc date. I have also tried to set the doc date range to look at certain time periods of activity but that doesn't exclude customers who are more recently active. I have tried to use the Group By function but it goes into error every time. This is what I have so far, but need to just have the most recent doc per customer.

SELECT T1.[DocDate], T0.[CardCode], T0.[CardName], T0.[CntctPrsn], T0.[E_Mail], T0.[MailCountr], T0.[State2], T0.[MailCity], T0.[validFor], T0.[frozenFrom], T0.[FrozenComm] FROM OCRD T0 INNER JOIN INV1 T1 ON T0.[CardCode] = T1.[BaseCard]

I'm sure I'm missing something obvious but I'm not overly familiar with running these reports. Any help would be appreciated. Thank you.
