Minimum Invoice Date Query For Client ID
Oct 13, 2014
I have a table with data like the following:
ClientID InvoiceDate
1 2012-01-01
1 2013-01-01
2 2012-01-01
2 2013-01-01
3 2012-01-01
3 2013-01-01
I would like to return a distinct ClientID and also the minimum InvoiceDate for that ClientID, so that the data looks like this:
ClientID InvoiceDate
1 2012-01-01
2 2012-01-01
3 2012-01-01
