SQL Server :: Get Last Rows Of Every Unique CompanyID?

Mar 23, 2011

Lets say I have a Table called: TableA

and values

TableA_ID CompanyID
1 1294
2 1265
3 1294
4 1246
5 1265

I need to get the last inserted row (TableA_ID) of EVERY Unique CompanyID

So output should be

TableA_ID CompanyID
3 1294 (the last row of this CompanyID)
4 1246 (the last row of this CompanyID)
5 1265 (the last row of this CompanyID)

DataSource Controls :: Return Unique Rows : T-SQL Query

Jun 11, 2010

I have an SQL database table like the following:

ID // Code // Shape

The ID is the integer identifier.

On one line the Code may be OX01 and shape Hexagon for example

Then the next line the code is still OX01 but the shape is Triangle.

What I want to do is be able to pull back data for every line that is equal to a unique Code column. in the above example OX01 Hexagon would be returned but not OX01 Triangle.

I've tried using SELECT DISTINCT but it brings back all records and doesn't filter them correctly.

I've considered having another column which could have Child/Parent data so that only the parent is returned but i'm sure there must be a better way of doing this.
