I have a small temp table with 2 columns: ErrorName and Value.

```
ErrorName|Value
---------|-----
Error1   |3
Error2   |2
Error3   |2
Error1   |1
Error2   |1

```

I want to sum up the value field based on the ErrorName and return something like this:

```
Error1   |4
Error2   |3
Error3   |2

```
