Example

```
Table 1

W__ | F__ | C__ | Code
15__ 4___   35__  A0
5___ 1___   2___   A5
8___ 3___   7___   A1

Table 2

W__ | F__ | C__ | Code
15__  4___   35__   NULL
2___   3___ 6___   NULL

Desired output

15, 4, 35, A0
5, 1, 2, A5
8, 3, 7, A1
2, 3, 4, NULL

```

I want to select all rows from Table 1 and append with all rows from Table 2 that do not contain a matching W, F, and C column to anything in table 1. Any help is appreciated. The underscores are only there to make spacing consistent
