Hello everybody,

Probably it is very simple but can you please explain me how to filter a table according to a value and show a particular column in the combobox?

For example i have a table like this;


Column 1 | Column 2 | Column 3 | Column 4 | 
-------------------------------------------
A        |   Smth1  |  Smone1  |    45
-------------------------------------------
B        |   Smth2  |  Smone2  |    5
-------------------------------------------
C        |   Smth3  |  Smone3  |    44
-------------------------------------------
A        |   Smth4  |  Smone4  |    46
-------------------------------------------
C        |   Smth5  |  Smone5  |    452
And i want to filter "A" and insert the column 3 values into the combobox list.

Combobox must show Smone2 and Smone4

How can i do that?
