Appending to a value

Question

Hello:
I have the following query which translates a column to include "underscores". In addition, at the end of the value, I need to add the following "_v1".
In addition, I need to add two additional texts to precede the value. For example:
The current value looks like this: Retinal Exam.
My current query gives me the following result: Retinal_Exam.
I need the query to give me this result: WM_TMV_Retinal_Exam_v1.
The WM and the TMV are coming from other tables.
Can someone help me fix my query as I can add this extra bit of text?
This is my query:
select global_traittype_description, translate(global_traittype_description,' /-()','_') as traitname
from trait_map_dim
order by global_traittype;I tried a number of things and I keep receiving an "Invalid Character" message.
Thanks for the help.

Hi,
Assuming Column_value 'WM' comes from table_1. Column_1
and column_value 'TMV' comes from table_2.Column_2.
Your query would be something like:
select global_traittype_description,
table_1.Column_1 || '_' || table_2.Column_2 || '_' || translate(global_traittype_description,' /-()','_') || '_v1' traitname
from trait_map_dim, table_1, table_2
where
{join condition of your three tables}
order by global_traittype;
Hope this helps.
