Refresh variable according to the data schema

Question

Hello guys,
First post, fairly new to ODI and looked around for a while before posting.
We are trying to create a variable that runs a SQL command to return a value from an ORACLE table column.
#VAR1 = select column_value from <schemaname>.<tablename> where anothercolumn value = '';
we do not want to hard code our schemaname as it can change once move to QA.
Is there a way we can say #VAR1 = select column_value from "#VAR2" .<tablename> where anothercolumn value = ''
and
"VAR2 = <%=odiRef.getObjectName( "L" , "TABLENAME" , "LOGICALSCHEMANAME" , "DEV" , "D" )%>
Can anyone point to any suggestions or learning material?
Thanks in advance for your time.

Thanks Cezar,
Its working to the point that I have a variable to retrieve the schema name
v_Schema_Name = select '<%=odiRef.getSchemaName("LS_Name" , "CTXT_DEV" , "D" )%>' from dual
How do I correctly embed this code into another variable?????
SELECT column_1_val FROM #v_MASTER_SCHEMA_NAME .tablename WHERE col2_name = 'COL_2_VAL' in the refresh tab, its giving me
"invalid character error."
Even this way, once it works, I will have to manually/thru package refresh the schema name variable once we move to new environment.
Any ideas to handle the change dynamically????
Thanks
