[bug] SQL for currency has CONCAT involved - ansi is partial supported

requirement

need to change columns and views in the SQL and html tables due unsupported CONCAT() function

Justification

In the Currency model we have a sql with concat involved..

SELECT 	m1.iso4217a3 || \":\" || m1.nombre_moneda FROM 

Engine	CONCAT(A,B)	A || B
db2	Yes	Yes
ingres	Yes	No
mysql	Yes	Yes(*)
oracle	No	Yes
postgres	No	Yes
sqlserver	No	N/S
sybase	Yes	Yes

• The || works in MySQL as well but you need to set sql_mode to PIPES_AS_CONCAT
• sqlserver is not in our matrix support data
