I tried the version 5.6.0 of Jasperstudio, I use MySQL as the database, it is now possible to see the tables could not see before, but when making inquiries with this visual diagram puts quotes to sql language which marks Error since MySQL does not accept the SELECT field, field FROM table with the quotes and you need to remove them manually. Schedule an example: SELECT "sicdatos"."transfcfe_mstr"."no_transbanco", "sicdatos"."transfcfe_mstr"."no_bancotransf", "sicdatos"."transfcfe_mstr"."no_cuentacfe", "sicdatos"."transfcfe_mstr"."arch_foto", "sicdatos"."transfcfe_mstr"."fecha_censo" FROM "sicdatos"."transfcfe_mstr" as you can see put quotes and quotes should not take for MySQL. Thank you.
